MATERIAL COMPOUNDING. The dryer crystallisation system, and metering and conveying units must be tailored to the specific properties of the material being processed Special investigations allow the precise material properties to be established before a start is made on the project planing for a system. The results of the analysis are channelled into the planning so that the overall system can be implemented and commissioned more rapidly and at a lower cost. Product quality is additionally increased, together with the reliability of the process during the everyday operation of the system.
