Description

Technical Field

[0001] The utility model relates to the technical field of manganese alloy grinding equipment, in particular to a grinding device for preparing manganese alloy powder. Background Art

[0002] After production, manganese alloy itself is in block form and cannot be directly used as an additive in steel production. The manganese alloy needs to be ground into powder to facilitate the addition of manganese alloy powder during the steel production process. For example, a silicon-manganese alloy production solid waste crusher disclosed in Chinese patent literature (patent number: CN202222854856.8) crushes the manganese alloy with blades. The rotation of multiple sets of blades can only crush the manganese alloy into smaller particles, and cannot directly crush the manganese alloy into powder. When the volume of the manganese alloy is large, it is easy to get stuck in the blades, affecting the operation of the device.

[0003] To this end, we propose a grinding device for preparing manganese alloy powder Utility Model Content
