Large Electromotor Ball Mill Drive System

Assessment of the drive system of a large ball mill from the pOint of view of energy economy leads to the coaxial drive layout. Dependability and maintenance costs are further decisive criteria. The high standards of engineer-ing attained in gear drive construction can only be fully exploited in the self-contained coaxial gear unit

    This cylinder rotates around its axis and transmits the rotating effect to the balls. The material fed through the mill is crushed by the impact and ground as a result of the friction between the balls. The drive system can either consist of a central drive (central gear unit: helical gear unit or planetary gear unit) or a girth gear unit with pinion design (central gear unit: helical gear unit)
