Ball Mill: Operating principles, components, Uses

Jan 11, 2016· 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.

First, a Jar Mill grindability test requires a 5 lb. (2 kg) sample and produces a direct measured specific energy (net Hp-hr/t) to grind from the design feed size to the required product size. The second test, a Bond Work Index determination, results in a specific energy value (net Hp-hr/t) from an empirical formula.

MILLING CONTROL & OPTIMISATION Mintek

SEGREGATED ORE FEED CONTROL (Feed Ratio Optimisation) On milling plants fed by a segregated feed supply, such as a stockpile, the varying size and hardness of the mill feed material affects the residence time in the mill and the power drawn. When the load becomes critically high, the feed needs to be cut in order to “grind the mill out”.

Grinding control strategy on the conventional milling

the control loop will attempt to add water to Cyclone 1 sump to achieve a particle size of 15%+ 300 µm. If the hardness of the ore increases, the particle size in the mill discharge from ball mill 1 will increase. With the same water addition to sump 1 the particle size of Cyclone 1 overflow will increase. This will decrease the ratio, and hence

ball mill feed control using electric ear

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. The ball mill is operated in closed circuit with a particle-size measurement device and size-control
