Suspended Permanent Magnetic Separators

Working Principle

Suspended Permanent Magnetic Separators operate by projecting a deep, dense permanent magnetic field directly through the moving product bed below. The entire unit is securely suspended above the conveyor line using reinforced lifting holes and adjustable tension rigging. As raw materials containing sharp iron pieces, bolts, or wire scraps pass smoothly beneath the permanent magnetic matrix, the ferromagnetic contaminants are instantly pulled upward against gravity and accumulate tightly on the lower face of the housing. The isolated impurities are then manually scraped off during routine maintenance intervals, allowing the system to maintain its high separation efficiency across continuous plant production processes without affecting the main material flow.
 

Structure and Heavy-Duty Material Engineering

The internal permanent magnetic structure of each Suspended Permanent Magnetic Separator manufactured by MagnetGlobal features a proprietary combination of high-coercivity ferrite magnets and high-energy rare-earth Neodymium (NdFeB) blocks. This advanced hybrid configuration is mathematically optimized within a heavy-duty magnetic circuit to project a massively extended magnetic flux throw capable of pulling iron through exceptionally deep material burden depths. The exterior containment casing is fabricated from thick, structural-grade A3 carbon steel, with options to specify SUS304 or SUS316L stainless steel wrappers for highly corrosive chemical plants or sanitary food-grade processing lines. To ensure maximum mechanical reliability in rugged quarry or mining environments, the heavy-duty lifting handles are crafted from thick Q235 carbon steel and joined via a multi-pass fish-scale welding process, providing exceptional mechanical strength and certified structural load-bearing capacity.

Technical Parameters

Note: Customization is available based on conveyor belt width. Length, width, and height can all be customized according to actual usage requirements.

Installation Methods

1. Suspended installation above conveyor belt

This is the most common installation method. The separator is suspended above the conveyor belt using crossbeams, adjustable bolts, and lifting eyes.
The suspension height is adjusted within the effective operating range (typically 100–300 mm), ensuring the separator remains parallel to the belt and does not come into contact with the conveyed material.

2. Suspended installation above hopper or chute

For systems without conveyor belts, the separator can be installed above the hopper outlet or chute using a support frame. As materials pass through the magnetic field, ferrous impurities are effectively separated.

3. Frame-mounted installation

For heavy-duty separators or locations without existing support beams, a steel support frame can be installed. The separator is fixed onto the frame and adjusted to the optimal height. This method provides high stability and is suitable for high-speed, high-capacity conveying systems.

Applications

Implementing a Suspended Permanent Magnetic Separator into your production facility can be accomplished through multiple flexible mounting orientations without expensive structure modification. The most common approach is a suspended horizontal installation directly above the conveyor belt using crossbeams, adjustable turnbuckles, and heavy-duty lifting eyes, maintaining a parallel alignment typically 100 to 300 millimeters above the belt surface so it never contacts the raw material. For plants lacking conveyor systems, the plate can be suspended above a gravity hopper outlet or vertical chute via a custom-tailored external support framework to trap metal as bulk items cascade downward. Additionally, for high-capacity, high-vibration sorting systems, a dedicated steel rigid frame-mounted installation can be provided to anchor the heavy plate securely over conveyor discharge head pulleys.
 

Suspended magnetic separators are widely used in mining and aggregate processing, construction waste recycling, grain and animal feed handling, chemical and plastics industries, as well as waste treatment and recycling operations, providing reliable iron removal for conveyor-based production lines.
