Windrow compost turning machines offer a standardized, complete process for recycling chicken manure

fertilizer granulator Oct 29, 2025

Chicken manure, a common waste product in the livestock industry, is rich in nitrogen, phosphorus, potassium, and organic matter. However, its direct use without treatment can easily cause soil contamination and crop burn. The windrow compost turning machine uses a scientific processing process to transform chicken manure into high-quality organic fertilizer, effectively recycling pollutants.

The first step is raw material pretreatment. Fresh chicken manure has a moisture content of approximately 60%-70% and a low carbon-nitrogen ratio. Straw, sawdust, and other auxiliary materials are added proportionally to adjust the carbon-nitrogen ratio to 25-30:1, and the humidity is controlled at 55%-65% to create a suitable environment for aerobic microbial fermentation. After mixing, a loose pile is formed.

The second step is pile construction and initial fermentation. The mixed material is piled into a long, 3-5 meter wide and 1-1.5 meter high pile. The windrow compost turning machine, with its crawler tracks, can operate directly on the soft pile, avoiding sinking. After the equipment is started, the turning gears penetrate deep into the pile, thoroughly mixing the bottom and top layers. Air is introduced simultaneously, promoting the growth of aerobic microorganisms and rapidly raising the pile temperature to above 55°C.

The third step is continuous turning and temperature control. During the fermentation period, the compost turner operates at a set frequency: once daily in the early stages and every other day in the later stages. This turning process not only replenishes oxygen and removes fermentation waste gases, but also stabilizes the pile temperature at 55-65°C. This temperature effectively kills harmful substances such as E. coli and roundworm eggs in the chicken manure, while also accelerating the decomposition and conversion of organic matter.

The entire processing cycle takes approximately 25-35 days. After being processed by the windrow compost turner, the chicken manure is transformed from sticky, foul-smelling waste into a loose, odorless, and mature material. It can then be crushed and screened to produce organic fertilizer.

A brief discussion on the key role of extrusion in the organic fertilizer industry

fertilizer granulator Oct 28, 2025

In organic fertilizer production lines, there’s a seemingly simple yet crucial process: extrusion granulation. It transforms loose, uneven powdered organic raw materials into uniform, solid granules. This isn’t just a change in form; it’s a crucial step in improving the quality and modernizing the development of organic fertilizer.

Although rich in nutrients, unprocessed powdered organic fertilizer faces numerous challenges in practical application. First, its low density and bulk increase storage and transportation costs. Second, during application, powdered fertilizer is easily dispersed by the wind, resulting in fertilizer loss and environmental pollution. Extrusion technology specifically addresses these issues.

The extrusion process applies tremendous pressure to a fertilizer granulator, forcing the fine fertilizer powder through a specialized die, where it is squeezed into uniform, high-density, and strong granules.

The widespread adoption of extrusion granulation technology marks a significant shift in the organic fertilizer industry from extensive to refined, and from traditional to modern. This enables the standardization and commercialization of organic fertilizer products, shedding their image as “earth-based fertilizer” and making them more readily accepted and trusted by large-scale farms and specialized agricultural practitioners.

In short, these tiny fertilizer pellets embody not only rich organic matter but also the wisdom of modern processing technology. Extrusion molding, as a core component, continues to provide solid technical support for improving quality, increasing efficiency, and promoting green development in the organic fertilizer industry.

New type organic fertilizer granulator: Core equipment for efficient organic fertilizer conversion

fertilizer granulator Oct 27, 2025

With the development of organic agriculture, the diversification and high moisture content of organic fertilizer raw materials (such as straw, livestock and poultry manure, and mushroom residue) have driven technological upgrades in new type organic fertilizer granulators. Their optimized design, tailored to the characteristics of these raw materials, has significantly improved production efficiency and the quality of the finished product.

The new type organic fertilizer granulator features a new raw material conditioning system and an anti-sticking device. The conditioning system precisely controls the addition of steam or warm water to adjust the high-moisture organic fertilizer raw materials to a suitable moisture content for granulation (40%-50%), preventing clumping and loose granules. The anti-sticking device sprays a special wear-resistant coating on the inner wall of the granulation chamber, reducing the stickiness of the organic fertilizer raw materials and reducing cleaning frequency.

In terms of workflow, pre-treated organic fertilizer raw materials first enter the conditioning system for humidity and temperature adjustment before being transported to the granulation chamber. The spiral or extrusion mechanism within the granulation chamber mechanically compresses the raw materials into granules. The granules are then trimmed to a uniform size by a cutting device before entering a cooling system for final shaping.

The core value of the new type organic fertilizer granulator lies in its ability to efficiently process highly viscous and high-moisture organic fertilizer raw materials. The resulting granules are high in strength and water-solubility, while also reducing raw material waste. This equipment provides support for large-scale, high-quality production in the organic fertilizer industry.

Double roller press granulators: A key force driving green upgrades in the fertilizer industry

fertilizer granulator Oct 24, 2025

The application of double roller press granulators(fertilizer compaction machines) is reshaping the fertilizer production landscape in multiple dimensions and becoming a crucial support for sustainable agricultural development. Their most significant value lies in their waste resource utilization, transforming organic waste such as livestock and poultry manure and straw into granular fertilizer, significantly reducing reliance on chemical fertilizers.

On the production side, this double roller press granulator offers particularly outstanding environmental advantages. The ambient temperature granulation process eliminates the need for fuel oil or gas drying, eliminating the three wastes emitted throughout the process and eliminating the secondary pollution associated with traditional composting. Furthermore, granulation results in a more uniform nutrient distribution and optimal bulkiness in the fertilizer, increasing plant absorption by over 15% compared to traditional bulk fertilizers and reducing dust loss during transportation and storage.

Equally crucial is its industrial adaptability: A single unit can be used for small production lines, or it can be combined into large-scale units with an hourly output of 50 tons, flexibly meeting diverse scale requirements. From rare earth fertilizers and potash fertilizers to bio-organic fertilizers, double roller press granulators can accommodate a wide range of formulations and even fills a technological gap in the granulation of some specialty compound fertilizers. This combination of flexibility and environmental protection accelerates the transformation of traditional fertilizer production towards green and efficient production.

Windrow compost turning machines: Breaking site constraints and adapting to flexible fermentation

fertilizer granulator Oct 23, 2025

The core of aerobic fermentation of organic fertilizers lies in uniform oxygen supply and temperature-controlled composting. The site adaptability of compost turning equipment directly determines fermentation efficiency and production flexibility. Windrow compost turning machines, with their trackless mobility and all-terrain adaptability, are a perfect fit for the diverse fermentation scenarios in the fertilizer industry.

From a structural perspective, the core advantage of windrow compost turning machines lies in the synergy between their crawler chassis and flexible turning mechanism. Their wide rubber tracks provide a large contact area and low ground pressure, preventing the vehicle from getting stuck even in muddy composting areas or gravel surfaces after rain, eliminating the need for pre-leveling. The chassis’ steering system supports 360° steering, making it easy to navigate obstacles such as raw material piles and equipment around the fermentation area.

In terms of the turning mechanism, most windrow compost turning machines are equipped with double-auger or blade-type turning components, capable of turning compost up to 1.2-2 meters deep and covering compost piles up to 3-5 meters wide. During operation, the equipment slowly moves along the fermentation pile. The turning components throw the bottom material upward and disperse it to the sides, creating a “rolling up and down, mixing side to side” effect. This not only provides sufficient oxygen for aerobic bacteria but also quickly dissipates the heat generated by fermentation.

For fertilizer companies, the value of a windrow compost turning machine lies not only in its flexibility but also in its ability to accommodate multiple fermentation batches. For example, the same site can simultaneously process both a “fresh feed pile” and a “mature compost pile,” allowing the equipment to flexibly switch between different piles, resulting in fermentation efficiency improvements of over 30% compared to track-type compost turners.

Amid the rise of ecological agriculture and the continued surge in demand for organic fertilizer, new type organic fertilizer granulators, leveraging technological innovations from traditional equipment, have become key equipment for the fertilizer industry, addressing challenges in organic fertilizer granulation and promoting green production.

The most prominent advantage of the new type organic fertilizer granulator is its adaptability to organic fertilizer raw materials. Organic fertilizer raw materials, primarily derived from livestock and poultry manure, straw, and food waste, often exhibit large moisture fluctuations, high fiber content, and prone to clumping. By optimizing the conditioning system and granulation structure, the new equipment can flexibly adjust the raw material moisture and temperature. This allows for uniform granulation even with high-moisture, high-fiber raw materials, significantly improving granulation efficiency and effectively reducing raw material waste.

The new type organic fertilizer granulator is also known for its “green and efficient” design. By upgrading its transmission system and adding a dust collection device, the new equipment achieves low energy consumption and low pollution while improving production efficiency.

Furthermore, the new type organic fertilizer granulator can help enhance the competitiveness of organic fertilizer products. The organic fertilizer particles it produces have uniform density, moderate hardness, and are not easy to break; more importantly, the low-temperature granulation process of the new equipment can maximize the retention of beneficial microorganisms and active ingredients in the organic fertilizer, ensuring a longer-lasting fertilizer effect.

Double roller press granulators are an efficient and stable choice for fertilizer granulation

fertilizer granulator Oct 21, 2025

In fertilizer production, the granulation process directly impacts fertilizer application convenience, storage stability, and nutrient utilization. Due to its unique technological advantages, double roller press granulators (commonly known as fertilizer compaction machines) are the preferred equipment for many production scenarios. They can transform a variety of fertilizer raw materials into uniform granules without complex pretreatment, offering both adaptability and practicality.

The operating principle revolves around “physical extrusion.” Crushed and mixed fertilizer raw materials are conveyed between two pairs of counter-rotating extrusion rollers at the core of the equipment. Under pressure from the roller surfaces, the raw materials are compressed into continuous flakes. These flakes then enter a crushing unit, breaking them into irregular particles. Screening equipment then selects the finished product that meets the required particle size.

The core advantages of double roller press granulators lie in their flexibility and energy efficiency. Requiring no binders, granulation relies solely on the raw materials’ inherent physical properties, preserving the natural properties of organic fertilizers or the nutrient purity of compound fertilizers. This eliminates the high-temperature drying step required in traditional granulation. Whether processing organic fertilizer, compound fertilizer, or functional bio-fertilizer, stable granulation can be achieved by simply adjusting parameters such as extrusion pressure and roller speed, providing an efficient solution for fertilizer production.

Bio-organic fertilizer equipment selection and maintenance: Helping reduce costs and increase efficiency

fertilizer granulator Oct 20, 2025

For bio-organic fertilizer manufacturers, selecting and effectively utilizing bio-organic fertilizer equipment is crucial for achieving sustainable profitability.

When selecting equipment, consider your production capacity and the characteristics of your raw materials. If your company uses livestock manure as its primary raw material, you should prioritize equipment with strong pretreatment capabilities to avoid high moisture content that could affect fermentation. If your production capacity is under 5,000 tons/year, you can choose small or medium-sized complete sets of equipment to reduce initial investment. If your production capacity exceeds 10,000 tons, you should consider highly automated production lines to reduce labor costs.

Secondly, pay attention to the bio-organic fertilizer equipment’s durability. Equipment for core processes like fermentation and granulation should be constructed of corrosion and wear-resistant materials to withstand the corrosive nature of organic fertilizer raw materials and extend their service life.

Daily maintenance is equally crucial. After use, promptly clean any residual material from components like fermentation tanks and granulators to prevent it from clumping and becoming moldy, potentially contaminating the raw materials during the next use. Regularly check the lubrication of the equipment’s transmission components. Oil depletion can lead to increased wear and tear, increasing the likelihood of failure.

Scientific selection and operation and maintenance can not only reduce the downtime of bio-organic fertilizer equipment and ensure production continuity, but also reduce maintenance costs and improve product qualification rate.

Regularly clean debris from the travel tracks and crawler tracks to prevent jamming. If the double screws compost turning machine deviates, adjust the track parallelism or crawler track tension promptly to ensure smooth movement.

3.Electrical System Safety

Fermentation workshops are characterized by high humidity. Regularly check the seals of motors and control cabinets to prevent moisture-induced short circuits. Clean dust from electrical components, check for loose connections, and tighten terminal blocks. Perform a no-load test run monthly to test the operating status of motors and inverters. Detect and address any anomalies promptly to avoid prolonged downtime caused by electrical failures.

How can routine drum fertilizer dryer operation and maintenance achieve energy savings and cost reduction?

fertilizer granulator Oct 17, 2025

Drum fertilizer dryers account for 25%-30% of a fertilizer production line’s total energy consumption. Whether routine operation and maintenance are effective directly impacts a company’s operating costs.

1. Accurate Maintenance of Thermal Efficiency

Hot air is the core energy source of a drum fertilizer dryer. The pipes connecting the hot air furnace and the drum must be regularly inspected. Damaged pipe insulation can lead to heat loss (up to 10% or more) and require prompt repair or replacement. Clean accumulated slag in the hot air furnace to ensure complete fuel combustion, increase thermal efficiency to over 75%, and reduce fuel waste.

2. Dynamic Adjustment of Drum Operating Parameters

Adjusting operating parameters based on changes in raw material moisture content can avoid inefficient energy consumption. When the moisture content of the wet material is low, appropriately reduce the hot air temperature and increase the drum fertilizer dryer speed (shortening the dwell time). When the moisture content is high, adjust the opposite direction. This ensures that every unit of energy consumed is used for effective dehydration, avoiding the waste of high energy consumption processing low-moisture materials.

3. Preventive Replacement of Wear Parts

Worn drum seals (such as the seals at the feed and discharge ports) can cause cold air to infiltrate and hot air to leak, increasing the heating load. Check the seals monthly and replace any signs of aging or deformation. Also, regularly inspect the lift plate. If loose or worn, tighten or replace it promptly. Simple preventive maintenance can significantly reduce future failures and energy costs.
