微型计算机控制物料配比与产量,不仅要求解决自动计量问题,而且要解决自动控制问题,因此它是一个较复杂的闭环系统,由计量、数据采集、数据处理和反馈控制等环节组成.图1是水泥磨的系统框图.每个水泥磨系统由石膏(G)、混合材(M)和熟料(c)三台胶带输送机构成.连续称重和测速的电信号经运算、处理、并进行比较,再实时调节带速,从而达到控制水泥的配比与产量的要求.
Microcomputer control of material ratio and output, not only to solve the problem of automatic measurement, but also to solve the problem of automatic control, so it is a more complex closed-loop system, by the measurement, data acquisition, data processing and feedback control and other links. Is a system block diagram of a cement mill Each cement mill system consists of three belt conveyors, gypsum (G), mixed material (M) and clinker (c) .Electrical signals for continuous weighing and speed measurement are processed and processed For comparison, and then adjust the speed with real-time, so as to achieve the control of cement ratio and yield requirements.
