Ball Mill Crushing by tube-mills were first introduced into the crushing departments of cyanide plants when it was found that for crushing finer than 30-mesh other types of crushing machinery were not efficient. In order to crush with one pass, these mills were made 18 to 22 ft. (5.5 to 6.7 m.) in length. Pebbles were used as a grinding medium and the mills were lined with either silex blocks

The important of crushing your ore and rock fine and properly is often forgotten. The finer you crush, the higher your ball mill tonnage and capacity will be. The effect of ball mill feed size and how it affects circuit throughput can be hard to estimate. Here we described a method of designing a crushing plant using power drawn and power rate to define reduction ratios in each stage of crushing.
F 80 is the mill circuit feed size in micrometers. Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles. [citation needed] But note that the term 'rod mill' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals.
These may include packing in a crusher, oversize feed or improper ball and rod sizes in a tumbling mill, and coating dry in grinding. Laboratory Tests for Determining Work Indexes.

For efficient operation of ball mills necessary to observe the right balance between balls size and feed material size. If the feed material contains many large lumps and grinding balls can’t crush them, it leads to a gradual accumulation them between the balls. As a result, mill suspends own operation. In these cases, need to reduce the size

The standard Bond Ball Mill Work Index test procedure is firstly to stage crush the feed to minus 3.35mm, and size a representative sample. The test then involves a series of batch grinds in a standard Bond mill. A Bond mill is 0.305m by 0.305m, with rounded corners, a smooth lining, and runs at 70rpm. The charge consists of 285 balls, weighing a

Crushers are used to reduce particle size enough so that the material can be processed into finer particles in a grinder. A typical processing line at a mine might consist of a crusher followed by a SAG mill followed by a ball mill. In this context, the SAG mill and ball mill
crushing and grinding; and F80 and P80 are the 80% passing size of the feed and the product ( m), respectively.

The standard Bond ball mill grindability test is a closed circuit dry grinding test with a
The final particle size depends on the speed of rotation and on the size of the balls. c) Roller mills The mill consists of two or more steel rollers which revolve towards each other and pull particles of the stone material through the space between the rollers, the space being known as “the nip”. The size of the nip can be adjusted for

In Grinding selecting calculate the correct or optimum ball size that allows for the best and optimumideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do Often the ball used in ball mills is oversize “just in case” Well this safety factor can cost you much in recovery andor mill
Could this really be a function of crush size alone? In researching the topic, I discovered little in the way of prior investigation, though found a similar experiment done by Kai Troester on a lower OG beer. His results also showed that a finer crush did increase efficiency, but attenuation was noted to be independent of crush size.
