Brown corundum is mainly bauxite, coke as the main raw material, smelted abrasive, we all know, for this product, the higher the purity, the higher the product quality, and the greater the hardness, so improving the purity of the product is what everyone is doing, how to improve it? Let’s take a look together:
1. For 220 mesh with fine abrasive material impurities are large, the subdivision content is high, air washing and water washing are not competent, can only use pickling treatment, but this method consumes a lot of water and the cost of secondary drying is high; High temperature is currently a good way to purify brown corundum abrasives.
2. The investment in air washing treatment is small, the efficiency is high, and the cost is low, but it cannot all remove the ultrafine particles attached to the surface of the abrasive, and is generally used to clean the coarse particles of the abrasive; The water washing treatment process is complex, which is obviously helpful to improve the purity of the abrasive, but due to the large amount of water, secondary drying is required and the cost is high.
3. Under normal circumstances, we carry out effective purity treatment on the impurities in the smelting brown corundum abrasives, which is due to the insufficient bauxite resources, the quality of corundum blocks is difficult to meet the quality requirements of upstream products, so the production, processing and subsequent treatment of abrasives are particularly important.
In summary, the high temperature treatment, air washing treatment, and raw material selection of brown corundum can improve its purity, and each method adapts to different conditions, and we choose the appropriate method according to the actual situation to better complete its purity treatment.
