Operating principle of Chain Scraper Esmil Probig

4-shaft scraper (collecting bottom and floating sludge)

Chain-and-flight scrapers convey the bottom sludge into a hopper and the floating sludge into the scum pipe.

3-shaft scraper (collecting bottom sludge)

Chain-and-flight scrapers convey the bottom sludge

2-shaft scraper (collecting bottom sludge)

Chain-and-flight scrapers convey the bottom sludge into a hopper.

2-shaft scraper (collecting floating materials)

The floating materials are pushed using a chain-and-flight scraper over a ramp into the scum collecting channel.
