Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to a ball mill which is convenient for fast material discharging. Background Art

[0002] In the process of paint production, a large amount of powder needs to be pre-dispersed and ground and dispersed. The pre-dispersion first mixes the pigment with part of the color paint to obtain a mixed color paste, and then the mixed color paste is fully dispersed through the grinding and dispersing equipment to obtain the pigment paste, and then continue to the next step of processing. At present, the grinding and dispersing processing in the paint production process generally uses a ball mill for grinding and dispersing.

[0003] A Chinese utility model patent with announcement number CN218245182U discloses a ball mill capable of automatic loading. By providing a second motor, a conveyor belt, a baffle, a follower roller, a movable bracket and a connecting frame, the movable bracket and the connecting frame can adjust the inclination angle of the conveyor belt, thereby facilitating the connection between one end of the conveyor belt and the feed port, facilitating the transportation of materials into the feed port, and thus entering the drum for processing. At the same time, the second motor can drive the active roller to rotate, so that the conveyor belt can transport materials under the support of the active roller and the follower roller.
