Fig I Diagram of Ball Mill
As shown in Fig I, the ball mill generally consists of eight parts: feeder, main bearing, feeding unit, cylinder, discharging unit, gear mechanism, gear cover, and foundation.
As per the types of ball mills, they can be classified into overflow type (MQY type) and trellis type (MQG type).
As per driving types of ball mills, they can be classified into dextrorotary type and laevorotatory type.
As per modes of installing ball mills, they can be classified into with base plate type and without base plate type. With regards to ball mill with base plate, except an additional base plate, all the other parts are the same as those of ball mill without base plate. Below 15 series is with base plate.
As per motor modes of ball mills, they can be classified into YR motor and JR motor. The structure difference between two types is the motor, the parts march to the motor and basement. The principle of two type marched is: to adopt YR motor when smaller than 80KW, to adopt JR motor when larger than 80KW.
