The cutting action of an auger differs from other coal cutting machines, such as continuous miners, in that it exploits the lower tensile strength of coal rather than overcoming the comparatively high compressive strength of coal. This makes augers more efficient in terms of the power needed to cut the coal. Note in Figure 2 the size of the cutting
Auger Sampling Systems. In an ideal situation, bulk materials are mechanically sampled from a moving material flow. Examples of ideal sampling locations include on a moving belt conveyor, free-falling in a vertical chute, or as material is discharged from a conveyor at a transfer point.
