Big Bowl, large Extruder rate, PLC control is the development trend of centrifuge production, especially for oil & gas drilling fluids decanter centrifuge. VFD and Hydraulic are 2 kinds of drive method, both of them have their own advantages, but VFD control decanter centrifuge is much more popular and easy maintenance at present. Here I will introduce and compare some world famous VFD big bowl decanter centrifuge.
