Ball mill

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

Process control challenges and opportunities in mineral …

Grinding is often finished with a ball mill, which differs from a SAG mill, as it relies on the steel alone for grinding. A SAG mill may have 10% steel where a ball mill will typically have 30%. Classification is normally carried out in hydro cyclones with the product feeding either a flotation or leach circuit.

Electronic ear in SAG mill | Automation & Control …

 · We have an application in a SAG Mill where we have installed an electronic ear in order to listen the noise produced by the balls falling to the bottom of the mill. Our idea is to convert the amplitude and frequency of noise to a 4-20mA signal (or something else) in order to determine if the ball is crushing the mineral or the mill lining.
