Kraft Corrugated Paper Recycling Process

• One of the first steps is pulping. To pulp the recycled kraft, Corrugated paper, the machine soak the waste and do primary pulping and screening.
• Next, to remove heavy impurities in paper pulp use cleaning equipment High density and Low density cleaner.
• Screening is the next step, use Mid consistency pressure screen to reject unwanted materials from paper pulp.
• Next is flotation or de-inking the paper pulp. This process involves the pulp slurry being mixed with a surfactant to collect and discard ink particles from the materials.
• A common next step is washing. This further cleans the pulp by passing water through it. Sometimes the pulp is then bleached, but only if a white color is desired in the end product.
