Description

Technical Field

[0001] The utility model relates to the technical field of vertical mill equipment, in particular to a vertical mill water spraying device. Background Art

[0002] Vertical mills are now widely used in cement plants and grinding plants for grinding raw materials, clinker, slag, etc. They are highly efficient and energy-saving industrial equipment with good economic benefits and energy-saving effects. When the raw materials are dry or the grinding rollers are worn out, and the raw material bite decreases, water needs to be added to the raw materials that are rotated and ground by the grinding rollers and grinding discs.

[0003] In the prior art, the vertical mill water spray device does not have an angle adjustment function and has a blind spot, which causes the applied water to be unable to be evenly dispersed on the friction surface between the grinding roller and the grinding disc by centrifugal force, resulting in the product being unqualified in quality due to lack of water during the production grinding process, and the grinding roller and the grinding disc often slip, affecting production. In severe cases, the grinding roller and the grinding disc may be damaged. Therefore, a vertical mill water spray device is proposed.
