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
1.Welding materials
In Welding, substances called filler materials or consumables are used. As the name implies, these substances provide filler or a body of molten materials that provides a strong bond to be formed between the base metals used. Most welding processes will also require some form of shielding to protect both the main components and filler from being oxidized during the process.
The type of welding materials used during welding depends on the nature of the job intended. Electrodes draw the necessary energy in order to perform welding applications. Luoyang Golden Egret Company has any kind of welding materials include CTC Welding Rod /rope, SCTC welding rod/rope, TC electronic welding rod, Ni-based welding rod, flux-cored Welding Wires, solid welding wires and etc.
Welding can be applied in different kinds of industries such as building and construction, oil and gas, marine, power generation, steel, mine tools, automobile, transportation and etc.
