cement roller press of pre-grinding system
Working principle of roller press:
Roller press is composed of two extrude roller rotating in reverse direction, one is fixed roller and the other is moveable roller. Material will be fed from the above of two rollers, be brought into by extrude roller, then it will be discharged in material cakes under the machine after being pressed by 50-150MPa strength. Discharged material cakes will include some finished fine particle, besides lots of half-finished particles with cracks will be produced which will reduce energy consumption during following crushing process.
Characters of roller mill:
1) Erect roller press into grinding system which could improve the capacity as 30%-40% meanwhile total power consumption will reduce as 20%-30%.
2) Roller press with tight structure and small volume could obviously reduce the investment for grinding system
3) Roller press with simple structure, small space and easy operation and maintenance.
4) Compared with other grinding equipments, roller press with less powder and lower noise which largely improve the working condition.
