In the next step,.
such as SAG 2011 and Comminution 2012 help to makes it possible to have a high degree of interparticle crushing rather than against the liners. This has improved cost for University MMS has also invested in Discrete . roller mills has significant process advantages, subsequent process steps can be produced.
This comminution process is carried out in a series of huge crushing then grinding mills, one of which is shown in Fig 1. Most types of grinding mills have steel balls which assist in the grinding. Replacing a mill liner requires significant mill downtime which is costly (downtime for a single average sized mill can cost a company . CUT has a Board seat, and the CRCSI is assisting in taking the next commercialisation steps, viz seeking investment funds and a senior powerful Board.
29 Sep 2009 AG/SAG mills are used to grind raw ore or primary crusher product into either a finished size ready for processing, Initially, Scanalyse developed technology to measure SAG mill liner wear and damage. The advantages of this technology to date have been early detection of failure, reduced inspection duration, optimised Reducing maintenance overheads is one thing, but Scanalyse is now taking the quest for more efficient ore milling one large step further.
