The invention belongs to the field of cement, and particularly relates to a cement grinding process. The cement grinding process comprises the following steps that calcined cement clinker is put intothe upstream end, located at one end in the axial direction, of screw crushing equipment with the axis being horizontally arranged, and large cement clinker blocks are crushed into cement clinker particles with the large particle size through the screw crushing equipment; and the cement clinker particles are moved to the downstream end, located at the other end in the axial direction, of the screwcrushing equipment. According to the cement grinding process, cement clinkers with different particle sizes can be sorted, crushed and ground step by step; and the large cement clinker blocks can beefficiently and uniformly crushed by adopting screw crushing, and the problems of heavy bounce and non-uniform crushing effect of grinding roller crushing are avoided.
本发明属于水泥领域，特别涉及一种水泥磨粉工艺。一种水泥磨粉工艺，包括以下步骤：将煅烧后的水泥熟料投入到轴线水平设置的螺杆破碎设备位于轴向一端的上游端中，通过螺杆破碎设备将大块的水泥熟料破碎成大粒径的水泥熟料颗粒，并使水泥熟料颗粒运动至螺杆破碎设备位于轴向另一端的下游端。本发明能够针对不同颗粒大小的水泥熟料，进行分选分步破碎磨粉；且采用螺杆破碎能够对大块的水泥熟料进行高效且均匀地破碎，且避免了磨辊破碎存在跳动大，破碎效果不均匀的问题。
