In fact in the same application a Vertimill174 has 50 less footprint than a ball mill Lower operating cost Vertimill174 is an energy efficient grinding machine They tend to grind more efficiently than for example ball mills with feeds as coarse as 6 mm to products finer than 20 microns This provides up to a 40 higher energy efficiency. 4695
determining the mill size, the need for variable speed and the characteristics of the electrical system of the plant. Comparison of Drives Systems for Grinding Applications The question what drive system is optimal for SAG and ball mills is project specific and depends on the plant layout and the design of the grinding
ABBs GMD is the most powerful mill drive system in the market to power semiautogenous (SAG), ball and autogenous (AG) mills, This workhorse for grinding operations combines a robust, servicefriendly and fit for purpose design to provide highest throughput, reliability
Technologies for extraction and processing, including gearless mill drives (GMDs) and gearless conveyor drives (GCDs), help operators save energy and achieve greater throughput at large mills with higher grinding capacities. When big data is also applied, this lowers costs using preventive and predictive maintenance.
