Debarking / Debarker / Drum Debarker
Area of Application:
The Drum Debarker, type PDD was developed for the economical and gentle debarking of logs. The Drum Debarker is not only used in the OSB-industry but also in all industries where thoroughly debarked round logs are required. The modularly designed system was constructed for the debarking of logs of medium and larger diameters at high capacity in order to meet the high demands of the OSB industry.

Method of Operation:
Depending on material conditions and customers demands, the drum debarker can be fed via gravity feed chute for short logs or by means of a horizontal conveyor. The main component of the machine, the debarking drum, is driven by electric motors. Special tire sets transmit a rotational force to the drum. The interior of the drum is equipped with a series of logs that are used for log transport and are made of wear-resistant material. The retention time of the wood in the drum determines the degree of debarking and can be adjusted by the setting of the discharge gate and by the rotation of the drum. The friction of the logs between each other and the drum removes the bark.

Technical data of the series PDD:
Drum diameter: 3.0 - 5.0 m
Drum length 12 - 32 m
Log length 1 - 8 m
Throughput rate: 40 - 350 m³ (fm) atro/h
