The types of abrasives can be divided into two categories according to the material: non-metallic abrasives and metallic abrasives:
Non-metallic abrasives generally include copper ore, quartz sand, river sand, corundum, glass, etc. Due to the extremely high crushing rate of non-metallic abrasives, the production of dust, serious pollution and low efficiency, has been gradually replaced by metal abrasives.
Metal abrasives are represented by: cast steel shot (high carbon and low carbon), low shell steel shot, steel grit, stainless steel shot, wire cut shot, bearing steel grit, etc. All kinds of metal abrasives have different characteristics and are suitable for different occasions.
