Black Diamond Coal Crushing Machines

Oct 06 2020 Rated 4 out of 5 by JimHOH from Black Diamond AbrasivesSand Blasting media This is a very good sand blasting media but you need a 14 nozzle and a large air compressor to supply air Most of the info that I have gotten says you need at least 80cfm to use the 14 nozzle but I have been able to use it for short periods with 220cfm compressors
