Description

Technical Field

[0001] The utility model relates to the technical field of metal powder making equipment, in particular to a ferroalloy powder making machine. Background Art

[0002] At present, the method of mechanically pulverizing metals is usually to grind the metal particles through a grinder into a powder with a particle size of -100 to -200 mesh. There are various types of grinding equipment. After long-term use, the existing metal pulverizing machines cause great vibrations to the various structural components due to the processing of metal block materials, which makes them poorly sealed and easily produces gaps, which in turn causes the powder material to leak out, and the structural components of the equipment are also easily damaged under large impacts. In addition, when the metal pulverizing machine is running at high speed, the bearing components are easily damaged when working at high temperatures and have a short lifespan. Due to defects in the design of the grinding structure, some pulverizing machines cannot effectively grind metal materials, reducing the effect of grinding and pulverizing. Utility Model Content
