The fertilizer granule machine is a kind of extrusion granulator, which consists of a feeding device and two parallel rollers. There is a small gap between the two rollers. The gap between the rollers is adjusted by the push rod of the hydraulic cylinder. The constant extrusion force of the granulator can be maintained by adjusting the clearance, thus ensuring the granulating effect.

1. Material can be formed by forced compression under mechanical pressure without any additives, and the purity of the product can be guaranteed.
2. Dry powder enters the machine directly for granulation, and the granular products do not need the follow-up drying process, which is more conducive to the processing of the existing production process.
3. Particle strength is high, and the increase of accumulation ratio is more significant than other granulation methods. It is especially suitable for the occasion of increasing the proportion of product accumulation.
4. Reduce environmental pollution, reduce waste of principle powder and packaging cost, and improve product transport capacity.
5. Roller granulation production process is short, low energy consumption, high efficiency, and suitable for a wide range of raw materials. Roller pressure can be adjusted freely according to different materials.

Applicable Materials
1. Fertilizer: compound fertilizer, potassium fertilizer, potassium sulfate, potassium chloride, red potassium, NPK compound fertilizer, ammonium chloride, potassium nitrate, monoammonium phosphate, diammonium phosphate, ammonium sulfate, ammonium bicarbonate.
2. Powder materials: antioxidant, bromochlorohydantoin, sodium dichloroisocyanurate, sodium trichloroisocyanurate, cyanuric acid, bleaching powder, zinc oxide, lead oxide, potassium carbonate, strontium carbonate, calcium chloride, calcium hydrogen phosphate, sodium metasilicate, sodium orthosilicate, cryolite, aluminium fluoride, brake powder, rubber-plastic additives, white carbon black, calcium aluminate, bicalcium, calcium perfume, phosphatite, metal powder Fine, filler, feed additive, arsenicoline, nicotinic acid, nicotinamide, steelmaking additive, snow melting agent, environmental protection material.

Working Principle
After adding raw materials from the feed port, the roll of the granulator bites the material into the gap of the roll for compression. After the material passes through the compression zone, the surface tension and gravity of the material make it enter the rotary screen for screening. Qualified products are sent to the finished warehouse by conveyor. The material under the powder sieve is sent back to the raw material bin through the conveyor for secondary roll pressing. The extrusion force can be adjusted by the pressure of the hydraulic cylinder according to the operation needs, and finally the granulation quality and output can be improved.
