concrete sand mining process

In the rotary kiln, first the carbon dioxide is driven off of the calcium carbonates, then the raw material is fused at a temperature somewhere around 2,700 degrees F. The discharge from thekilnis called clinker, as it resembles small rocks or residue from a blast furnace. The clinker is the cement in "lump" form.
