Rotary kiln is a combustion equipment, can use the solid, liquid and gas fuel, the cement plant is given priority to with the use of solid fuel in our country, because of the need to spray combustion, so the solid fuel made into powder.Pulverized coal pulverized coal into coal after drying, after warehouse, with the blower from the kiln head injection into the stove.Combustion air is made up of two parts, part in advance and conveying pulverized coal mixing and the function of the air, called 'air', generally accounts for 15% of the total air - 15%, most of the air through the cooling machine clinker cooling, at the same time itself be preheated to a certain temperature, into the furnace, this part is called 'secondary air'. However, do you know the belting Leather of rotary kiln?

The based information on belting leather of rotary kiln is as follows:

Belting leather is a solid circle rims, installed on the cylinder, the full weight of the rotary kiln, passed to roller belting leather.Belting leather with the cylinder on the wheel rolling, its itself also increase cylinder rigid role. Belting leather is in cast iron or steel, forging belting leather its cross section is solid structure, good quality service life long, but the heat dissipation is poor, poor rigidity, manufacture process is complex, cross section size larger belting leather, generally using the casting, the cross section has a solid rectangle and hollow box type two kinds

Belting leather on the cylinder of rotary kiln (http://www.sell-crusher.com/pro/p29.html) installation method has two kinds, the general is fixed, the belting leather rivet directly by plate on the cylinder.This kind of installation method limits the free expansion of cylinder, the thermal stress of shell and belting leather is bigger, so rarely used, the other is a loop on the cylinder, riveting or welding plate on the cylinder, belting leather and leave appropriate gap between plate, general for 3-6 mm, it is controllable heating stress and can make full use of the rigidity of belting leather, to reinforce the effect to the cylinder, therefore, is more commonly used methods.

With the continuous increase of the rotary kiln size, to perfect rigid demand is higher and higher, because of the mechanical manufacturing technology constantly improve current foreign some use belting leather with integration of cylinder structure, its structure characteristics, belting leather as support both parts, but also a part of the cylinder.The fixed shell and at the same time with the method of welding connection, instead of a suit, in order to improve the cylinder's rigidity.
