Functions and damage types of rotary kiln tyre

The role of the rotary kiln tyre (also known as the rolling ring) is to transfer the weight of the cylinder (including refractory bricks, internal devices and materials, etc.) to the support roller, and to enable the cylinder to rotate smoothly on the support roller, so the kiln tyre must have sufficient strength and durability. At the same time, the rotary kiln tyre is a part that reinforces
