These the reasons why this coal quarry has added an MB Crusher unit to reduce the overburden to the grade needed to upkeep the internal haulage roads, daily.
This unit is a jaw crusher, compact and versatile, and it operates by using the excavator hydraulic supply. One operator and one machine alone can upkeep the quarry road system. No extra personnel is involved, no acquisition of extra material.
How is the overburden grading done?
The output of the MB Crusher machine is fully adjustable from 40mm to 150mm and the size change can be done anywhere, it involves unscrewing some bolts, adding or removing sizing shims and screw back the bolts. No need to take the machine to the workshop. The same principle is applied to the unit maintenance, it is designed to avoid having to be taken to a specialized service centre, the operator can do it wherever.
