A ball mill also known as pebble mill or tumbling mill is a milling machine that consistsof a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.Get Price
Hongxing cone crusher is used for crushing ores and rocks and the advantages are reliable structure, high efficiency, easy adjustment and economy.
Spiral separators, which are also called spiral concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.
The convery belt is mainly composed by the expansion cylinder on both ends and the closed belts tightly knotted on them.

When liners, anddouble wave linersin particular, wear with circumferential grooves, slipping of the charge is indicated, and this warns of accelerated wear. When the top size ball is smaller than 50mm (2.5″) and mill speed is less than 72% of critical wear resistant cast irons can be used. For other conditions alloyed cast steel is recommended.See Details ➤

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically75vol.-% ore and 25% steel. The ball mill is operated inclosedcircuit with a particle-size measurement device andsize-controlcyclones.See Details ➤
Ball milling is a simple, fast,cost-effective green technologywith enormous potential.
