Ball mill Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.

The hardness of grinding media ball how to choose balls

Keep the hardness just right. When we choose wear-resisting grinding media ball, often be the hardness problem of the grinding media ball.About the hardness, not the bigger the better, is the appropriate hardness value. Simply put, the higher the hardness, the greater the impact reaction during the process of falling, increasing the ball loss.

Effect of Grinding Media on Flotation Chemistry

To investigate the electrochemical characteristics of grinding media materials and minerals used in this study, electrodes of pyrrhotite, pyrite and mild steel were prepared by mounting the samples in lucite tubing of 0.625 cm I.D. with a 3M Scotch-Weld structural adhesive, so that about 0.16 cm² of their surfaces were exposed to the solution

Grinding Media Interaction & Effect on Mineral Floatability

Grinding in a steel mill adversely affects the floatability of pyrrhotite. An electrochemical interaction between the steel media and the mineral, enhanced by the severe abrasive condition in the grinding mill, appears to be responsible for the reduced floatability of pyrrhotite and for the increased consumption of grinding media during wet grinding.

The grinding tests were carried out in a vertical mill (JM-2, Changsha, China) at a constant rotational speed of 450 rpm. To better verify the effects of the grinding media on grinding products and chalcopyrite flotation behavior, the mill barrel was made of corundum with a volume of 200 mL, and the top of the stirring rod was covered with a nylon material.

A discussion on the measurement of grinding media wear

Iwasaki et al. proposed a corrosion model for the grinding media, involving two types of galvanic cells, as shown in Fig. 3.In the differential abrasion cell, the abraded surface acts as an anode, whereas the un-abraded surface acts as a cathode, and the corresponding corrosion reactions are iron oxidation in the first area and oxygen reduction in the second.
