The dolomite crushing and sand making production line has the advantages of high degree of automation, high crushing efficiency, low operating cost, energy saving and environmental protection, and fine sand making size. Dolomite has a Mohs hardness of 3-4 and a specific gravity of 2.85-2.9. It is a sedimentary carbonate rock.Web
Dolomite is slightly harder than calcite, scoring 3.5- 4 while calcite scores 3 on the hardness scale. If you're unfamiliar, the Mohs scale of hardness determines a stone's hardness by measuring how scratch-resistant it is. According to this scale, a stone can scratch any other mineral with a lower score.Web
