By using variable speed drives (VSD) to control high efficiency motors in your cement manufacturing process, you can reduce energy consumption significantly compared to traditional fixed speed motors. VSDs also provide you an accurate control for your processes, and our PLCs help all your processes to work in coordination with each other. Our portfolio includes a wide range of low voltage ...
Together, the drives' variable speed capability and Advanced Cell Bypass technology allowed the mine to maximize throughput while maintaining motor efficiency. After installing the SINAMICS PERFECT HARMONY VFD on their ball mill appliions, the mine owners saw such improvement in their process — and profits! — that they went on to install the drive on three additional appliions as well.
Variable Speed Drive For Cement Mills. The variable speed motor drive system is more efficient than all other flow control methods including valves, turbines, hydraulic transmissions, dampers, etc. Energy cost savings becomes more pronounced in variabletorque ID fan and pump appliions, where the load's torque and power is directly ...
Many grinding mill owners choose a variable speed drive for their mill to cope with variations in ore hardness, plant throughput and other process considerations. Two important engineering decisions that owners must make before purchasing a variable speed drive system are the selection of the motor nominal design speed and the motor maximum speed. An inherent design characteristic is that ...
