Mogensen exceeds expectations in Chile

After 260 hours of commissioning and test running it has been established that the Sizer can consistently extract 280 tph of -4mm fines within the required specification from the incoming feed compared with the 200tph quoted initially. The combination of the probability screening principle of the Mogensen Sizer and the rock-on-rock crushing action of the Barmac unit has, as hoped, resulted in significant improvements in plant efficiency.
With the introduction of this equipment the plant is now producing sufficient within-specification material to enable the management to operate the plant with only two of the originally used eight grinding mills, which previously processed the incoming feed without pre-screening. The two remaining mills are achieving a 30% improvement in output with no increase in power consumption, because of the enhanced grading of the feed presented to them. A further benefit is that, with six mills in reserve at any given time, maintenance can be more efficiently planned.
It is reported that the most optimistic hopes of increasing the plant capacity, whilst at the same time reducing total power consumption, have been comfortably exceeded.
