Paper Shredding Blades

1.Waste paper recovery and recycling: The cutter ring pulverizer grinds waste paper boxes, newspapers and other materials into fiber flocs through high-speed rotating blades (rotating speed is 1500-3000rpm), and the output of a single machine reaches 0.08-1 ton/hour, which is suitable for the production demand of recycled pulp.

Jaw crusher uses the meshing structure of movable jaw plate and static jaw plate to treat waste paper containing impurities such as metals and stones, and the crushing efficiency is improved by 40%, which is suitable for the pretreatment scene of mixed waste paper.

2.Preparation of industrial grade pulp: The hammer mill is equipped with alloy steel hammer (hardness HRC55-58), which can quickly crush tough paper such as coated paper and straw paper, and the impurity rate of pulp is ≤0.5%. The waste paper shredder adopts a multi-blade combination design (the gap between blades is 0.5-2mm), which crushes the pulp board into 1-5mm particles and is directly used for the regeneration of papermaking raw materials.

3.High-precision special paper processing: cylindrical cutter set (serrated blade) with intelligent control system realizes paper crushing to 1×5mm particles, which conforms to ISO 21902-2 standard and adapts to the scene of confidential document destruction.

When the toothed blade is used to treat multi-layer composite paper, the fiber damage rate is reduced by staggered bite design, and the strength of recycled paper is ensured to be ≥ 80 N m/g.

4.Recycled paper manufacturing: the cutter ring pulverizer processes waste paper to generate pulp particles, which are directly used in the production of corrugated paper and cardboard, and the utilization rate of raw materials is increased to 98%.

Recycling of packaging materials: the toothed blade shreds the carton containing plastic film, and the separation purity of paper and plastic is more than 90%. 6. Field of environmental protection treatment: The volume of crushed paper scraps is reduced by 70%, and the transportation cost is reduced by 50%, which is suitable for urban solid waste treatment centers.

1.Ordinary paper: 9CrSi alloy steel with high cost performance;

2.High toughness/coated paper: Cr12mov or SKD-11 cold working die steel;

3. metal composite paper: cemented carbide blade, wear resistance is preferred.

4.low confidentiality: straight knife or serrated knife;

5.high security: spiral knife or multi-axis claw knife to achieve chip-level cutting.

6.high-frequency use: cemented carbide blade+periodic coating repair;

7.intermittent use: stainless steel blade+paraffin lubrication and rust prevention.

High-strength alloy steel: the blade is made of Cr12MoV (hardness HRC58-60) or 9CrSi tool steel, which has a wear-resistant life of 8000 hours and is suitable for high-strength continuous operation.

Surface strengthening technology:

Titanium nitride coating (TiN) reduces the friction coefficient of the blade by 35% and reduces the adhesion of paper scraps.

Laser cladding technology is used to repair the blade wear, and the service life of the repaired blade is restored to 80% of the new product.

Intelligent control system:

The overload protection device automatically reverses when the paper jams (the response time is less than 0.1 second), which reduces the frequency of downtime and maintenance.

Frequency conversion speed regulation technology automatically matches the speed according to the hardness of the material, which improves the energy saving efficiency by 25%.

Regular grinding: check the edge wear of alloy steel blades every 8 hours, and check the coating integrity of cemented carbide blades every 30 days;

Lubrication and paper jam prevention: use special lubricant to reduce blade friction and reduce the probability of paper jam;

Clearance adjustment: the clearance between the blade and the fixed blade is controlled at 0.1-0.3mm to avoid excessive extrusion and damage to the blade.

Through reasonable selection and scientific maintenance, the paper shredding knife can significantly improve the shredding efficiency and equipment life, and adapt to diverse scenes from office security to industrial recycling.
