Rubber Granulator Blade

1.Rubber waste recycling treatment: used to cut large pieces of waste such as waste tires and rubber products into uniform particles, which are reused as recycled rubber raw materials in the production line to reduce rubber resource consumption. Typical scenarios include recycled rubber manufacturing plants, rubber recycling enterprises, etc.

2.Preparation of new rubber materials: Accurately granulate modified rubber (such as composite materials with added carbon black and fibers) to ensure that the particle size meets the requirements of subsequent processes such as injection molding and extrusion.

3.Collaborative processing of mixed materials: Processing rubber waste containing metal inserts or plastic composites (such as sealing rings, conveyor belts), achieving impurity separation through granulation, and improving rubber purity.

High resistance running in steel (such as Cr12MoV) is suitable for continuous cutting of high elasticity natural rubber, while high-speed steel blades are more suitable for processing tire waste containing steel wire.

Special coating technology (such as titanium nitride) can reduce rubber adhesion and extend the service life of blades.

1.Daily maintenance

Cleaning: Clean the rubber residue on the surface of the blade every shift (assisted by a high-pressure air gun) to prevent melting and adhesion from affecting cutting accuracy.

Lubrication: Add lithium based grease to the blade shaft bearing every 50 hours to reduce metal fatigue wear.

2.Replacement cycle

Cr12MoV blade: 200-400 hours;

Hard alloy blade: 800-1200 hours.

Dynamic adjustment system: equipped with pressure sensors and intelligent control system, real-time optimization of blade clearance and speed.

Composite coating technology: tungsten carbide+diamond coated blades, with a 40% increase in wear resistance and an extended lifespan of up to 1500 hours.

Summary: Rubber granulator blades need to be selected comprehensively based on the type of raw material (pure rubber/impurities), production scale (continuous/intermittent), and cost control:

Economic type: Cr12MoV pellet rolling cutter;

Industrial grade: Hard alloy rolling cutters (wear-resistant priority) or steel embedded grinding knives (impact resistant priority);

Precision granulation: dynamic adjustment system+composite coating blade (technology upgrade plan).
