一 立窑煅烧工艺简介立窑小水泥占我国水泥总产量的70%左右,但是煅烧操作主要靠手工。工艺过程由图1可以看出:生料粉配一定量的粉煤输送到成球盘,加水滚成小料球,料球均匀撒布在窑的表面,不断下降,经预热、烧成、冷却到最底部卸出。风则由下往上冷却熟料的同时被预 A shaft kiln calcination process Brief introduction Shaft kiln cement accounts for about 70% of China’s total output of cement, but mainly by manual calcination operation. Process can be seen from Figure 1: raw meal with a certain amount of pulverized coal delivered to the ball plate, add water roll into small balls, the ball evenly spread on the surface of the kiln, falling, after preheating, firing, Cooling to the bottom of the unloading. Wind from the bottom up while cooling clinker was pre-
