<br class="break/" /><br class="break/" />The raw material of <span style="color: #800000;"><a href="https://www.xinliabrasive.com/White-Fused-Alumina.html" style="color: #800000;"><strong>white fused alumina</strong></a></span> is Al2o3 crystal of furnace core material or bulk material of grinding wheel factory, the content is more than 98.5%, and its particle size is 36 #, 46 #, 100 #. The content of SiO2 in the raw material used should be as little as possible to prepare white fused alumina grinding powder.
<br class="break/" /><br class="break/" />The equipments used include ball mills (the barrel specifications are 150X300, 260X300, and 350X500), glass cylinders (300X500), high-temperature electric furnaces, ovens, washing tanks and ventilation boxes.
<br class="break/" /><br class="break/" />Put a group of quenched steel ball copper raw materials with different diameters into the drum, add water, put a rubber squeegee to seal the cover, then rotate the drum, and crush the abrasive under the percussion of the steel ball.
<br class="break/" /><br class="break/" />The purpose is to wash off the iron impurities in the abrasive, followed by pickling and water washing, and then sorting in the glass tank by the water sorting method.
<br class="break/" /><br class="break/" />In the drying box, heat up to 100 ~ 200 ℃ and dry, and grind the agglomeration with a glass grinding rod or a horn spoon after the drying.
<br class="break/" /><br class="break/" />Put the white fused <a href="https://www.xinliabrasive.com/White-Fused-Alumina.html"><span style="color: #800000;"><strong>alumina grinding powder</strong> </span></a>into the electric furnace or muffle furnace, from normal temperature to 850 degrees, sometimes up to 1200 degrees for W0.5-w1 grinding powder, and then keep it for 5 hours.

The abrasives used in embedded grinding and fine polishing need to be treated. The soaking requirements are: 0.4g of stearic acid, 20g of grinding powder, and 200ml of aviation gasoline, and soaked in a ground glass bottle for more than seven days.
