Description

Technical Field

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

[0002] The ceramic ball device of ball mill is a mechanical equipment used to prepare powder materials. It usually consists of ceramic balls and a ball mill host. Ceramic balls are a hard, wear-resistant ball milling medium that can rotate with the material in the ball mill to grind and mix the material. Ceramic balls are generally made of high-purity ceramic materials, such as alumina or silicate. They have the characteristics of high hardness, wear resistance, and corrosion resistance, and can effectively grind and mix various materials. The ball mill host is the core component of the ball mill. It drives the ceramic balls to rotate through a motor to achieve grinding and mixing of materials. The ceramic ball device of ball mill is widely used in ceramics, chemicals, building materials, metallurgy and other industries to grind various materials, such as ore, quartz sand, cement, ceramic powder, etc. It has the advantages of high grinding efficiency, low energy consumption, and uniform product particle size, and is widely used in material grinding and mixing processes in the production process.

[0003] During the use of the ball mill, the ceramic balls need to be maintained regularly, so the ceramic balls need to be taken out of the ball mill. However, when taking out the balls, some existing ball mills generally open the maintenance port and then rotate the ball mill to throw the ceramic balls out of the ball mill. However, because the force of the throwing cannot be controlled, the ceramic balls may be damaged secondary during the throwing process, so this problem needs to be solved. Utility Model Content
