The mill can be used for pregrinding and finish grinding as well. This mill system has better reliability and energy savings over ball mill, roller mill and roller press. ...
In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill & ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.
The surface area, size distribution and specific energy consumption for the material ground in the ball mill were used in conjunction with the single-particle data to provide an assessment of the energy efficiency of ball milling.
Main Strengths of Energy-saving Ball Mill. Compared with the traditional ball mill, the energy-saving ball mill owns its unique advantages, such as the 18-25% reduction of the motor power, the 70% lubricants saving, 90% decrease of the cooling water and more than 20% comprehensive energy saving.

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of 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 rotati
Colloid mill is a machine used in the disintegration of solid particles or droplet size of a liquid present in suspension or emulsion. The machine consists of an inlet (which is subjected to a tremendous shearing action that effects a time dispersion of uniform size) and an outlet.
