Information

  The function of high-quality waste paper pulper: through the agitation, shearing and mechanical action of the water body, the wood pulp or waste paper raw materials are broken into fiber bundles or single fibers, while maintaining the original shape and strength of impurities to the greatest extent.

quality waste paper pulper

  Factors affecting the performance of high-quality waste paper pulper: 1. Rotor structure; 2. Pulp tank structure; 3. Pulp temperature; 4. PH value; 5. Pulp concentration; 6. Pulp time.

  At present, there are three main types of high-quality waste paper pulpers used in my country: vertical high-consistency pulper, vertical low-consistency pulper, and rotary drum pulper.

  1. High-quality waste paper pulper vertical high-consistency pulper

  1. Description

  High-quality waste paper pulper The high-consistency pulper has a working concentration of 10-20%, and is especially suitable for deinking pulp production lines that need to add chemicals. Most of the high-consistency pulpers work intermittently. Intermittent pulping requires 100% disintegration of fibers and sufficient time for chemicals or heating. Intermittent operation under high-consistency is beneficial to provide intense fiber-to-fiber friction, especially In the deinking system, the ink is peeled off from the fiber surface to remove the ink particles.

  2. Workflow

  The high-consistency pulper of high-quality waste paper pulper works intermittently for about 30 minutes. The crushing process is roughly: 1. Water injection for 5 minutes, and chemicals are added simultaneously; 2. Feeding for 3 minutes; 3. Pulp 15- 18 minutes; 4. Dilute to 4-5% concentration by secondary water injection for 3 minutes; 5. Put slurry for 5 minutes; 6. Rinse the tank to discharge coarse slag for 2 minutes.
