Ball Mills - an overview ScienceDirect Topics

3.6.1.1 Ball Milling A ball mill is a type of grinder used to grind and blend bulk material into QDs /nanosize using different sized balls. The working principle is simple; impact and attrition size reduction take place as the ball drops from near the top of a rotating hollow cylindrical shell.

Throughput optimisation in milling circuits

SAG mill discharge control is quite involved due to few interactive variables, such as mill discharge sump level, classification hydro-cyclone variables (feed density, flow and pressure) and water feed rate to the sump. Model predictive control (MPC), which is a multi-input multi-output (MIMO) controller, is very suitable for this purpose. If a particle size analyser is installed it can be ...

Optimization of mill performance by using

The performance of ball mills is very sensitive to the volumetric mill filling which influences grinding media wear rates, throughput, power draw, and product grind size. A pilot plant investigation with an overflow mill discharge has been conducted. For a given throughput, it seems that the pool size has a major influence on the product grind.

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. The axis of the ...

Optimization of continuous ball mills used for finish ...

10/12/2004  It was obvious, too, that the L/D ratio influences the specific energy demand and the mill throughput as well. Therefore, a huge test program was carried with a semi-industrial ball mill, which was operated in closed circuit. The mass-specific surface area of the two feed materials (intermediate product) used were quite typical for industrial semi-finish grinding plants. The values were 2200 ...

GEOMETALLURGY APPLIED IN COMMINUTION TO MINIMIZE DESIGN RISKS

(Starkey Dobby, 1996) and Bond ball mill work index (BWI) (Bond, 1961), provide unquestionable margin of design safety in the plant (David, 2013). However, this approach does not consider the inherent variability of the orebody and, therefore, can lead to results which are not representative for some of the ore types. Monte Carlo simulation is a mathematical technique that allows accounting ...
