We developed this integrated bag-type purification equipment to match the combined crushing and screening unit for highway projects, aiming to adapt to working conditions featuring large flow rate, high dust concentration (dust content ≥1000 g/m³) and irregular dust emission. After purification, the exhaust gas meets the particulate emission standard ≤30 mg/m³ for Class II and III regions specified in GB16297-1996. Appraised by research institutions and end users, all technical indicators of the product satisfy design requirements.

This dust collector boasts high dust removal efficiency, low maintenance workload, large handling capacity and reliable performance with attractive appearance. It integrates two major functions: gas purification and material classification. In particular, it enables adjustable control over 200-mesh (0.075 mm) fine dust contained in finished aggregates (0–4.75 mm), limiting the content of powder finer than 200 mesh (0.075 mm) within 10%. This effectively improves the quality of finished aggregate, while cutting energy consumption by 50% compared with traditional powder separators.
