interior of what appears to be a factory or industrial facility

interior of what appears to be a factory or industrial facility. The primary focus is on a large, conical hopper or funnel-shaped structure, covered with white residue. A conveyor belt runs below it, collecting material from the hopper. The structure is supported by black metal beams. In the background, workers are visible in a wide-open room with multiple levels. They are moving around yellow bags, possibly filled with a material related to the production process. Some workers are wearing masks. The floor is covered in a layer of the same white residue as the hopper. Other industrial equipment is also visible in the background.
