AI Technical Summary
In existing grinding mills, the low transmission efficiency of V-belts and reducer teeth leads to high energy loss, severe equipment vibration, and high maintenance costs.
The system employs a suspended permanent magnet motor, which is directly driven by a second motor. The fixing components are secured to the grinding roller hanger, scraper holder, and grinding ring by bolts or welding. The motor is located near the center line of the frame, reducing transmission losses and improving equipment stability.
It improves transmission efficiency, reduces energy consumption and vibration, increases equipment stability, increases speed and output, and reduces costs for enterprises and customers.
