The purpose of the aggregate processing plant is to prepare the rock or mineral in a form suitable for its use as aggregate, commonly defined in terms of particle size and size distribution, particle shape and mechanical properties, e.g. compressive strength. As a result, the process plant usually contains only the unit processes
Figure 11.19.1-2 is a flow diagram for industrial sand and gravel processing. The mined rock is transported to the processing site and stockpiled. The material then is crushed. Depending on the degree of cementation, several stages of crushing may be required to achieve the desired size reduction.
Gravel processing through rock-on-rock crushing and upgrading Gravel processing via impact technology using rotor centrifugal crusher for selectively reducing size of off-spec gravel fractions, increasing the crushed face count and destroying brittle rock conglomerat.
