Cement rotary kiln plays an important role in cement production process,it is used for the calcination of cement clinker.Cement rotary kiln is mainly composed of kiln body,rotating device,riding wheel,sealing device and other parts. PRM can produce rotary kiln components including girth gear, rotary kiln tyre, support roller, thrust roller and etc.
The rotary kiln tyre is mainly used to transmit the weight of the cylinder to the supporting roller, so that the cylinder can rotate smoothly on the supporting roller. However, the rotary kiln tyres will be damaged in different ways during use. Common tyre damages include premature wear, insufficient rigidity of the tires, cracks on the radial section of …
A support roller is a cylindrical component that allows the kiln to work in a rotary condition. Properly maintain rollers are clean, free from oil, dust, shiny surface, correctly aligned …
