鉱山設備ガイド：What Equipment Should You Use for Magnetite, Ilmenite, Coal and Non-Metallic Ore Iron Removal? A Complete Guide to CTB Series Magnetic Separators

The CTB series magnetic separators are suitable for dry and wet magnetic separation of materials such as magnetite, pyrrhotite, roasted ore, and ilmenite with particle sizes of 0.1-3mm. They are also used for iron removal in coal, non-metallic minerals, building materials, and other materials. This equipment utilizes the strong magnetic field generated by the magnetic system to separate magnetic minerals from non-magnetic minerals in the materials or to remove ferromagnetic impurities from the materials. It is an indispensable sorting device in the mining, coal, and building materials industries. Why choose the CTB series magnetic separator? First, it has a high magnetic induction intensity, with the magnetic induction intensity on the cylinder surface reaching 1200-3000GS, effectively separating minerals with different magnetic properties. Second, it has strong adaptability, suitable for both wet and dry magnetic separation, meeting various material and process requirements. Third, it has good separation effects, effectively separating materials such as magnetite, pyrrhotite, roasted ore, and ilmenite, and is also suitable for iron removal in coal, non-metallic minerals, and building materials. Fourth, it comes in a full range of models, with cylinder diameters of 600-1500mm, cylinder lengths of 1200-4000mm, and production capacities of 10-350t/h, meeting the needs of different scales of mining and processing plants. Fifth, it has a reasonable structure, operates smoothly, and is easy to operate and maintain. The CTB series magnetic separators are mainly used for dry and wet magnetic separation of materials such as magnetite, pyrrhotite, roasted ore, and ilmenite; for iron removal in coal, non-metallic minerals, and building materials; and in industrial sectors such as mining plants, coal mines, building material plants, and chemical plants. The groups needing CTB series magnetic separators include mining plants, mining companies, coal mines, building material plants, chemical plants, EPC contractors for mining equipment, maintenance and replacement procurement teams of mining plant equipment, equipment distributors and stockists, and overseas mining project buyers. In what situations should one choose or replace the CTB series magnetic separator? When it is necessary to separate magnetite, pyrrhotite, roasted ore, ilmenite, and other materials; when it is necessary to remove ferromagnetic impurities from coal, non-metallic minerals, building materials, and other materials; when the old magnetic separator has insufficient magnetic induction strength, poor separation results, or a high failure rate and needs upgrading; when new mining or processing plants need to equip efficient magnetic separation equipment; and when export projects require compatibility with overseas voltage and efficient magnetic separation conditions, the CTB series magnetic separator should be prioritized. How to choose a CTB series magnetic separator? Step 1: Confirm the material particle size and magnetism.
