Mini Rolling Mill (Reducing and Sizing Mill)

Overhead Mini Rolling Mill Description:

1. The frame is a flat and vertical overhead cantilever, a centralized drive

2. High flexibility and speed ratio can be selected according to rolling specifications. The gear ratio is two gears.

3. High degree of automation

4. High rolling accuracy and more standardized dimension
