Grinding process automatic control system

The main task of the automatic control of the grinding process is to make the grinding and grading production process work under stable or optimal conditions, fully exert and improve the grinding and grading efficiency, so that the useful minerals and gangues can achieve sufficient monomer dissociation to ensure overflow. Product quality in order to achieve higher economic benefits.
In the closed-circuit grinding process consisting of a grinding machine and a spiral classifier, the process from feeding to grading products has a large lag time. Grinding machine lining wear changes the effective volume and effective power of the mill. The wear of the steel ball is out of balance with the amount of steel ball and the diameter of the steel ball. The wear of the spiral classifier spiral will change the characteristics of the controlled object and control. The requirements of the system, that is, the controlled object has time-varying characteristics. The controlled object also has nonlinear characteristics, such as the nonlinear relationship between grinding efficiency and filling rate. The grinding process is restricted by various parameters. Some parameters are uncontrollable and unmeasurable, such as the hardness of the ore. There is no effective process detection method, and the grinding machine and the cyclone closed circuit process have similar situations. Therefore, the corresponding control strategy should be designed for this object feature. The examples presented here focus on the control strategy. The selection of the automatic control device should meet the design requirements of the control system and the development of the control device itself and the possibility of its selection.
Grinding control system according to the actual requirements of the beneficiation plant, the control system is also different, which can be controlled mainly by the amount and the control amount is divided into the basic parameters of a single control loop, such as to control the amount of ore, to the water (grinding Concentration) control and overflow concentration or particle size control, etc. Considering the interaction between the loops, the multi-parameter integrated control system of the grinding process can be formed on the basis of these loops, the tuning control of the second-stage grinding and the adaptive optimization control.

Fever Clinic Emergency Room

The emergency room should have an independent consultation area with separate entrances and exits and clear emergency signs, so that patients can clearly find the triage area for consultation. The emergency department should be open for consultation 24 hours a day for easy management. While ensuring medical functionality, it is also important to consider the psychological needs of patients and medical staff, and strive to create a convenient, efficient, comfortable, and warm treatment environment.
