JOY WetheadThe JOY Wethead continuous miner cutterhead incorporates a fine water spray behind each cutting bit of on the cutter drums. Acting as both a cooling and wetting agent, the water reduces the potential for frictional ignitions and reduces respirable dust levels. The water spray acts as both a cooling and wetting agent in order to address both issues at the same time. The sprays also provide lubrication that substantially improves bit life. The Wetheaddoes all this while potentially consuming less water than the standard miner dust sprays. The heart of the system is a back-to-back carbon-face water seal designed to last from rebuild-to-rebuild before refurbishment is necessary.
