Design and operation
Feeding auger evenly distributes grain heap on the width of the machine and feeds it on a sieve conveyor that separates large impurities. With the purpose of intensification of the process, the driven branch of conveyor is shaken by the activators. Material, which has passed through the sieves of conveyor is divided into two streams and fed by the feeders into pneumatically separating channel. The air flow generated by the fan, selects the lightweight impurities which are entrained into the sedimentary chamber and then with the screw conveyor are removed outside of the machine. Cleaning of the exhaust air from the aspirated impurities is performed in a cyclone
Specific features of design
► effective air cleaning system with two zones of material input into pneumatically separating channel, arranged with horizontal and vertical offsets relatively each other, provide high performance of the separator;
► the work of the activators in "gentle" mode increases service life of the screen conveyor;
► replacement of the screen conveyor runs through the front hatch of the cleaner without dismantling the drive mechanisms, which significantly reduces the complexity of this operation;
► a number of technological hatches and inspection windows provide easy maintenance and adjustment of machines;
► independent aspiration system of open type with filtering of exhaust air in cyclones considerably reduces the dustiness of the working area, providing a comfortable working environment for the operator.
