NPK Dry Chemical Powder Compound Fertilizer Granulator With Double Roller

NPK Dry Chemical Powder Compound Fertilizer Granulator With Double Roller

Introduction of compound fertilizer granulator

Compound fertilizer granulator adopt the new technology of double roll granulation. The equipment investment of the double roller compound fertilizer granulator is reduced by more than 30%. there is no loss of material and physical properties in the production process. the new technology of roller granulation with the mechanical properties of the equipment. The double roller granulator has successfully developed and put into the market Field. At present, the new generation of roller granulation technology, compound fertilizer granulator machine is the equipment investment, high cost defects. Therefore, he has been engaged in chemical fertilizer equipment production process for many years to complete the new technology of compound fertilizer granulation; the drum granulator is a defect of low mechanical performance, large investment and high cost.
For this reason, the investment in chemical fertilizer equipment has been reduced by more than 30% for many years; the granulator for the production of granular compound fertilizer has been developed by our factory a few days ago.

Working principle of compound fertilizer granulator

The type of double roller compound fertilizer granulator working principle is continuously extruding granulation of positive-displacement. The plant can be adapted widely, and the end products possess higher intensity and uniform length. The shape of particle is circular. The diameter of particle is generally from 3.5 mm to10mm.The rate of end products is above 85%. As the material is extruded by means of rolling of gears and positive-displacement compressing, roller extruding granulator possess a wider adaptability to varying material, and is especially suited for granulation with thixotropy. The Scraping cutter installed inside made the particle have the same length. Wetness required for granulation is lower and the particle granulated by this plant is more intensive than screw type granulator.

Advantages of compound fertilizer granulator
1.Reasonable structure. This roller compound fertilizer granulator machine is compact in design, light in weight, steady in rotation, with higher precision and stiffness. The press rollers, which are accommodated to press different shapes/sizes materials, adopt new metal which is resistant to corrosion, oxidation, and abrasion. The double roller press machine is also with perfect performance, reliable operation, easy in maintenance and long service life.
2.Wide application scope. At present, there are 20 kinds of raw materials being applied in this extrusion granulation, such as urea, ammonium nitrate, potassium chloride, bentonite, chicken manure, pig manure, and other animal poultry manure waste etc. In addition, it can replace the product formula flexibly in a short time by adopting extrusion granulation technology. A set of device can produce over 30 product formulas.
3. Making raw materials to fertilizer granules at once time. The roller compound fertilizer granulator has higher granulating ratio of over 85%. The granular shape of finished products pressed by double roller granulator is elliptical.
4. Environmental friendly. Reliable motor is used, no three wastes releasing which is environmental protection.
5. Lower energy consumption. There is no drying process. It doesn’t need oil or gas fired, bringing fertilizer investors good economic returns with low investment.
