The sand must be of proper gradation (it should have particles from 150 microns to 4.75 mm in proper proportion). When fine particles are in proper proportion, the sand will have fewer voids. The cement quantity required will be less. Such sand will be more economical. Demand for manufactured fine aggregates for making.
Crushed sand can be produced with our rotor impact mill (type RPM) or rotor centrifugal crusher (type RSMX). Both machines operate based on an impact principle and feature a vertical-shaft rotor. In both cases, this ensures high yields of sand, excellent cubical shapes and the ability to optimize the grain-size curve of the.
