Description

High wear-resisting raw material grinding device

Technical Field

The utility model relates to a grinding device technical field specifically is a high wear-resisting raw material grinding device.

Background

In recent years, the novel dry cement production technology in China is rapidly developed, the technology and equipment level of the vertical mill are improved, a part of cement enterprises use the vertical mill, and the vertical mill manufactured by manufacturers at home and abroad is put into production to obtain a good energy-saving effect. The vertical mill used in cement industry can grind coal powder, cement raw material, cement slag converter slag powder and pre-crushed clinker. The vertical mill for grinding products can be classified into four types, i.e., a coal mill, a raw mill, a cement mill and a slag mill. The vertical mill structure has various forms due to the difference of granularity, moisture, form and grindability of the ground materials and the different technical requirements of products. When the vertical mill is in use, the wearing parts of the vertical mill are abraded by materials, such as a grinding disc, a grinding roller, a nozzle ring, a fan blade and the like, wherein the most serious condition is that the surfaces of the grinding disc and the grinding roller are worn and failed. When the grinding rollers and the grinding discs of the vertical mill are worn too heavily, the yield is reduced, and the reduction of the yield means the waste of energy.

The vertical mill mainly comprises a grinding roller, a grinding disc, a separator, a pressurizing device, a speed reducer, a motor, a shell and the like, and the working principle of the vertical mill is to grind materials by a rolling principle. When the grinding roller moves on the grinding disc along a horizontal circular track during operation, the materials on the grinding disc are crushed under the extrusion and shearing actions through the vertical pressure externally applied to the grinding roller. The grinding roller and the grinding disc of the vertical mill are key easily-damaged wear-resistant parts of the vertical mill, and the quality of the grinding roller and the grinding disc of the vertical mill is directly related to the yield, the quality and the operation cost of a vertical mill unit.

Go into to grind the raw materials and can form the vortex on falling the mill center apron, raw materials and mill center apron relative rotation can lead to mill center apron wearing and tearing to become the donut shape, can lead to the mill to wear when serious, causes the risk of founding the mill and shutting down, and the apron wearing and tearing back material can drop in the founding mill centre frame simultaneously, and the maintenance degree of difficulty is great, and the time is longer.
