Drive Types – Electric vs. Hydraulics


Electric Drives Generally, electric shredders require less space, are easier to operate and maintain, and are more energy efficient than their hydraulic counterparts. They also tend to be less expensive. Electric shredders are appropriate and sufficiently powered for processing many materials.

Hydraulic Drives — Hydraulic drives are often better for more heavy duty processing. They are also better for processing materials that experience frequent overloads from batch feeding. Hydraulic drives also offer better shockload protection from non-shreddables and work well with an Auto-Chop feature, allowing more precise particle size control.

Cumberland Shredder configured with an electric drive typeWhen would I need a hydraulic shredder? A hydraulically powered shredder might be more appropriate if you have any of the following factors in your processing environment:

  • Materials are batch fed.
  • Feed includes unsorted or unknown materials.
  • Materials are exceptionally difficult to shred.
  • Process requires tighter particle size control.
  • System needs to meter shredded material to downstream equipment.
  • System will require frequent starts and stops.
  • Shredder will require reduced voltage start (soft start).
