Description

Technical Field

[0001] The utility model belongs to the technical field of grinding, in particular to a mobile grinding system. Background Art

[0002] Existing grinding stations include cement grinding stations and slag grinding stations, most of which are fixed. The site selection principle is based on the proximity of raw materials. Once the raw materials are consumed or the grinding station stops production, the equipment is scrapped and cannot be reused.

[0003] At present, several mobile grinding systems are designed on the market. For example, CN107570302A discloses a mobile grinding station system and process, which adopts modular design installation and disassembly, is easy to transport and install quickly. CN212596304U discloses a mobile cement grinding device, which has the characteristics of small size and convenient mobility. The above devices all achieve the advantages of equipment reuse. CN207546651U discloses a mobile cement grinding station, which uses a cement ball mill for grinding and a powder selector to select finished cement. Because the grinding bodies inside the ball mill collide with each other, there is no cement ball mill for ball grinding, so the effect is not good, and the cement clinker is involved in grinding, which produces useless work and converts useless heat, making the system consume too much energy and the output is also low. The problems existing in the mobile grinding systems on the market are: the types of materials include dry materials and wet materials, which need to be dried or watered according to the needs. The mobile cement grinding stations on the market cannot meet the needs at the same time, especially they cannot grind materials such as slag with a high moisture content, so a mobile grinding system needs to be redesigned.
