The main technical character of the invented lining board is that its cross-section is a polygon of 5-20 sides with round vertex. The shortage of poor penetrating and mixing abilities of the grinding body and material inside the grind machine can be solved by this invention. Therefor, it can raise the pulverous grinding efficiency and production quantity of machine and can lower its power comsumption. The invented lining boards are suitable for use in the industries of metallurgical, chemical and construction material to carry on the pulverous grinding of material. |
