In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize just in case. Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

Jun 15, 2018Water Injection in Ball mill (for cement grinding) Ball mill generally produces a lot of heat, as the material advances in the mill, the temperature increases.

After 1000 tons material loading into the mill, the flap opens for a certain time and 10 kg of grinding balls should enter in grinding channel (approximately 33 pieces of 40 mm grinding balls). Then flap closes and the grinding balls feeding stop. A similar work scheme observed under the condition the person (miller) engaged in flap opening

The degree of milling in a ball mill is influenced by; Residence time of the material in the mill chamber. The size, density and number of the balls. The nature of the balls (hardness of the grinding material) Feed rate and feed level in the vessel. Rotation speed of the cylinder. Several types of ball mill exist.

Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced.

Jan 15, 2001Grinding was carried out in the laboratory ball mill described in Table 1, at a low ball load of 20% of the mill volume filled with the ball bed and a low powder load corresponding to a formal interstitial filling of void spaces of the ball bed of U=0.5. These conditions were chosen since it is known that they give first order grinding kinetics for normal grinding, both dry and wet.

All Grinding Mill Ball Mill Manufacturers understand the object of the grinding process is a mechanical reduction in size of crushable material. Grinding can be undertaken in many ways. The most common way for high capacity industrial purposes is to use a tumbling charge of grinding media in a rotating cylinder or drum.
