Black contamination on the face of the rolls

Grinding dust, or black contamination on the faces of the rolls is mainly transferred from the blade. It is usually caused by a combination of:

• Grinding dust (especially graphite in the bond creates dark grey dust)
• Lubrication process => because of the oil the dust sticks on the blade
• Metal particles => check the magnetism of the log saw blades

We recommend:

• Regular cleaning of the saw house
• Grinding wheels with less graphite content => TKM Group wheels do not have any graphite, the dust is light.
• A quality Lubrication system such as that provided by the TKM Group because it needs much less spray frequency and –time.
• Felt wipers can be installed on some machines that constantly wipe the surface of the blade clean.
