The double roller fertilizer granulator is a newly developed granulator in the fertilizer industry. This equipment can form fertilizer particles with a diameter of 1-4mm at one time, and the granulation rate is as high as 85%, which can bring good economic benefits to fertilizer investment.

The granulation process of  double roller fertilizer granulator is divided into two parts: extrusion process and granulation process.
The dried material is compressed into a hard and dense block under pressure, which is the extrusion process. The function of pressure is to squeeze the air between the particles so that the distance between the particles is close enough to generate an interaction force.The block material is crushed, sieved and granulated, which is the granulation process.
