Abstract

The invention provides a boron carbide accurate grinding aid and a use method thereof. The accurate grinding aid is prepared by mixing an alcamines substance, an amide substance, inorganic salt, a defoaming agent and any parts of water. The boron carbide accurate grinding aid is added while accurate grinding, can improve slid content of slurry and ore grinding efficiency and enables particle size of the boron carbide to be distributed in a concentration manner.

Description

technical field [0001] The invention relates to the field of boron carbide fine grinding, in particular to a boron carbide fine grinding grinding aid and a use method thereof. Background technique [0002] Boron carbide is a superhard material, its hardness is second only to diamond and cubic boron nitride, so it is very difficult to finely grind boron carbide, and most of the mechanical energy is converted into heat energy during the fine grinding process of boron carbide, which is wasted , At the same time, as the fineness of boron carbide powder increases during the grinding process, the surface energy increases, and the fine particles will aggregate, resulting in a sharp drop in grinding efficiency. [0003] Therefore, there is an urgent need to develop a method that can improve the above phenomenon. [0004] In the prior art, there is a lack of research on the method of boron carbide fine grinding. After research, the inventors provide a grinding aid that can improve t...
