Sand and gravel was $7.65 per ton - varying depending on location and grade from $3.50 per ton to more than $15.00 per ton loaded on trucks at the mine. The average mine produces approximately 200,000 tons per year, with crushed stone mines producing an average of 350,000 tons per year and the average sand .
view moreCrushed 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 final product.
