Description

Technical Field

[0001] This utility model belongs to the field of air classifier technology, specifically relating to a mining air classifier. Background Technology

[0002] Air classifiers are key grading equipment in the powder processing field. They separate materials of different particle sizes through principles such as airflow and gravity, and are widely used in industries such as building materials and mining. Their core function is to separate qualified finished products from coarse materials that need reprocessing. Among them, the non-powered air classifier is a low-cost and easy-to-operate type. It does not require a motor drive and relies on the material's own weight and airflow adsorption to separate fine powder. It is suitable for cleaning dust from manufactured sand and coarse aggregates in mining, and can efficiently separate dust from 0-8mm sand and gravel, helping mines improve aggregate quality. It is a practical piece of equipment in the coarse material processing stage of mining.

[0003] In the operation of a non-powered air classifier, the powder falls inside the machine and collides with the internal impact bars, thereby breaking up the powder and facilitating subsequent screening and air separation. After long-term use, the impact bars will suffer severe wear or even deformation, reducing the powder classification effect. However, it is inconvenient to disassemble and replace the internal impact bars in existing air classifiers. Therefore, a new air classifier needs to be designed to solve this problem.
