Grate and Tube Magnets

MPI Grate Magnets and Magnetic Tubes are widely used across various industries that require contamination control and equipment protection. Key industries include:

• Food Processing – Prevents ferrous contamination in bulk powders, spices, grains, dairy products, and other food ingredients.

• Plastics & Rubber – Ensures the purity of plastic resins, pellets, and regrind materials to improve final product quality and prevent machinery wear.

• Pharmaceuticals – Maintains strict contamination control in powdered medications, tablets, and other pharmaceutical production processes.

• Chemicals & Petrochemicals – Removes ferrous contaminants from fine chemical powders, granules, and liquids used in industrial processing.

• Mining & Aggregate – Extracts metal particles from crushed rock, sand, and other mining materials before further processing.

• Recycling & Waste Processing – Helps recover valuable metal from shredded materials, e-waste, and other recyclable goods.

• Powder & Bulk Solids Handling – Used in any process involving dry powders, granules, or bulk materials in conveying or storage applications.

• Ceramics & Glass Manufacturing – Ensures the quality of fine ceramic powders and glass materials by removing metal contaminants.

Grate Magnets and Magnetic Tubes are designed for a wide range of applications, including:

• Gravity-Fed Material Flow Systems – Installed in hoppers, chutes, and ducts where materials flow naturally by gravity.

• Bulk Material Handling – Placed in bins, silos, or feeders to capture tramp metal before processing.

• Injection Molding & Extrusion – Used in plastic and rubber industries to prevent metal contamination in raw materials.

• Powder Processing & Blending – Integrated into mixing and milling equipment to maintain product purity.

• Pneumatic & Liquid Processing Lines – Magnetic tubes can be housed in custom enclosures for use in liquid and semi-liquid material processing.

• Metal Detection & Separation – Used as a preliminary step before more advanced separation equipment like eddy current separators.

• Packaging & Final Product Inspection – Ensures ferrous metal contamination is removed before products reach consumers.

MPI Grate Magnets and Magnetic Tubes help industries comply with stringent regulations, codes, and quality standards by ensuring product purity and preventing contamination. Key compliance areas include:
