Abstract:
The durability of extruded, uncured animal feed pellets is measured by disintegrating the pellets in a test chamber by means of a rotating blade powered by an electric motor. During the test, the rotating blade is maintained at or near a constant rate of rotation and the time over which an increase of power is necessary to drive the blade at constant rotation is sensed to determine the durability of the pellets.
