Possible Usage of Crushing Buckets in Oil Shale Mining
2015-3-6 · the crushed rock. The principle of oil shale separation in a crushing bucket is based on the fact that oil shale has smaller compressive strength than limestone. Compressive strength is the main indicator of crushability of a material [[13]]. Compressive strength of oil shale is dependent of surface hardness, cracks and moisture.

Abstract. Heat and mass transfer between gases and oil-shale particles are both important for all proposed retorting processes. Past studies of transfer in packed beds, which have disagreed substantially in their results, have nearly all been done with beds of regular particles of uniform size, whereas oil-shale retorting involves particles of diverse shapes and widely ranging sizes.
