Zanker Recycling has opened a 75 tons-per-hour (tph) Demolition Debris Materials Recovery Facility (MRF) located at the company's San Jose operation. With the addition Zanker Recycling has more than doubled its capacity to process this type of material. The system was designed, manufactured and installed by Eugene, Oregon-based Bulk Handling Systems (BHS).
The company expects to recover upwards of 90% of inbound materials. Sizing and density separation are fundamental to the system's success. After primary screening to remove large items, two BHS Debris Roll Screens prepare two size fractions for air separation. After sizing, four Nihot Single Drum Separators (SDSs) separate by density. The first SDS units remove aggregate material, such as rock and brick, while the second Nihot units extract wood from lighter material.
