  "abstract": "This disclosure describes an arrangement for suppressing dust at bulk material transfer points. It employs a staged enclosure around the material drop zone, paired with an induced air balance system. The enclosure design promotes staged particle settling while skirt seals minimize uncontrolled air ingress. An air extraction system maintains a net inward airflow, preventing dust escape. The induced air volume is determined by material flow characteristics and drop height, ensuring efficient capture of airborne particles. Adaptations for sticky materials are also detailed, addressing potential accumulation and flow issues within the system.",
