Unlike directly fired calciners, indirect rotary calciners are heated from the outside of an enclosed chamber. This gives them the ability to process materials that are fine or dusty, susceptible to contamination or combustion, sensitive to oxidation, or thermally sensitive.
Mar 16, 2017· Indirect fired heaters can actually help some wintertime processes, like the curing of concrete, along. Fuel savings Direct fired heaters may be more fuel efficient overall, but since indirect fired heaters do not have the fresh air requirements of direct fired heaters, they can save fuel when used in recirculation mode or to warm nearby spaces.
Our gas fired calciners and our electric kilns can process powders up to 2700 °F. We can dry small sample batches or tackle large scale production processing of up to 1,500 lbs of powder an hour. Our calciners are used for both drying and altering the composition if .
Indirect Fired Thermal Soil Remediation Plants are used when the project requires the gas flow within the dryer (super heated steam and hydrocabrons) to be separate from the dryer's heat source. There can be two common reasons: Specific contaminates ( chlorinated compounds) are required to be out of direct contact with the dryer flame.

The preheated spodumene then enters the kiln where the temperature gradually increases to the conversion temperature. Once converted, the hot beta spodumene then discharges into a rotary cooler where the temperature is reduced via a combination of direct and indirect water cooling. It is then discharged and sent to the next step in the process.
