  • IMPACT OF PHYSICAL AND MECHANICAL PROPERTIES

    2015-5-6 · Tosun and Konak (2014) measured power consumption of jaw crusher during crushing of limestone rocks. The specific crushing energy for the limestone rocks ranged between 1.012-3.298 kJ/kg. According to Refahi et al. (2009), the specific crushing energy for igneous rocks (granite) was around 1.5 kJ/kg while it was less for limestone, i.e. around 1.0 kJ/kg. Besides the measuring, the specific energy consumption was determined using numerical simulations. Refahi et al. (2009) also used a discrete element method to model the crushing behavior of some rocks with different mechanical properties in a laboratory jaw crusher. According to the authors, there is a difference between the Bond and wall energy varying from 2.7% for the lowest-strength rock (spherical limestone rock) to 26.5% for the hardest rock (spherical biotite rock) and from 37.8% for the lowest-strength cubic rock to 56.7% for the hardest cubic rock.
