Limestone calcining process
The invention relates to the technical field of limestone calcination, and particularly discloses a limestone calcination process which comprises a crushing procedure, a material screening procedure, a preheating procedure and a calcination procedure, a preheater in the preheating procedure comprises a first preheating area and a second preheating area, and coarse materials and fine materials are screened out through the crushing procedure and the material screening procedure; coarse materials are input into a first preheating area and a second preheating area from the top of the preheater to be preheated, and enter a calcination procedure after preheating; and the fine material is input into the second preheating area from the side part of the preheater and enters a calcining process after being preheated. According to the invention, the preheating effect on coarse particles is improved; fine particles are fully utilized, the preheating effect on the fine particles is improved, the fine particles can be decomposed more completely after entering the rotary kiln, the quality of calcium oxide is further improved, the energy loss is reduced on the whole, the utilization rate of raw materials and resources and the overall production efficiency are improved, and the production cost is greatly saved.
本发明涉及石灰石煅烧技术领域，具体公开了一种石灰石煅烧工艺，包括有破碎工序、筛料工序、预热工序和煅烧工序，预热工序的预热器包括有第一预热区和第二预热区，通过破碎工序和筛料工序筛选出粗料和细料，粗料从预热器顶部输入第一预热区和第二预热区进行预热，预热后进入煅烧工序；细料从预热器侧部输入第二预热区，预热后进入煅烧工序。本发明提高了对粗料颗粒的预热效果；将细料颗粒充分利用起来，提高对细料颗粒的预热效果，使其在进入回转窑后能更完全的分解，进一步提高氧化钙的质量，并在整体上降低了能源损耗，提高了原料、资源的利用率和整体生产效率，大大节约了生产成本。
