Rollerex : Reducers for vertical mill drives

 
 
Presentation
 

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 .

Advantages
 
  • Sizing adapted to most currently used vertical mills
  • Extremely compact
  • Extremely low noise level
  • Capacity to withstand the axial efforts and vibrations stemming from the mill with great safety
  • A very safe and efficient hydraulic and electrical system
  • Lubrication units adapted to each reducer of the range
  • A design and production quality recognised throughout the mechanical world
 
 
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.
