Hydraulic Roller Granulator has wide raw material adaptability and high granulation rate. Can produce various concentrations and types of organic fertilizer, compound fertilizer, inorganic fertilizer, biological fertilizer, magnetic fertilizer, etc. Especially the rare earth, potassium carbonate and ammonium bicarbonate series fertilizers have good particle processing effect.
1. It uses the process that has no drying , and granulating at room temperature, forming at once, it also has the less investment, quick results and good economic returns.
2. It uses the small power and reliable operation, there has no waste discharge, stable operation, convenient maintenance, reasonable layout, advanced technology and low production cost.
3. It has wide adaptability and can be used in the granulation of compound fertilizer, medicine, chemical industry, feed, coal, metallurgy and other raw materials, and can produce a variety of mixed fertilizers, such as organic manure, inorganic fertilizer, bio fertilizer, Magnetized Fertilizer and so on.
Extrusion: Dry materials become cake-like under the twin-roll extrusion of the roller press granulator. At this time, the density of the materials is very high, and the intermolecular voids are very small. It is not easy for the dry materials to enter the air and get damp in the later storage of the finished products. In this process, the principle of intermolecular force in physics is also used to combine extruded molecules freely into molecules with appropriate spatial density.
Granulation: The material which is pressed into a cake shape is broken down by the double roller press granulator and is divided into numerous small particles to achieve the purpose of granulation.
