important operation tips for cement vertical mill

2021-3-17 · When the grinding pressure is low, the thickness of the layer increases, the current of the main motor increases, the pressure difference within the mill increases, and the vibration of the mill increases. When the grinding pressure is high, the thickness of the layer decreases and the current of the main motor increases. The vibration speed of the mill increases and the component damage is accelerated. So maintaining a proper grinding pressure is a critical operation. Mill
