The kiln cylinder of Rotary Kiln is the rotation component be heated which is welded by the high quality composure steel plate. The cylinder is on the bearing device by the tyre bearing of 2-7 gear sliding bearing. Among one or more gear of the bearing device, there is machinery or hydraulic pressure catch wheel to control the axial movement of the Rotary Kiln cylinder; the rotary kiln transmission device makes the cylinder rotate according to the required speed by the gear ring in the middle; due to the need of rotary kiln installation and rotary kiln maintenance, the bigger kiln is equipped with the auxiliary drive which makes the barrel rotate with a very low speed; to protect the cold air from entering and the smoke dust spilling out, the reliable kiln end and kiln head sealing device is installed in the rotary kiln cylinder feeding end and discharging end.Cement kiln refers to the revolving clinker calcining kiln, which is a crucial equipment when producing high quality cement in the cement factory. It is composed of cylinder, supporting roller and foundation devices, Race Ring and Flange, Gear ring and Flange, Shifting Wheel Device, Movable kiln head, Sealed device of kiln tail, Burner Barrel and etc. This will be usually situated on an east/west axis to prevent eddy currents.Upper limits on diameter are set by the tendency of the shell to deform under its own weight to an oval cross section, with consequent flexure during rotation. The Rotary Kiln"s length is not necessarily limited, but it becomes difficult to cope with changes in length on heating and cooling (typically around 0.1 to 0.5% of the length) if the kiln body is very long.It is aslo widely in building materials, metallurgy, chemical industry, construction, environmental protection industries. We can design the whole cement production line, including making the clinker from crushing, powder concentration, calcinating of raw material and milling by Cement Mill and packing.
