How Blade Quality Affects Slow Speed Crushing Efficiency?

In modern injection molding, good slow-speed crusher blades make beside-the-press recycling more efficient.High-speed granulators use impact.Slow-speed systems (25–30 RPM) use high-torque shearing.They need special steel to cut plastic cleanly.

The Metallurgy of Low-RPM Shearing

Low-speed blades work under high pressure with little cooling air.Material choice is very important.

Top blades use SKD-11 or D2 tool steel.They are vacuum-hardened to HRC 58–60.This hardness stops the cutting edge from deforming.It works well with glass-filled plastics and strong engineering resins.It keeps a steady gap between the rotor and stator.

Blades are the most important consumable in recycling.High-quality alloy steel and precision grinding make your system clean, quiet, and profitable.

Slow-Speed Plastic Crusher

A slow-speed beside-the-press crusher is made for injection molding areas.It runs at low RPM, low noise, and low dust.It is perfect for recycling sprues and defective parts right away.

Product Features

Low speed: 28–300 RPM.

Less heat, no melting, better recycled material.

Quiet: Soundproof cabinet and sound-absorbing cotton.

Meets industrial noise standards.

No screen: Uniform particles, little powder.

Can mix directly with new material.

Strong blades: SKD-11 and imported steel.

Wear-resistant, long service life.

Automatic feeding: Available on some models for higher efficiency.

Applications

Injection molding recycling: Sprue and reject recycling.

Hard plastics: PC, Nylon, ABS, etc.

Soft plastics: LDPE film, PP woven bags (on selected models).
