Magnetic Separation Solutions for the Aggregate, Minerals, and Mining Industries
MPI’s magnetic separation systems protect equipment, improve product quality, and ensure process efficiency in aggregate, mineral, and mining operations. These environments often process abrasive, high-volume, and metal-laden materials such as sand, gravel, limestone, crushed rock, ores, and recycled concrete. Unwanted tramp iron and ferrous contaminants, introduced through raw material handling, equipment wear, or scrap metal intrusion, can severely damage crushers, screens, conveyors, and mills.
MPI magnets remove these hazards upstream before they cause damage and downstream to ensure final product purity. The goal is to:
Prevent costly downtime
Extend equipment life
Protect belts and crushers
Meet customer quality specs
Reduce maintenance and risk
Magnetic separators are used throughout the material flow, from receiving and primary crushing to screening, stockpiling, and loading out. Typical placement includes:
At infeed conveyors to remove rebar, bolts, or scrap from raw material
Ahead of crushers, screens, or grinders to protect wear surfaces
After primary or secondary crushing to remove liberated metal fragments
Before final stockpile or bagging, to ensure a contaminant-free product
At recycling recovery points for concrete, asphalt, or mineral fines
MPI’s solutions provide critical protection and process assurance across the entire mining and aggregate value chain. From reducing downtime and protecting expensive equipment to ensuring high-purity product output, MPI products are purpose-built for tough applications and customizable to your facility’s needs. These systems increase ROI, reduce risk, and support consistent, high-volume production under extreme operating conditions.

Features and Benefits for Aggregate, Minerals, and Mining from Magnetic Products, Inc
Heavy-Duty, High-Impact Construction
MPI separators are built with rugged housings, abrasion-resistant liners, and heavy-duty frames to withstand harsh quarry and mining environments with minimal wear.
Reliable Tramp Metal Removal
Powerful permanent and electromagnets remove dangerous ferrous materials from the flow, protecting crushers, screens, and conveyor belts from catastrophic damage.
Continuous Operation with Minimal Downtime
Self-cleaning and manual-cleaning options allow operators to remove metal without halting material flow, which is essential for 24/7 production in mining and aggregate plants.
High-Throughput Efficiency
MPI’s magnetic solutions are designed to handle large material volumes without choking or flow restriction, maintaining peak plant productivity.
Field-Configurable Mounting Options
Chute, crossbelt, inline, and overbelt installations allow flexible magnet placement across mobile and fixed plant layouts.
Reduced Maintenance Costs
MPI products reduce unplanned maintenance, downtime, and part replacement costs by preventing metal-induced equipment damage.
Enhanced Product Quality and Purity
Magnetic separation ensures the final material is free from iron fragments, increasing product value and meeting downstream customer and end-user specifications.
Scalable and Customizable Solutions
MPI offers standard and engineered solutions to fit a wide range of belt widths, flow rates, and installation constraints.
