Potash ore lime rotary kiln

r. Technical advantages of lime rotary kiln Lime rotary kiln's reliable combined scale sealing at both ends of the rotary kiln makes the air leakage coefficient less than %. In addition, composite refractory materials are used to reduce radiant heat loss. The lime rotary kiln uses a filled, removable The circular or square vertical cooler with zone ventilation makes the temperature of the lime coming out of the cooler + the ambient temperature, which facilitates transportation and storage, and can preheat the secondary air entering the kiln to above, reducing moving parts and special materials.
r. Lime rotary kiln’s requirements for the layout of low points r Lime rotary kiln cannot be installed anywhere and it has very high requirements for the layout of low points. r The center height of the rotary kiln should be determined according to the type and layout of the clinker cooler. r The layout of the foundation piers of the rotary kiln should comply with the following regulations: r) The installation dimensions of the rotary kiln should be based on the cold kiln r) The horizontal distance between the foundation piers should be determined based on the size after thermal expansion r) Calculation of the axial thermal expansion of the kiln barrel The center of the belt with a stop wheel located near the transmission device should be used as the reference point to expand toward both ends. r) The slope of the foundation surface should be equal to the slope of the kiln barrel. The foundation hole should be perpendicular to the foundation surface. r When there are more than two rotary kilns, the determination of the center distance of the two kilns should comply with the following principles: r) Meet the layout requirements of the kiln head and kiln tail equipment r) Be convenient for equipment operation and maintenance r) Combined with the reasonable location of the central control room .
