※Soft Start: After the ball mill uses frequency conversion speed regulation, the starting current can be3-5times smaller than before. ※Energy - savingEffect:The energy - saving effect of the ball mill frequency conversion speed regulationenergy - saving system is generally about 5%- 15%. ※Speed ControlE: The frequency converter PLCruns automatically,and the grinding time, heating time, andautomatic shutdown functions can be conveniently set through PLC, making the operation more intelligentand user - friendly. ※Service Life: By using the automatic voltage regulation function of the frequency converter, the motor efficiency is kept at the highest level. Because the impact at startup is eliminated, the service life of mechanicalparts such as shafts, gears, and belts is extended, and maintenance costs are reduced. ※Protection: The system has complete protection functions such as phase loss, short circuit, over - voltage,and over- current. At the same time, it can be equipped with functions such as power grid/energy -savingswitching, effectively ensuring the stable operation of the equipment.
