Under the mandate given topography determines the plant process layout, draw the plant process layout and the limestone pre-blending bed process layout. In this design, the entire production line use one-stop arrangement, flow smooth process, save transportation equipment; the whole process from raw materials to the cement leave factory all use homogenization measures, guarantee the quality of cement; the main equipment selection from the raw mill to cement mill adopt vertical mill, they have high grinding efficiency, low unit power consumption, large grinding space, high drying ability; pulverized coal pre-blending using circular pre-blending bed, they have smaller floor area, contrast with the rectangle pre-blending bed they can avoided the telos effect, they use the lambdoidal windrow ( end face take material ), solve the transition zone better. Keywords: limestone; circular pre-blending bed ; telos effect ; homogenizing effect 目录 TOC \o 1-3 \h \u HYPERLINK \l _Toc28457 1 引言 l _Toc20430 1.1 新型干法水泥技术的生产特点 l _Toc17848 1.2 新型干法水泥的生产发展 l _Toc3803 2 参数的确定 l _Toc7036 2.2 熟料热耗的确定 l _Toc17263 2.3 熟料标号的确定 l _Toc4165 2.4 石膏加入量、混合材加入量的确定 l _Toc4390 2.4.1 石膏加入量的确定 l _Toc30726 2.4.2 混合材加入量的确定 l _Toc26572 3 物料平衡计算 l _Toc18554 3.1 配料计算 l _Toc3
