The double roller granulator uses the way of forced extrusion to make particles, the whole process does not need drying and cooling, and the equipment investment is small. What’s more important is that this granulation method is a very environmentally friendly production mode because it is made of particles by physical methods, and the whole process has no pollution and no waste.
Environmental protection granulation process of double roller granulator
When the double roller extrusion granulator works, it is forced to roll the material into shape by two opposite moving roller skins of the granulator. Semi circular spherical cavities are regularly distributed on the two cylindrical roller skins. When the roller skin rotates against each other, the two semicircular cavities just form a complete spherical mold, and the materials inside are forced to be extruded into spherical particles. Due to the continuity of extrusion production of organic fertilizer granulation machine, the particles and particles are connected together when they are just extruded, forming a cloth full of particles, which needs to be broken up by the crushing roller and divided into small round particles, and then screened from the screen to select the qualified particles.
The fertilizer granulation machine has the advantages of low investment and good economic benefit. The complete set of equipment is compact in layout, scientific and reasonable, and advanced in technology. Energy saving and consumption reduction, no three wastes discharge, stable operation, reliable operation and convenient maintenance. It is suitable for granulation of various raw materials such as compound fertilizer, medicine, chemical industry, feed and so on.
