With the use of the fine range of Ball Mill, Ball mill using targeted more and more strong, also appears a kind of no longer need to join the ball, directly to the broken material as medium is broken, thus greatly reducing equipment equipment complexity, here to explain:
No medium in ball mill in the specification and speed under fixed conditions, material to the volume and size of ore block ratio directly affect the grinding process, the production of attention. Production practice proves: material filling rate in 30% ~ 40% between appropriate. If the feed rate control is not good, no medium in ball mill material level fluctuation, could have caused" bloated" ( high level ) or" empty" ( low level ) phenomenon. Therefore, requirements of production to ore quantity and feed size ratio to strive to maintain a stable, but requires both stable, if only to keep the number of stable, but the size ratio of improper, production is not normal. Particle size distribution, mainly large ore can not be less, if in the special case of large ore is low, a small amount of a large steel ball. The lump ore ratio more is not better, but less production effect is not ideal, should according to their respective ore properties, by the experiment and production practice to determine.
Only the ball mill structure gradually simplification, efficiency maximization, cost is low, In the fierce competition in order to achieve their own a space for one person! Get Ceramic Ball Mill, Ball Mill, Beneficiation From http://www.rawmill.com
