Jan 21, 2017. #5. The trick to doing something like that will be to have the pivot under some tension, not much but not freewheeling, use the smallest diameter endmill possible to create your feature, and keep your depth of cut low. Sharp endmill, and HSS will likely hold up better than carbide as you will have some back lash, compared to a ...

Based on experience, mill-liner designs have moved toward more open-shell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebble-crushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of 2.5:1 and 5.0:1.
gold mines is 85 kg per day per mill!, and results in a total annual usage of 20 kt of metal at a cost of about R40 million. The total energy! used in milling is 2400 million kilowatt-hours at a cost of about R140 million. It was felt that the use of more suitable materials for mill liners and improved design could considerably reduce
The critical speed, Nc, in revolutions per minute, is a function of the mill diameter, D, expressed as: Nc = 42.3/√D (meters) or Nc = 76.63/√D (feet) In practical terms, one must assume some mill diameter, usually about 150 mm (6 inches) less than the mill inside shell or nominal diameter, that allows for the difference between the mill ...

Greatly accelerated liner wear due to high-energy impacts on the liner. For a 5m diameter mill these will be in excess of 8m.s-1, for a 10m diameter mill these exceed 12m.s-1. This causes high chrome liners to spall and crack and they may even fracture. This can reduce liner life from a year to less than a few months.
