Construction Process of Rotary Kiln Lining
Large rotary kilns are mostly lined with refractory bricks . The main methods for lining construction are as follows. Template Method The template method is mostly suitable for circumferential continuous joint masonry. See the diagram below: Figure: Schematic diagram of rotary kiln lining construction using the template method (circumferential continuous joint lining) The lining is constructed from the lowest point of the cross-section in two circumferential directions. When the height exceeds the kiln's centerline, a mold is set up, and the lining is closed from both directions towards the highest point of the cross-section, with support provided as construction progresses until the locking is complete. The mold shown in the diagram is a relatively simple one, entirely manual, resulting in low construction efficiency. To improve efficiency, many companies have adopted pneumatic support rings. The equipment has two rows of pneumatic support devices, significantly improving c...
