Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, in particular to a ball mill for manufacturing sanitary ceramics. Background Art

[0002] A grinder is used when grinding ceramics. The ceramic ball mill is a key equipment for crushing materials after they are broken. It is widely used in production industries such as ceramics, cement and mineral processing. When the ceramic ball mill is working, its cylinder rotates, and drives the materials and grinding balls in the cylinder to rotate to form a drop impact motion. The block materials are made into powder by the mutual impact and friction between the grinding balls and the materials.

[0003] After searching, the utility model with Chinese patent announcement number CN213468037U discloses a ball mill for ceramic manufacturing, which relates to the field of ceramic manufacturing technology, including a shell, the inner wall of the shell is fixedly connected with a sound insulation layer, the inner wall of the sound insulation layer is fixedly connected with a connecting rod, the inner wall of the sound insulation layer is welded with an inner layer through a set connecting rod, and a vacuum layer is set in the gap between the inner wall of the sound insulation layer and the outer wall of the inner layer. The ball mill for ceramic manufacturing can disperse the materials and clean the dust on the materials while transporting the materials. The dust enters the dust collecting tank through the dust baffle and the leakage net, and the grinding dust is extracted to prevent the dust from flying out, which protects the environment and the health of the workers. The rotating cylinder is connected to the inner layer through a bearing, and there is a vacuum layer between the inner layer and the sound insulation layer. The sound insulation layer is made of sound insulation felt or fiberboard material to reduce the generation of noise. Based on the above search, there is no elastic support component between the inner layer and the shell in the above device. When the grinding ball falls downward, the impact strength on the inner layer is relatively large. If it is not buffered and supported, it will cause damage to the inner layer. Utility Model Content
