Description

Technical Field

[0001] The utility model relates to the technical field of molybdenum ore processing equipment, in particular to a molybdenum ore crusher with a magnetic separation function. Background Technique

[0002] Molybdenum ore refers to the ore containing molybdenum element. Molybdenum ore has a wide range of uses in industry, mainly because molybdenum metal has excellent properties such as high strength, high melting point, corrosion resistance, and wear resistance. In the metallurgical industry, molybdenum is commonly used as an additive for producing various alloy steels. Molybdenum-containing alloy steels are widely used in manufacturing transportation devices, locomotives, industrial machinery, and various instruments;

[0003] In the process of molybdenum ore mining and processing, it is usually necessary to use a molybdenum ore crusher with a magnetic separation function to perform magnetic separation and purification on the magnetic minerals contained in the molybdenum ore. During the working process of the molybdenum ore crusher with a magnetic separation function, usually, a driving device drives two groups of crushing rollers to rotate. When the molybdenum ore passes through the gap between the two groups of crushing rollers, it is subjected to the extrusion and shearing action of the crushing rollers, so as to be broken into smaller molybdenum ore particles. Then, the driving device drives the magnetic separation roller to rotate. During the rotation of the magnetic separation roller, the magnetic minerals in the molybdenum ore particles are adsorbed. When the magnetic minerals contact the scraper, the magnetic minerals are scraped off by the scraper, and finally discharged through the discharge port;

[0004] In the process of using the existing molybdenum ore crusher with a magnetic separation function, although it can perform magnetic separation and purification on magnetic minerals through the magnetic separation roller, the position of the magnetic separation roller is fixed, resulting in a limited contact area between the magnetic separation roller and the molybdenum ore particles. Some molybdenum ore particles containing magnetic minerals will accumulate at the bottom of the box, affecting the magnetic separation effect. Some molybdenum ore crushers with a magnetic separation function use stirring fan blades to lift the molybdenum ore particles, thereby increasing the contact area between the molybdenum ore particles and the magnetic separation roller. However, due to the limited coverage area of the stirring fan blades, the lifting effect is poor, and the amount of molybdenum ore particles lifted each time is relatively small, thus reducing the magnetic separation efficiency. For this reason, we propose a molybdenum ore crusher with a magnetic separation function. Summary of the Utility Model
