For well-designed Rotary Kiln devices, whether from the tires, roller Rotary kiln and other scattered parts support basic conditions for both high-speed operation of the entire device.About its structure and the association will this. Rotary kiln tire usually consists of a single ring composed of steel castings, machined smooth cylindrical surface, Rotary kiln shell loosely connected by arranging a variety of chairs.Because the shell close to the tire must meet, but also allows thermal movement. Riding tire steel rolls machined to a smooth cylindrical surface, and set a distance of about half the diameter of the Rotary kiln.Drum must be support from the Rotary kiln, and allows almost no rotational friction as possible.
