Broke is an important byproduct of the papermaking process that is reclaimed and recycled back into the furnish. Broke is generated at various points around a paper machine and so repulpers are positioned in both under-machine and off-machine locations to collect, repulp, and pump the broke back to the stock system for reuse in the paper or board making process. This course covers the safety hazards around broke repulpers, off-machine repulper designs, the broke repulping process, as well as repulper consistency control.
