Roller Screen / Wobbler
For feeding and screening of problematic raw materials
The roller screen / wobbler is designed for the classification of coarse, wet, sticky and lumpy material. It is mostly applied in case of difficult screening conditions and perfectly suited for transporting the coarse lumps to the crushing installation. Our roller screen / wobbler fits to various feed materials, for example limestone, marl, mineral coal, lignite etc.
The synchronized shafts connected by chains and driven by a central drive are provided with several rows of rollers which convey the oversized material, while the fine material is screened out.
The earthy and clayey parts sticking to the oversized material are worked loose and also separated by the sinusoidal tumbling motion of the material.
Under each roller a scraper is installed to clean the roller surface during operation and to keep the screening efficiency.
