Dr. Paul mill start saving device Smart Saver, is my German company to introduce sophisticated mature intelligent power control technology, combined with the world's most high-frequency technology features, and domestic application characteristics, the new concept of self-developed series of high performance. Under the premise of improving the stability increases simple PLC, PID practical section, flexible input and output terminals, online parameters setting, self-identification signal transmission failures, power outages and downtime parameter storage, electrical energy control, traverse control, RS485 control, Fieldbus control and a series of practical operation of advanced control functions. For equipment manufacturers and end customers with high integration of integrated solutions for reducing system acquisition and operating costs, improve system reliability is of great help. 1 ,? Overview mill cement industry, ceramic industry, mining and mineral processing industries indispensable equipment, but also the three biggest share of power industry equipment, the entire production of electricity consumption accounts for about 40% -50% . The protection of the quality of production, under the premise of production is not affected, how to reduce the mill's power consumption has been a problem in these three sectors investor concern. Saving transformation of a ball mill, to reduce the production cost of these three sectors, increase profitability of great significance. ???? 2 ,? works in the cement industry, ceramic industry, mining and mineral processing industry, ore crusher preliminary first by crushing, fine crushing to a reasonable degree fed into the mill after the first warehouse in the warehouse has ladder liner or corrugated liner, there are different specifications of steel balls appointed chest, when the cylinder rotates, centrifugal force due to the ball a certain height and then was brought down, things cooking line pounding and grinding compartment in. In this way, large pieces of material to complete the first step of kibble in the first barn. Completion of coarse material by single-compartment plate into the second position, in this warehouse lined with flat lining, which also has a lot of balls, where the material will be further grinding, this step is termed class finely ground. After these two steps of the job, the original chunk of material became largely been grinding powder, powdered materials finally discharged through the discharge grate plate to complete the grinding operation. Centrifugation speed control system existing grinding speed and grinding balls is constant, grinding time is usually set based on experience, but also requires a large starting torque when the ball starts, a great inrush current. Our professionals through a lot of experiments and research, on the running track and force balls decomposition, with inverter technology on the entire work process mill track sampling, Dr. Paul developed a special energy-saving ball mill control cabinet. Dr. Paul mill saving control cabinet with frequency of way, by adjusting the speed of the motor, the output torque and speed of the ball mill process requirements of the motor to achieve the best fit, so that not only improves the efficiency of the mill, a ball mill optimization the production process, but also greatly reduces the mill's power. 3 ,? Features l excellent soft-start, the ball mill greatly reduce the starting current, avoiding tripping under control with the original phenomenon;? L increase mill efficiency, optimize production processes;? L to grind all the time? speed segments can be set according to the requirements of the production process, easy to operate; l saving rate:? According to the requirements of different production processes, saving rate of 10% -20%.
