• IMPACT OF PHYSICAL AND MECHANICAL PROPERTIES OF ROCKS .

    found that the increasing uniaxial compressive strength increased the time required for crushing. Toraman et al. (2010) conducted tests on laboratory jaw crusher and found a link between the crushing index and the impact strength index. Tosun and Konak (2014) developed a model to predict the energy consumption of primary and secondary crushers.
