水泥生产有十几道工序,其中生料喂料(或称配料或配制)和烧成是关键工序。其工序执行的好坏,对水泥的质量和产量产生最为重大的影响。因此,在水泥生产中,无不对该两项工序倍加留意,细心操作。 所谓生料喂料,就是将四种原料——石灰石、黄泥、煤粉、铁粉,按照化验室分析得出的最佳配比(例如:石∶泥∶煤∶铁=68∶19∶11∶2),凭借自动机构或手动机构进行连续或断续配料并送入球磨搅拌机混合、粉碎。过去,喂料工序几乎毫无例外地采用图1所示的圆盘喂料机构:四个圆盘由同一电动机和齿轮箱带动。四种原料的料库置于圆盘正上方,
There are dozens of cement production processes, including raw materials feeding (or ingredients or preparation) and firing is the key process. The performance of its processes is good or bad, the quality of cement and yield have the most significant impact. Therefore, in the production of cement, all of these two processes are twice as careful and careful operation. The so-called raw material feeding, is the four raw materials - limestone, yellow mud, pulverized coal, iron powder, according to laboratory analysis of the best ratio (for example: stone: mud: coal: iron = 68:19: 11:2), with automatic or manual agencies for continuous or intermittent ingredients and into the ball mill mixer, crushed. In the past, the feeding process used almost without exception the disk feeding mechanism shown in Fig. 1: the four disks were driven by the same motor and gearbox. Four kinds of raw materials placed in the magazine just above the disk,
