The Revolution Of The Ball Mill Drive Technology

The revolution of the ball mill drive technology

The ball mill is essential for cement, mining, metallurgy, power generation, ceramics and other industries. The most common y series motor or slip speed motor to drag the ball mill, there is difficulty in starting, operating efficiency is low, grinding a long time, the unit power consumption of higher defects. Memec, Shandong Electric Co., Ltd. developed Switched Reluctance energy-saving motor speed control system can replace the existing ordinary motor or slip speed motor to reduce costs and improve the effectiveness of the effect.

Commonly used in order to solve the start of the ball mushroom normal motor star - delta start way at the same time increasing the motor capacity, while the normal operation of the motor load is less than the rated load of the motor, resulting in the phenomenon of the large horse-drawn trolley, waste of energy. Using star - delta starter the way motor carried load is very difficult when the motor starts, often after a few start, so that the ball mill to the formation of a certain coherence to start. Starting current is very large, serious harm on the grid impact, sometimes occur burned contactors, circuit, motor and other phenomena. And mechanical parts of the impact, reducing the useful life of equipment.Bring a certain threat to the normal production and cause undue economic losses. With slip speed motor to solve the problem of the difficult start, but the slip speed and low efficiency, resulting in energy waste, and difficult to maintain equipment maintenance volume to the user problem, not a good solution to the practical problems of the ball mushroom.

Switched Reluctance variable speed motors is a new generation of energy efficient variable speed motors, only a small starting current, starting torque, soft-start features with speed adjustable function. Can reach its maximum starting torque of 2.8 times the rated torque to solve the problem of ball mushroom starting torque, the motor start current small impact on the grid, and extend the life of the contact devices such as. The motor has a wide speed range and up to 80% system efficiency in a wide speed range and significant energy saving effect. We have developed srd10 type Switched Reluctance Motor Controller has a simple programmable logic controller (plc), according to the degree of processing of raw materials according to different time periods to set the motor speed, the device running at its best state, increasing labor productivity, shorten the grinding time, reduce electricity costs, and improve economic efficiency. Switched reluctance motor system is simple and works reliably and has a protective function, so the occurrence of stall motor will not burn, improve the life of the motor:

Similar to the ball mill works and working conditions of mining machinery there are rotary kiln, drying tube and other production equipment in the industrial and mining and chemical companies in the production mill the same problem can not be a good solution, if the switch Reluctance Motor This new technology will fundamentally solve the above problems, to bring a revolution of the industrial technology to rewrite the history of industrial kilns and machinery, electrical drives.

With its high quality products such as China impact crusher, Sand washing plant, Rock crushing plant, Ore beneficiation, Dryer machine, Henan Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
