Comprehensive Application Of Pulping Blades In The Paper Industry

1.Knife ring crusher blade: By high-speed rotating blades (speed 1500-3000rpm), waste paper boxes, newspapers and other materials are crushed into fibrous flocs, with a single machine output of 0.08-1 tons/hour, suitable for recycled pulp production lines.

2.Heavy duty shredder blade: When processing waste cardboard boxes containing plastic film, a multi blade staggered design (shear force ≥ 5000N) is adopted to achieve paper plastic separation purity ≥ 90%, which is suitable for composite packaging material recycling scenarios.

3.Hammer type blade (hardness HRC55-58) can quickly crush tough materials such as copperplate paper and medium grass paper, with pulp impurity rate ≤ 0.5%, suitable for high-strength continuous operation requirements.

4.The jaw crusher utilizes the meshing structure between the moving jaw plate and the stationary jaw plate to process mixed waste paper containing metal impurities, increasing crushing efficiency by 40% and reducing the difficulty of subsequent sorting.

Blade Material And Process Upgrade

Application of wear-resistant materials:

Cr12MoV alloy steel (hardness HRC58-60) is used for pulping blades, with a wear resistance life of up to 8000 hours and suitable for high-strength operations.

The wear resistance of tungsten carbide coated blades is improved by 50%, which is suitable for the high-speed cutting needs of circular cutting machines.

 

Blade Type And Optimized Design

1.Propeller blade: improves pulping efficiency through a spiral structure, reduces fiber entanglement, and is suitable for industrial grade waste paper processing lines;

2.Claw blade (multi axis): The dual axis/four axis staggered design enhances the tearing effect of cardboard and multi-layer corrugated paper, reducing motor load.

 

Industry Adaptability Analysis

1.Recycled paper manufacturing: The pulping equipment processes waste paper into pulp particles, which are directly used for the production of corrugated paper and box board paper, with a raw material utilization rate increased to 98%.

2.Packaging and printing industry: The round knife slitting machine is compatible with offset printing machines and flexographic printing machines, with a slitting accuracy of ± 0.05mm, meeting the cutting needs of label paper and irregular packaging.

3.In the field of environmental protection treatment: heavy-duty shredders can process mixed waste paper, reducing volume by 70% and transportation costs by 50%, suitable for urban solid waste treatment centers.

 

Maintenance Of Pulping Knife

1.Rust prevention treatment: Stainless steel blades should be sprayed with food grade rust inhibitor every 48 hours, and alloy steel blades should be regularly cleaned of fiber residues;

2.Wear detection: Check the integrity of the coating on hard alloy blades every month, and replace them immediately if any chipping is found.

Through precise selection and intelligent maintenance, the pulping and cutting blades can significantly improve the efficiency and quality of paper processing, adapting to diverse scenarios ranging from environmentally friendly recycling to high-precision industrial slitting.
