Description

Technical Field

[0001] The invention relates to the technical field of corundum abrasive production equipment, and in particular to a corundum abrasive production equipment and a use method thereof. Background Art

[0002] Artificial corundum has good toughness, sharpness, low sand consumption, good finish when grinding workpieces, stable chemical composition, wear resistance, acid and alkali resistance, sharp edges and corners, and high refractory temperature. It can be widely used in grinding wheel manufacturing, sandpaper and sandpaper production, refractory materials, steel smelting, metallurgy and chemical industry, ceramics, glass, cement and other fields. Before using corundum, it needs to be crushed, that is, made into abrasive, so a device that can crush corundum is needed.

[0003] When using a traditional corundum crushing device, the corundum raw materials to be crushed are generally poured into a crushing box and crushed by the crushing roller. However, during the pouring process of the corundum, due to the limited space in the crushing box, if too much corundum raw materials are poured, it will cause the raw materials to accumulate and clog, affecting the feeding speed. In addition, when encountering large pieces of corundum with a smooth surface and high hardness, it is difficult for the crushing roller to eat it, which also reduces the crushing efficiency. Summary of the invention
