The existing production methods of white aluminum oxide are mainly crushing or ball mill crushing, resulting in uneven particle size and large particle size dispersion. The separation system of carborundum includes a mixing device which mixes carborundum and water to form the original liquid flow; a separation device artificial corundum which connects with the mixing device to separate the original liquid flow; a separation device which connects with a shunt device; a shunt device which connects with a subpackage device.


The separation system introduced in this paper can separate sand particles with similar particle size. The white corundum grinding of silicon wafer usually uses natural emery or artificial sand to match with water and grinding aids in a certain proportion, and then through the positive and negative movement of the upper and lower grinding discs of the grinder, the aluminum oxide blasting abrasive can be grinded through the friction between the medium (grinding fluid) and the grinding disc, so as to achieve the purpose of grinding.


The aluminium oxide abrasive grit separated sand particles are not easy to scratch or damage the surface of the silicon wafer during the grinding process So as to improve the yield of silicon wafer. The emery separation system includes a mixing device for mixing Emery and water to form the original liquid flow, a separation device for separating the original liquid flow 3 is connected with the mixing device, a separation device is connected with a shunt device, aluminum oxide abrasive blasting grit and a shunt device is connected with a subpackage device.


According to the test, the particle size distribution of fused aluminum oxide W14 silicon carbide is: 7-l0um ≤ 8.4%, 10-14um ≥ 76.6%, 14-20um ≤ 15%, the average particle size is 13.5um, and the maximum particle size is 20um. During the grinding process, the abrasive disk first contacts the surface of the silicon wafer in the process of pressing operation, which is very easy to scratch or damage a point on the surface of the synthetic corundum price, forming pitted white spots, resulting in the decrease of the yield.


In order to solve the above black synthetic corundum problems and improve the yield of silicon wafer, the diamond separation method adopted is as follows: mixing: mixing the emery and water into the original liquid flow; separation: screening the original liquid flow, filtering the large-size emery, and separating to obtain the separation liquid flow; separation: flowing the separation liquid into the mixing and settling to obtain the 220 grit aluminum oxide separation liquid flow; separation: layered separation of the separated liquid flow after sedimentation.
