1) WM1.5L Horizontal Sand Mill is a lab-used machine 2) The machines are especially suitable for grinding and dispersing high viscosity and fine materials. 3) The grinding efficiency is much higher than that of the common sand mills, the final fineness can come to less than 10 micron. 4) Adopts full Explosion Proof type 5) The grinding media is zirconium oxide beads or glass beads. The suitable size is 0.8mm-3.0mm. 6) It is composed of main engine, frame, feeding pump, cooling system and controlling system, cooling system of grinding and dispersion cylinder, conpressed air supply system and electrical contral 7) It's structure is vessed and vertical, can push the grinding medium to the entering and compress tightly while the machine are working 8) The end of exit comparatively the pressure is small, can make the grinding medium seprated into the vertical vessel and can put a high lasting effenciency. 9) Cooling fluid of mechanical seal adopts chemical fluid dissolved with material to assure the safety in a long time usage. 10) Internal circulated cooling/heating integrated system suiting temperature-sensitive materials
