Technical advantages of gray rotary kiln Lime rotary kiln has reliable combined scale seals at both ends of the rotary kiln, making the air leakage coefficient less than %. In addition, composite refractory materials are used to reduce radiant heat loss. Lime rotary kiln uses filled and zoned ventilation. The circular or square vertical cooler makes the temperature of the lime coming out of the cooler + ambient temperature, which is convenient for transportation and storage. It can also preheat the secondary air entering the kiln to above, reducing moving parts and special materials.
, ash rotary kiln’s requirements for the layout of low points
, Ash rotary kiln cannot be installed anywhere, and it has very high requirements for the layout of low points.
, the center height of the rotary kiln should be determined according to the type and layout of the clinker cooler.
, The layout of the foundation piers of the rotary kiln should comply with the following regulations
, The installation dimensions of the rotary kiln should always be based on the cold kiln
, The horizontal distance between the foundation piers should be based on the size after thermal expansion Determine
, the calculation of the axial thermal expansion of the kiln barrel should be based on the center of the wheel belt with a stop wheel located near the transmission device, and expand toward both ends
, the slope of the foundation surface should be consistent with the kiln barrel The body slopes should be equal and the foundation holes should be perpendicular to the foundation surface.
, When there are more than two rotary kilns, the determination of the center distance of the two kilns should comply with the following principles
, to meet the layout requirements of the kiln head and kiln tail equipment
and to facilitate equipment operation and Maintenance
, combined with the reasonable location of the central control room.
