Mounted & Suspended Separation Magnets
MPI’s Mounted and Suspended Sorting Systems are designed to safeguard processing equipment, enhance product purity, and optimize operational efficiency by eliminating unwanted tramp metal from conveyed product streams. Suitable for both high-speed conveyors and deep burden depths, MPI offers electromagnet and permanent magnet options, available in Quick-Clean or Self-Clean configurations to meet your specific maintenance and throughput requirements. These systems are ideal for various industries, including recycling, aggregates, food processing, and mining, where metal contamination can pose substantial safety and quality concerns. With models tailored for both dry and wet applications, MPI’s magnetic separators ensure robust performance, reduced downtime, and adaptable installation options.
Mounted and Suspended Sorting Systems also shield downstream equipment from damage, diminish the risk of fire and explosion associated with spark-generating tramp metal, improve product quality by removing contaminants, and boost system efficiency with minimal manual intervention. They are available in both manual and automated cleaning options, allowing for customized maintenance control. Supported by MPI’s expertise in magnetic separation, these systems deliver dependable, low-maintenance solutions tailored for challenging industrial environments.
Quick-Clean Suspended Receiving Belt Magnet
Offering high-intensity magnetic separation without electrical power, this permanent magnet is ideal for applications with belt speeds up to 250 FPM. Its large magnetic face allows significant tramp metal accumulation before cleaning, and its quick-clean feature minimizes maintenance time in low-to-moderate volume applications.
Self-Clean Suspended Receiving Belt Magnet/Cross Belt Separator
Designed for continuous operation on fast conveyor belts, this self-cleaning system provides consistent tramp metal removal without requiring power. Its space-saving profile fits tight installations, while the automatic discharge belt ensures uninterrupted processing of large or small material volumes, wet or dry.
Quick-Clean Suspended Electromagnet
Engineered for demanding material handling environments, this oil-cooled electromagnet effectively captures both large and small tramp metal from conveyed products with heavy burden depths. The quick-clean design simplifies maintenance while ensuring consistent performance, making it ideal for moderate-speed belt or vibratory conveyors up to 250 FPM.
Self-Clean Suspended Electromagnet
This robust system combines oil-cooled electromagnet power with an integrated self-cleaning belt to automatically discharge captured tramp metal. It’s built to handle fast-moving conveyor belts and high product volumes, reducing manual intervention while maximizing operational uptime.

Regulations and Requirements
Food Processing
Regulations & Standards:
FDA (U.S. Food and Drug Administration) – Regulates food contact equipment; magnetic separators must comply with hygienic design principles.
FSMA (Food Safety Modernization Act) – Mandates preventive controls and foreign material contamination prevention.
GFSI (Global Food Safety Initiative) – Includes schemes like SQF, BRC, and FSSC 22000; requires foreign object prevention plans.
HACCP (Hazard Analysis and Critical Control Points) – Magnetic separation is a common CCP (Critical Control Point).
USDA / 3-A Sanitary Standards – For dairy and meat plants; magnets must meet sanitary design standards in specific facilities.
Quality Requirements:
Regular magnet strength testing (often using pull-test kits)
Documentation of cleaning/inspection schedules
Material traceability and non-ferrous metal detection
Recycling & Scrap
Regulations & Standards:
EPA (Environmental Protection Agency) – Oversees waste management and recycling compliance (especially MSW and e-waste).
ISRI (Institute of Scrap Recycling Industries) – Guidelines for ferrous/non-ferrous sorting quality.
Local/state environmental regulations – For facility emissions, sorting accuracy, and landfill diversion goals.
Quality Requirements:
Separation efficiency standards (e.g., % ferrous recovery)
Conveyor belt and equipment protection specs
Compliance with safety and spark/fire prevention measures
Mining & Aggregate
Regulations & Standards:
MSHA (Mine Safety and Health Administration) – Mandates machinery safety, including guarding and tramp metal removal.
NIOSH Guidelines – Recommendations for dust explosion prevention.
ISO 9001 or 14001 (optional but common) – Quality and environmental management systems.
Quality Requirements:
Reliable magnet performance at high burden depths
Fire prevention (tramp metal = potential ignition source)
Machine uptime and maintenance tracking
Plastics, Rubber, Wood, Cement, and Others
Regulations & Standards:
NFPA (National Fire Protection Association) – Applies especially to dust-producing processes (wood, plastic, grain).
OSHA (Occupational Safety and Health Administration) – Equipment guarding, operator safety, and arc flash standards.
ANSI & ISO Standards – For equipment design, ergonomics, and operational safety.
Quality Requirements:
Tramp metal removal to prevent equipment wear and downtime
Maintenance logs for magnet performance and cleaning
Integration with automated QC systems (e.g., sensors, rejection gates)
Additional Considerations
Customer-specific QA specs: Many OEMs and processors set their own stricter metal detection/removal tolerances.
Recordkeeping: Documentation of cleaning cycles, inspection logs, and magnet pull test results is often required during audits.
Fire prevention systems: Especially in facilities handling flammable dusts or explosive environments.
