Centrifugal ore grinder

Technical Field

The utility model relates to the technical field of ore processing, in particular to a centrifugal ore grinding machine.

Background

Ore refers to a collection of minerals from which useful components can be extracted or which themselves have some property that can be exploited. Can be divided into metal mineral and nonmetal mineral. The unit content of useful components (elements or minerals) in the ore is called ore grade, the precious metal ore such as gold and platinum is expressed in grams/ton, and other ores are expressed in percentage. The value of the ore is usually measured by the ore grade, but the ore value is also influenced by the composition of gangue (useless ore or ore with little useful component content and unavailable useful component) and the amount of harmful impurities in the effective component ore. After ore mining, it is often necessary to grind the ore to a powder by means of a grinder before refining the pure metal. Various grinding machines are available on the market at present, but the grinding force of the grinding machines is general, and the grinding machines cannot grind metal ores into powder efficiently, so that the use requirements of people cannot be met, secondly, the existing ore grinding machines cannot screen the ore powder, and the finished product can be doped with ore particles which are not completely ground, so that the quality of the finished product is influenced.
