Tramp Metal Detector
designed for magnetite iron ore
Fe3O4 even with iron content up to 70%, without loss of performance
The BARRIER tramp metal detector was installed to replace the existing unit, which could not handle the lithium ore stream. The BARRIER operates stably with zero ore effect and provides reliable tramp metal detection.
The BARRIER tramp metal detector is installed on the polymetallic sulphide ore conveying line, with a metal content of up to 15%, on a 1000 mm wide conveyor belt.
The extreme conditions of Kazakhstan, with temperatures ranging from –50 °C in winter to +50 °C in summer, are no challenge for the Tramp BARRIER metal detector. It delivers flawless performance on iron ore with an iron content of 32%. Steel structures are positioned so close they almost touch the metal detector — with the BARRIER, this is possible.
Expanded clay raw material with 16% iron oxide (Fe₂O₃) is invisible to the BARRIER metal detector. It reliably detects even the smallest pieces of tramp metal that could damage production equipment.
Magnetite iron ore (36.3% Fe; 21.7% magnetic Fe) is exactly what the BARRIER was originally designed for. It operates flawlessly on magnetite without any loss of sensitivity, delivering outstanding performance while reliably detecting non-magnetic manganese steel.
Direct installation of the metal detector right next to the magnet — a feature no other detector in the world can match, except the BARRIER. Underground iron ore mining (martite/hematite), Fe ~58–62% (up to 64% in top-grade).
A light task for the BARRIER Tramp metal detector — magnesite with only 8% iron content. Even the presence of a metallic joint has no impact on its sensitivity, as the BARRIER can detect tramp metal right at the joint
The BARRIER metal detector is installed directly above the cone crusher. Despite extreme vibration, the system fully compensates for it — zero false trips. Aggregate plant.
Heavy mineral sands conveyed on a steel cord belt are reliably monitored by the BARRIER metal detector, ensuring stable detection with a guaranteed absence of false trips.
The BARRIER metal detector is installed at an iron ore mining operation in Australia, handling ore with 60% iron content. This ore has absolutely no impact on the BARRIER, which operates immediately on default settings.
Iron ore fines with 62% Fe content are delivered by vessels and transported to the sinter plant. The amount of metal in the ore is impressive — yet the Tramp metal detector BARRIER provides guaranteed protection.
The Mining Metal Detector Barrier-409 is installed on a conveyor with a 700mm-wide belt to detect foreign metals, including manganese steel, in the transportation of magnesium carbonate (MgCO3) with an additional iron content of up to 6%.
The Metal Detector Barrier is installed on a conveyor transporting gold ore and operates in ambient temperatures up to 45°C in summer and down to minus 45°C in winter.
The BARRIER metal detector is installed at a cement plant on the slag conveying line, operating on a steel-corded belt 1400 mm wide.
Brick plant. Simple material flow, maximum reliability of the BARRIER metal detector, and outstanding sensitivity.
Magnetite iron ore is supplied from several open-pit and underground mines; the feed composition varies: Magnetite 14–48%, Hematite 1.5–12%. The Tramp metal detector BARRIER maintains excellent performance across these variations with no need for re-tuning.
