Chip-Sizers by Jeffrey Rader Brand

Our Chip-Sizer™ is the first true no-knife rechipper, made to reduce oversized wood chips with a minimum of fines produced and low maintenance costs.

Features

With over 200 Chip-Sizers in the field today, this is the sizer that has proven it gives the highest recovery rates of “cookable” chips of any rechipper. Results from numerous installations processing hardwood and softwood show that the percentage of oversize chips processed to acceptable chips is typically in the range of 85-95%. This value is so high that many producers are eliminating screening after the Chip-Sizer and feeding directly to the “accepts” belt.

Our patented Chip-Sizer design incorporates several special features and components:

  • Chip-Sizer’s hammers allow for much slower operation speeds than hammermills.
  • A “soft touch” from the hammers minimizes pins and fines.
  • Large feed opening eliminates infeed plugging.
  • Access door permits fast, easy servicing.
  • Chipping hammers reduce downtime — there are no knives that require sharpening.
  • Metal trap minimizes damage from tramp metal.
  • Replaceable wear-resistant liners extend service life.

Cost-Effective Operation:

  • Low capital cost provides a rapid ROI.
  • High recovery rates, typically 85-95%, increase profits.
  • Efficient screen bar design produces a high percentage of accepts. Generally, the finished product goes directly to the accepts belt, thus eliminating a cyclone and increasing screen capacity.
  • High-performance, double-row spherical bearings accommodate extra loads and produce smoother operation.
  • Operational adaptability.

Easy Maintenance:

  • Routine maintenance consists of greasing the bearings and checking drive belt tension
Technical Data

General Information

  • Double row, spherical roller bearings used on all models
  • Replaceable breaker plate liners and side liners on all models
  • All liners are drilled and tapped to reduce the possibility of liners falling into the unit
  • All models feature a metal trap for tramp metal collection
  • Hammer and Screen Grate configuration selected based on application needs
  • Effective screen area is approximately 180 degrees
  • Standard lubrication is Grease; however optional oil circulating systems are available
