Description

Technical Field

[0001] The utility model belongs to the technical field of ceramic production equipment, in particular to a ball milling device for ceramic production. Background Art

[0002] The ceramic production process includes multiple steps. First, the raw materials are prepared. Raw materials such as clay, quartz, and feldspar are selected and pre-treated. Then the ingredients are mixed. Next, the mixed raw materials are placed in a ball mill and ground with grinding media and water. After ball milling, they are sieved and iron removed. Then the mud is prepared and additives are added to improve the performance. After that, the raw materials are formed through grouting, pressing, extrusion, etc. The formed body is dried and then placed in a kiln for firing. The temperature and time are controlled according to product requirements. After firing, post-processing such as grinding, polishing, and glazing is carried out.

[0003] For some small and medium-sized ceramic production enterprises, during the ball milling process, the ground mud often needs to be scooped out and sieved manually, resulting in low mud processing efficiency. During screening, the mud needs to be pressed manually to ensure smooth screening, resulting in higher work intensity for workers and higher labor costs for the enterprise. Utility Model Content
