Modification of production throughput of ball mill

Hello Dear Friends, We are working in a plant with single stage grinding using three parallel wet three compartment ball mill. Each ball mill operates in a close circuit with Classifier. The fineness of ball mill product is OK so the circulating load is insignificant (44 Kg/h). The overall data of

The use of ore fingerprints to predict geological

Despite the huge availability of data, the modern mining industry still models and optimises the ball mill performance (throughput, energy usage) by identifying a few attributes that characterise the feed material. It is unlikely that these are the only attributes that are the root cause of variable ball mill performance and high energy usage.

APPLIED GEO-METALLURGICAL CHARACTERISATION FOR LIFE

Batu Hijau has systematically improved long and short term mill throughput predictions since feasibility and commissioning in 1999. This has been achieved through a combination of ongoing improvement to the geology ore hardness and grade characterisation model, drill and blast optimisation and, by application of these data to model mill throughput.

Ball mill Wikipedia

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. A ball mill consists of a hollow cylindrical shell rotating about its axis. T
