Smarter debarking

NEW DESIGN FEATURES HIGH SPEED DEBARKING, EASY MAINTENANCE

USNR / Söderhamn Eriksson introduces another step forward in advanced debarking with the release of Cambio 800D. New features and practical design elements make this our best debarker yet!

• Higher speed

• Easier to service, maintain

• Reduced noise, bark spray

• Reduced operating cost

• Higher redundancy

• Longer life

Specifications:

• Max. feedspeed: 130m/min (426 fpm)

• Max. log dia.: 800mm (32”)

• Min. log dia.: 90mm (3.5”)

• Weight including cover: 12,600 kg (28,000 lbs.)

• Feedwork drives: 4kw x 6 arms

• Rotor drive: 75kw 6pol

• Separate oil lube system for rotor lubrication, incl. filter and monitoring

• Electrical actuators to open/close the covers

Jonas Ljung, designer (profiled on page 24), explains the concept, “We know how costly it is for a mill when a machine is down, so we wanted to build in further redundancy to our Cambio design, to ensure our debarker could keep running even if a drive unit should fail. This way the mill can keep running and change it out during the next scheduled maintenance.”

The drive units are attached into the arm with 4 screws, so changing the drive is much less time consuming. The new design accommodates the same size of logs and a slightly higher speed than the traditional Cambio 800 (130m/min vs. 110).

We know how costly it is for a mill when a machine is down, so we wanted to build in further redundancy to our Cambio design, to ensure our debarker could keep running even if a drive unit should fail.

Features

With its separately driven feed rolls and new, patented suspension system, the Cambio 800D debarker is designed for high speeds and for all timber sizes.

Cambio 800D has separate electric motors for each feed roll. This reduces the number of moving parts which results in lower costs for maintenance and spare parts. The drive units are designed as individual modules and can easily be replaced.

With this new design, we have made the covers tighter to minimize noise and bark spray, and to provide a better environment around the machine. The covers can be opened to a wide angle which increases access and speeds up the maintenance work.

A new patented hydraulic suspension system – HYDA – controls the clamping force. The new suspension system also puts less stress on the frame and extends the lifespan of the machine.

The reduced number of moving parts and the absence of bevel gears makes the Cambio 800D well suited for modern high speed sawmills.

The Cambio 800D has built-in redundancy. The debarker remains functional even if one of the drive units should fail. This all sums up to reduced downtime and lower maintenance costs.

The Cambio 800D is available as a stand-alone debarker unit. This design has been installed in two mills to date, one in Norway and the other in south Sweden.
