Auspine Limited, located in Mt Gambier, South Australia, has ordered the latest debarking technology from Wilson Engineering. The new Nicholson A8 high-speed debarker and flare reducer will be first in Australia, and Auspine's choice for future debarking capacity over the next 20 years.

Wilson Engineering and Auspine signed contracts in May.  Stiff competition came from VK and other suppliers, but the new breed debarker, and the confidence in Wilson Engineering to complete the project on time and satisfy the client’s needs, won the contract.

The project involves removing the existing debarker, bark waste conveyors, butt reducer and existing debarker shed. Installation involves placement of the new A8 and support steel, the step feeder will be relocated, new log deck installed, new waste conveyors and a new debarker, MCC and hydraulics building.  Electrical and mechanical installation contracts are also with Wilson Engineering. The installation will take place over the Christmas shut down period in a time frame of two weeks. 

A8 Debarker Information

The A8 was introduced in 2002 and has sold 79 units over the world. 
 
The debarker is a fixed ring, fully automatic, high-speed, high-production machine. It is made from 3" steel plate and is of very rugged construction for the most demanding applications. It is designed for virtually all debarking situations on logs as short as 7 feet ,and speeds to 550 feet per minute depending on the size of the debarker. The air seal ring design gives the operator complete remote control of the debarking knives while the log is being debarked. He can open or close the knife arms with a lever switch or vary the barking pressure with a programmable display unit to suit the log conditions.

The flare reducer ring consists of a rotating ring similar to a debarking ring, to the face of which 5 knife assemblies are attached. Each knife assembly is mounted on a carrier that can be adjusted very quickly and easily to allow the flare ring to reduce logs of varying diameter. The knife assemblies are the key knife type with two knives - one knife removes the flare and the other trues and smooths the log surface.
