Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, in particular to a lime raw material ball mill used for producing autoclaved sand aerated concrete blocks. Background Art

[0002] Autoclaved sand aerated concrete blocks are suitable for internal and external filling walls above the ground and internal filling walls below the ground of various buildings. They have the characteristics of light weight, good thermal insulation, strong seismic resistance, good processing performance, good sound insulation, strong adaptability, and good fire prevention. During the production process, the lime raw materials need to be ground and evenly ground into finer particles. Therefore, a ball mill is needed to process the lime raw materials.

[0003] According to the description of a ball mill for lime raw material pretreatment disclosed in the patent website (authorization announcement number: CN217962767U), "the utility model belongs to the technical field of ball mills, and discloses a ball mill for lime raw material pretreatment, including a cylinder, a bracket is installed at the bottom of the cylinder, and one end of the cylinder is connected to a feeding device, and the other end is connected to a discharging device. A gear ring is installed on the side of the cylinder close to the discharging device, and a lining plate is fixedly connected to the inner wall of the cylinder. A partition plate is arranged inside the cylinder, and a number of grinding bodies are arranged on both sides of the partition plate, and a sound insulation layer is arranged on the outer side of the cylinder. The utility model adopts a rubber lining plate instead of a manganese steel lining plate. Due to the high elasticity of rubber, it can be deformed when subjected to the impact of the grinding body, thereby reducing the force on the cylinder and reducing the noise. In addition, the sound insulation layer arranged on the outside of the cylinder can adopt glass wool sound-absorbing material, and the outer side of the sound-absorbing material is covered with a rubber plate, and a galvanized thin steel plate or a metal aluminum plate is wrapped on the outside. It is both beautiful and can play a single-layer sound insulation role."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model can reduce grinding noise and avoid the possibility of deformation of the cylinder due to impact through the rubber lining, and can allow materials to enter the sampling ring through the sampling ring through the expansion and contraction of the electric steel. However, in actual use, when the device transports the raw materials to the inside of the cylinder, it directly transports them through the feed screw. If the lime raw materials are not pretreated, larger lime raw materials will be stuck in the feed screw, affecting the transportation of the raw materials. Therefore, it is necessary to improve a lime raw material ball mill for the production of autoclaved sand aerated concrete blocks to solve the above problems. Utility Model Content
