Fill/pass valve controls pneumatic transfer of dry solids

Related tags: Weight

A new weigh hopper with fill/pass valve for dilute-phase pneumatic conveying systems has been introduced by Flexicon. 

Suspended from three small-scale load cells, the gain-in-weight hopper is said to deliver higher accuracy than loss-of-weight systems that require 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.

The system’s controller weighs a batch by changing the position of the valve, which diverts conveyed material into the hopper. As the hopper fills, load cells transmit weight gain information to a programmable logic controller.

Once the batch weight has been reached, the valve redirects material away from the hopper. The controller then actuates a slide gate valve to open, discharging the weighed batch.
