For the separation of coarse particles Rotary screen of Leiblein

The rotary screen is a drum sieve loaded from inside for separating suspended solids, particles and fibres from liquids, process water and waste water. 

The rotary drum can be equipped with different types of sieves or filters like perforated metal plates, wedge wire screens and fabrics. This leads to a wide range of applications for various types of mediums. 

So it is also possible, for example, to treat hot washing and process water. It can be used as a washing drum for the dewatering of special products as well

Effective separation even at high throughputs – technology made by Leiblein Functional principle of the rotary screen

The feed stream is led into the sieve drum (❷) via the inlet pipe (❶) and is spread evenly on the drum surface. The actual sieving process takes place inside the continuously rotating sieve drum.

The untreated water flows from the inside outwards through the filter drum into the collector for the clear water (❸).

The solids are retained by the drum and carried to the solid output (❺) by a screw conveyer (❹) where they fall into a sludge tank. The rotating sieve drum is cleaned continuously by a brush roller (❻). In addition, an outside of the drum mounted sprayer with nozzle assembly (❼) is used for rinsing.
