Extrusion Granulator Machine , Granules Fertilizer Production Line
Introduction of NPK Fertilizer Production Line
NPK Compound fertilizer production line is widely applied to produce compound fertilizer and the capacity ranges from 5000-200,000 tons/year. It can granulate NPK, NP, ANP, DAP, MAP, CAN, SSP and other materials into compound fertilizer particles in one processing line.
According to the many years of production experience, the DZJ series roll press granulator is a new type of equipment developed on the basis of the original double roll extrusion granulation.
Working Process Of NPK Compound Fertilizer Making Production Line
It 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.
Raw Material For NPK Compound Fertilizer Making Production Line
1) Agricultural waste: straw, dregs of beans, cotton dregs, rice bran,etc.
2) Animal manure: mixture of poultry litter (PL) and animal waste(AW),such as, Slaughterhouse Waste, F ish Market, Urine and dung of cattle, Pigs, Sheep,C hicken, Ducks, Geese, Goat.etc.
3) Industrial waste: wine lees, vinegar residue, manioc waste, sugar scum, furfural residue etc.
4) Home scrap: food waste, bones, the roots and leaves of vegetables, etc.
5) Sludge: the sludge of the river, the sewer, etc.

Features of NPK Fertilizer Production Line
1. roller material : Stainless steel wear-resisting material
2. maintenance convenience
3. into ball in a one process,into ball rate more than 85-95%
4. raw materials' moisture : 5%-10%
5. 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.
6. 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.
7. All machines before leave the factory, had carried out the test and trial production by professional workers.
