TNL TECNAL´s pre-cleaning and cleaning system has a uniform feeding, with chambers and flow doser. The expansion chambers are independent, one for each suction column, with efficient removal of hulls and light impurities. The residues and impurities retained on the screens are removed by a self-cleaning system with rubber balls.
The suction chambers can be adjusted regardless the air flow of each one, which allows dragging the maximum of the impurities without dragging the grains. The centrifugal fan for the suction columns has a cyclone for separation of impurities for bagging. The discharge bins are positioned according to the customer´s needs.
Capacities: 25 to 300t/h
