The variation of residency time of grinding balls inside a mill with n, in the case of grates present on the mill, while the ratio of the grates' size to the original balls' size is 0.5.
Grinding Calculation Formulas Firstly, I'm new to the grinding industry (IT Deptartment). I am writing a new program that does our calculations for us. I am stuck on figuring out Qprime. The Formula i have found is Q = Ae(Depth of Cut) * Vw(WorkPiece Feed Rate) / 60. However I am putting in some numbers to which i know what Q prime is, and I am ...
In the grinding process, due to the elastic deformations of grinding machine and grinding wheel, the ground depth of cut is smaller than the applied depth of cut. Consequently, the ground depth of cut has to be controlled in spark-out grinding process. However, the cycle time in spark-out grinding process is not easy to be estimated. From such a viewpoint, in this study, using …
