Description

Technical Field

[0001] The utility model relates to the technical field of cement grinding, in particular to a cement grinding device. Background Art

[0002] A cement mill is a key device for further pulverizing materials after they are crushed. Processing machines are widely used in production industries such as cement, silicate products, new building materials, refractories, fertilizers, black and non-ferrous metal beneficiation, and glass ceramics. They are used for dry or wet grinding of various ores and other grindable materials. Processing machines play a very important role in cement production. In the production cost of cement, the power consumption for grinding accounts for 35% - 40% of the cement cost. Cement grinding is the last and most important key link in controlling cement quality. To a certain extent, the grinding quality can make up for the deficiencies in clinker quality and ensure the qualification rate of the cement leaving the factory. With the development of society, when cement needs to be processed, a grinding device is used.

[0003] Existing equipment such as CN221472037U, an improved cement mill, includes a cement mill body. An inlet pipe is provided at the left end of the cement mill body. Two parallel stabilizing sleeves are provided on the outer walls at both ends of the cement mill body. A liquid storage and heat conduction cover is fixedly installed on the side wall surfaces of the two stabilizing sleeves close to each other. A heat conduction plate is fixedly installed between the tops of the two stabilizing sleeves. Auxiliary heat dissipation fans are evenly distributed on the top of the heat conduction plate. A cooling water tank is provided at the top right end of the cement mill body. An inlet pipe and a return pipe are communicated at the left end of the cooling water tank. The other ends of the inlet pipe and the return pipe respectively penetrate through the stabilizing sleeve at the right end and are communicated with the inner cavity of the liquid storage and heat conduction cover. Water in the cavity of the liquid storage and heat conduction cover is used for water-cooling heat dissipation of the cement mill body. A semiconductor cooling sheet in the cooling water tank is used to cooperate with the water in the cavity of the liquid storage and heat conduction cover for cooling. At the same time, air-cooling auxiliary heat dissipation is carried out through the heat conduction plate and the auxiliary heat dissipation fans, effectively improving the heat dissipation effect of the cement mill body.
