Using the Diamondback Technology® System. Here is Why? Recent development in characterizing powder flow properties show promise in predicting the success or failure of tableting presses, and related powder processing and handling equipment, with untried formulations. Derived from basic powder flow properties, the recently developed flow indices quantify various basic powder flow phenomena related to blenders, feeders, chutes, bins and tableting presses. The indices technique, although developed specifically for predicting flow in hoppers, feeders and chutes, shows great promise in the broader application of characterizing the theological properties of various formulations. Because the indices area combination of basic properties, they can be extrapolated to predict the success or failure of new formulations in existing processing system.
