Silicon carbide particle shaping device

Abstract

The invention discloses a shaping device for silicon carbide particles. The shaping device is provided with a shaping frame; a grinding plate is arranged on the shaping frame; a main shaft which is vertically arranged is arranged in the grinding plate; the upper end of the main shaft is connected with the shaping frame through a main bearing; the lower end of the main shaft passes through the grinding plate and is connected with a lower bearing arranged on the shaping frame; a plurality of grinding wheels which are matched with the plate bottom of the grinding plate are uniformly arranged in the grinding plate in the circumferential direction of the main shaft; silicon carbide shaping gaps are formed between the bottoms of the grinding wheels and the bottom of the grinding plate; a wheel shaft supporting mechanism for a wheel shaft of each grinding wheel is arranged on the lower part of the main shaft; and a regulating mechanism for regulating height of the silicon carbide shaping gaps is arranged on the main shaft. According to the shaping device disclosed by the invention, the silicon carbide particles with irregular shapes are added into the grinding plate, and the grinding wheels are driven by the main shaft to rotate in the circumferential direction of the main shaft, so that the grinding wheels per se rotate to extrude and grind the silicon carbide particles with irregular shapes, and the diameters and the sharpness of the silicon carbide particles are reduced, and therefore, the shaping device is suitable for the industry with high requirements on silicon carbide for sintering high-grade ceramics and the like.

Description

technical field [0001] The invention relates to a silicon carbide processing device, in particular to a silicon carbide particle shaping device. Background technique [0002] At present, in the production of silicon carbide micropowder, most enterprises are directly packaging the silicon carbide particles into finished products after being crushed by a pulverizer to obtain the micropowder. Such silicon carbide particles have edges and corners, which are suitable for the abrasive industry. Due to the low tap density of such products, the performance of silicon carbide micropowder in the silicon carbide product industry is affected, especially for industries such as high-grade ceramic firing with a high bulk density of silicon carbide. [0003] Due to the high hardness of silicon carbide particles, it is difficult to wear and tear. Some silicon carbide manufacturers use jet mills to shape silicon carbide particles. The output after powder shaping is difficult to meet the spec...

Problems solved by technology

[0003] Due to the high hardness of silicon carbide particles, it is difficult to wear and tear. Some silicon carbide manufacturers use jet mills to shape silicon carbide particles. The output after micro-powder shaping is difficult to meet the specific gravity requirements of customers. At the same time, when air shaping is used, the unqualified silicon carbide micro-powder is generally refilled into the jet mill for shaping. The shaping process is a continuous production process, and the shaping process is difficult. Control, silicon carbide particles with different specific gravity cannot be obtained according to customer requirements, the flexibility of the device is poor, and the investment of jet mill is large, and the cost of manufacturing products with high energy consumption is high
