At ConMat Construction I worked on a rock crusher plant. I was responsible for several key areas of the mill which included making sure there were no problems or potential hazards such as rips, tears, or holes in any of the belts, rollers, or screens. I greased the whole plant including rollers, jaw crusher, and cone crusher. I was responsible for the maintenance of the bobcat that I operated, I checked all the oils, hydraulic fluid and coolant and fueled it every morning before getting started for the day. I used the bobcat to help clean up all of the overfill rock and dirt that slipped through the screens and put it back in the plant to be used for its intended purpose so we could minimize waste, and on occasion I ran the plant while other operators were needed elsewhere.
