Zochem has recently added the JS Iris Diaphragm Valve Bulk Bag Discharge Control system, allowing us to precisely control the transfer of zinc oxide from large bulk bags to smaller bags and containers to meet specific customer needs. Bulk bags can weigh anywhere from 1,000 to 4,400 lb. Without this type of iris control, it can be difficult or impossible to control the flow from a bulk bag.
Normally, a bulk bag is opened and allowed to flow until empty. Now, when a customer requests a quantity of a batch formula, we can efficiently deliver the zinc oxide in the exact weight required. With less waste and greater operational efficiency, we meet customer expectations for order size and turnaround time. See a demo at the following videos:
