rpm ball mill

Ball MillOperating Speed - Mechanical Operations Solved . The critical speed ofball millis given by, where R = radius ofball mill; r = radius ofball. For R = 1000 mm and r = 50 mm, n c = 30.7rpm. But themillis operated at a speed of 15rpm. Therefore, themillis operated at 100 x 15/30.7 = 48.86 % of critical speed. Get Price

Ball Mill

The ball mill is one of the most widely used super fine grinding machine in the industry and it is the key grinding equipment after materials have been crushed.

Classifier

Spiral separators, which are also called spiral concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.

Disk Granulator

The disk grain making machine is suitable for the mixing ball equipment of the nutrient content is 10-30%.

Agitation Tank

Stirring tank is suitable for mixing before flotation, for various metal and ores to adequately mix pharmaceutical and pulp, and it can also be used for mixing other non-metallic minerals.

Chinaware Ball Mill

Chinaware ball mill is mainly used for the mixing and grinding of materials, and the fineness of the final products is even, thus saving motive power. It can be used in both dry grinding and wet grinding.

Shaking Table

In the metallurgical industry, shaker table is mineral processing equipment used for sorting fine material.
