herein, an innovative approach for determining the grinding media system of ball mill based on grinding kinetics and linear superposition principle was proposed. the optimal media ball size of 0.45 mm, 0.45 0.15 mm, and 0.15 mm feeding samples were mm, mm, and mm, respectively.this ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. due to the difference of its slurry discharging method, it is divided to two types: grid type ball mill and overflow type ball mill.
mm and water enter the feed end of a sag mill through a feed chute; the ore is milled in the shell and milled product exits through grates and pulp lifters at the discharge end the discharge is screened and the undersize, typically less than mm provides ball mill feed and the oversize is returned for further milling.after 1000 tons material loading into the mill, the flap opens for a certain time and kg of grinding balls should enter in grinding channel then flap closes and the grinding balls feeding stop. similar work scheme observed under the condition the person engaged in flap opening
ball mill is a type of grinder used to grind materials into extremely fine powder for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering.and works on the principle of impact: size reduction is done by impact as the balls drop from near the top of the shell.
