Bucyrus has launched wethead cutting technology for its series of continuous miners.
According to the manufacturer, the wethead design is unique because of the flexible split gearcase of the 25M series. Water passages are large and with the use of check valves, water is able to flow to the cutter drums through both the left and right gearcases or through a single case.
The wethead comes with a 2-inch thick drum shell, rifle drilled water passages through the shell, carbon-faced seals, corrosion resistant ports and components and seal cartridges that are accessible without opening the gearcase reservoir.
Any water leakage is diverted to the outside of the gearcase so that seal failure will not damage the gears and bearings. Also, with the proper maintenance, the cutterhead can be run wet or dry.
