There are three main physicochemical transformations in the rotary kiln furnace The first one is the evaporation of free moisture Then the thermal dissociation The primary pyrometallurgical route to produce ferronickel from laterite nickel ores is the Rotary KilnElectric Furnace (RKEF) process In the RKEF process, (PDF) Improving the rotary kilnelectric furnace process

Calcination

Calcination refers to thermal treatment of a solid chemical compound (eg mixed carbonate ores) whereby the compound is raised to high temperature without melting under restricted supply of ambient oxygen (ie gaseous O2 fraction of air), generally for the purpose of removing impurities or volatile substances and/or to incur thermal decomposition The root of the word calcination refers to its most prominent use, which is to remove carbon from The calciner rotary kiln, or indirect kiln, is a rotating drum inside an externallyheated furnace that can reach temperatures as high as 3000°F that must be tightly controlled to Calciner Rotary Kiln AirPro Fan & Blower Company
