Used Washing plant drier: KREYENBORG IR-Clean C-180/540-270 of 2022

Material: PE,PP Flow rate: 800 kg/h Max. working pressure: 250 bar Pressure loss: 100 bar Max. operating temperature: 240 degrees Number of filters in production: 2 Filtration area per filter: 515 cm2 Diameter of the circular screen: 200x300mm Hydraulic pump type R

Double-piston backwash screen changer for continuous operation Normal operation : Two holes in the screen (100 %) in the process Backwashing : One hole in the screen (50 %) in the process Screen change : When changing the screen, one of the screen holes (50%) is removed from the process so that one screen hole (50%) remains in operation. Output of the extruder : 840-1900 kg/h Screen diameter : 200mm Screen cm2 : 2x314 K-SWE/RS is suitable for most processes and materials. It can be used in composite, film, tube, plate and pelletizing applications. It can handle processes with a high contamination ratio (recycling) and allows the process to continue without shutting down the system when changing the screen. Features. Backwash function. Flow channels optimized by rheological data. Wear-free metal sealing system: no additional sealing required Easy integration into line controls. It includes a complete protection system that offers maximum safety for operators. Advantages. Proven spare parts cost reduction thanks to the integrated self-cleaning (backwashing) process that allows the screens to be used over and over again Fully automated backwashing and ventilation procedure (by SPS) for less operator intervention Significant reduction of operational costs (screen and labour costs) through the use of up to 100 backwashes Normal operation The heated steel housing allows the use of two screen bearing pistons, which contain one screen gap per piston. The melt flow is subdivided into two flow paths and runs through each of the two screen pockets. Screen change The screen bearing piston with the replaceable filter element is removed from the housing so that the screen pack can be removed from the piston and replaced with a new filter element. When the screen is changed, the screen gap of the other piston remains in the production position, without interrupting the melt flow. Fifty percent (50%) of the filter area will still be used for filtering. The special ventilation procedure prevents air from entering the process after the screen has been changed. Backwashing If the chosen pressure differential increases due to contamination of the filter screens, the piston automatically moves to the backwash position. The subsequent process is not adversely affected. By reversing the flow within the screen changer, the contamination of the screen pack is directed out through a chute. The screen pack is fixed inside the screen retainer.

Hydraulically actuated Screen Changer for discontinuous operation Screen Changer for discontinuous operation Type HS-Y-116 Suitable for all polyolefines as well as many technical polymers Discontinuous melt filter. The extruder has to be stopped momentarily (approx. 4 min.) for the screen change. Piston is moved out of the housing hydraulically (the screen bearing piston remaining in the housing, blocks the flow channel). Once the new filter medium is inserted, the screen bearing piston is moved back into the operating position. Extrusion Output: 200–330 Kg/h Screen Filter Diameter 116,3mm / 105cm2
