Description
Technical Field
[0001] This utility model relates to the field of white fused alumina production and processing technology, specifically to a fine grinding device for white fused alumina production and processing. Background Technology
[0002] White fused alumina is a type of artificial abrasive. It contains over 99% aluminum oxide and small amounts of iron oxide and silicon oxide, giving it a white color. Made from industrial alumina powder, it is produced by melting and cooling at temperatures above 2000 degrees Celsius in an electric arc. After crushing, shaping, magnetic separation to remove iron, and sieving into various particle sizes, it has a dense texture, high hardness, and sharp-angled particle shape. It is suitable for manufacturing ceramics, resin-bonded abrasives, as well as for grinding, polishing, sandblasting, and precision casting (specifically for precision casting). White fused alumina abrasive is suitable for surface finishing of various high-end products, crafts, and hardware. After sandblasting, the surface is clean and free of impurities, eliminating the need for cleaning. The production process of white fused alumina requires ball milling.
[0003] Currently, existing ball milling equipment used for the production and processing of ultrafine white fused alumina powder uses a rotating grinding cylinder to lift the raw material and grinding balls to a high position during grinding. The raw material then falls under the action of gravity and collides with each other, thereby completing the crushing of the raw material. However, traditional ball mills are difficult to meet the grinding requirements for ultrafine white fused alumina powder.
[0004] Therefore, in response to the above problems, we propose a fine grinding device for the production and processing of white fused alumina to solve the aforementioned issues. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fine grinding device for white fused alumina production and processing that is easy to use and improves the grinding efficiency of white fused alumina.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a fine grinding device for white fused alumina production and processing, comprising a fine grinding table, a support base symmetrically arranged on the upper surface of the fine grinding table, a first bearing arranged on the upper end of the support base, a feed pipe arranged inside the first bearing, the feed pipe connected to a soundproof fine grinding box, a fine grinding mechanism arranged inside the soundproof fine grinding box, a discharge port arranged at the lower end of the fine grinding mechanism, a collection box arranged between the fine grinding tables corresponding to the lower end of the discharge port, a drive shaft arranged in the middle of the inner side of the fine grinding mechanism, a grinding cylinder arranged in the middle of the drive shaft, a first grinding disc and a second grinding disc symmetrically arranged on the left and right sides of the grinding cylinder, symmetrical guide discs arranged on both sides of the drive shaft inside the fine grinding mechanism, and a plurality of grinding balls arranged inside the fine grinding mechanism.
[0007] Preferably, the grinding table is fitted with rollers in the middle of the collection box, and the collection box is slidably mounted on the grinding table via the rollers.
[0008] Preferably, the feed pipe is provided with a feed inlet, which is located at the front end of the fine grinding mechanism. A limit block is provided at the front end of the fine grinding mechanism, and the limit block is fixed to the inner wall of the feed pipe.

[0010] Preferably, the drive shaft is provided with a second bearing on the support base, and a limiting seat is provided on the support base at the front end of the second bearing.

[0012] Preferably, the guide plate is provided with guide blades, and the first grinding plate, the second grinding plate and the grinding cylinder are each provided with a plurality of grinding holes. Four fixing columns are cross-fixed on the transmission shaft in the middle of the grinding cylinder. Each fixing column includes a stirring shaft at the top and a semi-circular fixing plate in the middle.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses symmetrically arranged support seats on the upper part of the fine grinding table to set up a soundproof fine grinding box. The soundproof fine grinding box grinds the white corundum raw material through the fine grinding mechanism inside. The soundproof fine grinding box plays a role in sound insulation and noise reduction during the operation of the fine grinding device, and also serves to collect the ground white corundum. The feed port set at the front end of the fine grinding mechanism allows the material to be fed into the fine grinding mechanism through the feed pipe. The drive motor drives the guide plate, the first grinding plate, the second grinding plate and the grinding cylinder inside the fine grinding mechanism to rotate at high speed through the transmission shaft, and also drives the fine grinding machine. The structure rotates at low speed, while the guide discs on both sides of the drive shaft guide and stir the white fused alumina raw material and grinding balls. Then, the white fused alumina raw material is ground by the first grinding disc, the second grinding disc, and the grinding cylinder set in the middle of the fine grinding mechanism. The grinding balls work in conjunction with the above-mentioned grinding device to improve the grinding efficiency. At the same time, the grinding method of the guide disc, the first grinding disc, the second grinding disc, and the grinding cylinder can realize multi-stage and multi-position grinding of white fused alumina raw material, which can effectively improve the grinding fineness and comprehensiveness of white fused alumina raw material, making its grinding effect better, and can also meet the grinding requirements for the production and processing of ultra-fine white fused alumina powder.
