Mechanical Bar Screen

Mechanical Bar Screen The equipment used for safely removing coarse & fine contaminants (dust, garbage etc.), in sewage treatment by screening, that are big enough to damage plant equipment is the bar type mechanical screen used at the water intake structures of treatment plants.

Rake bar type screens are categorized into two classes as mechanical screens and manual screens according to working principle. Mechanical screens are called as fine screens and coarse screens according to the openings between bars.

Besides wastewater treatment plants; mechnical screen is used in pumping stations and water supply structures.

The equipment is mounted in open channels by an angle of 70-75 degree.

While screens having 15 mm or less bar opening are called as fine screens, the screens having 15 mm or more bar opening are called coarse screens.

Smaller than 5 mm fine particles you can look at our fine screens; sieve bend screen or rotary disc screens.

Mechanical screens produced by City Makine can be operated in a level- or time-adjusted manner through a PLC automation panel.

Mekanik IzgaraThe automatically operated mechanical screen separates coarse contaminants from wastewater at the inlet channel and discharges the separated contaminants into conveyors or garbage containers, without the need for manpower.

Material Options
