Description

Technical Field

[0001] The utility model relates to the technical field of ball mill cooling, in particular to a feedback type ball mill cooling mechanism. Background Art

[0002] A ball mill is a device that re-processes the materials after the initial crushing. It can further crush the materials so that the particle size of the materials is small enough to meet the production needs. Ball mills are widely used in a series of social production fields such as cement, silicate products, new building materials, refractory materials, and chemical industries. The main structure of a ball mill is generally a rotating part. The rotating part is the main body of the ball mill. It is a cylinder with wear-resistant parts on the inner surface. There are movable grinding balls in the grinding chamber inside the cylinder. The rotating part rotates around the axis driven by the transmission structure. During production, the rotating part rotates. Driven by centrifugal force, the grinding balls collide and rub against each other, grinding the filling materials in the grinding chamber, thereby achieving the purpose of reducing the size of the materials.
