In the quarry, crushing is handled in four potential stages: primary, secondary, tertiary and quaternary. The reduction of aggregate is spread over these stages to better control the product size and quality, while minimizing waste. The primary stage was once viewed merely as a means to further reduce stone following the blast or excavation ...

Oct 20, 2020The crushing-strength test is not practiced as a rule except on stone intended for building purposes. The fact is that most rocks have adequate compressive resistance for structural purposes. Crushed stone does not lend itself to the compression test very readily unless the sample is taken from the ledge rock before it is crushed.
