ultrafine mill is a production of ultrafine powder equipment, the equipment produced by the finished product in addition to measuring the fineness of the purity of the finished product, only the purity of the finished product was better to meet the needs of other industries, but In the actual production line finished product purity is relatively easy to influence Here to analyze what the reasons for the impact of ultrafine mill, the purity of the finished product. In general, the purity of finished products produced by the equipment is affected by many factors. For the convenience of customers, has summarized some problems that affect the purity of finished products. Here's a brief introduction: First of all, the ultrafine mill is different, purity is also different, for example, ultrafine mill equipment, artificial graphite powder production, its purity than the grinding oil coke or pitch coke purity is lower, the particle size should be more coarse; Second, ultrafine mill feed particle size will also affect the purity of finished equipment, in general, feed particle size, high purity; Once again, the impact of the amount of feed, too much feed, the throttle easy to plug, low output, fine particle size, the solution is to suspend the feed or stop scraping out some of the material reproduction; or reduce or shut air valve; into Feeds a foot, the air volume, lower milling purity, coarse particle size. Can increase the feed, or open more than air duct valve; It is the influence of the air volume of the ultrafine milling equipment on the purity of the finished product. The air volume has a large particle size and becomes coarse. The air volume has a small particle size. The above analysis of the factors that affect the purity of finished products of ultrafine mill equipment can be used as a reference to check the purity of finished products in the production process of the equipment to help the equipment better serve the production process of ultrafine powder.
