Rosser Head Debarkers

Rosser Head Debarkers

Southern Cross has been manufacturing Rosser Head Debarkers for many years 

The logs are rotated singularly in a cradle with driven rollers while a spinning cutter head passes over the log and moves along its length. 

The Rosser head debarker works similar to a lathe in the method it removes bark. Rosser head debarkers are primarily used in slower speed operations, in hardwood mills or on larger crooked logs.

Ring Debarkers

Ring Debarkers

Southern Cross egineering represents a World Leading Supplier of Ring Debarkers namely Nicholson Manufacturing of Canada. 

Nicholson have been developing debarkers for over 60 years and can boast the fastest debarkers in the world with debarking speed exceeding 150mpm. The design of their debarking ring and tool arms provides excellent debarking to the equal of any other on the market today.  Indeed others often require fitting two rings to achieve the same debarking performance.

The Debarkers that are currently under production start from a new low speed and simple debarker known as the R2; the A1 Model is a heavy duty debarker for rough and larger logs with a reasonable feed speeds.  You can have either the fabricated chain feed or the roll feed unit.  An example of the later was recently installed at the Timberlands, KPP site in Kaiangaroa where the application calls for both speed (up to 90mpm+); a lifting ring design and to have the ability to process tree stem length logs (up to 38m long) of quite rough quality on a 24 hour / 7 day a week basis.

The Slow to Medium speed debarker range is the A6 and there are many examples of this model in Australia and N Z. 

The A5 model which was developed some years ago is still available as the A5C for some ring sizes and offers excellent debarking at quite high speeds but at a discount to the latest and fastest model the A8.

The A8 is the Rolls Royce of Ring Debarkers and has no direct competitor for strength of design, speed of debarking, accessibility for maintenance, and reliability.  Although quite a new model there are now well over 100 machines of this model world-wide and we have supplied 3 into our market in the last few years.

Some photos of the debarkers we have supplied recently can be seen below:
