How to Maintenance the Cement Rotary Kiln?

Cement rotary kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates. Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually define the capacity of the cement plant. As the main energy-consuming and greenhouse-gas–emitting stage of cement manufacture, improvement of kiln efficiency has been the central concern of cement manufacturing technology.but what are the requirements for fault repair of cement rotary kiln?

1. Brick removing machine can quickly play rotating drying kiln skin and split brick, without any damage to cylinder, the impact energy and frequency of kiln which calls for the stepless adjustable of frequency furnace and ballistic work of hydraulic hammer, in order to enter smaller kiln door without additional transformation of kiln hood ,it requires the machine width and height to be small, light weight. At the same time, hydraulic breaking hammer impact power is big to finish quickly, but also to hit kiln head castable.

2. Influenced by the clinker rotary kiln door size, generally gap bridge is quite narrow, machine by the bridge through the grate cooler,it is best that people and vehicles are not together. Generally equipment driven by diesel engine is used in under the premise of high temperature and dust, because the diesel engine is not resistant to high temperature, and high dust will paste air cleaner and radiator dead, thus resulting in frequent breakdown and affecting hitting brick.

3. The maintenance of circumgyrate cement kiln mainly includes hitting kiln skin,brick disassembly, cleaning and brick masonry. In order to minimize the stop time of kiln, playing kiln skin and removing brick usually starts after the rotary kiln cooling for 10-12 hours, the kiln temperature is still above 90 ℃, thus playing...
