Master Magnets will show how to protect crushers, screens and conveyors from tramp metal damage
On stand C9 at Hillhead 2018, Redditch-based Master Magnets will be demonstrating how the combination of magnetic separators and metal detectors is the best way to protect crushers, screens and conveyors from damage caused by metal.
Master Magnets are one of the world’s leading designers and manufacturers of magnetic separators and metal detectors for the recycling, quarrying and mining industries. In January 2017, Master Magnets became part of the Bunting Magnetics group of companies.
Removing the ferrous or magnetic metal is the first step taken to protect processing plant. This is commonly achieved using either a permanent overband magnet or electro overband magnet.
The permanent overband magnet is one of the most commonly used magnetic separators on mobile crushers and suspended over conveyers in quarries and mines, and in recycling plants. At Hillhead, Master Magnets will be displaying examples of both self-clean and manual-clean permanent overband magnets.
Metal detectors are often positioned after magnetic separators to protect processing plant against damage from non-ferrous metals such as digger teeth, drill rods, crusher plates, bars, chains, nuts and bolts, other manganese steel parts etc, all of which can be extremely hazardous to crushers, shredders and other types of processing machinery.
Master Magnets’ TN77 and QTA metal detectors will be on display at the show. The electronic TN77 is a tunnel-type unit that is installed on conveyor systems. It is one of the most commonly installed metal detectors in quarries and mines, allowing continuous inspection of any non-metallic or non-conductive material and identifying tramp iron and manganese steel.
The QTA metal detector is capable of detecting all tramp metals, whether ferrous, non-ferrous or manganese steel. For easy installation on belt conveyors, the QTA search coil can be dismantled at one end, eliminating the need to cut and re-vulcanize conveyor belts.
The Master Magnets team will also be talking to visitors about the Mastertrax mobile eddy current separator. The Mastertrax incorporates a 1,500mm wide high-intensity concentric eddy-current separator along with a rare-earth drum magnet, providing separation of ferrous and non-ferrous particles down to 5mm.
Optimum operating settings will allow users to process up to 25 tonnes/h, depending on material density. The machine, which comes with crawler tracks, an on-board diesel generator and hydraulic power pack, offers easy site manoeuvrability and can be transported on a low-loader trailer without permits.
Information on other metal separation equipment, including eddy-current separators, drum magnets and pulley magnets will be available on the stand.
