Description

Technical Field

[0001] The invention relates to the technical field of aluminum-vanadium alloy grinding, in particular to a rough crushing and grinding device for aerospace-grade aluminum-vanadium alloy. Background Art

[0002] In actual aluminum-vanadium alloy processing work, grinding work for aluminum-vanadium alloy raw materials is often involved. It is necessary to refine large aluminum-vanadium alloy particles. The aluminum-vanadium alloy particles obtained by coarse crushing and grinding are widely used in aerospace, automobile and other fields. In order to ensure grinding efficiency, the current aluminum-vanadium alloy grinding mostly adopts ball mill batch processing, which is widely used due to its large production batch and other advantages. The current aluminum-vanadium alloy coarse crushing and grinding ball mill relies on the gravity of grinding steel balls for crushing and grinding, which has limited improvement in grinding efficiency, is not convenient for electromagnetic control pressurized grinding, and has poor grinding and crushing impact force performance. Grinding thicker particles is likely to lead to poor grinding impact effect of the bottom layer, which is not convenient for anti-sticking grinding. Long-term impact grinding can easily lead to a large amount of small-particle aluminum-vanadium alloy powder adhering to the inner wall of the ball mill barrel, causing waste and affecting the subsequent impact grinding effect. It is not convenient to use wind power for automatic discharge, and small-particle aluminum-vanadium alloy particles are prone to continuous over-grinding. Summary of the invention
