the degree of hardness of basalt stone

Stone crusher plant details | Henan Deya Machinery Co., Ltd.

Apr 27, 20225.2 Limestone crushing plant equipment combinations. Limestone Mohs hardness is 4-5, which is very low, and the silica content in the stone is low, too, thus the abrasiveness to the crusher wearing parts is low. It is easier to crush due to the low hardness and brittle, the operational cost will be lower comparing with hard stones.
