500TPH Limestone Crushing Plant
Limestone has a relatively low hardness, with its Mohs hardness usually ranging from 3 to 4. Mohs hardness is a standard measure of the hardness of a material, which is evaluated by comparing the performance of the material in a scratch test. In this system, diamond has a hardness of 10, which is the hardest substance, while graphite has a hardness of 1, which is the softest.
