Wet grinding device for hard alloy mixture

Abstract

The invention discloses a wet grinding device for a hard alloy mixture. The wet grinding device comprises a rack, a grinding cylinder, grinding balls, grinding rollers, a feeding device and a discharging device, wherein the rotatable grinding cylinder is arranged on the rack, a first lining and a second lining are arranged in the grinding cylinder, the grinding balls are arranged in the first lining, the grinding rollers are arranged in the second lining, the feeding device is arranged at the feeding end of the grinding cylinder, an annular baffle is arranged at the discharging end of the grinding cylinder, the inner wall diameter of the baffle is larger than that of the second lining and less than that of the first lining, and the discharging device is arranged on the outer side of the baffle. According to the wet grinding device, the first lining and the second lining are arranged in the grinding cylinder, and the grinding balls and the grinding rollers are arranged in the first lining and the second lining respectively, so that the fine crushing degree of raw materials can be further improved, the raw materials can be fully ground, and meanwhile, the contact area between the grinding rollers and the materials can be increased, the grinding of the materials is more sufficient, and due to the fact that the grinding rollers rotate along with the grinding cylinder, the raw material adhesion condition can be effectively avoided.

Description

technical field [0001] The invention relates to the field of cemented carbide cutting tool processing equipment, in particular to a cemented carbide mixture wet grinding device. Background technique [0002] When the cemented carbide tool is produced, the powder of various raw materials is extruded into the shape of a hard tool, and after sintering, it is made by sandblasting and grinding. When the raw material is processed into powder, it needs to be ground. There are two types of dry grinding and wet grinding. The noise of dry grinding is large, and the raw materials are easy to drift, while the noise of wet grinding is small, and the raw materials are in a fluid state after grinding, and the raw materials are not easy to drift. Therefore, in the processing of existing cemented carbide tools, Mostly wet grinding is used. However, due to the fact that the raw material is in a fluid state in the existing wet grinding, the raw material cannot be sufficiently ground, and it i...

Problems solved by technology

However, due to the fact that the raw material is in a fluid state in the existing wet grinding, the raw material cannot be sufficiently ground, and it is easy to adhere to the abrasive tool, resulting in the loss of the raw material. The existing solution is to add enough liquid, but the raw material after wet grinding needs Drying to make it powdery, adding a large amount of liquid will increase the production cost of the entire grinding process, so a wet grinding device that ensures that the raw materials can be fully ground and can prevent the raw materials from adhering is needed
