Organic fertilizer dry roller granulator

Organic fertilizer dry roller granulator

Dry roller granulator is also called dry powder granulator, which is often used for shaping pressing of dry powder raw materials. It is also called organic fertilizer dry roller granulator when used for pressing powder organic fertilizer. It adopts dry roller technology, the dry powder materials

whose water content is less than or equal to 10% are made into special equipment of granular products by external pressure.

All kinds of dry powder materials are added from the feeding port of the equipment, after degassing and screw prepressing, they enter the opposite roller, under the action of the great compression pressure of the opposite roller, the materials are plastic deformed and compressed into flaky and flaky materials. After the process of crushing, forming and screening, the particle-like products are obtained.

Working Principle of dry roller granulator:

Organic fertilizer dry roller pelletizer is driven by electric motor with Belt and belt wheel, which is transmitted to the driving shaft through speed reducer, and synchronizes with the passive shaft through the counteropen gear, and works in the opposite direction. All kinds of dry powder materials are added from the feeding Hopper on the top of the equipment, and enter into two equal rollers through degassing and spiral prepressing. The rollers rotate relatively, and the materials are forced to be sent between the two rollers, the roller bites the material into the gap of the roller to conduct forced compression. After the material passes through the compression zone, the surface tension and gravity of the material make it escape naturally.

Through roller extrusion molding, demoulding ball making, and through a pair of chain, it is delivered to the crushing sieve studio, sifting and separating finished (ball) particles, and then returning material and mixing new material, then conduct pelleting. With the continuous rotation of the motor and the continuous entry of materials, mass production can be realized.

After being taken out, the finger-shaped lumps enter the granulator and are broken by rotating knife. The broken materials enter the granulator and make the particles and part of the powdered materials enter the rotary sieve for screening through rolling knife, qualified products are sent to the finished warehouse through the conveyor. The materials under the powder screen are sent back to the raw material warehouse for secondary roller pressing through the conveyor, and the size of the extrusion pressure can be adjusted by the hydraulic system according to the need of the pelletizing operation. By changing the groove form of the roller surface, materials like flaky, strip and flat ball can be obtained.

Dry roller granulator features:

1. Adapt to a wide range of raw materials, particle strength can be adjusted freely according to different materials;

2. Without any additives, dry powder is directly granulated;

3. It can control environmental pollution, reduce powder waste and packaging cost, and improve product transportation capacity;

4. Circular operation to realize continuous production and high output of finished products;

5. The feeding and feeding devices adopt variable frequency stepless adjustment control, which has high degree of automation and can realize the control of one person and multiple machines, and has the characteristics of low labor intensity and long-term continuous operation;

6. The particle strength can be adjusted, and the strength of finished products can be controlled by adjusting the pressure of the roller;

7. Direct pelleting of dry powder, without subsequent drying process, is more conducive to the connection and transformation of the existing production process;

8. The materials are forced compression molding by mechanical pressure without any additives, and the purity of the products is guaranteed;

9. The main transmission parts all adopt high quality alloy materials. The manufacture of stainless steel materials, titanium materials, chromium and other surface alloy greatly improves the ability of abrasion resistance, corrosion resistance, high temperature resistance and pressure resistance, which makes the machine have a longer service life;

10. The particle strength is high, and the increase of accumulation proportion is more significant than other ways of pelleting, which is especially suitable for the occasion of increasing the accumulation proportion of products;

11. Compact structure, convenient maintenance, simple operation, short technological process, low energy consumption, high efficiency and low failure rate.

Application of dry roller granulator:

1. Organic fertilizer dry roller granulator is mainly used for particle processing of (biological) organic fertilizer and processing industry of breeding industry.

2. The surface of the particle material processed by the machine is bright and clean, and its hardness is moderate. During the process of processing, the temperature rise is low and various nutrients inside the raw material can be well maintained.

3. Because the moisture content of particles is low and easy to store, the utilization rate of materials is greatly improved
