Description

Technical Field

[0001] The utility model relates to the technical field of air flow mill equipment, in particular to an oblique nozzle air flow mill equipment for high-hardness powder accumulation. Background Art

[0002] The air flow mill is a processing equipment that crushes materials by blowing high-pressure air. The high-pressure air flow is sprayed onto the material inside the lower grinding body through the inclined nozzle installed in the lower grinding body to complete the processing.

[0003] However, the current air flow mill equipment has some shortcomings. The direction of the conventional air flow mill nozzle is horizontal, and there is a blind plate for maintenance at the bottom of the air flow mill equipment, so there is a blind area at the bottom of the mill body that cannot be blown up. High-hardness materials are often difficult to crush during the crushing process, and larger particles are prone to appear. These larger particles are more likely to accumulate at the bottom of the crushing during the fluidization process, resulting in material accumulation at the bottom. The accumulated material will increase the material level in the grinding chamber, resulting in a reduction in the fluidization area, affecting the crushing effect. After accumulation to a certain extent, the bottom material can only be manually disassembled and cleaned, which is very inconvenient. Utility Model Content
