Hi community, since a long time I’m pondering about two topics that interest me. Stones / rocks and their industrial processing. If I want to cut rocks or slice stones in small pieces I have to use large machines, the energy consumption of such stone cutting machine is way too high for somebody who would just start to cut / slice rock. So, my question is: Do you have any ideas, thoughts or know about eco-friendly techologies which are energy efficient for cutting rocks into small slices? Every input regarding this topic is welcome.
