Airflow grinding temperature without medium smashing: low melting point, thermal sensitivity, fibrous, polymer polymer powder; flammable, explosive, easy oxidized material for ultrafine processing Moques hardness; inert gas Realize the closed circuit cycle, the inert gas circulation is used.
Green carbonate fine powder is an engineering processing material for solar photovoltaic industries, semiconductor industries, and piezoelectric crystal industries. The so-called quality quality of green carbolic silica is in relation to demand, and 1200 and 1500 are a number of points. The larger the number of points, the smaller the particles. If the demand is from 1500 silicon carbide, the center value should be 8.5 microns, and the quality is good is to see if the particle size of this range is a comparison. The airflow pulverizer uses unique processes to solve this difficulty.
Green carbonate fine powder refers to the material of # 280 with fine to # 2500, the smaller the model, the particle size is compared, such as the median value of # 1200 is around 9.5, The median value of # 1000 is about 11, Shandong Erphoni green silicon carbide production process stream: a production process of silicon carbide fine powder, which is characterized in that the steps are as follows:
Take silicon carbide feedstock, crushed The machine is broken, and sieved to a silicon carbide particles not more than 5 mm, and the plastic machine is placed to a silicon carbide particles not more than 2 mm, and the elliptical particles are more than 80%, and then acid wash Hybrid, dry;
The above dry silicon carbide particles were pulverized into silicon carbide powder of D50 = 9.5-11.5 μm, and when pulverized, the mill is set to 65-75a. The fan flow is set to 40-50m3 / min, the analyzer speed is 400-600 rpm;
then classify the silicon carbide powder with a vortex gas flow classifier, vortex gas flow grading The fan's fan flow is 25-43 m3 / min, the grading wheel speed is 2600-3300 rpm, from the fractional mouth of the finished product A, and the cyclone is divided into semi-finished products of DS94 ≤ 5.5 μm.
Shandong Erfa powder equipment has been specially used to smash the silicon microofweed, the technology is mature, mainly composed of Shandong El Pie MQW series fluidized bed gas flow pulverizer. Physics of hard wear resistant material such as high purity quartz, silica, etc.The characteristics are different, and the production requirements are different from the application, and the ultrafine pulverization classification equipment for manufacturing production is customized.
