MAROT - Model A - Suction Grain Cleaners
The Suction cleaners are used to remove the grain and the light waste it contains whilst retaining the heaviest products for subsequent retrieval. They are used alone or in association with a grid pre-cleaner or a trash catcher. The grain, introduced into the device by feed hopper G, emerges as a uniform sheet by means of an adjustable shutter. A current of air blows through the sheet removing lightweight products. A distributor adjusted by a thumb-wheel ensures straw products are regularly removed. The heaviest products fall into a holding chamber and are removed by screw M while the others are ejected. These pre-cleaners are compact and integrate very easily into reception systems without limiting their flow rate: 70 to 500 tonnes per hour.
