The double roller granulator has wide adaptability to raw materials, and is suitable for granulation of compound fertilizer, snow melting agent, ammonium chloride, ammonium sulfate and other raw materials, with high granulation rate. It can produce various concentrations and types of compound fertilizers. In particular, the granulation of rare earth, potassium fertilizer and ammonium bicarbonate series compound fertilizer has filled in the domestic blank, and the granulation equipment of Zhengzhou Huaqiang Heavy Industry Co., Ltd. ranks at the leading level in China. At present, more than 20 kinds of materials have been successfully used in extrusion granulation: ammonium sulfate, ammonium chloride, potassium chloride, potassium sulfate, etc. In addition, the extrusion granulation process can flexibly change the product formula in a very short time, and a set of device can produce more than 30 formula products. The investment of ammonium chloride extrusion granulator is low, because the drying process is omitted, and the return material ratio is low (accounting for about 15% of the total feed amount of the extruder), the process is simple and the investment of the fertilizer granulation machine is low.
