- Process Of Crushing Rock In Aggregate
During mining of rocks, explosive is used. After expulsion of the rock, it is carried to the crusher. Initially, the large rocks are broken into pieces using the impact crusher. These rock pieces are fed to the jaw crusher to bring into aggregate form. The vibrating sieve is used to separate the aggregates of different sizes.
