PROPERTIES OF GEOMETRICALLY CUBICAL AGGREGATES

The process and mechanism of aggregate cubisizing within the rock on rock impact crusher is unique as the crusher was effectively tuned to reshape and treat the much finer fractions. In this research, the crushing technology effectively crushed, trimmed and churned up normal aggregate to produce coarse and fine aggregates. This study

Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete. After harvesting, aggregate is processed crushed, screened, and washed to obtain proper cleanliness and gradation.
