During in waste paper pulp coarse screen system, impurities will be removed step by step to meet the qualified standards and enter the next screening system. Whole set waste paper pulp coarse screen system include middle consistency coarse screen, low density cleaner, light impurity separator and reject separator. Coarse screen system details as below.

 

Waste Paper Pulp Coarse Screen System Flow

 

1. The pulp pump at the bottom of the unloading slurry tower transports the slurry to the medium consistency coarse screen with a hole for screening. The qualified accept pulp enters the first stage low density cleaner pump.
2. Impurities and unresolved pulp enter the light impurity separator for further re-resolving and removal, and the accept pulp goes to the coarse screen and the accept pulp chest.
3. The tailings of the light impurity separator are treated with a reject separator for the final treatment.
4. The reject separator can effectively separate light impurities and pulps and can perform secondary decontamination of incomplete fiber bundles.
5. The accept pulp from the reject separator flows to the pulp pump in front of the light impurity separator for a small cycle treatment, and the tailings are directly discharged from the system.

 

Waste paper pulp coarse screen system can effectively remove large pieces of light impurities of various shapes in the coarse pulp, obtain higher quality pulp, reduce the screening pressure of subsequent work sections, and have a low fiber loss rate.
