Granulators for Compound Fertilizer

The rotary drum granulator is one of the key equipment for compound fertilizer production. It is suitable for cold and hot granulation and large-scale production of high, medium and low-concentration compound fertilizers. This machine has the characteristics of beautiful appearance, low energy consumption, long life, simple operation, uniform drying and convenient maintenance. It is a relatively advanced granulation equipment.

The working principle of the rotary drum granulator:

The rotary drum granulator adopts agglomerate wet granulation, through a certain amount of water or steam, the basic fertilizer is fully chemically reacted in the cylinder after the humidity is adjusted. Under a certain liquid phase condition, with the help of the Rotating movement causes the squeezing force between the material particles to reunite into balls.

Advantages of the rotary drum granulator:

1. High wear resistance and corrosion resistance. The main body is made of high-quality carbon steel, which has better wear resistance and corrosion resistance.

2. The raw material does not stick to the wall. The rubber engineering plastic is used as the inner lining, no scraper device is needed, the raw material is not easy to stick to the cylinder, and it has the effect of anti-corrosion and heat preservation.

3. Easy to dry. Steam heating is used to increase the temperature of the material, so that the water content of the material is low after the ball is formed, and the drying efficiency is improved.

4. Low cost. It consumes less energy while ensuring output, which greatly reduces costs.

Maintenance of the rotary drum granulator:

1. The shaft bears the full load of the negative machine, so good lubrication has a great influence on the life of the bearing. It directly affects the service life and operation rate of the machine, so the lubricating oil must be clean and the seal must be good. The main oil filling point of this machine

(1) Rotating bearing

(2) Roll bearing

(3) All gears

(4) Movable bearing, sliding plane  

2. The newly installed wheel tyres are prone to loosening and must be checked frequently.  

3. If the rotating gear is running, if there is an impact sound, stop and check it immediately and eliminate it.

4. Pay attention to whether all parts of the machine work normally.  

5. Pay attention to check the degree of wear of easily worn parts, and pay attention to replacing worn parts at any time.  

6. If the bearing oil temperature rises, stop the machine immediately and check the cause to eliminate it.  

7. On the plane of the bottom frame of the movable device, dust and other objects should be removed to prevent the movable bearing from moving on the bottom frame when the machine encounters unbreakable materials, which may cause serious accidents.
