Mechanical Rotary bar monitor is a committed unit intercepting sound waste from water, it can clean flotage in all designs instantly and continuously. When the h2o flows by way of the hole of bar monitor, the bar screen makes circular motion in correct route by reduction equipment, and intercepts solid waste from water. The bar monitor takes flotage up to the best. Most of flotage falls down by gravity, others cling into the hole of bar creen clear the bar sceen by reversal cleaning brush and uniformly tumble into screw conveyor. Every single group of bar display makes relative motion, so that bar monitor can make self-cleaning by chain wheel and keep track of. As the bar screen chain is enclosed, so it can clear the flotage in the drinking water immediately and repeatedly.
