    23/09/2014· Most of our work since 2000 has been in developing grinding mill foundations to avoid vibration and unacceptable deflections. On a recent project for a plant in Peru, the client was told by the mill vendor that there was no need to do a systems (dynamic) analysis on the mill foundations because the mills on that project were gear driven rather than being driven by ring motors (gearless

    After being mined, mills use small steel balls to grind ore smaller for further processing. To load and unload these steel balls, kibble systems are used. This provides a safe and easier way to charge mill chutes or inlets. Dynamic Engineering can design kibble systems to suit your unique mining operation.
