Description

technical field [0001] The invention relates to the field of non-ferrous metal grinding machinery, in particular to a multi-layer impact non-ferrous metal grinding machine. technical background [0002] The separation of non-ferrous metal mixtures is generally based on the difference in specific gravity of various materials in the mixture. For example, the separation of copper and aluminum mixtures is based on the difference in specific gravity between copper and aluminum, and the method of air flotation is used to separate copper and aluminum. Separation of non-ferrous metals by using the difference in specific gravity of materials, although the multiplicity of each component in the material is different, if the difference in particle size is too large, it is difficult to separate or affect the separation rate (cleanliness) by air flow flotation. Therefore, when the particle size difference of the mixed non-ferrous metal material is too large, it is necessary to screen the ...

AI Technical Summary

Problems solved by technology

If there are too many particle size levels, too many airflow flotation equipments are required, resulting in complex production, occupying a large space, and affecting efficiency; if the non-ferrous metal mixture is ground to a certain particle size range, since non-ferrous metals generally have relatively good ductility (elongation rate) ), when grinding, it is easy to adhere to the grooves on the surface of the grinding body and the liner and fill up the grooves to affect the grinding efficiency and even cause the grinding body to fail

At present, there is no industrialized device capable of efficiently grinding non-ferrous metals in China
