INDUSTRY Centrifuge Bonitron > Industries > Centrifuge

 

Centrifuges are used extensively in industry to seperate particles or materials from a solution and the non-usable material is discharged. The electric motor of a centrifuge is commonly controlled by a variable frequency drive (VFD), allowing for precise control of the centrifuge.

Batch Processing

  • Particle Separation or mixing is accomplished by high velocity spin.
  • Regenerative Energy is Created due to Rapid Decel between batches
  • Drive DC Bus Over-voltage is created by the rotational inertia during decel of the centrifuge
  • Can take long periods to coast to stop creating long periods of nonproductively between batches

Batch centrifuges require stopping when the process is complete. Bonitron Dynamic Braking and Line Regeneration would allow for braking the centrifuge, increasing throughput of the centrifuge by increasing uptime.

Common Bus Batch Process Centrifuges

  • Single motor and VFD for a single centrifuge
  • Several batch process VFDs could be common bussed
  • Energy created from a stopping centrifuge can be used to power/start other centrifuges
  • VFDs can be common bussed to use one regen or brake for Multiple Centrifuges
  • Common bus and regenerative energy solution must be sized to cover all the VFDs on the common bus

Continuous Process Centrifuge

  • Process that has material feed to centrifuge continuously
  • Several Process Stages During Cycle
  • Regenerative Energy Created by Rapid Deceleration During the Stages and overhauling drives in the process
 

 

  • 100% Regenerative
  • The drum spins faster than the augur
  • Augur regenerates
  • Generally 50-100Hp VFDs are used

Transistor & Resistor vs. Line Regeneration

Braking units prevent overvoltage faults on drives. A dynamic brake or "chopper" uses transistors that turn on before overvoltage situations occur, allowing excess energy to be dissipated to connected resistors. A regenerative brake channels the energy back onto the utility grid where it can be used by other equipment within the facility.
