Base Frame Assembly

Base Frame Assembly

The static and dynamic load of machine is high so to sustain that there is use of base frame (22). The rotating assembly is covered with guard (16).

  • Wide-ranging performance.
  • Performance criteria.
  • Five crucial factors determine the performance of decanter centrifuges:
    • Centrifugal force required for sedimentation of the solids.
    • Clarification area necessary to “capture” the solids.
    • Differential speed required to transport the solids out of the decanter.
    • Hydrodynamic design, which determines the exact parameters for the turbulence.
    • Design of the conveyor and beach sections, which are important for efficient solids transportation.

Characteristic features of centrifuges which meet hygienic requirements are:

  • All welds are ground to meet specific sanitary finish standards (optional).
  • All product wetted parts are provided with a surface finish in accordance with specified surface roughness values.
  • Spray nozzles are provided for the centrifuge housing and for the interior of the scroll body.
  • The centrate impeller is adjustable to facilitate the flushing of the bowl.
  • Frequency-controlled drives for CIP-cleaning at low speed.
  • Electro-polished scroll, housing and bowl surfaces (optional).

Most sizes and models of these centrifuges are available in a variety of rotor and housing seal designs for the following operating conditions:

  • Atmospheric
  • Vapor-Tight
  • Gas-Tight

These centrifuges can also be adapted for operating in closed-loop systems.

Atmospheric Centrifuge

They are used for applications where there is no harm from products or vapors released to the environment.

  1. Vapor-Tight Version

    Decanter centrifuges are the right choice in cases where substances emitted from the process could pollute the environment of if contact of the product with ambient air is undesirable. Additional seals on rotor shafts and housings provide the necessary seal. Emissions can be eliminated when purge gas/air is applied to seals or when the centrifuge housing is vented.

  2. Gas-Tight Centrifuge

    Allow for safe operation with toxic, corrosive or flammable media by applying inert purge gas to rotor seals and by inerting the process chamber and centrifuge housing. Slight positive or negative pressures can be maintained in the process area by regulating the purge gas supply. Special sealing elements minimize the seal gas consumption.
