Drum Screen PWL TanFlow TFS for separation of pulp in sugar industries

5 Mar 2014

IMG_0830The externally fed drum screen PWL TanFlow TFS is able to separate heavy loads of pulp in sugar industries. PWL drum screens convince through reliability and efficiency in continuously running processes.

Within the inlet chamber the incoming medium is homogenized and the flow velocity reduced. The dammed up water passes a weir and runs through the wedge wire sieve drum while the solids are picked-up by the rotating drum and transported to a scraper. Being statically dewatered they are removed from the drum.

At the bottom of the drum the water enters, thus causing a wash-back-effect which serves in addition to clean the sieve. The outlet chamber is equipped with a discharge pipe. In addition to the scraper, there is a spray bar inside the drum which operates in intervals. If necessary, the cleaning effect can be increased with hot water.
