The Debris Roll Screen

Bulk Handling Systems, Inc. (BHS) began designing and manufacturing conventional disc screens for the Wood Products and Pulp & Paper Industries more than 23 years ago. In 1990, BHS recognized the need for a disc-like screening device in the recycling industry. The conventional disc screen was not suitable for this environment due to excessive jamming, however. BHS developed the solution.

The Debris Roll Screen (DRS) employs a patented shape and configuration that allows it to process municipal solid waste, greenwaste, biomass debris, construction/demolition, wood chips, compost, wood debris, bark, aluminum and other miscellaneous materials with greater proficiency than competitive separation devices. The DRS creates a unique wavelike action that agitates the incoming material as it is conveyed forward. This agitation releases smaller materials through the screen openings and is accomplished without vibration or blinding. Unlike the conventional disc screen or starscreen, the DRS design greatly reduces the possibility of jamming or seizing during operation. The resulting benefits of the DRS have proven effective in the Wood Products industry as well.

When compared to trommels, vibratory, or finger screens, advantages of the Debris Roll Screen® include high capacity, small footprint, self-cleaning action and low operational and maintenance costs. Several hundred Debris Roll Screens® are operating throughout four continents.
