PROCESS
1. The combined classifier improves the powder selection efficiency.
2. It is not necessary to distribute material on the grinding plate before start-up. The roller can be lifted up and down automatically and start without load.
3. It is well sealed by welded arc plate and structure is simple and reliable.
4. With the help of roller turning device, it is easily to turn the roller out for maintenance.
5. Both sides of roller sleeve can be used so that the service life of refractory material is extended.
6. Grinding roller limit device can ensure a certain space between roller and plate, which avoids the direct friction and collision between roller and plate and enhances safety.
7. The grinding roller is driven by liquid -gas pressure. Pressure filling and adjustment and roller lifting can be remotely controlled without operator on-site.
8. The roller bearing is circularly lubricated by thin oil to enable it to work under low temperature and clean grease so that the service life is extended.
