IEM ROTARY DEBARKER VS. RING DEBARKER

The IEM Ring Debarker Versus Rotary Debarker Page Compares Manufacturing Technologies, And Maintenance Breakdown.

Assumptions - Ring Debarker Technology

  • It cannot debark eucalyptus

  • The average stem length is 6 m

  • The diameter range is between 70 mm to 400 mm

  • The average diameter is 125 mm

  • It runs at 6000 hours per annum operation

  • The solid wood production target range is 300 m3 per hour

IEM Rotary Debarker
Maintenance Breakdown

  • Maintenance cost: $0.08 / m3

  • 300 m3 x 6000 hours x $0.08 / m3 =

  • $144,000.00 maintenance costs per annum

  • Over $1,000,000.00 maintenance saving a year!

Ring Debarker
Maintenance Breakdown

  • Maintenance cost: $0.75 / m3

  • 300 m3 x 6000 hours x $0.75 / m3 =

  • $1,350,000.00 maintenance costs per annum

  • Disc cutters for stringy bark

IEM Side Dischange Rotary Debarker Performance Breakdown

  • It is a multiple stem process

  • Log diameter has no impact on production

  • No minimum length

  • No minimum or maximum diameter

  • 1% white wood losses guaranteed

  • 3000 hours between maintenance
    requirements

  • Wood is processed 0.4 to 0.8 kw hr per m3

  • 82 to 84 decibels

  • It will increase fiber yield

  • Maintenance costs $0.08/m3 solid wood

  • Debarker holds 22 to 24 m3 solid wood per charge

  • Equipment has a 20+ year life

  • We replace ring debarkers every year

Ring Debarker
Performance Breakdown

  • Single stem process

  • Counter rotating ring for stringy bark

  • It cannot accept logs shorter than 1.8m

  • White wood loss higher than rotary

  • It has issues with stringy bark build up around tooling

  • Log diameter has a direct influence on production

  • 400 fpm:

75mm diameter stems - max production per hour - 30 m3
125mm diameter stems - max production per hour - 85 m3
150mm diameter stems - max production per hour - 125 m3

  • To achieve target production of 125 mm, the needed average diameter diet is 4 ring debarkers
