Compound Fertilizer Raw Material for Double Roller Press Ball Machine
Ammonium bicarbonate, ammonium chloride, ammonium sulfate, ammonium sulfate, urea, diammonium phosphate, ammonium nitrate, magnesium sulfate, magnesium silicate, zinc sulfate, phosphorus pentoxide, etc.
Production Moisture of Double Roller Press Ball Machine
When compound fertilizer is produced by roller extrusion granulator, the moisture content of material is very low. However, absolutely dry raw materials are not ideal conditions for compound fertilizer production. In the production process of double roller extrusion granulator, a small amount of water is more favorable for the formation of granules. If compound fertilizer is processed into absolutely dry granules, the processing cost will be greatly increased. Double roller press granulator has different optimum water content range for different materials. For the production of compound fertilizer, the water content of roller press is about 2% - 5%.
Adhesive for Compound Fertilizer Extrusion Granulation
Adhesive is an important factor affecting the production of compound fertilizer by roller press granulator. For compound fertilizer granulation, the extrusion process can only be completed by adding binder in the raw material. In the fertilizer industry, urea and potassium chloride are widely used as binders because of their good plasticity.
Raw Material Characteristics of Double Roller Press Ball Machine
The brittleness and plasticity of compound fertilizer raw materials affect the granulation effect of materials. The size and shape of compound fertilizer particles affect the bulk density of materials. In order to make the compound fertilizer particles have a suitable packing density, the raw materials of the roller press granulator have an ideal particle size range. The granularity of the raw material of the roller press ball granulator is best less than 0. 5 mm, so the effect of compound fertilizer granulation is good.
