Ball mills are predominantly used machines for grinding in the cement industry. Although ball mills have been used for more than one hundred years, the design is still being improved in order to reduce the grinding costs. HOLTEC has undertaken Performance Optimisation of the cement grinding circuits by doing process

The poles of the gearless or synchronous motor (also called wrap-around motor or ring motor) are directly installed on the pole flange of the mill shell, turning the mill body into the rotor. The stator is then wrapped around the mill. The gearless motor is fed by a cycloconverter which has a rated output frequency of around 5 Hz for the GMD drive.

The selection of the motor enclosure is typically left to the discretion of parties other than the motor manufacturer. However, the motor manufacturer can choose to provide an enclosure that exceeds the requirements of that specified by the purchaser. 1. Totally Enclosed Fin-Cooled Motor (TEFC)

The tower provides structural support upon which the nacelle and rotor blades stand and is made of tubular steel, concrete, or steel lattice. Naturally, the materials must be strong and robust in nature to withstand harsh environmental conditions and strong winds. AS 1302 Grade 230S rolled (concrete reinforcing bar) bar.

For general reference cement is usually shipped in sacks containing one cubic foot of material. A barrel usually holds 4 cubic feet. Cement will deteriorate with age and will quickly absorb moisture so it should be stored in a dry place. For best results the sand and gravel used should be carefully cleaned free of humus, clay, vegetal matter, etc.
