Address Process Non-Uniformity - Jenike & Johanson
Non-uniform processes can be the result of poorly operating equipment or system design. Unreliable flow through material handling equipment will negatively affect process uniformity. Common bulk material handling processes involve: Silos, bins, hoppers. Transfer chutes, conveyors. Drying, cooling, purging. Crushing, milling.
