What Is Aggregate? Properties of Aggregates Aggregate ...

2020-7-4  Specific gravity or relative density of aggregate is a ratio of its density to the density of water. The specific gravity of fine or coarse aggregate is usually in the range of 2.2 to 2.8. While specific gravity values are used during mixture proportioning of concrete, density values are used to measure the yield of concrete and others.

Impact Crusher - an overview ScienceDirect Topics

A jaw crusher crushes only a small proportion of the original aggregate particles but an impact crusher crushes mortar and aggregate particles alike and thus generates a higher amount of fine material (O’Mahony, 1990). Gyratory crushers work on the same principle as cone crushers (Figure 4.4(c)). These have a gyratory motion driven by an ...
