Double roller granulator is a newly developed granulating machine in fertilizer industry

Double roller granulator is a newly developed granulating machine in fertilizer industry. It uses squeezing principle to form fertilizer particles with diameters of 3.5-10mm in one time.It has higher granulating ratio of over 85%.Double roller fertilizer granulator is the most popular granulating methods in no-drying (2%-5% moisture content) fertilizer process at room temperature.Less cost and quick granulating,thus it can bring fertilizer investment a good economic returns.

Application of Roller Fertilizer Granulation Machine

Fertilizer Industry:potassium sulphate, potassium chloride, urea, NPK compound fertilizer, ammonium chloride, potassium nitrate, monoammonium phosphate, diammonium phosphate, ammonium sulphate, ammonium bicarbonate, magnetic fertilizers etc.Chemical Industry:antioxidant,sodium chloride,cyanuric acid, activated carbon,rock phosphate powder,rare earths,feed additives, green materials etc.This compound fertilizer granulating machine is usually used in compound fertilizer plant.


Double Roller Fertilizer Granulator Structure

♦ Rollet machine rack:all working parts are fixed on machine rack.The rack is made of medium carbon steel plate and channel beam which are welded.In the middle of rack quadrangle there is a lifting hole for loading or unloading transportation.

♦ The transmission and connection part: Motor drives belt pullery, triangle belt,reduction gears and makes machine to work.

♦ Granulating part:Through pin coupling,the driving roller rotates. On both sides of the driving shaft and driven shaft are specially designed bearings and bearing bracket.

♦ Crushing and separating part:Fertilizer materials after squeezing downflow to the crushing room.On the double roller there are many short bars rotating along with rollers which separate fertilizer particles from reverting materials.

Features of Roller Fertilizer Making Machine


1.the fertilizer making machine has no drying process,normal temperature granulating,one-step forming.

2.Saving energy and cost,no waste water or gas emission.

3.the fertilizer granulation machine has compact structure,easy and stable operation,easy maintenance.

4.Press rollers adopt new metal which is resistant to corrosion, wear and impact.

5.The press rollers can be designed to make different shapes and sizes of materials.
