5 Key Steps: Keeping Your Roller Press Granulator in Top Condition

A well-maintained roller press granulator is like a trained athlete – regular inspections, proper care and timely adjustments are key to maintaining peak performance. Master these five maintenance essentials and your equipment will reward you with longer service life and more consistent product quality.

Fertilizer granule compaction is a critical process in modern agriculture, efficiently transforming dust into valuable nutrients. The roller press granulator is the core machine for this operation, but its performance hinges on consistent maintenance. Understanding the key steps to prevent wear and ensure optimal function is essential for any operation seeking to maximize output and equipment longevity.

1. Establish Regular Inspection Routines

  • Daily checks: Quick inspection of feeding system and conveyor operation before startup
  • Weekly focus: Thorough examination of roller surface wear; address immediately if grooves exceed 1mm wear
  • Monthly comprehensive: System check of discharge unit wear and conveyor belt condition
  • Quarterly major inspection: Full assessment of transmission components, ensuring bearing temperatures stay below 70℃ safety threshold

2. The Art of Equipment Cleaning

After each production run, clean your equipment as thoroughly as a chef cleans their kitchen. Use compressed air or water rinsing (for non-water-soluble materials) to remove residues. Special reminder: when changing material types, deep cleaning is mandatory to prevent cross-contamination. The cleaning process also presents an excellent opportunity to spot potential issues.

3. Lubrication: The “Lifeline” of Your Machine

Just as the human body needs regular hydration, equipment requires scientific lubrication. Replace gear oil every 1000 operating hours for reducers, and replenish bearing grease every 500 hours. Remember: using the correct type and amount of lubricant is the secret to reducing wear and extending lifespan.

4. Precision Roller Gap Adjustment

Adjusting the roller gap requires the patience and precision of a watchmaker. After shutdown and power disconnect, make micro-adjustments (1°-2° each time) via eccentric sleeves to maintain the ideal 0.3-1mm gap. Always manually test and observe granule formation after adjustment – multiple fine-tunings may be needed for perfect results.

5. Pocket Alignment: The Ultimate Test of Precision

Pocket alignment is the subtle art of granulation. Axial alignment typically only requires initial setup, while circumferential alignment demands more delicate adjustments. Use the cardboard test method, making only 0.5°-1° adjustments each time, until achieving perfect alignment – much like calibrating precision instruments.

Remember: Preventive maintenance is always more economical than major repairs. Invest time in these routine maintenance practices, and your granulator will repay you with higher efficiency and longer service life.

Drum Granulator: A Quartet of Process Innovations

In modern fertilizer production, rotary drum granulators are redefining granulation standards with four innovative features. How do these carefully designed functions work together to create energy-efficient production miracles?

Drum granulators are commonly used in organic fertilizer production because they efficiently form moist organic material into uniform granules through a rotating drum mechanism. They are a key component in organic fertilizer production equipment, which also includes mixers, crushers, dryers, and screening equipment. While granulators specialize in granulation, complete production lines (organic fertilizer production equipment) integrate multiple steps to transform raw organic waste into high-quality fertilizer.

“From steam conditioning to self-cleaning design, each innovation makes granulation more precise and efficient”

Intelligent Steam Conditioning System

The revolutionary steam injection technology acts like precise “thermal therapy” for materials. Steam penetrates the material bed, raising temperature while dissolving salts to form a liquid phase film, enabling ideal liquid phase conditions at low moisture content. This innovation reduces drying evaporation water by 40% and energy consumption by 35%.

⚗️Controlled Ammoniation System

Ammonia gas can be precisely introduced into the drum as needed to promote chemical reactions. This controlled ammoniation technology acts like a “chemical catalyst”, not only adjusting product pH but also improving granule structure, enhancing slow-release performance by 30%.

Self-Cleaning Liner Design

The special rubber or polypropylene liners embedded in the drum wall, combined with cleverly designed air holes, form an intelligent self-cleaning system. When liners rotate to the top, they sag under their own weight, causing adhered materials to fall off automatically. This “self-renewal” mechanism solves traditional granulator sticking problems, reducing maintenance costs by 60%.

Extensive Material Adaptability:

Low-solubility Materials High-solubility Materials Organic Matter Trace Elements

Whether it’s poorly soluble potassium sulfate and potassium chloride, highly soluble urea and ammonium nitrate, or various organic materials and trace elements, this system handles all perfectly. This “non-picky” characteristic reduces formula changeover time by 80%.

Four innovations, four advantages – the drum granulator is driving fertilizer production toward greater efficiency and intelligence with its technological charm.

Roller Compaction Granulator: Which Industries Can’t Live Without It?

In modern industrial production, the roller compaction granulator acts like an “all-round player”, demonstrating remarkable capabilities across various fields thanks to its unique dry granulation technology and wide material adaptability. How exactly is this magical equipment transforming our production processes?

The “fertilizer compaction machine” and “roller compaction granulator” are essentially the same equipment, both using roller compaction technology to produce fertilizer granules without liquid binders. “Fertilizer production machine” is a broad term encompassing all equipment used in fertilizer manufacturing, while the “Fertilizer Granules Compaction Machine” specifically refers to the compaction granulation equipment within this production line. The compaction machine is thus a specialized component of the complete fertilizer production system.

Revolutionizing Agriculture

In fertilizer production, the roller compaction granulator shows astonishing versatility:

  • Handles all types of fertilizers from low concentration (20%) to high concentration (over 60%)
  • Easily processes single fertilizers like ammonium chloride and ammonium sulfate
  • Excels in producing compound fertilizers including organic, inorganic, biofertilizers and magnetized fertilizers

Particularly for potassium fertilizer granulation, it successfully solves the moisture absorption and caking problems of traditional methods, producing potassium fertilizer granules with excellent flowability and low hygroscopicity, filling a domestic technology gap. More impressively, it can precisely adjust NPK ratios according to different crop needs, providing “customized nutrition” for everything from rice and wheat to fruits and vegetables.

Cross-Industry “Multitasker”

Beyond agriculture, this remarkable equipment shines in other sectors:

Pharmaceutical Industry: Its gentle dry process perfectly preserves drug activity, ensuring both stability and uniformity in granulating traditional Chinese medicine particles and Western drug tablet materials.

Chemical Industry: From pigments (titanium dioxide) to detergents (laundry powder) and automotive exhaust catalysts, various special materials can be shaped into ideal granules.

Feed Industry: Transforms raw materials like corn and soybean meal into nutritionally balanced pellet feed, improving storage and transportation while reducing waste by up to 30%.

Environmental Applications: Acts as an “alchemist” for industrial dust – repurposing waste materials like iron-containing dust from foundries and lead-zinc-aluminum dust into usable granules, solving pollution problems while achieving resource recycling.

From farm fields to pharmaceutical workshops, from chemical plants to livestock farms, the roller compaction granulator is quietly transforming production methods across multiple industries with its “multi-purpose” capabilities. With increasingly stringent environmental requirements, this green granulation technology is destined for even broader applications.

Disc Granulator: The Core Powerhouse of Fertilizer Production

In modern fertilizer production lines, the disc granulator acts like a skilled “magician,” transforming various raw materials into perfectly uniform granules. As the core equipment for producing organic fertilizer, organic-inorganic compound fertilizer, chemical fertilizer, and biofertilizer, it is revolutionizing the entire fertilizer manufacturing industry.

When organic fertilizer processed by disc granulator is applied to soil, the organic matter content increases significantly, followed by an increase in soil organic nitrogen. This virtuous cycle not only improves soil structure but also creates an ideal environment for crop growth. The three major advantages of disc granulation—uniform particles, easy moisture control, and high granule strength—make it the preferred choice for fertilizer manufacturers.

The Ingenious Combination of Disc Granulation Line

A complete disc granulation production line is a perfect example of multiple precision equipment working in harmony. Each machine plays an indispensable role in ensuring the excellent quality of the final product:

1. Disc Granulator – The heart of the production line, responsible for transforming mixed materials into uniform granules

2. Horizontal Mixer – Ensures thorough and uniform mixing of various raw materials

3. Drum Screening Machine – Precise grading to ensure consistent particle size

4. Coating Machine – Provides a “protective coat” for granules to prevent caking

5. Multiple Silos Single Weigh Static Automatic Batching System – Accurately controls formula ratios

6. Automatic Packing Machine – Efficiently completes product packaging

Why Choose Disc Granulation Technology?

Compared with traditional granulation methods, disc granulation technology offers incomparable advantages. Its unique tilted rotating design creates ideal rolling motion of materials in the disc, resulting in uniform granulation. Operators can easily control particle size and moisture content by adjusting parameters such as disc inclination angle, rotation speed, and water spray volume to meet different customer requirements.

Even more exciting is the disc granulator’s strong adaptability to raw materials—whether powdered organic matter or chemical materials, it can handle them perfectly. This flexibility allows manufacturers to quickly switch between different product formulations to seize market opportunities.

Investing in a disc granulation production line is not just about purchasing equipment; it’s about injecting strong momentum into your company’s future development. In today’s world of increasingly stringent environmental requirements and booming organic agriculture, this efficient and flexible production system will become your secret weapon to conquer the market!

The Silent Revolution: How Tooth Mixer Granulators Are Changing the Game

Toothed agitator granulators, also known as agitator granulators, are revolutionizing the granulation industry with their unique advantages. Unlike traditional roller granulators or rotary drum granulators, these machines offer superior mixing efficiency, uniform particle size distribution, and reduced energy consumption. Their innovative technology combines gentle material handling with high productivity, making them ideal for organic fertilizer production and other applications where traditional granulation methods are insufficient.

Tooth Mixer Granulator: The Gentle Yet Efficient Particle Artist

In the world of particle manufacturing, one machine is quietly rewriting the rules—it doesn’t rely on brute force compression, but instead creates perfect granules through the “art of mixing”. This is the tooth mixer granulator, a mechanical artist that transforms rough granulation processes into elegant “particle dances”.

A Mechanical Ballet

Imagine this scene: Uniformly mixed materials enter the granulation cylinder and are immediately embraced by stainless steel mixing teeth rotating at high speed. These carefully designed tooth structures, like ballet dancers’ arms, guide the materials through complex rotations, throws, and agglomerations at hundreds of revolutions per minute. During this process, friction, centrifugal force, and the material’s own viscosity work in perfect harmony to gradually shape loose powder into uniformly sized spherical granules.

What Makes It Special?

Unlike traditional extrusion granulators, the tooth mixer granulator’s greatest advantage lies in its “gentle processing” characteristics. Instead of roughly crushing materials, it completes granulation through continuous gentle mixing, making it particularly suitable for delicate raw materials—whether highly viscous organic mixtures or special materials containing plant fibers, all can maintain their original properties in this mild environment.

Even more impressive is that this granulation method produces particles with excellent roundness and uniformity, so smooth they hardly require subsequent polishing. Moreover, without complex compression devices, equipment maintenance becomes exceptionally simple, and operational noise is significantly reduced.

The Perfect Choice for Small-to-Medium Production

While perhaps not suitable for ultra-large-scale production, tooth mixer granulators demonstrate remarkable adaptability in low-to-medium output scenarios. From organic fertilizers to biomass pellets, from feed additives to special chemical products, it can handle them all with ease. For producers pursuing “small but beautiful” manufacturing, this is undoubtedly the ideal granulation solution.

With advancements in materials science and manufacturing processes, new-generation tooth mixer granulators are becoming smarter and more efficient. Perhaps in the near future, this elegant granulation method will become the preferred choice for more industries, completely changing our understanding of particle manufacturing.

Characteristics and advantages of a new type of organic fertilizer two in one granulator

The new type of organic fertilizer two in one granulator is a molding machine that can manufacture materials into specific shapes. The combination of this granulation method results in higher ball forming rate, more beautiful particles, and energy saving. This machine is one of the key equipment in the compound fertilizer industry, suitable for cold and hot granulation, as well as large-scale production of high, medium and low concentration compound fertilizers.

The new organic fertilizer two in one granulator has specificity for the granulation of livestock and poultry manure, composting fertilizers, green manure, sea manure, cake manure, peat, soil and miscellaneous fertilizers, three wastes, microorganisms, urban household waste, and organic fermented fertilizers. This machine is particularly suitable for granulating lightweight fine powder materials. The finer the basic particles of fine powder materials, the higher the sphericity of the particles, and the better the ball forming quality. Typical application materials: chicken manure, pig manure, cow manure, charcoal, clay, kaolin, etc.

Advantages of the new organic fertilizer two in one granulator:

1. Concentrated particle size distribution, easy to control: Compared with natural agglomeration granulation devices such as rotary disc granulators and drum granulators, the particle size distribution is concentrated.

2. High organic content: The produced particles are spherical. The organic content can reach up to 100%, achieving pure organic granulation.

3. High efficiency: High efficiency, easier to meet the requirements of large-scale production.

4. Granulation without edges and corners, extremely low pulverization rate: spherical particles have no sharp angles after granulation, so the pulverization rate is extremely low.

The working principle of the new organic fertilizer two in one granulator is to use the high-speed rotating mechanical stirring force and the resulting aerodynamic force to continuously mix, granulate, spheroidize, and compact fine powder materials in the machine, thus achieving the purpose of granulation. The particle shape is spherical, with a sphericity of ≥ 0.7, a particle size generally between 0.3 and 3 millimeters, and a particle formation rate of ≥ 80%. The size of the particle diameter can be adjusted appropriately by the material mixing amount and the spindle speed. Generally, the lower the mixing amount, the higher the rotation speed, and the smaller the particle, and vice versa.

Skills and experience in purchasing granulators in Organic fertilizer production line

Pigs are full of treasures, and even pig manure is an excellent fertilizer for agriculture. Raising pigs to make money, pig manure to fertilize the fields. A virtuous ecological agricultural cycle is characterized by the abundance of grains, pigs, feces, and grains. Pig manure has a finer texture and contains more organic matter and nitrogen, phosphorus, and potassium nutrients. It decomposes slowly and is suitable for use as a base fertilizer. One pig’s manure can increase grain production by 200 to 300 kilograms.

The pig manure Organic fertilizer granulator adopts a new technology of positive pressure jet negative pressure air induction, which continuously and evenly sprays the dry hot air to the Accumulation zone of granular fertilizer. The calorific value is fully exchanged. The human manure Organic fertilizer granulator is energy-saving and efficient. The exchanged water vapor, under the combined action of positive pressure hot air flow and negative pressure induced air flow, continuously accumulates moisture in the upper half of the dryer and is quickly drained. In the traditional drying process, granular fertilizers always exchange calorific value with hot air containing a large amount of water, resulting in a significant reduction in drying efficiency. Especially for drying Organic fertilizer, two-stage drying is often used, resulting in high operating costs. This machine has the characteristics of advanced technology, unique structure, high drying efficiency, large production capacity, low production cost, and reliable operation. Equipped with a cold and hot air conditioning supply system, it can control the drying temperature to ensure the activity of functional bacteria in biological fertilizers.

5. Compare manufacturers to see their industry processing experience. It also depends on whether it is a manufacturer and not to be fooled by some unscrupulous vendors, becoming “middlemen” with high prices and low quality.

6. According to the after-sales service of Organic fertilizer granulator equipment manufacturers, Organic fertilizer processing is a one-time production and long-term processing process, and after-sales service is very important.

The principle and advantages of processing fertilizer with roller extrusion granulator

The production process of organic fertilizer equipment is mainly that the previously fermented organic fertilizer raw materials are crushed, screened, and then measured, batched and mixed (or further dried to produce powdered organic fertilizer) with binder and other ingredients according to the ratio requirements in the automatic batching mixing system. The fully mixed material is fed into the granulator evenly and continuously by the belt conveyor.

Common organic fertilizer granulation processes are: drum granulator, disc granulator, and organic fertilizer granulation mainly uses roll press granulator, drum granulator, disc granulator, etc

The roll press granulator will extrude the powder forming, crushing, finished product screening and other processes into one, compact structure, convenient operation. The powder from the hopper is continuously and evenly added to the top of the two rolls. Under the action of continuous rotation of the extrusion roll, the powder is bitten into the two rolls and extruded into the board, and then falls off under the centrifugal action and the board’s own gravity. The shaping wheel with teeth and claws is separated into particles and then enters the dividing screen. The powder under the screen is sent back to the material, the grain on the screen is rolled by the roller, the acute Angle of the particle is ground, and the discharge port on the screen bucket is discharged into the packaging.

Roller extrusion granulator has the following advantages : 1. Cycle operation, continuous production and high output of finished products; 2. The material is forcibly compressed and formed by mechanical pressure without any additives, thus ensuring the purity of the product. 3. Particle strength can be adjusted, and finished product strength can be controlled by adjusting the pressure of the roller; 4.Extrusion granulator is suitable for a variety of raw materials , particle strength can be adjusted according to different materials. 5. Compact structure, easy maintenance, simple operation, short process, low energy consumption, high efficiency, low failure rate.

How does wet Organic fertilizer granulator produce fertilizer?

Step 1 Prepare

You need to ferment, crush, and mix the organic material before granulating. Inorganic materials need only be ground and mixed into powder. Huaqiang Heavy Industry provides you with quality composters, fertilizer breakers and fertilizer mixers to complete the work.

2. Wetting process

Add just the right amount of adhesive to help with clumping, a process you can also call wetting. You can spray the adhesive solution into the machine or add the liquid in foam form. The type of adhesive solution varies from material to material. There are two kinds of solvents, water or organic. An aqueous solution is cheap and safe, but takes longer to dry. Organic solvent volatile, suitable for moisture sensitive materials. But they are more expensive and bad for the environment. Wet granulators use steam and steam wetting materials, which are inexpensive and environmentally friendly.

3. Granulation

After the raw material becomes wet and some chemical reactions occur, the powder begins to roll with the organic fertilizer pelletizer. Under the combined action of centrifugal force and interparticle compaction, the material gradually forms the particles we want.

4. Drying process

There is still a lot of water in the granulated product. You need to dry them to make them easy to carry or store. At this time, a rotary drum dryer is needed to quickly complete the work. It will dry the particles evenly.

5. Cooling process

Long exposure time of fertilizer particles under high temperature drying is unfavorable. So you need a drum cooler to preserve nutrients and active substances in the particles. Our coolers can do the job quickly and reliably.
