Process and system for preparing high-grade limestone powder by utilizing low-grade limestone
The invention belongs to the technical field of production of steelmaking lime from limestone, and particularly relates to a process and a system for preparing high-grade limestone powder from low-grade limestone, and the method for preparing the high-grade limestone powder from the low-grade limestone comprises the following steps: step 1, crushing the low-grade limestone; the particle size of the crushed limestone particles is 10-100 mm; 2, the limestone particles obtained in the step 1 pass through a component analyzer, the limestone particles meeting the set conditions of the component analyzer serve as coarse screening high-grade limestone to be homogenized and ground, and ground coarse screening high-grade limestone powder is obtained; and 3, sorting the coarse-screened high-grade limestone powder obtained in the step 2. The invention provides a process and a system for preparing high-grade limestone powder by using low-grade limestone, which can be used for producing steelmaking lime by calcining limestone which cannot meet the requirements originally.
本发明属于石灰石生产炼钢石灰技术领域，尤其涉及一种利用低品位石灰石制高品位石灰石粉的工艺及其系统，所述利用低品位石灰石制高品位石灰石粉的方法包括以下步骤：步骤一：对低品位石灰石进行破碎，破碎后的石灰石颗粒粒径为10‑100mm；步骤二：步骤一得到的石灰石颗粒通过成分分析仪，将满足成分分析仪设定条件的石灰石颗粒作为粗筛高品位石灰石进行均化和粉磨，得到粉磨后的粗筛高品位石灰石粉；步骤三：将步骤二得到的粗筛高品位石灰石粉进行分选。本发明提供一种可以利用原来不能满足前述要求的石灰石，可以通过煅烧来生产炼钢石灰的利用低品位石灰石制高品位石灰石粉的工艺及其系统。
