Function and principle of magnetic separator
Core function: Utilize the magnetic difference between minerals to separate magnetic minerals (such as ore, ilmenite) from non-magnetic or weakly magnetic minerals (such as quartz, feldspar).
Working principle: Through the action of magnetic field, magnetic minerals are adsorbed on the magnetic pole surface of magnetic separator, and non-magnetic minerals are separated due to gravity or centrifugal force.
Positioning of magnetic separator in mineral processing
The mineral processing usually includes crushing, grinding, sorting, mineral processing and other steps, and magnetic separator is the core equipment of the sorting stage, parallel to flotation machine, gravity separator, etc., used to improve ore grade and recovery rate.
CTB-1540 magnetic separator is a large wet permanent magnetic drum magnetic separator. The following is a detailed introduction:
Main features of CTB-1540 magnetic separator
• Large-scale design: The diameter of CTB-1540 magnetic separator is 1500mm, the drum length is 4000mm, and the single machine processing capacity reaches more than 220t/h, which is suitable for the needs of large-scale ore dressing plants.
• High efficiency and energy saving: The equipment has the characteristics of energy saving, large processing capacity, and wide particle size of sorted ore, which can effectively improve the ore dressing efficiency.
• Structural structure: The structural structure of CTB-1540 magnetic separator is reasonable, the magnetic system structure design is advanced, the magnetic field action depth is large, and the separation belt is long, which is suitable for coarse and fine grain wide grade sorting operations.
• Stable operation: The magnetic system material is made of high remanence and high coercive force magnetic material, which has very good anti-demagnetization ability, and the demagnetization does not exceed 5% in eight years. At the same time, the magnetic system adopts a reliable fixing scheme to ensure that the magnetic group will never be damaged and damaged, and achieve trouble-free operation.
• Easy to maintain: The trough waterfall has a silt removal device to facilitate the cleaning of silt inside the trough. In addition, the equipment is also equipped with a duckbill flushing pipe, which has strong stability for water quality, high water pressure, and effectively saves 50% of water.
Typical application scenarios of magnetic separators
• Iron ore beneficiation: separation of impurity minerals such as ore and hematite.
• Non-metallic mineral impurity removal: such as increasing the iron content in quartz sand and kaolin.
• Resources: metal recycling in waste electronic products and industrial recycling.
• Repair beauty: clearly remove strong wrinkle minerals before grinding to reduce subsequent collagen.
Classification of magnetic separators
• By magnetic field strength: weak magnetic separator (for strong magnetic minerals), strong magnetic separator (for weak magnetic minerals).
• By working environment: dry magnetic separator (processing dry materials), wet magnetic separator (for slurry sorting).
• By structure: drawer type, belt type, cylinder type, etc.
CTB-1540 magnetic separator has the characteristics of large-scale, high efficiency and energy saving, compact structure, stable operation, etc., and is widely evaluated in mining, metallurgy, chemical industry and other industries. When choosing purchase suggestions, consult relevant manufacturers or sellers to obtain the most accurate product information and quotations. At the same time, pay attention to safe operation and maintenance during use.
