New discover of fuzzy control in ball mill
Fuzzy Control (FC) algorithm is the 1970s developed a new control algorithm, by its very nature is a kind of nonlinear control, it does not jaw crusher need to know the mathematical model of the controlled object, and better than the conventional control system stability, more robust and a good anti-noise performance, and easy manual operation experience in the combination can be effective in achieving control of nonlinear systems.
Ball tube mill is one of the most important auxiliary equipments in domestic power plants nowadays. It’s safe and economic operation is the key of the first magnitude. However, most mills are still in the state of manual control. The reason is that mill governing system has multi-inputs and multi-outputs, strong coupling, tardiness, inertia and complicated dynamic character. It has some difficulty for the control of this system. Using three traditional PID controllers isolated, the satisfactory purpose is impossible and it can’t run in the best situation.
Intellective-control theory representative the EFC technology and also puts forward new question for control of ball mill. This paper combined control system of ball mill and the reality of overage grind, discussed the application of EFC in the automatic control of ball mill. Based on the ball mill overage grind and study actuality, this paper stress analyzed the dynamic characteristic of ball mill. And this paper put forward square delivery correspond EFC system. This paper presented collectivity scheme, software, hardware and realization scheme. EFC effectively resolved the entrance press of ball tube mill and temperature strong coupling of its export. This system can better control function of ball mill. This system has the superior characteristic of stabilization, credibility, save, tight structure simple operation. ore beneficiation:http://www.hx-crusher.com/ore_beneficiation.html

Fuzzy Control using fuzzy language rules, will run the experience summarized, stored in a computer numerical computation, fuzzy control, first by adjusting the amount of coal, heat, recirculation damper, so that the coal pulverizer mill load, the outlet temperature and entrance negative pressure control in the given range, the upcoming coal Cone Crushermill to adjust to the best working conditions; Secondly, in the case of negative pressure, temperature normal, the adjustment to the amount of coal to coal pulverizer memory the amount of coal to achieve contribute to the maximum and consumption per unit minimum. Usage (dry or wet):
Ball mill is the key equipment for grinding after the crushing process, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other grind-able materials.
