Factory Direct Sale High Quality D2 SKD-11 Crusher Blades for High-speed Crushing of Wood Plastic and Metal

Made of Mn13 high-manganese steel, it possesses wear-hardening properties and extremely high impact resistance. Compatible with various jaw crushers, it is specifically designed for hard materials such as granite, limestone, and construction waste. The thickened structure, precision cast, enhances continuous operation capability and reduces maintenance costs.

Core advantage

Outstanding materials and heat treatment processes

High-carbon and high-chromium alloy tool steels such as D2, Cr12MoV, SKD-11, and 6CrW2Si are adopted, featuring extremely high hardness (above HRC 58-62), wear resistance, and certain impact toughness. It undergoes a complete process flow of vacuum quenching, multiple deep cryogenic treatments and high-temperature tempering.

Precision engineering design and structure

High-speed rotation is responsible for the main cutting and impact. Usually, stepped, helical or wolf-tooth designs are adopted to optimize the cutting Angle, reduce the load and noise. Fixed in the machine cavity, it forms an accurate shearing pair with the moving knife. Its gap is adjustable (usually 0.1-0.5mm), which is the key to controlling the particle size of the output.

Strong adaptability and customization capabilities

It is compatible with mainstream brand models at home and abroad (such as Wimeng, Sred, Jemicon, Andritz, etc.) and various specifications (single-axis, dual-axis, quad-axis, coarse crushing, fine crushing).

Safety and reliability guarantee

After assembly, each set of rotor blades undergoes high-precision dynamic balance testing (G6.3 grade or higher) to ensure smooth and vibration-free operation at high speeds, protect the main shaft and bearings, and reduce the overall failure rate of the machine.

Maintain convenience and service

The modular design supports individual replacement of blades or rotor assemblies, minimizing downtime to the greatest extent.

Facing industry pain points: Are your Blades currently encountering these challenges?

❌ Excessive wear: When handling hard and highly abrasive materials, the cutting edge rapidly becomes dull and needs to be replaced frequently.

❌ Accidental breakage: Encountering unbreakable objects or fatigue stress, causing the blade to crack and even damaging the main unit.

❌ Efficiency decline: After the blade wears out, the particle size of the crushed particles is uneven, production capacity drops, and unit energy consumption rises.

❌ downtime loss: Frequent replacement, commissioning and maintenance disrupt the production rhythm and cause huge opportunity cost.

❌ Vibration and noise: Blade imbalance or improper design can cause abnormal vibration of the equipment, threatening the overall stability.
