A magnetic separator is essential when processing reinforced concrete: it extracts ≥98% of steel, meets the standards for recycled aggregate, and reduces equipment wear by 40–60%. An overhead conveyor-mounted model with neodymium magnets is suitable; conveyor speeds exceeding 1.8 m/s reduce efficiency.
When processing reinforced concrete, a magnetic separator is essential equipment; according to the Engineering Reference Scope, for standard production lines, the proportion of steel inclusions in the raw reinforced concrete mix ranges from 7 to 12 per cent.
According to actual test data from industrial reinforced concrete processing lines, the magnetic separator achieves a recovery rate of at least 98 per cent for rebar offcuts and other ferromagnetic components, with a throughput capacity of up to 50 tonnes per hour
According to the official standards for recycled crushed stone obtained from the processing of reinforced concrete, the proportion of unrecovered steel particles larger than 5 millimetres must not exceed 0.1 per cent; this figure can only be achieved by using a functional magnetic separator.
According to calculations by crushing plant manufacturers, the presence of unremoved steel inclusions in the feed material increases wear on the crushing plates and hammers by 40 to 60 per cent over a 1,000-hour operating cycle
Magnetic system type: permanent neodymium magnets; magnetic field strength on the separator surface: 120 to 450 mT; installation type: mounted above a belt conveyor; mounting height above the conveyor: 150 to 400 millimetres; permissible line throughput from 10 to 200 tonnes per hour
Is it possible to do without a magnetic separator when processing reinforced concrete on a small scale? Even when processing fractions down to 20 millimetres, steel inclusions measuring between 2 and 10 millimetres remain in the material in quantities of up to 8 per cent, which renders the end product unsuitablefor most construction purposes. What type of magnetic separator is suitable for standard reinforced concrete recycling lines? The most common option is an overhead conveyor separator with permanent neodymium magnets; it ensures the required extraction rate under standard line parameters. DoesDoes the conveyor speed affect the efficiency of the magnetic separator? According to measured data, when the conveyor belt speed exceeds 1.8 metres per second, the recovery efficiency of large steel inclusions decreases by 7 to 12 per cent
