FUNdaMENTALS of Design
in the design of bearing systems Whenever you think you have a good design, invert it, think of using a com-pletely different type of bearing or mounting, and com-pare it to what you originally considered. Why did some civilizations discover bearings and others did not? Those with bearings moved farther faster, and history has yet to stop.
Optimizing your SAG mill operationInternational Mining
The commercially viable and industry accepted alternate is a grate discharge trunnion supported mill or a grate discharge shell supported mill using pulp lifters. The only way to eliminate the problem of flow-back and carry-over of slurry and pebbles is by optimizing the design of the discharge arrangement.
Stainless-Steel-Mediated Quantitative Hydrogen Generation
A robust and quantitative gaseous hydrogen generation method has been developed in an effort to achieve efficient H2 generation derived from H2O. The present reaction could be achieved by a simple ball friction (milling) reaction of H2O using a planetary ball mill machine with a stainless-steel vessel and balls. It was mediated by metals as an element of stainless steel of the ball mill and

Milling Process, Defects, Equipment
End millingAn end mill makes either peripheral or slot cuts, determined by the step-over distance, across the workpiece in order to machine a specified feature, such as a profile, slot, pocket, or even a complex surface contour.The depth of the feature may be machined in a single pass or may be reached by machining at a smaller axial depth of cut and making multiple passes.
