CMD has developed the range of ROLLEREX reducers to drive vertical mills using rollers. These ROLLEREX reducers are designed to withstand all efforts stemming from the milling operation while driving rotation of the vertical mill. In this context, CMD has decided to combine performance and reliability in the design of the ROLLEREX range .

Features
Input
Spiral bevel gear train, cut on a Klingelnberg machine
Output
Planetary gear train with sun and satellites made of forged steel type 18CrNiMo7-6 with teething hardened tempered and ground.
Axial efforts are supported by the means of several independent, oscillating thrust pads
Lubrification
The independent central unit is made up of a high pressure circuit and low pressure circuit.
