compressive strength minerals

Estimating compressive strength General rock failure criterion can be reduced to a few parameters dependent on lithology m and the uniaxial compressive strength C 0Lithology is commonly derived during log analysis so m may be estimated Table 1What is needed still is an initial measure of rock strength provided by C 0 C 0 can be estimated from porosity or sonic velocities but many ...As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan.
