Technical Field

[0001] The utility model relates to the technical field of graphite processing equipment, in particular to a homogenizing, crushing and grinding device for graphite processing. Background Art

[0002] Graphite is an allotrope of carbon, a gray-black, opaque solid with stable chemical properties and corrosion resistance. It is not easy to react with acids, alkalis and other agents, and can be used to produce refractory materials, conductive materials, wear-resistant materials, lubricants, high-temperature resistant sealing materials, etc. These materials are widely used in metallurgy, petrochemical industry, machinery industry, electronics industry, nuclear industry and national defense. When producing and processing graphite, the raw materials need to be crushed and ground first.

[0003] To this end, the Chinese utility model authorization announcement CN214515071U discloses an environmentally friendly crushing and grinding device for graphite processing, including a base, a box body is arranged on the upper side of the base, and the bottom of the box body is fixedly connected to the base... The grinding roller and the grinding knife will mesh and rotate under the drive of the gear, so that the graphite raw material can be crushed and rolled strongly and relatively completely, which greatly improves the quality of the crushing and grinding of the graphite raw material.

[0004] The above device has the following shortcomings: when the double-layer grinding is continuously operated, large and small particles will be mixed and affect the homogenization, and the interval operation will affect the efficiency. In addition, when the graphite encounters water vapor during storage and transportation, it will quickly absorb water vapor and form moisture. It needs to go through a separate drying process before it can be put into use, which increases the complexity of the processing process.

[0005] Therefore, we propose a homogenizing, crushing and grinding equipment for graphite processing to solve the above problems. Utility Model Content
