Regarding the motor, we need that you ask ABB for the delivered kW with the following motor frequencies:
Dryer without wesp and without Sand separators (original situation):
Motor speed for 4 pole motor: 36,5 Hz
Delivered Motor Power at the indicated speed: 500 kW
Dryer with wesp and with Sand separators (future situation):
Please see the details for the 500kW motor and the booster fan
Let me know if that is sufficient enough
Hopefully we can use the 4 pole motor , it will help us on spare parts inventory a lot
Please confirm back if you need some more details
