Mining equipment supplier, HPE Steinmuller, has installed the 20~(th) unit of its locally designed and manufactured HPE Mudgun, at ASA Metals chrome smelter in Machadadorp. The taphole equipment includes the mudgun, which is used to close the taphole, and a drill for drilling the taphole close to the furnace wall.The mudgun offers low cost, low maintenance and safe servicing of tapholes in submerged arc furnaces and is driven using a fire-safe hydraulic system operated with additive-free water for lubrication. This effectively eliminates the problems of fluid stability and fungal growths common in emulsion-based hydraulic equipment.
