double roller granulator, fertilizer roller press granulator

Double roller granulator is multifunctional fertilizer press machine, this fertilizer roller press granulator can make compound fertilizer and organic fertilizer pellets. It is multifunctional, but the finished granules are oval. It can be made into round pellets by shaper, which is developed by our company. The production process only needs room temperature and no dryer, which can save a lot of energy and cost. The production output of double roller press granulator is 0.5-1t/h, 1-1.5t/h and 1.5-2t/h respectively. If you want to use the disc granulator, it is also the best organic fertilizer machine. we have rotary drum granulator to make compound fertilizer as your another choice.

Working principle

The double roller granulator represents an fertilizer extrusion granulator. The dry material is compressed into hard and dense blocks under pressure, which is the extrusion process. The block material is crushed, screened and granulated, which is the granulation process. The effect of extrusion is to squeeze out the air between the particles so that the particles are close enough together to create an interaction force. The particle hardness of crushed pelletized particles is mainly due to the mutual attraction between molecules.

Our double-roller press pelletizer is a positive displacement continuous extrusion pelletizer. This double-roller press granulator has two main working parts.

1.Pressing and squeezing section: the material is pressed into large and dense hard cakes under pressing pressure.

2. Granulating section: The filter cake is crushed and sieved into small particles.

Note: The finished pellets of this double roller granulator are oval, if you need spherical pellets, you can use the spherical shaper, which is used to make cylindrical and oval pellets (pellets) into spherical pellets. It adopts the working principle of high speed rotation to make spherical pellets.
