Re: Cement milling. The normal method to charge balls into the ball mill is to position the doors at the top of the mill and remove them. Then to pour the barrels of grinding balls into the mill using an overhead crane. The exact grading of media required is identified by performing an axial test taking samples along the axis of mill.

Torsional vibration involves speed fluctuations of various components and the twisting of shaft sections while the machinery is rotating. Excessive torsional vibration can lead to failures of such items as shafts, couplings, fans, gears, engine dampers, and compressor oil pumps. These failures typically occur at a 45-degree angle to the shaft axis.

Load vibrations are a special form of vibration and permit a dynamic load analysis. Load vibrations can exert torsional, transversal and axial forces in rotating components and lead to premature fatigue. Other indicators of load vibrations are forces, displacements, deformations, strains and elongations, and require suitable load measurements.
