Project Notes

Customer reported that oil was leaking from front crankshaft oil seal.  Oil seal needed to be replaced.


Many different minerals and solid aggregates are mined today. Quarries are an above ground style mine. Rock is removed by heavy equipment that employs blasting methods. The rock is broken down into sizes that fit the desired crusher. Some gravels go through more than one crusher for proper sizing. Electric conveyors move the aggregate from crusher to crusher or to finish piles. Mines that are located in areas the electrical grid does not support utilize equipment that uses high voltage and amperage provided by diesel generators. Large portable generators in sound attenuated enclosures can be moved from location to location in most any mining application.
