A typical OCC repulper consists of a vat, rotor inside the vat, one or more pumps each with an extraction plate, a junk trap, and a ragger. The OCC bales are typically fed into the repulper vat by a conveyor system along with a measured amount of dilution water. The rotor positioned at the bottom or side of the vat is used to break up the OCC into separate fibers suspended in the water. The ragger and junk trap are used to collect and remove large contaminants from the top and bottom of the vat respectively, and the extraction plates are used to screen the slushed pulp as it exits the vat in order to protect downstream equipment. The OCC pulp is then pumped to the next process step.
