Millstone type natural graphite fine grinding and screening device

Abstract

The invention discloses a millstone type natural graphite fine grinding and screening device. The millstone type natural graphite fine grinding and screening device comprises a base, a grinding box, agrinding box screen net, a second drive motor and a material collecting box. A grinding cavity is internally provided with a fixed millstone. A main shaft is fixedly provided with a movable grindinghead, and the movable grinding head is located below the fixed millstone. The left inner wall and the right inner wall of the grinding box are obliquely provided with a first clamping groove and a second clamping groove correspondingly. The screen net is installed between the first clamping groove and the second clamping groove in a sliding manner. The movable grinding head rotates to grind graphite particles, compared with an existing grinding manner, the grinding effect of the movable grinding head is better, and the fine degrees of ground particles are higher; and by means of horizontal movement of a horizontally moving block, the screen net is indirectly driven to slide between the first clamping groove and the second clamping groove, the screening speed of the ground graphite particles is greatly increased, meanwhile, the screen net is obliquely arranged, the flowing rate of the graphite particles on the screen net is further increased, the situation that holes are blocked by thegraphite particles is effectively avoided, and the screen net cleaning frequency is reduced.

Description

technical field [0001] The invention relates to a grinding device, in particular to a disc-type natural graphite fine grinding and screening device. Background technique [0002] Graphite and carbon products have excellent performance and are widely used, and the production capacity and benefits are showing a rapid growth trend. In 2011, China's graphite and carbon products industry developed rapidly, and enterprises in the industry had a relatively high ability to manage and control costs and strong profitability. According to the data of the National Bureau of Statistics, in 2011, my country's graphite and carbon products industry achieved a total industrial output value of 167.564 billion yuan; realized sales revenue of 167.765 billion yuan, a year-on-year increase of 40.58%; realized a total profit of 10.959 billion yuan, a year-on-year increase of 50.87%. With the continuous promotion of applications, the competition in China's graphite and carbon products industry is ...

AI Technical Summary

Problems solved by technology

[0003] At present, the graphite particle grinding device consists of two sets of grinding wheels that squeeze the graphite particles mutually, and the current graphite particle grinding device has a large gap between the grinding wheel and the inner wall of the grinding box, so that part of the graphite particles leaks to the lower part of the graphite particle along the gap. In the material receiving box, the phenomenon of uneven grinding of graphite is caused, resulting in secondary grinding or sieving, which prolongs the processing time and reduces productivity.
