Catenary Bar Screens

The Catenary Bar Screen is an extra heavy duty front cleaned, front returned bar screen.

This screen utilizes two (2) strands of steel chain that is heavier and has superior strength than any other screen chain. The Chain is suspended from sprockets located on the head shaft, the lower end of the chain forms a 'Catenary' loop.

Connected between these chains are counter weighted rakes.

On the return run, the chain is supported by structural members, allowing the chain and rakes to enter the channel, follow the path of the 'Catenary' loop, without the aid of guides or sprockets. As the rake enters the bar rack, the rake remove the debris, collected on the bar rack.

The bar rack contains trapezoidal bars that are efficient and clog resistant

As the rake exits the bar rack, it enters the dead plate where the debris is dewatered, and elevated to the discharge piont for deposit into a debris container or belt conveyor.
