* Small water turbines rarely have efficiency better than 80%. Generators' efficiency of ~ 90% and power will also be lost in the pipe carrying the water to the turbine, due to frictional losses. A rough guide used for small systems of a few kW rating is to take the overall efficiency as approximately 50%.

Ball Mills

Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced.

8 Ways You're Killing Your End Mill

07-02-2018While traditional roughing is occasionally necessary or optimal, it is generally inferior to High Efficiency Milling (HEM).HEM is a roughing technique that uses a lower Radial Depth of Cut (RDOC) and a higher Axial Depth of Cut (ADOC). This spreads wear evenly across the cutting edge, dissipates heat, and reduces the chance of tool failure.
