The working principle of the roller magnetic separator ‌is to realize the separation of minerals through the combined action of magnetic force and gravity. Specifically, materials containing magnetic substances are evenly distributed on the belt of the magnetic separator, and these materials enter the magnetic field area with the belt. Under the action of strong magnetic field, the magnetic material is quickly adsorbed to the surface of the magnetic roller, and is taken away from the magnetic field area with the movement of the belt, and finally falls into the magnetic material collector. The non-magnetic materials and magnetic impurities that are not completely adsorbed will be separated from the magnetic field under the continuous rotation of the belt by gravity and fall to the next layer of the belt or directly discharged, so as to realize the effective separation of magnetic and non-magnetic materials.

Structural composition

Roller magnetic separator mainly consists of the following parts:

‌Extrusion rolling: used for uniform distribution and crushing of large grained ore.

‌Feed belt: clockwise operation, located at the top, for transporting ore.

‌Concentrate belt: located under the feed belt, used for conveying materials with magnetic minerals adsorbed.

‌Overflow belt: located in the front of the feed leather lead wheel, plays an auxiliary sorting role.

‌Fine tailings regulator: used to control the separation of concentrate and tailings.

‌Concentrate tank ‌, ‌tailings tank ‌, ‌overflow concentrate tank: used for collecting concentrate, tailings and overflow concentrate respectively.

Technical advantages and application scope

Technical advantages of roller magnetic separator include:

High magnetic field strength: The use of high-performance magnetic materials and unique magnetic pole design, can produce up to thousands of gauss magnetic field strength, to ensure the rapid and accurate separation of minerals.

‌High efficiency separation: by adjusting the position of fine tailings regulation plate, the separation amount of concentrate and tailings can be accurately controlled, and the separation efficiency.

Roller magnetic separator is mainly used for separating iron ore from crushed iron ore. It has been applied on the ground in various places, showing good separation effect and wide application prospects
