Tube & Grid Magnets

Description

Tube Magnets, also known as magnetic rods, grid magnets, or cartridge magnets, are engineered to achieve the optimum balance between magnetic throw and holding force, they are designed for mounting individually or in multi-row grid arrays; providing a versatile product for both dry and wet gravity-free-fall magnetic separation applications.

The range includes standard-strength Ceramic Ferrite and high-strength Rare Earth Neodymium.

Tube Magnets are available in both standard and heavy-duty models and are constructed of durable 304 stainless steel tubing, with 316 available for specific applications. The ends are fully welded with the option of threaded holes, threaded rods, or plain water-tight sealed end plugs. The standard diameter of a Tube Magnet is 25.4mm (1”) with standard lengths from 100mm to 600mm.

Tube Magnets are commonly constructed into a Grid for installation in hoppers, pits, chutes, housings, and bins. Grid Magnets, otherwise known as Grate Magnets, are available in a wide range of dimensions, both circular or square, to meet application requirements. Additionally, Grid magnets are available in food and sanitary grades to meet specific industry standards.

Tube and Grid Magnets feature in Drawer Filter Magnets, where they are mounted within a sealed housing for easy installation into a process line.

Operation of Tube and Grid Magnets

In operation, a liquid or dry product is passed over the surface of the Tube Magnet, where magnetically susceptible particles are attracted and held by the magnetic field. Periodically, in accordance with the degree of ferrous metal contamination, the Tube or Grid Magnets are manually removed for cleaning.

Tube Magnets and Grid Magnets Models

The range of Tube and Grid magnets includes:

• Standard-strength Ceramic Ferrite – ideal for separating large tramp ferrous metal such as nuts, bolts, screws, etc;
• High-strength Rare Earth Neodymium – intense magnetic power for capturing fine iron and abraded stainless steel in applications with special magnet specifications for applications where the temperature exceeds 80°C:
  • 11,200 Gauss;
  • 10,000 Gauss;
  • 4,000-5,000 Gauss;
  • 2,500-2,900 Gauss;
• High-strength Rare Earth Samarium Cobalt for very high-temperature applications above 180°C;
