Drum granulator is a kind of fertilizer granulator machine can make the material into a specific shape. Drum granulator is one of the key equipment of the compound fertilizer industry. It is suitable for large-scale production of cold &hot fertilizer granulation line and high and low concentration compound fertilizer line. Main work method for aggregate wet granulation, through a certain amount of water or steam, the basis for fertilizers in the cylinder body after full wet chemical reaction, in a certain liquid under the conditions of the rotating cylinder with campaign, reunion between particles to produce extrusion pressure of material into a ball.
Drum cylinder adopt special rubber lining or acid stainless steel plate, has realized the automatic except scar, tumor, cancel the traditional scraper device. The machine has the characteristics of high ball strength, good appearance, corrosion resistance, wear resistance, low energy consumption, long service life, easy operation and maintenance.
Drum granulator, machine ventilation with steam, gas, or adding phosphoric acid or ammonia nitrogen and phosphorus ammonia solution slurry, coarse whiting slurry, within the cylinder with the fertilizer granulation process of chemical reaction and heat; Or cold added a small amount of moisture content of compound fertilizer granulation process. The need of granulating material through the rotation movement of the cylinder, the cylinder didn't scroll spin, sticking together under a certain humidity, temperature, into a ball, complete system process.
Drum granulator features:
1, The granulate rate is 70%, there is a small amount of returns, return product particle size small, can be granulated again.
2, Put into the steam heating, improve the material temperature, the material into the ball after the water is low, improve drying efficiency;
3, with rubber engineering plastics for lining, raw materials is not easy to stick, and play a role in anti-corrosion insulation;
4, large output, low power consumption, low maintenance cost.
Drum granulator structure:
1. Bracket part: The drum granulator cylinder is equipped with rollers, which are supported on the bracket support of the front bracket wheel and the bracket group. The whole drum is supported by the bracket, and the force is greater. Therefore, the bracket parts of the machine are welded with medium carbon steel plate and channel steel and adopt special technology. Anti-corrosion and wear-resistant materials are selected for the supporting wheel, which greatly improves the service life of the drum granulator.
2. The transmission part of the drum granulator drives the whole granulator to work. The transmission frame is welded with high-quality channel steel. The main motor and speed reducer installed on the transmission frame are ISO national inspection-free products with reliable quality. The motor drives the belt pulley, triangle belt and reducer to the main shaft to make the body work. The drive reducer is used in the working part of the main shaft.
3. The big gear of the drum granulator is fixed on the body, which is geared with the transmission pinion and drives the body to work in opposite direction. The machine uses high-tech wear-resistant material, which makes the service life of the machine longer.
4. Rolling belt: Fixed to both sides of the body to support the whole body.
5. Body part: The body is the most important part of the drum granulator, which is welded by high quality medium carbon steel plate. In order to prevent the material from bonding in the drum, special rubber lining or acid-resistant stainless steel lining is laid on the inner wall of the drum to remove the material from the drum wall, and the traditional scraper device is cancelled to ensure the normal granulation of the material.

Drum granulator works principle:
This series of drum granulator working principle is: the main motor drive belt and pulley, through the reducer drive to the drive shaft, through the installation of the open shaft on the gear and fixed on the body of the large gear teeth And work together. The material is fed from the feed end through the inside of the cylinder. Through the role of the internal structure of the cylinder, made of particles, and finally out through the outlet. As the material continues to enter, granulator of the continuous rotation, in order to achieve mass production.
