The ordinate of point B is called the yield stress by analogy with the response of concrete samples. The maximum ordinate of the curve (Point C) that marks the transition between strain hardening and softening is called the unconfined compressive strength of the rock and is denoted as,Grinding and Finishing - me.iitb.ac.in,Grinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2.

BWI is an intrinsic characteristic of rock grindability, representing the specific energy for grinding rock when the feed size is 6 mesh and the product size is 100 mesh. This study used a laboratory Bond ball mill consisting of a cylindrical steel jar and a 70 RPM motor to derive BWI.(PDF) COMPLETE LECTURE NOTES ON ROCK MECHANICS,Rock mechanics deals with the mechanical properties of rock and the related methodologies required for engineering design. The subject of rock mechanics has evolved from different disciplines of applied mechanics. It is a truly interdisciplinary subject, with applications in geology and geophysics, mining, petroleum and geotechnical engineering. x Rock Mechanics and Rock Engineering Rock,Evaluation of mechanical rock properties using a Schmidt,,cRock Mechanics Institute, University of Oklahoma, 100 E.
