Four Major Prats of Rotary Kiln

Rotary Kiln refers towards the revolving calcinating kiln (namely revolving kiln), that is mainly applied for calcinations of clinker, refractory material, bauxite, aluminum oxide, hematite, limestone, dolomite and other components.

The rotary kiln is manufactured of four essential parts ,it contains shell, refractory lining, assistance tyres and rollers, drive gear and inner heat exchaLead ore mining equipment indiangers.

Kiln Shell:This really is manufactured from rolled mild steel plate, ordinarily amongst 15 and 30 mm thick, welded to kind a cylinder which can be as much as 230 m in length and as much as 6 m in diameter. Upper limits on diameter are set from the tendency from the shell to deform beneath its very own fat to an oval cross area, with consequent flexure all through rotation. Length isn't always restricted, nevertheless it turns into hard to cope with modifications in length on heating and cooling (usually all around 0.one to 0.5% in the length), should the kiln is extremely prolonged.

Refractory Lining:The goal on the refractory lining is always to insulate the steel shell from the superior temperatures inside the kiln, and to defend it from the corrosive properties of your method substance. It could include refractory bricks or cast refractory concrete, or may well be absent in zones in the kiln which might be under close to 250C. The refractory picked depends upon the temperature within the kiln as well as chemical nature from the substance currently being processed. In some processes, including cement, the refractory existence is prolonged by maintaining a coating of your processed material for the refractory surface. The thickness from the lining is usually while in the assortment 80 to 300 mm. A common refractory might be capable of retaining a temperature drop of 1000 or even more involving its sizzling and cold faces. The shell temperature wants to become maintained below all over 350 so that you can shield the steel from...
