A type of a modern dry process cement rotary kiln

Modern dry process cement kiln, and are based on round with live sets at the barrel, and allow proper clearance for installation-specific tire not directly mounted on the cement kiln Festival, mounted on the plate on , so that the cement kiln formed between the cylinder and the wheel with natural ventilation channels. Strengthen the heat, on the other hand reduces the round with the heat conduction from the cement kiln body, making the round with the outer edge of the temperature difference is smaller.

Modern dry process lime kiln, and are based on round with live sets at the barrel, and allow proper clearance for installation-specific tire not directly mounted on the lime kiln Festival, mounted on the plate on , so that the lime kiln formed between the cylinder and the wheel with natural ventilation channels. Strengthen the heat, on the other hand reduces the round with the heat conduction from the lime kiln body, making the round with the outer edge of the temperature difference is smaller. When the lime kiln thermal changes in the system, its temperature change is not large, thus reducing the tire temperature stress.

A well-engineered rotary kiln,when the power is cut off, will swing pendulum-like many times before coming to rest. The mass of a typical 6 x 60 m rotary kiln, including refractories and feed, is around 1100 tonnes, and would be carried on three tyres and sets of rotary kiln rollers, spaced along the length of the rotary kiln.The longest rotary kiln may have 8 sets of rollers, while very short rotary kiln may have only two.rotary kiln usually rotate at 0.5 to 2 rpm, but sometimes as fast as 5 rpm. The rotary kiln of most modern cement plants are running at 4 to 5 rpm. The bearings of the rotary kiln rollers must be capable of withstanding the large static and live loads involved, and must be carefully protected from the heat of the rotary kiln and the ingress of dust. In addition to support rotary kiln rollers, there are usually upper and lower ‘retaining rollers’ bearing against the side of tyres, that prevent the rotary kiln from slipping off the support rollers.
