The role of fertilizer granulator in compound fertilizer production line

fertilizer granulator Apr 10, 2024

Building an npk production line requires a compound fertilizer granulator. There are many compound fertilizer processing and granulating equipment. Some companies are not clear how to choose a suitable compound fertilizer granulator. What are the compound fertilizer granulating equipment introduced today? There are three main types of compound fertilizer granulators: rotary drum granulator, disc granulator machine and double roller granulator. What is the difference between these compound fertilizer granulators? What are the advantages and disadvantages of each?

The disc granulator machine mainly uses the rolling of the disc surface and the granulation of the granules themselves, and is used in conjunction with the upper mixer to achieve a high ball forming rate. The investment cost of granulator equipment is low, and the production capacity is strong, but the dust of open-air granulation is relatively large.

The barrel of the rotary drum granulator equipment is lined with a special rubber plate or an acid-resistant stainless steel liner to realize automatic scar removal and tumor removal, and the traditional scraper device is eliminated. A drum granulator is a forming machine that can shape materials into specific shapes. The main working method is granule wet granulation. With a certain amount of water or steam, the basic fertilizer can fully react after being humidified in the cylinder. Under certain liquid phase conditions, with the help of the rotary motion of the cylinder, the extrusion force between the material particles is agglomerated into balls. The investment cost of fertilizer equipment is high, the production capacity is strong, and the dust of drum granulation is relatively small.

The double roller granulator is produced by a non-drying normal temperature process, and it is formed at one time. The equipment has low investment, quick effect and good economic benefit. The complete set of equipment is compact in layout, scientific and reasonable, and advanced in technology. Energy saving and consumption reduction, no waste discharge, stable operation, reliable operation and convenient maintenance. Wide adaptability of raw materials, suitable for granulation of raw materials such as compound fertilizer, medicine, chemical industry, feed, etc., and the product granulation rate is high. Various concentrations and types of compound fertilizers (including organic fertilizers, inorganic fertilizers, biological fertilizers, magnetic fertilizers, etc.) can be produced.

The difference in granulation between roller extrusion granulator and drum granulator

The double roller granulator is a kind of granulation equipment with wide adaptability to raw materials. The double roller granulator is the key equipment for the granulation of the npk production line, and it can also be used for the production of organic fertilizers. Our twin roll granulator adopts dry granulation method. You can make granular fertilizers at room temperature without drying. You can use it to form an efficient fertilizer production line with our other fertilizer equipment.

Both double roller granulator and rotary drum granulator are granulation equipment. It is suitable for the production of high, medium and low concentration compound fertilizers. However, there are some differences between the double roller granulator and the drum granulator.

1. Different granulation methods.

The double roller granulator adopts the dry granulation method, while the rotary drum granulator is a wet granulator. This means that you don’t need to use other equipment to dry the product after granulating with the double roller fertilizer granulator. The granulator consumes less power and produces no pollution. In addition, it requires the moisture content of the raw material to be only 5%-10%. And relatively dry fertilizer granules can be obtained at normal temperature. But if you use a rotary granulator to make fertilizer granules, you need a drying cooler to dry them. You can save some money if you buy our granulator to produce compound fertilizer.

2. The working principle is different.

The structural design of the double roller granulator and the rotary drum granulator are different, so their working principles are also different. The rotary granulator uses the rotating motion of the drum to agglomerate the material particles into balls. The double-roller granulator uses mechanical pressure to process powdery materials into fertilizers of different shapes.

3. The shape of fertilizer particles can be different.

A rotary drum granulator can form the product into a roughly spherical shape. But the double roller granulator can produce fertilizer products in various shapes, such as pillow shape, rod shape, pellet shape, walnut shape, and square bar shape.

Equipment required for the organic fertilizer production line of chicken manure, cow manure

fertilizer granulator Apr 7, 2024

Using chicken manure, cow manure, and mushroom residue as raw materials, processed into organic fertilizer through a powder organic fertilizer production line, is currently a commonly used process. Due to its simple process, less equipment required, less investment, and fast cost recovery, many customers want to purchase a fertilizer production line. The customer’s main concern is the income of organic fertilizer and the equipment required for the powder organic fertilizer production line. The main equipment for the powder organic fertilizer production line is the organic fertilizer turner, horizontal mixer, and high humidity material crusher. 

Equipment required for the organic fertilizer production line of chicken manure, cow manure, mushroom residue, and mushroom residue: flipping machine (used for composting process) – vertical crusher (crushing larger blocks in organic fertilizer) – screening machine (screening out non compliant organic fertilizer and returning it) – batching machine (adding other required nutrients to organic fertilizer according to a certain proportion, which is an optional device) – horizontal mixer (mixing different materials evenly and using it in combination with batching machine) – single bucket packaging machine (used for quantitative packaging of finished organic fertilizer)

Selection of equipment for organic fertilizer production line of chicken manure, cow manure, mushroom residue, and mushroom residue

Organic fertilizer stacker, currently there are mainly two types of composting stackers: strip stacker and trough stacker. Mobile stacker is mainly suitable for areas with relatively small production and large sites. Mobile stacker is generally suitable for strip stacker composting, while trough stacker is generally suitable for establishing fermentation tanks and used in conjunction with fermentation tanks. In general, flipping is necessary during fermentation, with the aim of providing sufficient oxygen to microorganisms during aerobic fermentation of organic materials, controlling fermentation temperature, and releasing moisture.

Organic fertilizer mixers generally choose horizontal mixers because nitrogen, phosphorus, and potassium need to be added during the mixing process. The country requires nitrogen, phosphorus, and potassium content to be greater than 5%. The key to choosing a horizontal mixer is to clarify your purpose and purpose, understand the power configuration and raw material supply of the horizontal mixer.

In the organic fertilizer production line of chicken manure, cow manure, mushroom residue, and mushroom residue, due to the need to crush the materials after fermentation, a crusher is needed. This machine has the same crushing effect on fermented organic fertilizer, sludge, biogas residue, coal gangue and other slag. The production capacity of the high humidity material crusher is 1-4 tons, and the feed moisture content is ≤ 40%. The power configuration and raw material moisture content of the production capacity meet the requirements of the powder organic fertilizer production line. Therefore, it is very suitable to match the high humidity material crusher with the powder organic fertilizer production line.

Differences in supporting equipment for processing and producing organic fertilizers and compound fertilizers

fertilizer granulator Apr 7, 2024

Organic fertilizer and compound fertilizer are different, and the supporting equipment for processing and producing organic fertilizer and compound fertilizer are also different. From a professional perspective, compound fertilizer equipment is mainly used for producing chemically synthesized compound fertilizers, also known as compound fertilizers. Compound fertilizer is a compound fertilizer made by chemically or physically mixing multiple nutrients.

Compound fertilizer, also known as compound fertilizer, contains at least two of the three nutrients of nitrogen, phosphorus, and potassium. It is a fertilizer made by chemical methods. The advantage is that it contains more nutrients, fewer side components, and has good physical properties, which is conducive to balancing fertilization rates and promoting crop yield. However, the disadvantage is that the proportion of nutrients in compound fertilizers is fixed, which cannot meet the nutritional needs of different soils and crops.

Compound fertilizer equipment usually includes equipment such as crushers, mixers, granulators, screening machines, packaging machines, etc. It mainly mixes multiple fertilizers through mechanical and chemical methods to form compound fertilizers with multiple nutritional elements.

Organic fertilizer is a fertilizer processed from poultry and livestock manure, plant residues, and waste, and is the main fertilizer used in the production of green food. Fertility and nutrition are long-lasting and comprehensive, which can improve and renew the organic matter in the soil. On the other hand, it can promote microbial reproduction, increase soil physicochemical properties and activity.

Organic fertilizer equipment is mainly used for the production of organic fertilizers, also known as organic fertilizers. Organic fertilizer is a fertilizer made from organic matter through methods such as microbial decomposition and composting. Organic fertilizer equipment usually includes turners, crushers, impurity removal machines, fermentation devices, batching machines, packaging machines, etc. It mainly decomposes organic matter through the action of microorganisms to form organic fertilizers with rich organic matter and trace elements.

How to solve the problems that occur during the granulation process of the disc granulator?

fertilizer granulator Apr 7, 2024

Common organic fertilizer granulators include: double roller granulator, rotary drum granulator, disc granulator machine, new organic fertilizer granulator machine, new two-in-one organic fertilizer granulator, flat die granulator machine, ring die granulator, and various granulators have their own production characteristics. The disc granulator machine can be used in both the organic fertilizer production line and the npk production line. Today, let’s learn how to solve the problems of the disc granulator during use?

Fault 1: Strong vibration of the body of the disc granulator machine?

Solution: Fix the base of the granulator firmly, and check whether the gears of the fuselage are meshed normally (some organic fertilizer equipment manufacturers leave “tire belt” faults during the production process).

Fault 2: Intermittent operation.

Solution: This kind of failure is generally caused by bearing damage, disc weight loss, abnormal motor voltage and other reasons. The operation failure of the disc granulator can be quickly eliminated through wire drawing and timely maintenance.

Fault 3: How to adjust the disc tilt too much?

Solution: When the disc granulator machine is in use, there are no specific parameters for your reference, but it should be based on the formation of suitable spherical particles. The adjustment measures are to adjust the bolts at the bottom of the disc, and change the position and viewing angle of the reducer to achieve normal use.

Fault 4: The material is difficult to form

Solution: In addition to the subjective factors of raw material composition, the granulation of the disc granulator also has an important relationship with the particle size of the raw material, water content, addition of auxiliary binders, and the angle of the disc operation. These problems should be constantly tried to achieve the appropriate ratio according to their own material conditions, and make improvements to achieve our expected value.

Fault 5: uneven particles

Solution: The treatment of this type of problem is divided into two parts. Improve moisture content and control the size of shaped particles. Then, through post-drying screening and selection, our selection narrows down.
