Modular Centrifugal Cleaner System

This unique and very useful system permits the analysis of centrifugal cleaning operations under realistic conditions but requires only a small amount of fiber (4-6 OD pounds.)

Cleaners are mounted above a 200-gallon (750-liter) tank from which they are fed and into which accepts and rejects are discharged. Multiple trial conditions may be used for a single batch of pulp.cleaner1

A high-speed, high-head centrifugal pump permits the development of the head and flow levels required for typical cleaners.

Fluid-filled, large-faced pressure gauges permit accurate measurement and control of pressure drop.

The following cleaners are available and may be run isolated or in series:

  • Beloit Posiflow
  • Beloit Uniflow
  • Celleco low-density
  • Noss forward canister
  • Noss reverse canister

Customer-supplied cleaner bodies are easily installed in the system.

A variety of nozzle types and inserts are available for each cleaner.

Shinhama Laboratory Kneader

Useful for ink dispersion, fiber surface modification, and strength enhancement.

This device features twin eccentric shafts which provide an intense rubbing action to pulp. Intensity is varied both by the number of passes and by an adjustable restrictor pin on the discharge.
