The Conveyors for debarker are used to transport logs to and from the debarker. There are two types of conveyor.
The conveyor in front of the debarker:
The conveyor is designed as a belt conveyor with a belt supported by roller idlers or as a longitudinal chain conveyor with a transport chain with lugs which moves on hardox slides. The frame is massive made of sectional steel and burnts, which supports the long operational life of the conveyor. The belt width is calculated according to the diameter of the logs. The type and rigidity of the belt or of the chain is calculated according to the transporting load capacity and the speed of the conveyor. The speed of the conveyor depends on the speed of a debarker and can be regulated by the frequency converter.
The conveyor is driven by an electric motor. The tensioning of the belt or the chain is mechanical or hydraulic. The length of the conveyor is from 1,0 to 6,0 m. There is a swinging taper roller just by the input in a debarker. It centres logs with the axis of the debarker. The frame of the conveyor swings up and down to adjust the height according to the log diameter. The aim is to insert logs in the very centre of the debarking rotor. There is a simple measuring of the diameter built on the conveyor. It is usually placed in front of the debarker with steady height of rotor.
The conveyor behind the debarker:
The conveyor is designed as a belt conveyor with a belt supported by roller idlers or as a longitudinal chain conveyor with a transport chain with lugs which moves on hardox slides. The frame is massive made of sectional steel and burnts, which supports the long operational life of the conveyor. The belt width is calculated according to the diameter of the logs. The type and rigidity of the belt or of the chain is calculated according to the transporting load capacity and the speed of the conveyor. The speed of the conveyor depends on the speed of a debarker and can be regulated by the frequency converter.
The conveyor is driven by an electric motor. The tensioning of the belt or the chain is mechanical or hydraulic. The length of the conveyor is from 1,0 to 6,0 m. The conveyor is placed behind the debarker. The following conveyor can be an infeed conveyor with ejector 109, 110, a conveyor for metal detector 115, or a log sorter 118.
