Granulation technology of ammonium chloride extrusion fertilizer pellet machine


The granulation principle of the extrusion fertilizer pellet machine is that the material sent by the conveyor driven by the motor is broken by the chopping system, and then the powder material is evenly added into the binding piece for shaking, and then it enters the roller mouth after forced degassing and pre pressing. According to the requirements of the granule specifications, with the rotation of the roller, it gradually reaches the molding. Then the automatic demoulding process is completed.

Granulation technology of ammonium chloride extrusion fertilizer pellet machine
No drying and normal temperature production process is adopted in the extruding fertilizer pellet machine. There is no need to add adhesive, the investment is low, and the composition of raw materials is flexible. The raw material route of compound fertilizer production by extrusion granulation is wide and one-time molding. The equipment has the advantages of less investment and quick economic benefit.

The whole set of fertilizer granulation process has compact layout, scientific and reasonable, and advanced technology. Energy saving, no waste discharge, stable operation, reliable operation and convenient maintenance.

At present, there are more than 20 kinds of materials successfully used in extrusion fertilizer pellet machine: 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 (about 15% of the total feed volume of the extruder).
