UK: Flexicon has launched a weigh hopper with a ‘Fill/Pass’ valve for dilute-phase pneumatic conveying systems. The ‘Fill/Pass’ valve allows material to pass through the valve or to fill a hopper based on weight gain signals transmitted from load cells to the system's controller.
Suspended from three small-scale load cells, the bulk handling company says that 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 the 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.
