Application of organic fertilizer granules in double roller granulator

What is a Double roller granulator?

• Double roller granulator, is dry granulation equipment that can quickly extrude and separate materials at room temperature and processes them into oblate particles. Compared with other granulation equipment, no drying measures are required, which simplifies the granulation process. The return rate is very low, no need to add adhesives. The double roller granulator is widely used in granule processing in pharmaceutical, food, chemical, and other industries, with small investment and high production efficiency. Combined with other related equipment, it can form an automatic organic fertilizer granule production line.

Advantages of double roller granulator:

• Particles are formed at one time, no need to add a binder
• Granulation at room temperature without drying process
• By adjusting the double roller pressure and size, the particle size and hardness can be changed
• Small footprint, low energy consumption, good anti-corrosion effect

​Working Process of Double Roller Granulator Fertilizer Making Machine

The Materials entering the double roller granulator enters through the upper conical material opening, and the air between the material molecules is expelled by the action of pressure. Rely on the force between molecules to form a high-hardness ball cake, and then fall into the lower part of the sawtooth crumbs. The ball cake particles are separated by crushing; and then enter the screen, and the qualified particles flow out from the bottom outlet.
