Replacement and renovation of hydraulic system for Shuangma cement raw material vertical mill:

1. Achieved three seconds of detachment from the material layer, with minimal vibration during roller lifting and falling

2. It has achieved functions such as one three pressure, two four pressure rollers, integral pressure roller, integral lifting roller, and does not affect the use of a damaged pump. It also has functions such as differential lifting roller and lower chamber backup pressure buffering, with complete functions and strong applicability.

3. Horizontal and vertical vibration values: 0.6-0.9nm/s

4. After the installation of the hydraulic system, control cabinet, and accumulator valve group, they were debugged and put into production normally in just two days, which is quite remarkable!
