The solution had to deliver the performance of a large-scale system while remaining easy to move, with a modular layout of three configurable modules to adapt to different jobs. It also had to ensure efficient collection of material in big bags, provide particle size separation when required, and guarantee maximum safety when handling potentially explosive dust in an ATEX Zone 22 area. Key priorities included: SAFE ATEX HANDLING MOBILE LARGE-SCALE CAPACITY CONTROLLED DISCHARGE AND SEPARATION Fine car",
