Glass Sorting

For the sorting of recycled glass ware, e.g. hollow glass 5 - 60 mm flat glass 8 - 40 mm fine flat glass 0,5 - 8 mm Mogensen can offer various machine types: MikroSort® AX The MikroSort® AX is specially designed for the sorting of big quantities of rejected material and strongly impurified recycled hollow glass ware within a particle range of 5 to 60 mm. Recycling glass makes different demands on the automatic sorting system. The material is hardly ever washed, is often wet due to outdoor storage and contains, in addition to the actual undesired colours and CSP (ceramic material/stones/porcelain), a lot of other fine material, paper and organic residues. For the end product, however, even the finest differences must be detected, i.e. it must be possible to tell white from light green, ceramic fragments from white glass with paper labels and chocolate residues from brown glass. In order to meet these requirements, the material is detected in free fall and by means of a special illumination. Contamination by fine material and paper is minimised by appropriate measures and all relevant areas are equipped with automatic cleaning systems. Such, the sorting stays very stable on a high level, even under unfavourable conditions. MikroSort® AL The MikroSort® AL is specially designed for the recycling of flat glass (window panes and car panes) within the particle range of 8 to 30 mm. The input material is either washed and dried or damp, distinguished by very fine colour shades and is contaminated by rubber, foil and metal residuals. For this task, the material is detected directly on the chute with the illumination behind. MikroSort® AF The MikroSort® AF is designed for special applications with flat glass in the particle size range of 0.5 - 4 mm. The material has been dried and screened into very small particles. This material is mostly contaminated by light and dark off-colours and rubber and foil residues. The input material is scanned as with the type AL, however, because of the reduced working width, one can work with a distinctly higher resolution. The MikroSort® AF scans bulk goods on a working width of 900 mm in free fall by means of a colour line camera. The respective data is evaluated by a freely programmable sorting software of an industrial computer by colour, brightness and size into good product and rejected parts. The computer passes this information to 224 fast and robust compressed air valves, each of which serves one compressed air nozzle. Rejected parts are evaluated by position, shape and size and blown out of the material stream by specific jets of compressed air. Depending on the material, particle size distribution and the quantity of rejected material quantities between 8 to 20 t/h with the AX/AL and 2 to 5 t/h with the AF may be sorted. Advantages of MikroSort®: Inexpensive sorting of strongly contaminated, broken recycling glass by colour and brightness is possible (AX). Slightest colour differences (e.g. white and half white, window pane and vitrophyre glass) are reliably detected and are available as sorting parameters (AL). Rejection rates of up to 50% (white glass from mixed glass or processing of CSP (ceramic material/stones/porcelain) may be realised in continuous operation. The material yield is maximised by accurate detection and exact sorting. Fine metal parts are detected parallel to the colour sorting and fed into the rejection stream. Thanks to the exact detection, the small distance of the nozzles to the product stream and the fast, precise triggering of the valves, the compressed air consumption is kept very low. Low-maintenance operation thanks to automatic cleaning. Also refer to our technical paper: Glass Recycling. Click here to open information leaflet Mogensen MikroSort® AX.

Sizer

The Mogensen Sizers® system is made up of several screening decks which are arranged on top of one another and have different inclinations. The meshes are bigger in the upper decks and smaller in the lower decks. The maintenance-friendly screen linings are excited in a compact case by motor vibrators or directional exciters. While the finer particles of the material fall through the larger meshes of the upper deck almost vertically, the larger particles are filtered out of the material flow. Due to the different inclination of the screen linings, their openings have the effect of a smaller mesh. For this reason, the mesh widths can be unusually large compared to conventional flat-design screens at the same separation efficiency. The separation of different particle sizes from the material flow and the larger mesh width not only prevent the deposition of material layers and clogging of material on the screen linings, but also ensure, in addition to the high throughput, an extremely long service life of the screen linings.

Vibrating Conveyors

Mogensen Vibrating Conveyors distinguish themselves by their robust and vibration-resistant design. Mogensen Vibrating Conveyors can be used both as conveyors and as discharge conduits under bunker load. They are driven by 2 unbalance motors working in opposite directions at a constant speed. Upon request, a frequency converter type JF can be supplied for continuous speed adjustment. The conveyor trough can be provided, as a standard, with three different wear-resistant linings, e.g. manganese steel lining, rubber lining or ceramic lining. As from type series BS, the whole trough can be replaced. Mogensen offers a graduated conveyor program as basic design versions, customized solutions are also available upon request.

X-ray sorting

Mogensen developed, in co-operation with CommoDaS, Wedel, a sorting machine which separates various bulk goods by means of x-ray sensors. 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.
