Nano-sand mill dispersion principle and characteristics


Nano-sand mill, also known as a bead mill. The powder materials and liquid materials for solid - liquid abrasive lax lax a class equipment. Within the vertical or horizontal cylindrical shaft axially pierce several grinding disc apparatus radial shaft, a ring or a pin. Filling tube diameter of 0.6-2 mm milling media. Cylinder equipped with a jacket, a central through cooling water to absorb, drain away the heat generated by the grinding process of the slack. Material pumped through the barrel, and grinding media together at high speed rotating grinding disc intense agitation, the tube wall along the disc is thrown back, slurry flow between the plate reciprocating cycle, so that the solid material is uniformly lax gradually to the liquid material in. Unloading method varies with the material viscosity level. Usually the choice of the suspension through the slit-shaped outflow hole mesh, aperture width of grinding medium 1 / 2-1 / 3. Grinding media, began to use sand, it said sander; then use glass beads, it is also called a bead mill. Today, the choice of the grinding media are: corners rounded sand, glass beads or by a variety of wear-resistant material, the steel ball and steel scraps. Sanding machine for paints, dyes, inks, pharmaceuticals, photographic film, audio tape and other industrial sectors.
Lax principle: the main motor shaft driven by triangle belt slack for the high-speed movement, lax lax disk drive shaft grinding media campaign to generate friction and shear forces so that the material to be milled and lax. The selection of the mechanical seal device because it arrives so fully enclosed, thus eliminating the production of solvent evaporation losses, reduce environmental pollution. On the other hand, because the air is prevented from entering the work cylinder, to avoid the dry skin material in the production process of consolidation may be formed.
Features: This device grinding chamber all hive - grinding cylinders, lax plate, bush, gland, front and rear cover closure plate, sieve rings and all the material for the yttria-stabilized zirconia (YZr), with high wear resistance, stability Very good, clean. Abrasive disk has a high line speed (maximum reaching 26 meters per second), the minimum configuration of the grinding beads (as small as 0.2mm), the grinding efficiency coefficient, so that the fineness of goods Dana Mi (up to 50 nm ). Role Selection parting sieve ring, so that the material and leave the end of the grinding media produce barrel, after the material. The machine has a double face import dynamic sealing systems, multiple and complex forced cooling system, and a full range of PLC automatic control and protection system, according to customer requirements full touch-screen operation, and complete on-line long-distance monitoring, suitable for batch jobs.
