BENEFITS

  • Reduces the initial investment costs.
  • Avoids expensive daily maintenance and constant preventative maintenance.
  • Eliminates jams and waste due to crooked or knotted logs.
  • Reduces downtime.
  • Eliminates costly replacement of “chippers”.

OPERATION

A diesel powered high pressure pump proves effective in removing bark from freshly cut white oak. This high pressure debarker follows the line of the bark and avoids costly downtime due to jams common in mechanical debarkers.

 

Mechanical debarking has been the best known means of removing bark, however it has many shortcomings. The initial cost and the expensive tungsten carbide chippers must be replaced every three days. Mechanical devices require constant preventative maintenance and are easily jammed with crooked or knotted logs.

 

17 lpm, 340 Kg/cm2 pump and a 0° nozzle can effectively remove bark from freshly cut white oak. Using high pressure water for debarking eliminates timely and costly jams, cleans the logs before milling, increases saw blade life, provides better paper products and a cleaner operation for reduced costs.
