Direct Fired Rotary Kiln | Internal Heating Rotary Kiln
In a word, a direct-fired rotary kiln is used for sintering and roasting ores, concentrates, and intermediate products. Using direct combustion of coal, flue gas, coal gas, or natural gas as the heat source, the materials are oxidized and roasted in the rotary kiln, and chemical changes occur to produce materials that meet the requirements.

Rotary Kiln Incinerators & Process Development Services
A rotary kiln incinerator breaks down or decomposes material into simple compounds via complete combustion, converting wastes to an ash residue and thereby significantly reducing waste volume. To achieve this, a direct-fired, refractory-lined rotary kiln uses a co-current (parallel) configuration, in combination with an oxygen-rich environment.

Direct-Fired vs. Indirect-Fired Rotary Kilns
An indirect kiln also offers superior temperature control along the length of the kiln. In an indirect-fired rotary kiln, the heat is introduced to the outside of the drum shell via gas burners or electric heaters. In essence, the rotary kiln is rotating inside of a stationary housing. This avoids any direct contact between the heat source and ...
