Gradation of the crusher feed also has its effect upon the product analysis. This is true even of screened feed, although deviations from the average are not likely to be so wide as they are for unscreened material, such as quarry-run or mine-run rock.
The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1.
The first step in the crushing and screening process is to crush the bauxite ore. The ore is crushed by a crusher, which is a machine that uses force to break down the ore. The crusher can be a jaw crusher, a cone crusher, or an impact crusher. The type of crusher that is used depends on the size of the bauxite ore.
The material is crushed between the two jaws, so the wear of the liner is the main problem of the jaw crusher. And the types of wear and tear are mainly divided into the following cases. Bruise wear. In the jaw crusher, the ore is crushed and reduced to the required particle size.
The hopper, in a hard rock process, usually allows for dry feed of the rocks to the plant. It is designed for a direct feed by earth moving equipment. The size of the feed will depend on the plant's capacity (TPH). DOVE Ore Feed Hoppers are supplied in wide range of capacities, and are designed and engineered as parts that fit to make the ...
