RRS Clearing wheel rotary valves

Scraper wheel rotary valves are used for caking or slightly sticky bulk materials. The scraper wheel scrapes out the cells of the rotor and thus ensures smooth conveying of the bulk material. The scraper wheel ensures a forced clearing of the cell wheel and reliably scrapes the rounded chamber plates. The scraper wheel is driven by a spur gear. In addition, our scraper wheel sluice has a cleaning opening that allows easy cleaning and maintenance of the scraper wheel sluice without disassembly.
