OREANDA-NEWS. December 26, 2007.  Gubkin, public corporation “Industrial complex “KMAore”. On the first section of area №2 GSF at “Industrial complex “KMAore” public corporation preparatory work on installation of grate of fine wet screening “Stack Sizer” of the American company "Derrick Corporation" began. The grate has high efficiency of screening with high productivity in top size screening and good transportation.

Exploitation of new grate “Stack Sizer” will allow: - to increase the productivity of first-stage grinders up to 30% without loss of quality of concentrated product. At the present time the second stage of grinding is constraint of productivity growth because of its insufficient volume; - to provide manufacture of concentrated product by executing of the task to increase ore extraction by 10% in 2008; - to put out of operation one grinder of second-stage grinding at each section and this will result in reduction of consumption of cylpebs and reduction of electric energy consumption. In case of successful outcome of the experiment at the first section of GSF it will be applied at all the others.
