Subject: The production steps of silicon carbide powder
Content: In recent years, with the rapid economic development, the demand for the processing and utilization of silicon carbide powder has also been greatly enhanced.   The production steps of silicon carbide powder are as follows:   (1) Take the silicon carbide raw material, crush it with a crusher, and sieving it to no more than 5mm silicon carbide particles, and then use a shaping machine to shape it to no more than 2mm silicon carbide particles, and its elliptical particles account for more than 80%.  white fused alumina manufacturers   Then it is pickled to remove impurities and dried;   (2) The above-mentioned dried silicon carbide particles are pulverized into silicon carbide powder with d50=9.5-11.5 μ m by a mill. When pulverizing, the current of the main machine of the mill is set to 65-75A, and the flow rate of the fan is set to 40-50m3/ min, the speed of the analyzer is 400--600 rpm;   (3) Then use the vortex air classifier to classify the silicon carbide powder. When classifying, the fan flow rate of the vortex air classifier is 25-43m3/min of the coal gangue crusher, and the speed of the classifying wheel is 2600-3300 rpm. The particle size ds94=6.5-5.5 μ m finished product A is separated from the classification port, and the semi-finished product ds94 ≤ 5.5 μ m is separated from the cyclone port;   (4)  Separate the semi-finished products from the cyclone of the vortex air classifier and use the impeller air classifier for secondary classification. When classifying, the flow rate of the fan of the impeller air classifier is 25-10m3/min, and the speed of the classifying wheel is 1300-- 1700 rpm, the particle size is ds94=4.5-3.0 μ m finished product B from the classification port, and the by-product dryer equipment is separated from the cyclone port. www.hslabrasive.com
