It is also equipped with limestone, gypsum crushing, conveying and adding equipment. This production system is referred to as the "two grinding and one burning" system, that is, raw material mill, cement mill and rotary kiln burning. The entire production process is centrally controlled by an advanced distributed computer control system, which has the characteristics of high automation, stable process and strong reliability.The cement production process includes the stages of raw material mining and transportation, raw meal preparation, pulverized coal preparation, clinker burning and cement grinding. The main production process is that after limestone and auxiliary raw materials (glue, silica) are crushed, they are matched with treated industrial waste in appropriate proportions, crushed by a vertical raw material mill to prepare raw meal, and then enter the raw material homogenizing pile for homogenization treatment. It enters the rotary kiln through the 5-stage sealed external calciner (RSP), burns the clinker in a high temperature state, and enters the clinker storage: it is then crushed by a cement mill equipped with a compilation press, and finally forms various types of cement products. .

Therefore, the calorific value and mass ratio (that is, the ratio of coal with calorific value per unit of waste to the total mass of material input in co-processing) is used as the basis for data allocation of input and output. For details, see the formula αp = W'p/(W'p + Wc + Wr). In the formula, αp is the distribution ratio of input and output of waste in the co-processing system; W'p is the coal quality (t) corresponding to the calorific value ratio of 1 ton of waste; Wc is the coal that needs to be added to clinker production for 1 ton of waste. Mass (t); Wr is the mass of raw meal (t) that needs to be added to the waste in clinker production for 1t. 工业废弃物可替代部分煤，因此，采用热值和质量比例（即单位废弃物对应热值的煤与协同处置中物质投入总质量的比例）作为输入输出的数据分配依据，具体见式αp = W'p/（W'p + Wc + Wr）。式中，αp为废弃物在协同处置系统输入输出的分配比例；W'p为1t废弃物按热值比对应的煤质量（t）；Wc为 1t废弃物在熟料生产中需要添加的煤质量（t）； Wr为 1t 废弃物在熟料生产中需要添加的生料质量（t）。 None 无 None 无 侯星宇, 张芸, 戚昱, 蒋慧, 张琳, & 曲殿利.
