Horizontal type sand mill was designed to grind in high speed within a closed and pressure chamber to prevent the solvent from volatilization. This will ensure the operators working in healthy environment. Furthermore, save the energy to reduce the production costs. The work flows are begun by pumping liquid raw materials into the closed chamber, followed by starting Main motor to drive the grinding medium bead to rotate in high speed, which force raw materials dwell in a very narrow space and impacted by the high speed accelerated movements and rotation of the grinding beads, After mixing, emulsification, dispersing, kneading, and rotating, the raw materials will achieve its fineness. The finished raw materials will be out through the high speed rotation tungsten steel separation gap. Horizontal type sand mills are ideal for passage and circulation process as well. The circulation process can achieve fineness under 5u. Applications Paints and inks, Pigments and Dyestuffs, Cosmetics, Food processing, Pharmaceuticals, Electronics materials and other medium to high viscosity liquid materials.
