Frequently Asked Questions
1. What power range should I consider for cement grinding applications?
Depending on the size of the mill and the throughput goals, cement grinding operations usually need motors between 500 and 1500 kW. When grinding raw materials, smaller motors of 400 to 800 kW are often used. When grinding finishes, however, higher power levels are needed. Our 400–2000 kW product range covers most industrial grinding needs. The exact size is chosen by calculating the load while taking into account the material's properties and production goals.
2. How does starting torque affect ball mill motor selection?
Due to the static load of the grinding media and material, ball mills need a lot more starting torque than they do running torque. Our motors deliver 220 to 280 percent of their rated torque when they first start up, so you don't need any extra equipment to get them going. This specification is very important for grinding applications because not having enough starting torque leads to long acceleration periods that overheat the windings or fail to reach operating speed.
3. Can bearing types be customized for specific operating conditions?
We can customize bearings from SKF, NSK, or FAG brands, depending on the needs of the application. When bearings are used continuously or with little lubrication, premium grades last longer. Deep groove ball bearings are our standard configuration and work well in most situations. You can upgrade them during the procurement process to get better performance or longer maintenance intervals.
