Chip Washing

Chips are supplied in a continuous flow from the silo and enter the chip washer via a special inlet chute. As they fall into the wash water, they are agitated by a paddle wheel over a weir to the outlet. In this way, heavy contaminants are separated from the chips and eliminated through a sluice arrangement at the bottom of the washer. The floodgate empties into the ANDRITZ trash collecting screw which transports the trash material into a container for removal.

• Dewatering the material (free water and water on the surface)
• Cleaning off sand, dirt, and small stones
• Continuous material handling into the mixing screw or to the pre-steaming bin
