The horizontal mill is micro disperser of horizontal wetting continuously production, it is easy to operate and highly mill efficiency. The operation is put the materials and grinding medium (the diameter is 3/32″~3/32″) into static grinding vat with jacket, the mixing arm and the dispersing blade high-speed rotation to offer enough momentum to the grinding medium, and the high-speed rotating medium give a shear force and shock, so can get the best dispersing and grinding effect. The special-designed two speed pneumatic motor away from the edge, no need the coupling. When charging and discharging we put low speed and when grinding put high speed. The special disengaging gear, discharge the material and medium, can realize large scale continuous production, advance the quality of the production and reduce the cost.
