A moving ring is a sealing ring that rotates with the axis, while a static ring is a sealing ring that does not rotate with the axis. In the mechanical seal, the moving ring is installed on the shaft and rotates with the shaft, while the static ring is fixed on the inside or outside of the pressure lid, forming a mechanical seal. This classification is based on their function and position in the coal mill, with moving rings being rotated to reduce wear, while static rings are fixed to provide a stable seal effect
In addition, the dynamic ring structure of the coal mill also includes other components, such as elastic parts, support rod, gear, gear ring, etc., which work together to ensure the normal operation and sealing effect of the coal mill 2. For example, wear-resistant parts can be set in the gap formed between the moving ring and the static ring to avoid the gap between the moving ring and the static ring increasing too fast and ensure the output of the coal mill
In conclusion, the main difference between the moving rings and the static rings of the coal mill lies in their position and function: the moving rings rotate with the axis to reduce wear, while the static rings are fixed to provide the sealing effect.
