Oleg D. Neikov in Handbook of Non-Ferrous Metal Powders 2009. Tumbling Ball Mills. Tumbling ball mills or ball mills are most widely used in both wet and dry systems in batch and continuous operations and on a small and large scale.. Grinding elements in ball mills travel at different velocities. Therefore collision force direction and kinetic energy between two or more elements vary strength mill feed size depends on in -situ rock structure rock strength blast intensity and primary crusher specifications and param eters (Simkus and Dance 1998). The first step in developing an accurate mill throughput model is to have in -depth knowledge of the geological parameters that define

Factors Affecting Ball Mill Grinding Efficiency

The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency a) Mill Geometry and SpeedBond (1954) observed grinding efficiency to be a function of ball mill diameter and established empirical relationships for recommended media size and mill speed that take this factor into account. As well mills with different 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.

Mill power draw modelsSAGMILLING

Mill Power Draw Models. The mill power draw models are used to predict how much power will be consumed by a particular type of mill mill geometry and set of mill operating conditions. This power is transferred to the ore and used to predict the throughput when combined with the specific energy consumption models. 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.
