2. Metering Feeders Bag massagers are used to aid the consistent flow of difficult materials from a Bulk Bag and are located either in the base of the support dish, at the corners or on the side frame. They are actuated by pneumatic cylinders and their position and frequency of actuation is fully adjustable. They are particularly effective where storage of bags has created a compaction problem, when traditional (and noisy!) vibration may cause further compaction and hinder discharge. 3. Spout Stretcher (patented) Using our own flexible screw conveyor technology, or proprietary equipment, we are able...
