The invention belongs to the technical field of limestone preparation, and particularly relates to a limestone pulverizing and calcining rotary kiln which enables flue gas to be in full contact with limestone powder in the process of calcining the limestone powder into the quicklime powder, so that the calcining effect is improved. In the cooling process of quicklime powder, cooling water located in the inner side of the kiln body in the cooling pipe can enter the part, located in the outer side of the kiln body, of the cooling pipe in time for heat dissipation, and the cooling effect is improved; an annular sealing groove is formed in the end face, making contact with a feeding pipeline, of the kiln body, and a high-pressure gas ring is formed in the sealing groove, so that the gas pressure in the sealing groove and the gas pressure in the kiln body tend to be balanced, and high-pressure smoke leakage is avoided.
本发明属于石灰石制备技术领域，具体涉及一种石灰石制粉煅烧回转窑，本发明的石灰石制粉煅烧回转窑在将石灰石粉进行煅烧成为生石灰粉的过程中，使得烟气与石灰石粉得到充分接触，提高了煅烧的效果；本发明对生石灰粉进行冷却过程中，能够使冷却管内位于窑身内侧的冷却水及时进入冷却管位于窑身外侧的部分散热，提高了冷却效果；本发明在窑身和进料管道接触的端面上开设有环形的密封槽，并使得密封槽内形成高压气环，从而使得密封槽内气压与窑身内气压趋于平衡，避免了高压烟气泄漏。
