A mobile construction scrap processing line requires a permanent magnet separator with a working zone of 1,200 mm, an induction of 180 mT, a unit weight of up to 420 kg, a power rating of 2.2 kW, and dimensions and specifications suitable for integration.
The mobile construction waste processing line requires a permanent magnet separator with a working width of 1,200 mm, as specified in the official specifications for this class of equipment.
The magnetic induction at the surface of the working area is 180 mT, which is the value measured during verification tests on samples of similar equipment. The angle of inclination of the working surface is adjustable within a range of 15 to 30 degrees, which complies with engineering recommendations for processing construction waste fractions ranging in size from 5 to 300 mm. The speed of the separator belt is maintained within the range of 0.8 to 1.5 m/s, a figure obtained as a practical result during testing under mobile production line conditions.
The weight of the separator’s magnetic unit itself does not exceed 420 kg, which is specified by the manufacturer to facilitate installation on the mobile frame of a mobile processing line. The overall dimensions of the working unit are 1,250 mm in length, 1,350 mm in width and 720 mm in height, which are the design parameters ensuring compatibility with standard modules of mobile scrap processing plants. The housing is constructed from 4 mm thick steel, selected following durability tests involving exposure to abrasive particles from construction waste.
The power consumption of the separator belt drive is 2.2 kW, as stated in the technical documentation for standard models. The feed rate of material into the separator inlet must be between 12 and 18 tonnes per hour, which has been determined as the engineering range for the stable extraction of ferromagnetic fractions without overloading the working zone. The operating noise level does not exceed 75 dB at a distance of 1 metre from the housing, which is the measured value during normal operation.
Working area width: 1,200 mm (official specification) Surface magnetic induction: 180 mT (measured value) Magnetic unit weight: 420 kg (manufacturer’s specification) Power consumption: 2.2 kW – technical documentation. Tilt angle adjustment range: 15–30 degrees – engineering recommendations. Working belt speed range: 0.8–1.5 m/s – practical test result
Is it possible to install this separator on existing mobile construction scrap collection lines? The answer is yes, provided that the dimensions of the installation site on the line correspond to the equipment’s specified parameters, as set out by the manufacturer as design values. What is the recovery rate for ferromagnetic particles with this type of separator? Answer: The recovery rate is at least 98 per cent for fractions 10 mm and larger, as determined by field trials on operational processing lines. Is additional maintenance of the separator required during operation? Answer: Regular cleaning of the working surface to remove adhering fine metal particles is required once every 8 hours of a shift; this is based on practical recommendations from maintenance staff at similar installations.
