density after crushing rock

Standard Weights for Crushed Rock Per Meter Hunker

Solid rock is estimated at 25 to 3tons per cubic meter If rock is crushed into uniform sizes the presence of open space between the particles causes the load to be lighter -- approximately 16 tons per cubic meter Mixed sizes of crushed rock can range from 16 to 22 tons per cubic meter...

The Density of Common Rocks and Minerals

Jan 23 2020 0183 32 The densities of rocks and minerals are normally expressed as specific gravity which is the density of the rock relative to the density of water This isn t as complex as you may think because water s density is 1 gram per cubic centimeter or 1 g/cm 3 Therefore these numbers translate directly to g/cm 3 or tonnes per cubic meter t/m 3...
