Two Pneumatic In Line Magnets Capture Tramp Metal
A UK processor of Potassium Chloride is using two Pneumatic In Line Magnets (PIMS) to capture and remove small tramp ferrous metal. The metal is removed early in the process, as the dry material is being pneumatically conveyed, to prevent damage to processing equipment including the crusher. The two PIMS installed at the Potassium Chloride processing plant are both located outdoors.
Potassium Chloride (KCl) is a metal halide salt composed of potassium and chlorine. The salt has a number of applications including in medicines to treat low blood potassium and in food processing as a substitute for salt, although the main use is as a fertilizer in the form of potash.

- Plastics Producer Purchases 6 In Line Magnetic Separators;
Pneumatic In Line Magnets Specification
The two PIMS are identical in specification:
- 150mm (6″) inlet and outlet;
- High intensity Neodymium Rare Earth Magnets with tapered steps;
- 316 Stainless Steel food-grade housing and contact parts to prevent salt-induced corrosion;
- Suitable for pressurised pipelines up to 15 psi;
- Mounted horizontally;
- Simple swing-arm mechanism for each cleaning of captured ferrous metal from the magnet face;
- Overall length: 1320mm;
Advantages of the In Line Magnet
The In Line Magnet is a popular magnetic separator as it allows material to flow without restriction. In operation, either pneumatically transported or gravity-fed material passes over the face of a strong Neodymium Rare Earth Magnet. The magnet face has a tapered step, which enhances the magnetic field, whilst also keeping captured ferrous metal out of the material flow. Periodically, on a frequency dependent on the level of metal contamination, the captured ferrous metal is manually removed from the magnet face.
The In Line Magnet is one of many designs of magnetic separator used in the food processing and bulk handling industry. For further information, please contact us via:
