Cement grinding intelligent control system and method

Abstract

The invention discloses intelligent control system and method for cement grinding. The intelligent control system for the cement grinding comprises a CPU, and a PLC control system which communicates with the CPU. The intelligent control system for the cement grinding is characterized by further comprising a granularity online analyzing instrument for monitoring the granularity of the cement and outputting a monitoring value on real time; the CPU controls a parameter setting module for setting initial working parameters of a cement grinding production device and recording as an initial target value, and an adaptive parameter adjusting module for adding or subtracting the initial target value according to the preset program to obtain a new target value and using the new target value as the adjusted initial target value; the PLC control system is used for analyzing and comparing the monitoring value and the initial target value and feeding back the comparing result to the CPU; the CPU selects one of the parameter setting module and the adaptive parameter adjusting model according to the comparing result to be used as the parameter for controlling output. According to the system, the control aims at keeping the optimal grinding condition to achieve quality and stable output and quality and high yield of cement grinding.

Description

technical field [0001] The invention relates to an intelligent control system and method for cement grinding. Background technique [0002] Cement grinding is the most important process of cement manufacturing. It is to transform clinker, gypsum, admixture and other non-hydraulic bulk materials into hydraulic powder materials. Its main function is to mix cement clinker and retarding Grinding agent, performance adjustment materials, etc. to a suitable particle size (indicated by fineness), in order to increase its hydration area, accelerate the hydration rate, and satisfy the cement paste coagulation. hardening requirements. [0003] At present, the microcomputer batching system adopted by my country's cement plants realizes the control of the proportion of raw materials in various channels, so that the chemical composition in the production process can meet the requirements of qualification, but in the production control, it mainly depends on the central control operator to...

[0003] At present, the microcomputer batching system adopted by my country's cement plants realizes the control of the proportion of raw materials in various channels, so that the chemical composition in the production process can meet the requirements of qualification, but in the production control, it mainly depends on the central control operator to adjust the production equipment Due to the uneven technical level of the central control operators, different operating ideas, different adjustment ranges, inaccurate adjustments, etc., there are often problems of over-adjustment or always a little bit, or in the condition of qualified quality It is difficult to maximize the output, or the output is maximized but the quality cannot meet the requirements
