With limited modifications such as removing inner helix/paddle lifters, rail track adjustable gas air injection and the addition of a cast able high alumina content refractory liner, this unit can now process 14 tons of precious metal bearing slags with every 24 hours of operation. Maximum operating temperature with current gas/air injection system is approximately 2,800 degrees Fahrenheit. This can be achieved in 35 to 40 minutes after loading and ignition. The high temperature refractory liner inside of this furnace is the best than can be obtained at any cost. The Cast able mix was composed with 90% alumina and rated for continuous operation at 3,200 degrees Fahrenheit. The value of the refractory mix alone exceeds a quarter of a million dollars U.S.
