In this paper, the milling parameters of high energy ball mill (Fritsch Pulverisette 7) like vial geometry, number and size of balls and speed of the mill were modelled and discussed. Simulations through discrete element method (DEM) provide correlation between the milling parameters. A mathematical model is used to improve and develop this process.

difficultto process, transport, install and maintain the gearless ball mill because of its vast volume, and the coils cannot be decoupled freely. Therefore, this work proposes a module combined permanent magnet motor with wrapped type for mine ball mill (MBMWT‐MCPMM). Based on the principle of removing coils, the stator is modular-ized.

The stator frame of a synchronous motor has a wrapper plate that key bars and circumferential ribs are attached to. To support the machine, footings or frame mounts are used and slip rings and brushes are used to excite field windings with DC. ... Some other applications make use of synchronous motors such as ball mills, clocks, and record ...

magnetic field in the stator ( stator) is defined as slip frequency slip. Slip is the ratio between slip frequency and the stator magnetic field frequency, sli = p stator. The slip or the slip frequency is usually used to identify the operating point of the motor. When the rotor is in standstill, the slip is 1.

The stator core is mounted directly on the frame. Winding The winding process adopted by WEG is especially developed for the voltage and application the motor is intended for. The coils can be ... ball mills, cement mills, fans, exhaust fans, shredders and rolling mills employed in the cement, mining and steel industries, among
