figure rotary kiln

A rotary kiln, as shown diagramatically in Figure 2, is a long refractory-lined inclined tube slowly rotated to ensure the steady flow of solid material from the feeder at the higher end to the collector at the lower.A burner at the lower end produces hot gases which pass in countercurrent flow to the moving solids

Oct 24, 2012 1.1 Rotary kilns. Rotary kilns [] are long cylindrical industrial furnaces that for their operation are slightly tilted as shown in Figure 1.They are used in a wide range of material processing industries. The material to be processed is fed into the upper end of the cylinder, leaving a

The rotary kiln gasifier is used in several applications, varying from industrial waste to cement production and the reactor accomplishes two objectives simultaneously: (1) moving solids into and out of a high temperature reaction zone and (2) assuring thorough mixing of the solids during reaction. The kiln is typically comprised of a steel cylindrical shell lined with abrasion-resistant refractory – to prevent overheating of the metal – and is

Rotary kilns (Figure 1) are used for a range of mineral processing operations. Kilns range in size from 2–6 m in diameter and can be 50–225 m long with an operating mass of up to 3000 t. Two of the most common applications are for cement production and sponge iron production. Hatch has developed a proprietary one-dimensional kiln model to
