The Belt conveyor for metal detector detects the pieces of metal in logs. It is situated behind a log conveyor with one or two chains 106, 107. In the area of the metal detector the belt is lead on the plastic skid plates in a wooden trough. The front and the end part of the conveyor as well as the driving and tension stations are made of steel.
The type and rigidity of the belt is calculated according to the transporting load capacity and the speed of the conveyor. The belt width is calculated according to the diameter of the logs. The belt is driven by an electric motor and a drive pulley. The tensioning of the belt is provided by a tensioning pulley. The speed can be regulated by the frequency converter. The length of the belt conveyor is ca. 6,0 m.
The size of the metal detector is calculated according to the log diameter and the length of the metal-free zone is calculated according to the size of the metal detector. The following conveyor can be an infeed conveyor with ejector 109, 110, or a log sorter 118.
