Mike, this is one dirty job. In spending the day crushing mountain sides into gravel, dirty is our way of life. From greasing the equipment to crawling into the filthy clostrophobic crushers to change screens, we have learned how to cope with the lower echelon. The crushers sound like a perpetuating train wreck and the dust thrown up leaves us in a thick, heavy fog. Then to add insult to injury, we must pressure wash everything off the machines so that they can be safely mobilized to the next location...to do it all over again.
