When should determine the Rotary kiln unsealed after blending rate then gradually return to normal operation in accordance with the actual situation of the required value.In a few days before determining seal the Rotary kiln, the blending process should be a lower rate, ensuring non-stick Rotary kilns and nodulation. To achieve cooling temperatures below the material to make sticky Rotary kiln temperature, the rate of the ingredients until the mixture reduces installed after the closure of the Rotary kiln insulation.By increasing the blending ratio of the mixture into the Rotary kiln sealing Rotary kiln.How much they increased blending Rate seal the Rotary kiln for a few days (up to 1 to 2 months), and may vary within the range of 1% to 5%, less the number of days the Rotary kiln sealing, blending ratio corresponding to an increase less, sealed Rotary kiln few more days, blending ratio corresponding to increase more.
