Ball mill is a kind of high and fine grinding machine widely used in mining industry. Usually, the discharge particle size of the ball mill will be controlled between 0.075-0.89mm, which can obtain powder like materials. However, sometimes under the influence of some special reasons, its discharge particle size will be too large and uneven.

Grinding is the process of achieving particle size reduction through attrition and compressive forces at the granular level. The grinding media in a ball mill is typically steel or ceramic balls of varying sizes, depending on the feed size, work index of the ore and the size reduction and distribution required in the discharge.

A ball mill is a type of grinder used to grind or blend 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. A ball mill consists of a hollow cylindrical shell rotating about its axis. T

If you do not need a deep primary grind, a retrofit/conversion might be of value. A very high impact opportunity to increase your ball mill tonnage. A conversion is cheap in price as you can read in the footer. The cost of a ball mill conversion from overflow to grate discharge is 'fairly' affordable at $65,000 for a 13′ x 15′ mill.

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
