Front Raked Bar Screens (FRS) are multi-raked chain operated screens which are generally used as coarse and fine screens for medium and large sized water and wastewater treatment plants. Front Raked Bar Screen “FRS” is mainly consisting of bar screens, frame, dead plate and discharge chute which is equipped with multi-rakes and a counter wiper. By the help of multi-rakes very high screenings discharge capacity and low head loss is achieved. Also since the rakes are directly connected to the chain (i.e. no additional supporting structure) the installation height above level is very low even in very deep channels.  

                   

YMGS Mechanical Bar Screen has the below advantages:

• High Automaticity-can work continuously without any operation         
• High Separative Effiency
• Low Power Consumption
• No Noise
• Good Corrosion Resistance
• Self-Protection---when overload,it will give sound-light alarm and stop working automatically
• Can work based on different setting
• Self Control and Manual Control
• Self Cleaning

The bar screens are cleaned by the help of a ladle rake which is connected to an endless chain operating between two sprockets. The ladle rake is lowered down to the bottom of the channel in open position. It is closed at the bottom to clean the debris which is settled on the screen bars and moves up. The collected debris in the ladle rake is cleaned by a counter wiper when the ladle rake reaches to discharge point. Here the screenings are either removed to a container or a transporter for further processing.

• The depth of Ditch will be customized as the buyer's requirement.
• Diversion trench Length(mm)=1500+Hxctga
• Medium maxi temperature(°C)=less than 80 degree
• foot margin to discharging top mouth height H(mm)=400~1000m
