The transported material enters the working area of the lift through a loading chute. The flow of material is regulated by a control valve. The material is collected by rubber scrapers, which are attached to the conveyor chain. Inside, the chain with the loaded scrapers moves through the body up to the discharge opening. The casing has a rectangular cross-section. Its cross-sectional area is divided by a wall into two chambers (the working and return chambers). After being lifted, the material is ejected by centrifugal force through the scraper into the feed hopper of the next technological device (separator). The chain with the empty scrapers returns to the bottom of the casing.
