Fertilizer granulation equipment

Fertilizer is an indispensable part of agricultural production, and the utilization rate and effect of fertilizer are one of the key factors in agricultural production. Fertilizer granulation equipment is an important means to improve the utilization rate and effect of fertilizers. At present, common Fertilizer granulation equipment includes Disc granulation equipment, Double roller granulation equipment, Rotary Drum granulation equipment, New type organic fertilizer granulation equipment, etc.

Disc granulation equipment

Disc granulation equipment is an ancient fertilizer granulation equipment. Its working principle is to use the rotation of the disc to throw up the material and make it subject to gravity to form spherical or elliptical particles. Disc granulation equipment has the characteristics of simple structure and low cost, and is suitable for the production of fertilizer products with small particle diameters, such as organic fertilizers and biological fertilizers. However, the efficiency of Disc granulation equipment is low, and the compactness and hardness of the particles are relatively low.

 

Disc granulation equipmentProcess

  1. Raw material preparation: The organic fertilizer raw materials (such as livestock and poultry manure, straw, mushroom slag, etc.) are pretreated by crushing, sieving, drying, etc., so as to make them suitable for processing by Disc granulation equipment.
  2. Granulation: Put the processed raw materials into the Disc granulation equipment, and extrude the materials through the gap between the rotating disc and the fixed template to form granules. During this process, the parameters of the granulation equipment, such as flow rate, pressure, etc., can be adjusted as needed to obtain different particle sizes and shapes.
  3. Cooling and sieving: The granules generated after granulation need to be cooled and sieved in order to obtain qualified products. In general, cooling can be realized by natural cooling or cold air cooling, and screening can be carried out by means of a vibrating sieve or air flow sieve.
  4. Packaging: Qualified products need to be packaged for storage and sale. Packaging can be carried out in plastic bags, woven bags, etc., determined according to market demand.

Double roller granulation equipment

A double roller granulator is a device that uses pressure to granulate materials. Its working principle is to use a pair of rotating rollers to flatten and stretch materials, and then knead them into spherical or oval particles. Double roller granulation equipment has the characteristics of high efficiency and high particle hardness, and is suitable for the production of fertilizer products with large particle diameters, such as inorganic fertilizers and chemical fertilizers.

Double roller granulation equipment process

  1. Raw material preparation: Pretreatment of feed materials such as crushing, screening, drying, etc., so as to make them suitable for processing by Double roller Double roller granulation equipment.
  2. Granulation: Put the processed raw materials into the Double roller granulation equipment, and extrude the materials through the extrusion and friction of the rollers to form granules. In this process, parameters such as the rotating speed and pressure of the counter-roll can be adjusted as needed to obtain different particle sizes and shapes.

Rotary Drum granulation equipment

The spinning granulator is a kind of equipment that uses the rotating rotor to granulate the material. Its working principle is to use the rotation of the rotor to throw the material up and then drop it down to form spherical or elliptical particles. Share-swapping granulation equipment has the characteristics of high efficiency and high particle hardness, and is suitable for the production of fertilizer products with large particle diameters, such as inorganic fertilizers and chemical fertilizers. However, the cost of stock transfer granulation equipment is high, the operation is complicated, and a high level of technical operation is required.

New type organic fertilizer granulation equipment

New type organic fertilizer granulator is a device that uses stirring teeth to granulate materials. Its working principle is to use the rotation of stirring teeth to tear and stretch the material, and then knead it into spherical or oval particles.
