Commonly known as the rotary kiln, the rotary calcining kiln is also called the rotary dryer, belonging to construction equipment. Depending on the materials, the rotary kiln falls into three types: the metallurgy kiln, the lime kiln and the cement kiln.
The structure of rotary kiln
1.1 barrel
Rotary kiln barrel is rolled by the different thickness steel plate, cylinder body with refractory material, cylinder suit has several belting leather outside, cylinder with a certain slope, located on the wheel and corresponding belting leather;
Roller cone out between axial bending. Return roller down cylinder deformation and leave largest belting leather center, the smaller the distance, the greater the cylinder radial deformation.
1.2 belting leather
Belting leather is a solid steel ring set on the barrel, support rotary kiln (including brick kiln and material) of all gravity;
The weight of the belting leather from 20 tons (3.6 m) in diameter to 100 tons (5.6 m) in diameter.
Belting leather near the wall thickness increase, the purpose is to reduce the pressure of the roller and the deformation.
1.3 roller
Roller through the bearings in the kiln, on the basis of the bearing installed on the concrete pier;
Note: roller and belting leather surface clean, smooth on the surface of the roller and belting leather, lubrication on the surface of the roller, the temperature of the shaft, wheel balance;
Wheel (its diameter is commonly belting leather 1/4, wide bandwidth than the 50-100 mm, it’s because when considering thermal kiln and kiln belting leather position is different, at the same time that the entire surface roller is mobile belting leather wear uniform, otherwise it will leave grooves, not work properly.
1.4 hydraulic gear wheel
Hydraulic gear wheel revolves around the longitudinal axis movement of the wheel installed in the preheater belting leather near the kiln head side of the plane;
Role: in a timely manner is pointed out that the running...
