Cleaning of material is effected via separation into four fractions.
The material wich is stored in a metering silo will be continuously fed on to the whole infeed width of the Chip Cleaning Plant. Within the Chip Cleaning Plant separation of mineral impurities (fraction 1) is effected via the transport of the recycling chips over a screen with vibrating drive.
Pulsating air is blown through the entire screen surface from below. The specific light materials such as dust, paper and foil pieces etc. will be stirred up by the air flow and will thus be sucked off. A cyclone separates the impurities from the material flow (fraction 2).
The coarse foreign bodies (fraction 3) will be transported on the vibrating screen
due to their own weight. After floating against V-shaped guiding plates, they are lead into secondary sifting units wich are mounted on the left and right side of the machine.
Within the secondary sifting units the coarse impurities are further separated from the remaining wood chips by up-current classification. The wood fraction will be reintroduced to the cleaning process via return screw conveyors.
Due to the blow-effect on the screen the cleaned accepts float (fraction 4) on an air cushion and will thus be lifted over the guidance plates before they are then discharged via screw conveyor and/or belt conveyor.
The installation of a Maier Chip Cleaning Plant type MHR in a new or an already existing plant will entirely meet the steadily increasing demand (of e.g. the particleboard industry)
for value added high quality chips.
The thus value added final product will offer further marketing possibilities and sales opportunities to the operator.
