The height of the pendulum is raised until the energy is sufficient to break the specimen (Bond, 1947), and then the crusher work index (CWI) or impact work.
Based on a large number of tests, Bond introduced a working index or comminution parameter that represents the resistance of the material to crushing and grinding. Characterization of rocks for selection of crusher can be done in different ways, and the most commonly used is Bond work index (Tavares and Carvalho 2007).Jan 01, 2016 In conventional work, Bond’s work index is usually accepted as the measure of the net specific energy required for comminution. Klymowsky and Liu [13] found that Bond’s work index was not quite applicable in the case of the HPGR as it was determined using a tumbling mill where repeated impact and grinding forces were responsible for size.
Aug 09, 2019 Development Impact Bonds (DIBs) finance development programs with money from private investors who earn a return if the program is successful, paid by a third-party donor. The outcomes to be measured are agreed upon at the outset and independently verified. With greater focus on outcomes instead of inputs, DIBs create space for innovation, local problem-solving, and.The work index is the comminution parameter that expresses the resistance of the material to crushing and grinding.
