Flat magnetic separator

Overview

Flat magnetic separator is a magnetic separation equipment used for sorting magnetic materials, widely used in industries such as mining, metallurgy, building materials, and chemical engineering. It is mainly used to separate ferromagnetic substances (such as magnetite, ilmenite, manganese ore, etc.) from non-magnetic materials or remove iron impurities from raw materials.

1. Magnetic structure:

The core component of a flat magnetic separator is the built-in permanent magnet system, which usually uses high-strength neodymium iron boron magnetic blocks arranged in a specific magnetic circuit to form a high-intensity magnetic field.

2. Sorting process:

The material is evenly spread on a flat plate (conveyor belt) through a vibrating feeding device and enters the magnetic zone. Magnetic particles are adsorbed onto the surface of a flat plate under the action of a magnetic field, and detach when the plate moves to the non-magnetic zone (such as the edge of the magnetic field or the discharge end). Non magnetic materials are not affected by magnetic forces and fall along natural trajectories to achieve separation.

3. Sorting method:

Wet sorting: used for slurry, where magnetic particles adsorb and wash away non-magnetic parts with water flow.

advantage

1. Efficient sorting: The magnetic field strength can be adjusted or designed specifically to meet the sorting needs of different magnetic materials, with a high recovery rate.

2. Energy saving and environmental protection: Permanent magnet type does not require electrical energy and is pollution-free;

3. Simple structure: no complex moving parts, low maintenance cost, low failure rate, and long lifespan.

4. Flexible application: It can handle particles or slurries and is widely used for ore selection and waste iron removal.

5. Automation integration: easy to integrate with production lines, achieve continuous operation, and improve production efficiency.

3、 Typical application scenarios

Mining: Separation or tailings recovery of magnetite and limonite.

Ceramics/Glass: Removing iron impurities from raw materials to improve product whiteness.

Renewable resources: metal recycling from electronic waste and scrap steel.

Food and pharmaceuticals: Removing trace iron filings from raw materials (requiring hygiene grade design).
