The big bag connection system BBA provides an essential interface between product feeding and the production process itself.
It is used for low-dust docking and secure discharging of big bags, including those with an inlet, in the food, pharmaceutical, chemical and plastics industries.
The big bags are hung on mobile lifting gear and transported to the corresponding big bag connection system, where are they are set down on a support plate. The big bag outlet, which is still closed, is pulled over the inner pipe of the connection system and clamped firmly in place by manually lowering the pressure disc.
If wrinkles form in the outlet when the big bag is connected, the double-pipe design provides additional protection against escaping dust. Any product that escapes is returned to the process via an annular gap between the outer and inner pipes. The system is sealed using static gaskets. The closure cord is then opened and discharge into the subsequent process begins. The entrained air and any dust which arises are drawn off at the aspiration connection.
For non-free-flowing bulk materials, a vibration discharge can optionally be provided. On request, the big bag connection system can be fitted with a low level indicator to enable the big bag to be replaced promptly and avoid production downtimes.
