Introduction of PLC automatic control system for Raymond mil

Raymond mill is very much used in non-mineral powder, because it has a great advantage in cost performance, which is a very good investment choice for many small and medium-sized enterprises. Redmond grinding group USES PLC automatic control system to greatly save control of labor cost.
In contrast to the large Raymond mill manufacturers, the number of small and medium sized mill units that use the coverage area is still lagging behind. Electrical control system basic choose knife control or button control, this control method there are a lot of shortcomings, first question: forced to control completely, electrical equipment disabled rate is high, it and mechanical equipment fault caused each other, vicious circle, especially the knife type, its fundamental circuits are do not have maintenance function, not requirements; The motor operating current of Raymond mill is not intuitive, and it is difficult to make the best adjustment with the pointer type current meter. The start-stop order of each motor is the operator's experience and manual performance, and the labor intensity is large. The wiring is more and more messy, the control cabinet is large, the special anti-dust function is poor, and the electric contact pollution is easy to cause many kinds of problems; The maintenance device USES ac contactor to complete "undervoltage maintenance, air switch and thermal relay to complete short circuit and overload maintenance, it is forced maintenance." It is difficult to manipulate the grinding mill with high application requirements, and it is difficult to reach the optimal operation. Therefore, it is urgent to solve the problem of improving the automatic control level of the progressive grinding mill with high and new skill and electromechanical integration and replacing backward electric control system.
Against the status quo of China's small and medium-sized Raymond mill group now, combined with today's high-tech skills, we began a traditional electric control method of small and medium-sized Raymond unit skills improvement discussion, in order to progress the automation level, complete the intelligent control. Because the small and medium abrasive units are used for urban and rural areas, the price of products is very sensitive. Therefore, it is designed to be efficient, useful, low cost, easy to operate, reliable and so on, so that it has outstanding function and price. This study concludes that the intelligent human machine system should be used to ensure the completion and the normal operation of the equipment.
