The ball grinder is a kind of equipment to grind ores and other materials with powder to obtain desirable granularity of products. The ball grinder designed and manufactured by our company has been widely applied in such industries as metallurgy, mining, building materials and chemical industry home and abroad.

The ball grinder is mainly composed of feeding, charging, main bearing, barrel, transmission, discharging parts and main motor. The barrel of grinder is driven by the motor through transmission and deceleration of gear pair to rotate in appropriate rotary speed. The medium for ore grinding is lifted to a definite height under the action of centrifugal force, friction and gravity and then drop down in throwing up or falling state. The materials within barrel are crushed under impact of medium. 

Meanwhile, the materials are ground under grinding stripping action due to rolling or sliding of medium. The materials are discharged through discharge hole after being ground. The grinder may be provided with air clutch, slow driving/jacking/jet lubrication devices as required. The ordinary sliding bearing, dynamic/static pressure bearing, hydrostatic bearing and rolling bearing may be adopted for main bearing of grinder as required.

The rolling bearing can be adopted for main bearing of ball grinder below Φ6200 (includingΦ6200) series manufactured by our company, which is characterized by simple structure, high efficiency as well as easy installation and maintenance.

The magnetic lining plate may be adopted for ball grinder as required, which is thinner compared with the metal one, lighter in weight and longer in life. It can reduce the energy consumption while improving output and is applicable for two-section grinder generally. Our company is able to design and manufacture the grinder with various specifications for multiple uses based on customer demands.
