Main equipment and introduction of mineral processing
I. Ore crushing equipment Jaw crusher Jaw Crusher working principle: Jaw Crusher (Jaw Crusher) has the characteristics of large crushing ratio, uniform product size, simple structure, reliable work, easy maintenance and economical operation. Common electrical equipment for jaw crusher: soft starter, low voltage electrical appliance (contactor, circuit breaker, etc.) Hammer crusher Hammer crusher working principle: Hammer crusher is metallurgy, building materials, chemicals and utilities and other industrial sectors crushing limestone, one of the main equipment of coal or other medium hardness brittle materials, with a crushing ratio, high production capacity, The product has a uniform particle size. Common electrical equipment for hammer crusher: soft starter, low voltage electrical appliance (contactor, circuit breaker, etc.), electromagnetic coupler, hydraulic coupler Second, grinding process equipment Ball mill The working principle of the ball mill : the material is smoothly inserted into the first chamber of the mill by the feeding device through the hollow shaft of the feed. The chamber has a step liner or a corrugated liner, which is filled with steel balls of different specifications, and the cylinder is conveyed to generate centrifugal force. The ball is dropped to a certain height and then falls, which causes heavy impact and grinding on the material. Common electrical equipment for ball mill: Low-voltage electrical appliances (contactors, circuit breakers, etc.), reducers, high-voltage motors, water resistors Spiral classifier Working principle of spiral classifier: The spiral classifier is based on the principle that the solid particle size is different and the specific gravity is different, so the sedimentation speed in the liquid is different. The fine ore particles float in the water and overflow, and the coarse ore particles sink to the bottom of the tank. Common electrical equipment for spiral classifiers: low-voltage electrical appliances (contactors, circuit breakers, etc.), reducers, electric motors Third, the selection process equipment Flotation machine Working principle of flotation machine: When the flotation machine is working, the impeller rotates by the motor drive to generate centrifugal force to form negative pressure. On the one hand, the air is mixed with the slurry, on the one hand, the slurry is mixed with the drug, and the foam is refined. Above the mineral-bonded foam, float to the pulp surface to form a mineralized foam. Common electrical equipment for flotation machines: low-voltage electrical appliances (contactors, circuit breakers, etc.), reducers, electric motors Magnetic separator Working principle of magnetic separator: The magnetic separation process is sorted by the action of magnetic force and mechanical force on the ore particles in the magnetic field of the magnetic separator. Common electrical equipment for magnetic separator: low-voltage electrical appliances (contactors, circuit breakers, etc.), reducers, motors Hybrid Stepper Motors Sts 86Hd,Nema11 Stepping Motor,Connector Step Motor,Quiet Stepper Motor Changzhou Xingchi Electric Co., Ltd. , https://www.starsmotion.com
