Jeffrey Rader - Model Chip-Sizer™ -Rechipper

At their first look, people assume that they are looking at a typical wood hog. While the operating principal is similar to a wood hog, the Chip-Sizer™ rechipper incorporates several special features and components.

The Jeffrey Rader designed Chip-Sizer™ hammer allows the unit to operate at speeds much slower than hammermills, and also offers a “soft-touch” to the chips to keep from creating pins and fines. This along with other patented components permits the Chip-Sizer™ rechipper to reduce oversized chips at unheard of efficiencies.

• Large infeed opening ensures that plugging is eliminated in the Chip-sizer rechipper.
• No knives to sharpen or damage keeps maintenance costs low.
• Low capital cost provides a rapid ROI.
• High recovery rates increase profits.
• Ships complete with motor, drive assembly and base for quick installation.
• Metal trap minimizes damage from tramp metal.

Tramp Metal
The inherent configuration and heavy duty nature of hammermills means the the Chip-sizer has no knives to sharpen or be destroyed by tramp metal. The Chip-sizer feed and discharge openings are large enough to prevent plugging.
 
Easy Maintenance
Routine maintenance consists of greasing the bearings and checking the tension on the drive belt per the guidelines in the maintenance manual. It is also recommended that you check the wear on the chipping hammers and screen bars 2-3 times annually.

High Value Results in Processing Hardwood and Softwood with the Jeffrey Rader Chip-Sizer™ 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 86-95%. This value is so high that many producers are eliminating screening after the Chip-sizer rechipper and feeding directly to the "accepts" belt.

A system using the Chip-Sizer™ rechipper therefore does not usually need a screen to recirculate overs. It also does not require an air handling system, since oversize chips are dropped vertically off a belt into the machine and discharged onto another belt. Experience has shown that surge loads of up to double the machine’s rated capacity can be accommodated without plugging.
 
Fast Payback
High recovery rates and reduced maintenance costs have generated significant improvements in profits for companies operating these machines. Furthermore, the lower capital costs of Jeffrey Rader Chip-sizer rechipper systems yield very attractive returns on investment.

ROI analyses have been done for many installations, and most payback times have been less than one year. It is in the order of 3-6 months for new plants or those that do not have a conventional rechipper. Even plants with rechippers have converted to Chip-sizer rechipper and have returned their investments typically within the year.
 
Industry Acceptance
The Jeffrey Rader Chip-sizer rechipper is the first of its kind in the chip market. Today, with more than 100 rechippers in the field, this is the sizer that has proven it gives the highest recovery rates of "cookable" chips of any rechipper. Acceptance of the Chip-sizer rechipper has been rapid and widespread, with numerous chip producers and multi-national pulp & paper companies installing machines.
