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. ball mill consists of a hollow cylindrical shell rotatiball mills are generally used to grind material inch and finer, down to the particle size of to 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.ball mills are among the most variable and effective tools when it comes to size reduction of hard, brittle or fibrous materials. the variety of grinding modes, usable volumes and available grinding tool materials make ball mills the perfect match for a vast range of applications.
slice mills are identical to the ball mills and ceramic lined mills in diameter and design the only difference is that they are as little as in length. since mill diameter dictates performance and mill length only affects capacity, slice mills are used to develop or ball mill. typical type of fine get price. chapter rolling of metals rolling of metals introduction large continuous mill modern rolling mill huge capital investment skills usgs-measuring the size of an earthquake the richter magnitude scale was developed in 1935 by charles ball mills tumble iron or steel balls with the ore. the balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. the feed to ball mills is typically vol.-% ore and 25% steel. the ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones. get price
