In plastics processing applications wherever many different types of materials need to be delivered to many processing machines
All receivers are connected on the filtered air side to a common blower with secondary filter. Machine-related, the feed access is coupled manually or switched over automatically. On activation of the automatic level monitor in the outlet, the angle valve on the filtered air side opens and the outlet flap closes.
The vacuum in the system transfers the bulk material (granulate) via the conveying line into the receiver. The delivery interval is terminated when the level reaches the "full" indicator in the receiver. Once the conveying interval has elapsed, the outlet flap opens and the bulk material passes into the storage container of the processing machine.
The procedure of the individual receivers signalling specific product requirements is monitored by the electrical control system and the receivers are controlled accordingly.
