introduction：1. Frequency conversion scheme is proposed There is a centrifugal dryer in the lithium slag recovery unit of catalyst workshop，It works like a dryer in a household washing machine，Specially responsible for the dehydration and drying of lithium carbonate products containing more water。The dryer was originally equipped4Polar asynchronous machine5.5kW，Spin dry drum RPM approx1200r/min，But the drying effect is not ideal。After use to increase the speed（1600r/min）And increase the motor power（7.5kW）method，Although the dehydrating effect is better，The motor often trips due to overload。 Measured by inspection，The motor is after starting，Its running current up to30
