09/05/2018 · Construction: It consists of a hollow cylinder which is mounted on a metallic frame in such a way that it can be rotated on its longitudinal axis. The length of the cylinder is slightly higher than its diameter. The cylinder contains balls that occupy 30 to 50% of the mill volume. The ball size depends on the size of the feed and the diameter ...

08/03/2021 · Overflow discharge ball mill can grind ores into the size under mm, so it is very suitable for the second grinding system. The capacity of it is about 15% lower than grate discharge ball mill in the same specifiion, and the loaded grinding medium is also less than that one. Rod mill Fote rod mill

A ball mill of 125 cm diameter is operating at 32 rpm, which is 80% of the critical speed. Determine the size of the balls to be put into the mill. (Answer: Size of the ball = m). 27. A certain crusher accepts a feed of rock having a feed size of cm and a discharge product of cm. The power required to crush 12000 kg/hr is kw ...

This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types: grid type ball mill and overflow type ball mill.

Primary, coarse grinding (up to 400 mm feed size) Grinding media is grinding feed plus 412% ball charge (ball 125 mm) High capacity (short retention time) Less sensitive to feed composition (critical size material) SemiAutogenous Mill Note the size of the mill: Why does the diameter need to be so big?

Optimization of mill performance by using online ball and pulp measurements Soon after a stop, a mill is a dangerous place to enter for the personnel tasked with taking measurements or samples. Crash stops are difficult to handle. The mill and all feed streams should be stopped simultaneously but, often, they are stopped around about the same time.
