:: Innovations in Crushing Technology
Last month's Comminution '16 highlighted the many innovations that are taking place in comminution, the most important, yet the most energy intensive, area of the mineral processing flowsheet.
Grinding is evolving and changing fast, with innovations in high pressure grinding rolls and stirred mills threatening to make the tumbling mill, which has been a stalwart for well over a century, obsolete.
But innovation in crushing has not been so rapid, and most of the developments reported in this area have been in control, simulation and optimisation of crushing circuits, rather than in new developments in the machines themselves. Indeed only two years ago, at Comminution '14, Tim Napier-Munn in his keynote lecture observed that in the 1970s Professor Klaus Schonert showed that the most energy-efficient way to break a rock was to place it between two opposed platens and load it until it fractured in tension, this simple mechanism seriously limiting the options regarding real innovation in the comminution process. To support this view he showed a slide of one of today’s cone crushers showing that in all material respects it is identical to a cone crusher manufactured in the 1930s.
