Comparisons of Corrugated Roller Shell and Dimpled Roller Shell
● The advantage of dimpled roller shell is the even wearing of ring die or flat die, but bad coil performance.
● Corrugated roller shell is of good coil performance, but the wearing of the die is not even.
● Closed ends corrugated roller shell is mainly used for making aquafeed. Because corrugated roller shell with closed ends can reduce slippage of materials when being extruded and offer resistance to plugging the die.
