ENTA - Model IFD -Internally Fed Drum Screens
Internal flow drum screens (IFD) which are produced for screening of the solids prone to settling, are in the group of fine screens. IFD; is a drum made of perforated metal sheet or mesh screen wire and consists of a bearing system, water distribution weir and water spray mechanism. By its fully closed structure, some problems like odor, spring etc. completely prevented. Screens are made from the material of stainless steel, epoxy painted or galvanized cover carbon steel. Screening ranges change between 10-80mm, and screen hole diameters change between 250pi-2mm.
Drum screens separate all the solid particles bigger than the screen space from the liquid which will be filtrated. By its operation principle, it keeps the long fiber wastes, grit and grease at the pre-treatment and processes and gains advantage.
Wastes are transferred continuously to the discharge part with the turn of the drum. From this part, they are poured to the conveyor or the transfer container which will be stocked. Drum screens are fully closed constructions. They do not cause any problems like odor and splashing.
The energy consumption is very low and its cleaning and maintenance is easy. The surface of the screen is designed for being cleaned with the pressured water or hot water as appropriate to the process.
