Rotary kiln equipment double kiln lining advantages

The main usage of rotary kiln is used to calcine the material. At present, manufacturers have made some improvements to the rotary kiln, designed double kiln lining, then we have a look at the double kiln lining rotary kiln has the advantage.

1. Lower weight impact: Thanks toinsulation materials with lower bulk density, the double-lining design has alower total weight than the single-lining design. In this particular case, themass as a whole is reduced by 3.5%. The lighter weight will ease the ovaldeformation of the rotary kiln during use and will allow the gear and bearingto withstand less gravity. The lighter weight also affects the mechanicalstructure, such as thrust rollers, which means that less force is needed toprovide the required thrust for the roller.

2. The impact of the lower shell temperature:Due to the significant reduction of the shell temperature, the furnace shelland liner to better match. Compared with the lining design of single-layerlining, the rotary kiln with the above-mentioned recommended technicalindicators has a lower coefficient of linear expansion and the formulacalculates the linear thermal expansion with a value of 5.3 cm. This also meansthat the kiln will be subject to less thermal expansion stress, while thekiln's thermal expansion stress will have a significant impact on the servicelife of the kiln.

3. When the refractory needs overhaul, thestandard procedure for measuring the temperature of the steel shell is verynecessary. Rotary kiln, in the back of the working layer refractories installeddouble insulation structure insulation brick, to maintain better corrosionresistance. This is because the insulating material has a higher temperaturegradient during use. The lower energy loss in the kiln not only reduces energyconsumption but also provides better furnace temperature control in harshclimatic conditions. For example, under heavy rain conditions, the insulationprevents excessive cooling of the kiln.
