The hydraulic double-roller extrusion granulator is an advanced model of the double-roller extrusion granulator. It has the characteristics of great operational flexibility, wide application range, and adjustable extrusion force. This granulator is suitable for granulating various raw materials such as inorganic fertilizers, organic fertilizers, chemicals, feeds, coal, and metallurgy.
The working principle of the hydraulic double-roller extrusion granulator: two counter-rotating rollers squeeze the material, and the hydraulic system adjusts the pressure. When extruding solid materials, the air between the powder particles should first be removed to rearrange them. particles, thereby eliminating gaps between materials. The extrusion function of this granulator is to expel the air between the particles and bring the particles close enough to create van der Waals forces, adsorption forces, crystal bridges and embedded connections. Extrusion granulation mainly relies on the particle strength formed by intermolecular forces.
Hydraulic roller extrusion granulator has the following advantages:
1. Through the hydraulic adjustment system, it can meet the larger extrusion particle molding load requirements, thereby realizing the extrusion of higher hardness particles by two pressure rollers.
2. The hydraulic double-roller extrusion granulator also adjusts the pressure of the hydraulic cylinder to reduce the wear of the granulator rollers caused by high-hardness large impurities in the material, thereby extending the service life of the rollers.
