Effect of operating parameters in stirred ball mill

Effect of operating parameters in stirred ball mill

Dec 01, 1989 In the present work, various operating parameters such as stirring speed, pulp density and the use of grinding aids have been studied using a laboratory stirred ball mill. It has been found that the mill operates most efficiently at low stirring speeds and high pulp densities, as long as the viscosity is controlled within limits.

Influences of operating parameters on dry ball mill

The influences of operating parameters such as mill speed (% of Nc), ball filling ratio (J), powder filling ratio (fc), ball size distribution (%), grinding aid dosage (g/Mg) and grinding time (min) were investigated in this study. The dry grinding test conditions are outlined in Table 2. The grinding tests were conducted as a batch process; after the completion of every grinding test, the mill content was …

Optimization of mill performance by using

The pulp density is an important parameter which influences the grinding efficiency. In iron ore, for instance, a variation of 2 to 3% solid content in the slurry could lead to a difference up to 10% on the energy (kWh/T) for a similar grind.
