The Introduction Of Double Roller Press Granulator
Working principle: adopts the design solution of extrusion sliding model,the raw materials pass through double roller,after that,enter into scattering room, come out as granulation, a sieving was mounted at the bottom of the machine, which is customized according to client’s requirement, last, sieve out the granules which is qualified, the rest of materials return to mixer and be re-granulated.

Potassic fertilizers : potassium sulfate, potassium chloride,plant ash etc.
Nitrogen fertilizers : ammonium chloride, ammonium sulfate, ammonium sulphate etc.
Phosphate fertilizer : superphosphate, triple superphosphate, calcium magnesium phosphate

Unit crushed strength : 10-25N
Shape of finished products : oval, irregular, wheat shaped, etc., can also be customized according to customer requirements.
Material moisture requirement : not more than 10%
The rate of ball formation : 95%
Output : 1-4t/h ( can combine multiple granulators work together to increase output, see below
technical process chart).
Granule size : 3-8mm (popular market granule diameter: 2.8-4mm)


1.Double shaft power output, each shaft through coupling to drive its roller to do synchronous work in opposite direction, granule forming is better and the strength is higher.
2.The design of contraposition adjustment of ball socket is simple and convenient for the client to adjust by themselves. Provide the drawing of roller adjustment and operation steps.
3. All machines before leave the factory, had carried out the test and trial production by professional workers.

The roller was first forged and processed from special materials into roughcast, and then machined by numerical lathe and milling machine to be finished product.
The roller with the features of rusty resistance, acid and alkali resistance, long service life, not easy to crack .

Working flow: input ( If blocked, use chain crusher to deal with ) ---- granulation - screening (select the right sieving hole diameter)----finished granules---- the next process (optional equipment: 1, screening machine: the size of the granules will be more accurate. 2, coating machine: make the appearance of the granules more good. 3, weighing and package: facilitate the sale and transportation of products.

Cheng Xiang Heavy Industry founded in 1995, located in xingyang industrial park, Zhengshang new district, zhengzhou city.
