This batching system was built for a manufacturer of engineered refractory products. They required an automated system to batch and mix seven ingredients. The customer had five existing exterior storage hoppers which where retrofitted with new feed screw conveyors. The new screw conveyors transported their product into a five-ingredient net weigh hopper. In addition to the materials fed into the net weigh hopper, there are two Loss-of-Weight Bulk Bag Unloading stations which are able to simultaneously feed the desired amount of material. Both the net weigh hopper and the Loss-of-Weight Unloading stations feed onto a collection conveyor for transport to the existing industrial mixer.
A typical batch consists of 500 lbs. from the Loss-of-Weight Unloading stations and 1200 lbs. in the net weigh hopper with an accuracy of +/- 0.2%.
