The invention discloses a self-fastening type ball mill cylinder applied in industries such as power plants, metallurgy, mines, and building materials. The self-fastening type ball mill cylinder comprises a cylinder body, a plurality of liner plates and a plurality of fastening blocks. The liner plates and the fastening blocks are alternately fixed on the cylinder body. When the liner plates are installed, the liner plates are firmly attached to the cylinder body of the ball mill. Only a small amount of fixing bolts for the convenience of detachment is applied. Therefore, the tightness of the cylindrical body is greatly improved, such that the liner plates are completely prevented from falling from the cylinder body due to broken bolts. The maintenance frequency of the ball mill is reduced, the utilization efficiency of the liner plates is sufficiently developed, and the safe and economic operation of the equipment is ensured.
Description
technical field [0001] The invention relates to a ball mill used in industries such as power plants, metallurgy, mines, building materials, etc., in particular to a ball mill barrel. Background technique [0002] At present, ball mills have been widely used in power plants, metallurgy, mining, building materials and other industries. The existing liners for ball mill cylinders are usually symmetrical wave-shaped, wave-shaped, tooth-shaped corrugated, trapezoidal corrugated and other liners. The surface shape of the fixed surface is usually a curved surface that matches the surface shape of the inner surface of the cylinder. When the material is ground by the grinding body in the cylinder, the grinding body and the material roll from one end of the liner to the other end. However, because most of the current ball mills use bolts to fix the liner, the bolts will inevitably break and loosen during high-strength impact operation. Loosening or breaking of bolts will cause powder...
