Description

Technical Field

[0001] The utility model belongs to the technical field of graphite electrode processing, and in particular relates to a graphite electrode crushing device. Background Art

[0002] Graphite electrode refers to a high-temperature resistant graphite conductive material made of petroleum coke and asphalt coke as aggregates and coal tar as binder, through raw material calcination, crushing and grinding, batching, kneading, molding, roasting, impregnation, graphitization and mechanical processing. When producing graphite electrodes, it is usually necessary to test the graphite electrode samples first to ensure that the graphite electrodes meet the production standards. The graphite electrodes are added to a grinder for crushing to obtain powdered samples, which are then tested.

[0003] By placing the graphite electrode between two crushing rollers, the graphite electrode can be crushed as the crushing rollers rotate. Since the graphite electrode is crushed in this process, part of the graphite electrode powder will be located on the surface of the roller, affecting the subsequent crushing of the electrode. Some brushes are fitted to the outer wall of the crushing roller to clean the graphite on the outer wall of the crushing roller. This method often requires continuous cleaning in a circular manner, which is more troublesome and affects the use of the crushing device. Utility Model Content
