Angle of Repose

Angle of repose is another important physical property used for characterization of the bulk of particulate foods such as seeds, grains, flours, grits, and fruits. When granular solids are piled on a flat surface, the sides of the pile are at a definite reproducible angle with the horizontal leveled surface (Fig. 3.8).This angle is called the angle of repose of the material.

How Cement Mixers Work

Most of the mixer fleet, especially older batch model trucks, uses a simple tip-and-pour method to get the concrete out of the mixer. A chute attaches to a port and the concrete oozes (or pours, depending on its consistency) out of the mixer to the project. Usually, the driver of the truck operates the machinery and aims the chute.
