Pennsylvania-based Flexicon has released a new stainless steel weigh hopper with fill/pass valve for dilute-phase pneumatic conveying systems to suit virtually any chemical, mineral, plastics or food processing application. Suspended from three small-scale load cells, the gain-in-weight hopper delivers higher accuracy than loss-of-weight systems requiring higher-capacity load cells.
Single or multiple hoppers can be positioned along a common vacuum or positive pressure pneumatic conveying line for discharging of dry bulk solids into single or multiple process equipment, storage vessels or downstream use points by weight. Downstream of the last fill/pass valve, the conveying line can be routed to the original material source point or into a dust collection device.
