Cement rotary kiln maintenance mainly includes playing kiln coating, demolition of brick, cleaning and masonry.In order to make the time of stopping the kiln as short as possible,we usually play  kiln coating and demolition of brick after the rotary kiln for sale is cooled for 10-12 hours,when the kiln temperature will still be above 90 degreee,so both playing kiln skin and demolition of brick are operating at high temperatures high dust environment.

According to common sense,we generally do not want equipment  driven by diesel engine uses in conditions of high temperature and high dust, because the diesel engine is not high temperature resistance,and high dust can paste dead air filter and radiator, resulting in frequent failure and impacting the work of hitting a brick.Influenced by the kiln door size,the bridge generally is relatively narrow, whem the machine is from the bridge through the grate cooler,it is better that worker is separated with car. The accidents that driving the small excavator through the bridge caused that people and vehicles fall into the grate cooler  have been reported at home and abroad.

The demolition of brick and playing kiln skin is broken by a hydraulic breaker, the inevitable situation that slag jump and splash and kiln leather slump occurs,in order to prevent accidents of personal safety, it is desirable to stay away from work surface and not to fix sitting on the machine so that ther can not escape. In order to enter the smaller kiln door, and you do not want kiln cover to do additional transformation,it is required that width and height of playing brick is smaller,and the weight light.At the same time impact power of the hydraulic crushing hammer need as large as possibile to quickly finish the job,and it need to play kiln castable.Dismantle Brick need to be able to quickly hit the kiln coating demolition of brick, but it can not damage the cylinder. Which requires hydraulic hammer impact energy and frequency kiln adjustable stepless .

Design of the machine must be taken into account reliable operation in the case of high temperature and high dust, the failure rate is lower,and using cost is low.Therefore, the international common practice is that no longer the diesel driven construction machinery used in the rotary kiln production line within playing kiln coating and demolition of brick.
