The Complete Guide to Crushed Stone and Gravel

2019-11-11  Crushed stone: If you hear the generic “crushed stone” term, it usually refers to stone that has a mixture of stone dust in it. This type of stone is best used for a base when heavy compaction is needed. As a result, it is typically used for the base of concrete and paving projects, foundations of structures, and driveway bases.

Analysis of the pick-up of crushed stone particles in a

2021-1-2  For crushed stone particles with a particle size of 5–7 mm, the pick-up mass was the minimum, which is attributed to the particle porosity and air permeability. With increasing feeding mass, the airflow velocity on the surface of the particles accumulated at the bottom of the pipe increases, and the pick-up mass of the particles exhibits a positive correlation with the feeding mass.
