The filter receiver of the pneumatic conveying system is mounted on load cells, enabling the system controller to stop the conveyor once a pre-selected batch weight, equivalent to that of one full bulk bag, has been accumulated.
Ein vom Bediener gesteuertes Schieberventil lässt die gewogene Charge mit hoher Geschwindigkeit aus dem Filterbehälter in den Schüttgutbeutel abfließen; anschließend wird das Ventil geschlossen und die nächste Charge gewogen.
“Weighing of batches independent of bulk bag filler allows simultaneous recharging of the filter receiver and replacement of filled bulk bags with empty bags, cutting overall cycle times up to 50 percent,” says Gill.
The REAR-POST bulk bag filler employs a cantilevered fill head that provides three-sided access to bag straps and is equipped with: inflatable collar to hold and seal the bag inlet spout, pneumatically retractable bag strap hooks, air displacement vent port, automated vibratory densification/deaeration system, inflator to expand empty bags, and powered fill head height adjustment.
Neben dem Filterempfänger und der Steuerung für die Dosierung mittels Wiegeverfahren ist das pneumatische Fördersystem mit einer Vakuumpumpe und Drehschleusen ausgestattet, die für die Integration in die bestehenden Prozessanlagen ausgelegt sind.
Other bulk bag filling-related equipment offered by the company includes: powered or gravity roller conveyors; forward-traveling, rear bag strap hooks; pallet-jack accessible bases; and patented TWIN-CENTERPOST models in industrial, food and USDA Dairy Accepted construction and finishes.
