The recently begun project teamwork work between Goudsmit Magnetic Systems in Waalre and AVG Milieutechniek in Heijen ensures that levelled ground in the district council of Eindhoven is made munition-free. Residential homes are to be built on this ground. For the preparation of large areas of ground, AVG, which specialises in the field of explosives detection, has fitted out a special site. The removal of the munition happens by means of various separation techniques, such as the sifting of different sections of ground by sieving equipment. A magnet, non-ferrous separator metal detector removes metals, including the munition.
Process
First of all a sieve takes the 0 – 20 mm sections from the soil; this soil is immediately new, fine soil. The present munition is larger than 20 mm. The remainder flow is excess (everything from 20 mm to around 130 mm) and goes under two overbelt magnets for the separation of the iron (munition) parts. The remainder then falls into a triller-pipe which is fed by the 1500 mm wide Eddy Current separator. This Eddy Current separator removes all non-ferrous (munition) metal parts such as aluminium, copper and brass. As a final check the soil flow goes through a metal detector.
