Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel.

This control room mounted instrument controls the temperature of the feed stock at the exchanger outlet by accurately positioning the valve TCV 102 that regulates the steam flow to the exchanger. TT 102 measures the temperature of the feedstock at the exchanger outlet. This measured temperature is sent in the form of electrical signals to TIRC 102.
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.
Control stabilization for ball mills BrainWave stabilizes the operation of ball mills, resulting in improved particle size distribution and increased fines production. It is able to stabilize the particle size distribution by continuously adjusting the mill load, typically achieved by adjusting the secondary crusher mantle gap to regulate production rate for the crushing plant.
