Rotary kiln in the production process, through continuous high temperature operation, will continue to shorten the life of refractories. Sometimes falling bricks, kiln refractories for a certain period or be replaced, in order to reduce and eliminate unnecessary risk, you need to pay attention to some matters: 1, see the fire from the platform through the kiln hood to the kiln, to take from a suitable springboard; 2, passed in the kiln, first check the kiln and put the loose skin hanging heavy objects removed; 4, in the loose refractory kiln work below the skin as no other method can be replaced, you had better use protection network; 5, any person working in the kiln, the kiln should not start to ensure practical ways, for example by locking the kiln drive lock; 6, handling kiln bricks and peeling skin, there must be correct posture and safe pace; 7, when the material is being pulled out from the kiln or kiln feed it, not in the kiln hood springboard for the following work; 8, when workers in the kiln, do not test the cooling machine operation; 9, when workers in the kiln back end or the chain band, do not run the exhaust fan. These nine o'clock through long practice lessons learned from, a lot of places to re-re-assemble directly on the fire bricks or material to draw upon.
