Advantage And Disadvantage Of Ultrafine Vertical Mill

បានប្រកាសនៅ Business នៅMay 24 2021 at 08:43 AM

This driving mode is a common driving mode of large-scale ultrafine vertical mill, which is generally used on the long-distance large-scale ultrafine vertical mill with a length of more than 800m.

Advantages: simple structure, load starting, protection of motor overload, less maintenance workload, when the motor is empty and driven by more than one motor, it can be started separately and delayed to reduce the impact of ultrafine vertical mill on the power grid when starting, with high reliability, good soft starting performance, controllable starting performance, that is, controllable starting time, controllable starting speed curve, and low price.

Disadvantages: when the hydraulic coupling starts, because the curve of oil quantity change and speed change in the working chamber of the hydraulic coupling is nonlinear and has the property of postponing, the controllability dynamic response is slow, the closed-loop control is difficult, and sometimes oil leakage occurs. It is not suitable for the transportation of ultrafine vertical mill and ultrafine vertical mill with speed regulating function.
