Direct-heating furnace – Taeda(Taida) Group Dryer …

The direct-heating furnace, is mainly made of three parts, such as furnace hearth, setting pocket and mixing room. The temperature is very high in the space between the setting pocket and the mixing room, to make the volatile combustible air burn sufficiently. The fuel is filled in by the furnace door, which forms burning layers on the grate.

How does a Rotary Kiln Work?

Rotary kilns can be either direct-fired, or indirect-fired (calciners). Direct-fired kilns use direct contact between the material and the process gas to cause the reaction, whereas indirect kilns rely on the heat emanating from the shell of the drum, which is externally heated to temperature. In the case of a direct-fired kiln, a refractory ...

Rotary Kilns vs. Rotary Dryers: What's the Difference?

Rotary dryers are used for drawing moisture out of a material. As such, they typically operate at temperatures between 800º – 1400ºF. In contrast, rotary kilns are used to cause a chemical reaction or phase change, requiring them to operate at much higher temperatures, typically between 1000º – 3000ºF. Some moisture reduction may occur ...

Rotary Dryer Design & Working Principle

Rotary driers have thermal efficiencies of from 50 to 75 per cent on ores. This must be taken into account when using the above table, which is figured at 100 per cent. The drier shell is rotated separately from the stationary kiln section. To achieve the rotation a BULL GEAR is attached around the shell section.
