High Energy Centrifugal Disc - Batch & Semi Automated

$0.00

Surface Preparation features a complete line of High Energy Centrifugal Disc Finishers.

The rotating spinner (60 – 250 rpm) accelerates the mass of work pieces, media and compound to the wall of the stationary work bowl and pushes the mass upwards along the wall of the work bowl. With decreasing acceleration and increasing gravity, the mass slides back down to the spinner where it is again accelerated.

Features of high energy centrifugal disc machines:

  • Optimum dynamic geometry of spinner and work bowl
  • Infinite water level control
  • Automatic gap control (on some models) can be adjusted within a tolerance of 0.01 mm
  • Rinsing of gap prevents premature wear of spinner and work bowl
  • Anti-blocking system prevents "seizure" of the spinner
  • Additional protection of spinner and work bowl by temperature control in the gap area

Batch Machines
These are stand-alone machines for operation without an integrated loader, screening machine and media return system. The work bowl is pivoted either manually, electrically, or hydraulically on larger machines. By providing appropriate peripheral equipment such as loading and separation devices, a partial degree of automation is also possible.

Semi Automated Machines
These are pivoted centrifugal disc systems with an integrated screening machine and media hopper. When the centrifugal disc finishing process is complete, the system pivots by 135°, this transports the media and work-pieces onto the screening machine where they are separated and the media is classified. When the system pivots back into the processing position, the media slides back from the media hopper and automatically reloads into the work bowl.
