The most Economic and Practical Ultra-fine Powder Processing Equipment, the Energy-saving and Reduce Consumption Equipment fro ultra fine Powder Processing HCH ultra-fine grinding mill is especially suitable for ultra fine grinding. With yearsâ?? accumulation of experience in R&D, the HCH Ultra-fine Grinding Mill is a new ultra fine pulverizing equipment designed by Hongcheng. This mill is widely used to grind any non-metal minerals with Moh's hardness below 7 and moisture below 6%, such as talc, calcite, calciumcarbonate, dolomite, bentonite, kaolin, graphite, carbon black, etc. HCH Ultra-fine Grinding Mill features in space-saving, completeness, wide usage, easy operation, smooth performance, high performance-cost ratio and high efficiency. HCH1395 Grinding Mill is the biggest ultra fine circle-roll grinding mill in China. Working Principle Technological process: The pre-grinding raw ore material will be crushed into particlesï¼?10mm and transport to the feeding hopper by the elevator, then feed into the grinding chamber by the feeder. The grinding rollers equip on the rotary table rotates around the centre shaft. There is flexible gap between the roller and ring. The rollers rotate outward by the centrifugal function to compress the fixed ring. The rollers also self- rotates around the roller pin. When material passed through the gap between the ring and roller, the material will be smashed by the rotating rollers. Four layers of rollers. Material will be grinded 1st time when passing the 1st layer of roller and ring. Then be grinded second, third and fourth time when loop through each layer rollers. Thus the materials were grinded sufficient and obtain much fine powder. The powder fallen down onto the bottom table by gravity will goes up to the classifier for separation by the airflow from blower. The qualified fineness passing from the classifier will be collected by the pulse bag collector as final product, while unqualified fallen down for regrinding till passing through. The powder goes with air flow into the pulse bag filter and collects by the discharging valve. The wind path is in circulation and the airflow is in negative pressure. There will be no dust escape, so the equipment can ensure a no dust operation in workshop. Application Range HCH Ultra-fine Grinding Mill is widely used to grind any non-metallic minerals with Mohs hardness below 7 and moisture below 6%, such as talc, calcite, calcium carbonate, dolomite, bentonite, kaolin, graphite, carbon black etc.. This kind of mill is especially suitable for ultra fine grinding. The fineness can be adjusted from 0.045mm(325 mesh) to 0.005mm(2500 mesh), whose range is much wider than that of traditional Raymond Mill.
