Oil Shale Crushing Process

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.
