The well-known FSM filterband screens are installed in many different places around the world, under varying conditions. Everywhere, this screen has achieved very good results with very high collection levels and a high level of operational reliability.
Perforated, moveable steel panels automatically create a mat of screen material which is removed from the filter screen by means of brushes located at the top of the screen. Accumulated screenings are then collected in a conveyor and led on to screen material washing.
Upstream and downstream levels at the screen are determined either through ultrasound or a stick electrode. Once the water line exceeds a predetermined value, the screen and the cleaning brush are activated and solenoid valves facilitate water supply to the water-jet unit on the screen.
The construction of the filterband screen, featuring a carrier on every fifth filter element, prevents the accumulation of liquid matters by the inlet in front of the screen. The steel filter is pulled by chains and slides on plastic rails mounted on the machine frame.
FSM filterband screens are available with a width from 300 to 3,000 mm and with an ejection height of up to 11,000 mm. The filter panels are delivered with gauges that are tailor-made to customer needs, from 2 to 12 mm.
