Kiln tyre is also called riding ring, is one of the main parts of rotary kiln equipment. The kiln tyre can pass all drum gravity (including the gravity of refractory brick, internal device and material) to riding wheel, and make the drum smoothly rotating on the wheel. Therefore the kiln tyre should have enough strength and durability. At the same time, kiln tyre strengthens drum radial stiffness so it should have enough rigidity.
