Design principle of sand mill;

The sand grinder adopts eccentric disc grinding structure and is arranged in a certain order. The system overcomes the disadvantage of uneven distribution of grinding media in traditional mills, and makes the grinding media obtain the maximum energy transfer. High grinding efficiency. The mechanical seal with forced cooling at both ends is adopted, which has good sealing effect and reliable operation. The separation system adopts large-flow LDC dynamic grid gap separator, which will not block the discharge port under the condition of large flow, and the overflow area is 0.05-2.0 mm

The NHE horizontal disc sander adopts the closed design of eccentric disc grinding cavity, and the grinding discs are installed on the mixing shaft in a certain order, which overcomes the shortcomings of uneven distribution of grinding media and poor particle size distribution after grinding in the traditional horizontal sand grinder. The material enters the grinding cavity under the action of the feed pump, and the inlet is designed at one end of the drive connecting flange, and the flow direction of the material and the mechanical bearing is opposite to the bottom end, which greatly reduces the bearing pressure of the mechanical seal and prolongs its service life. In the high-speed operation of the eccentric disc of the stirring shaft, the mixture of material and grinding medium moves relatively effectively. So that the solid particles of the material can be effectively dispersed, sheared and ground, and the final product can be obtained after the filter is separated through the dynamic large-flow rotor gap. According to the different grinding processes of products, independent batch circulating grinding and series grinding processes can be adopted.
