The prior common brown corundum abrasive classification method mainly comprises a dry separation method and a moisture separation method. The dry separation method also comprises a sieving method and an air flow method; the water separation method includes overflow method and sedimentation method. Generally, the brown corundum abrasive grain size of 4-220 meshes mainly adopts a sieving method; 230-1500 meshes only can use an airflow method, an overflow method or a sedimentation method because of high content of fine powder, low screening efficiency and difficult separation of granularity; the air flow method has the advantages of large investment, low efficiency and high grading cost, and fewer users are adopted in the brown fused alumina industry at present; the overflow method can realize continuous production and has high efficiency, but the water consumption is large; the sedimentation method can only intermittently produce and has low efficiency, but the water consumption is smaller. Currently, overflow methods are classified as the main stream of the industry.
