X-ray sorting machine
Mogensen
This new technology was initialised because of the new waste deposit decree by which the depositing of raw household and industrial waste is regulated as from June 1st, 2005. As from this date, this waste has to be separated into pure inorganic and organic fractions. The organic fraction may be used as high quality fuel substitute and should contain as little ash as possible. The inorganic fraction should be an inert product and should have an ignition loss of less than 5%. Exceeding this limit continuously results in higher deposit costs.
The differentiation in this area reaches its limits with the usual sorting by sight but also with the colour sorting. The x-ray technique, however, distinguishes material with similar colours and weights by a further criterion, i.e. the density or, more specific, by the absorption of x-rays. Organic parts like wood and plastic are unmistakably distinguished from inorganic parts like stones, glass or ceramics.
Data received from the x-ray sensor are evaluated by a high-performance computer in real time and the sorting decision is forwarded to extremely fast compressed-air valves. The valves are triggered according to the size and position of the parts to be rejected and accurately deflected.
