Removing Tramp Metal from Mining, Cement & Aggregate Processing
Tramp metal in mining, cement and aggregate processing is removed with a magnetic pulley at the conveyor head/discharge point, or a magnetic drum separator and cross belt separator for continuous, high-volume bulk material flow. Large tramp metal — bolts, rebar, wire, worn equipment parts — reaching a crusher or mill causes serious damage and unplanned downtime. Below is which equipment fits which point in your process.
Why It Matters
- Crusher and mill damage — a single piece of large tramp metal reaching a crusher or grinding mill can cause catastrophic, expensive damage.
- Conveyor belt damage — sharp tramp metal can puncture or tear conveyor belting, an expensive and disruptive repair.
- Unplanned downtime — equipment failure from tramp metal means unscheduled stops on high-volume, continuous operations.
Which Equipment Fits Your Line
Magnetic Pulley — replaces or supplements a standard conveyor head pulley, continuously pulling tramp iron out at the discharge point without a separate unit to install. The standard solution for mining, ore dressing, cement and coal handling plants.
Magnetic Drum Separator and Magnetic Cross Belt Separator — for higher-volume or higher-contamination lines needing a dedicated, self-cleaning unit rather than an integrated head pulley.
Frequently Asked Questions
Why is tramp metal dangerous in a crusher or mill?
Large tramp metal — bolts, rebar, worn equipment parts — can cause catastrophic mechanical damage to crushing and grinding equipment, resulting in expensive repairs and unplanned downtime.
Where should a magnetic pulley be installed on a conveyor?
At the head or discharge point of the conveyor, where it replaces or works alongside the standard head pulley to continuously remove tramp iron as material discharges.
Can this handle large rebar or scrap metal, not just fines?
Yes — magnetic pulleys and drum separators are designed to capture both large tramp metal and finer ferrous contamination in the same pass.
Is this suitable for cement plants specifically?
Yes — cement and coal handling plants are a standard application for PML's Magnetic Pulley range, alongside mining and ore dressing operations.
