Description

Technical Field

[0001] The utility model relates to the technical field of vanadium-nitrogen alloys, in particular to a crushing device for processing vanadium-nitrogen alloys. Background Art

[0002] Vanadium-nitrogen alloy is a new type of alloy additive that can replace ferrovanadium in the production of micro-alloyed steel. Adding vanadium nitride to steel can improve the comprehensive mechanical properties of steel such as strength, toughness, ductility and thermal fatigue resistance, and make the steel have good weldability. During the processing of vanadium-nitrogen alloy, it needs to be crushed.

[0003] The utility model with application number CN202121260403.1 discloses a crushing device for vanadium nitrogen alloy processing. The material falling into the main body of the device through the feed box will be squeezed and crushed by the first crushing roller and the second crushing roller, and then the crushed material will fall on the filter plate, and the small particles in the crushed material will pass through the filter plate and fall into the first collection box, and the large particles in the crushed material will roll on the filter plate and then fall into the second collection box, so that the classification operation of the crushed material can be realized.

[0004] The above device classifies large and small particles after the vanadium-nitrogen alloy is crushed by a filter plate. After classification, the large particles need to be manually poured into the feed box for secondary crushing. The vanadium-nitrogen alloy is toxic. The operator's long-term contact with the vanadium-nitrogen alloy affects the health of the staff. Manual loading is labor-intensive and inefficient.

[0005] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Utility Model Content
