Apr 01, 2020nbsp018332hence, the crushing behavior of weathered phyllite may be very different from that of normal granular soils. weathered phyllite fills vary in particle gradations and rock contents. herein, the rock is distinguished from the soil only in terms of the particle size, and it is defined as a block coarser than the soil matrix.
Typical gradations are near the 0.45 power curve but not right on it. generally, a true maximum density gradation exactly on the 0.45 power curve would result in unacceptably low vma. gap graded. refers to a gradation that contains only a small percentage of aggregate particles in the mid-size range. the curve is flat in the mid-size range.

Rock riprap preferred broken concrete and other rubble must control material quality and gradation shape neither the width or thickness of a stone should be less than 13 the length consider rock density denser is better angular rock is better than rounded edge
For crushers, make sure to change the settings and rock type, use add new rock type if needed save the new gradation, it will then be available to use specifications use add group to add a new specification group, later you can copy the specification to your new group, the group will be at the bottom of the list when it is created.
When trying to optimize a crushing circuit to produce mostly cubical aggregate, its important to consider the material being processed and the gradations an operator wants to produce. you have to consider the entire operation in order to achieve one production goal, that of optimized cubical aggregate.
