Frequently Asked Questions
OCC Paper Dry Pulping Line FAQ
What does OCC mean in paper recycling?
OCC means old corrugated containers. In practical project discussions, it usually refers to recovered corrugated boxes, shipping cartons and similar corrugated packaging grades.
What is the direct output of this dry pulping line?
The direct output is loose or baled fiber-rich material recovered from OCC and suitable paper waste. It is not automatically a finished paper grade. Additional cleaning, refining, wet stock preparation or product-forming equipment may be required by the downstream application.
Is this the same as a conventional wet OCC stock preparation line?
No. This line uses mechanical shredding, dry fiber opening, impurity removal, dust control and collection. A conventional paper-mill OCC stock preparation line normally uses a hydrapulper, water circulation, screening, cleaning and stock preparation equipment.
Can baled OCC be fed directly into the line?
Baled OCC can be handled, but the bale condition determines the front-end configuration. Bale wire removal, bale opening, inspection and pre-sorting may be required before shredding.
Can the system process mixed paper waste?
Possibly, but mixed paper should be evaluated before equipment selection. Coatings, plastic film, wax, adhesives, moisture, textiles, metal and non-paper contaminants can change the process configuration and the quality of the recovered fiber.
How much water does the process use?
The core dry-processing section does not rely on a conventional high-water hydrapulper loop. Water demand still depends on the selected dust-control method and any downstream papermaking, molded-fiber or wet-cleaning process.
What determines production capacity?
Actual capacity depends on feed density, bale size, moisture, contaminant level, required shred size, desired fiber-opening degree, conveying arrangement and downstream collection method. Capacity should be confirmed from material data and, where practical, a sample test.
What contaminants should be removed before processing?
Large metal pieces, stones, wood, plastic bundles, ropes, textiles, liquid containers and other hard foreign objects should be removed. Ferrous pieces such as nails, staples and wire fragments can be captured by magnetic separation, but front-end inspection is still important.
How is dust controlled?
The production line can combine enclosed transfer points, controlled air extraction, dust collection and housekeeping access. The final design should also consider local requirements for combustible dust, fire detection, grounding and emergency isolation.
Can the output be used for papermaking or molded fiber products?
Recovered fiber may be used as feedstock for paper, packaging or molded-fiber applications when it meets the downstream process requirements. Final suitability must be confirmed through fiber testing and the specifications of the receiving process.
What information is needed for a quotation?
Provide representative material photos or samples, daily or hourly throughput, loose or baled feed form, bale dimensions, moisture and contaminants, required output condition, available workshop size, local voltage and the planned downstream use.
Can YUXI customize the line layout?
Yes. The equipment sequence, conveyors, sorting position, magnetic separation, buffer storage, dry pulping, dust collection, fiber collection, baling and control system can be configured around the material and plant layout.
