The invention relates to the field of cement, in particular to a cement production process. The waste raw materials can be used for preparing the cement. A cement production process comprises the following steps: (A) taking waste raw materials containing calcium oxide, silicon dioxide, aluminum oxide and ferric oxide by weight, pre-crushing, and then putting the waste raw materials into a raw material mill for grinding to form a mixture; (B) putting the mixture into a raw material bin, introducing air into the raw material bin, increasing the pressure in the raw material bin, and stirring to form a blended raw material; (C) adding the blended raw material into a suspension type preheater for preheating, and introducing the preheated blended raw material into a rotary kiln for heating to form clinker; (D) cooling the clinker in a cooling machine; and (E) adding the cooled clinker into a crusher for pre-crushing, adding gypsum into the crushed clinker, simultaneously adding the gypsum and the pre-crushed clinker into grinding equipment, grinding into powder, and stirring to form the cement.
本发明涉及水泥领域，更具体的说是一种水泥生产工艺。本发明可以使用废旧原料制备水泥。一种水泥生产工艺，包括以下步骤：(A)按重量取带有氧化钙、二氧化硅、氧化铝和氧化铁废旧原料进行预破碎，然后将废旧原料放置在原料磨中进行粉磨形成混合料；(B)将混合料放入原料仓内，向原料仓内通入空气，使得原料仓内升压后并进行搅拌，形成调和生料；(C)将调和生料加入悬浮式预热器中预热，预热后将调和生料通入回转窑中加热后形成熟料；(D)将熟料通入冷却机中冷却；(E)将冷却后的熟料加入破碎机中预破碎，在破碎后的熟料内加入石膏，将石膏和预破碎后的熟料同时加入粉磨设备磨成粉状，并搅拌后形成水泥。
