A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 of the mill volume and its size depends on the feed and mill size.Mill operations, inspections, process measurements, feed product characteristics and grinding performance, in order to improve mill output and reduction in power consumptions in the ball mill system. DIAGNOSTIC STUDY History of mill operations Operational performance System Design Description Grinding system performance testing Physical.
2. When the original ball mill drive system is replaced by the variable frequency speed regulation system, the mill will surely work normally at low speed, and the normal process control will be guaranteed.
