May 28, 2019 · The grinding parameters have a cross effect on grinding efficiency and grinding effect. For example, the effects of finishing time, oscillating frequency, single feed and linear velocity on surface roughness are more complied. In the grinding process, when the parameters are at extreme values, the best results are usually achieved.
The effect of grinding additives on breakage rates is also studied. In general, breakage rates increase for coarse sizes and decrease for fine sizes with an increase in the fines present in the mill. Such variations have strong impliions in closedcircuit grinding. Keywords breakage rates, milling, wet grinding, dry grinding Disciplines
In some grinding appliions, the use of an oil is impractical and a waterbased fluid must be chosen. when this is the case, other measures can be taken to reduce the likelihood of thermal damage. The temperature of the grinding fluid, for example, has a pronounced influence on its heat removal capability.
