Technical details and manufacturing context for Crusher/Pulverizer

Definition

The Crusher/Pulverizer is a mechanical component used in road recycling machinery to process reclaimed asphalt pavement (RAP) and other road materials. It breaks down large chunks into uniform, reusable aggregate sizes through mechanical force and impact. The unit typically features a rotor with hammers, jaws, or impact plates that apply compressive and shearing forces. It is designed for integration into mobile or stationary recycling systems, handling feed sizes from 100 to 300 mm and producing discharge sizes adjustable between 10 and 50 mm via gap or screen settings. Rotor diameter ranges from 800 to 1200 mm, and rotor speed from 600 to 1500 rpm, with higher speeds increasing the reduction ratio. Capacity varies from 5 to 50 t/h depending on material hardness, and motor power ranges from 15 to 90 kW. Operating voltage is three-phase AC at 380–690 V per IEC 60038, and operating temperature is -20 to 40 °C. Ingress protection is rated IP54–IP65 per IEC 60529 for dusty environments. Blade material is high-chromium alloy steel, manganese steel, or hardened tool steel, with a specific grade Cr12MoV per GB/T 1299 for high wear resistance. Machine weight ranges from 1500 to 5000 kg, affecting installation and transport. Noise level is 85–95 dB(A) per ISO 3744, requiring hearing protection above 85 dB. These values are reference ranges; verify model-specific specifications and standards with the legal manufacturer or supplier before procurement or use.

Working Principle

The crusher/pulverizer operates by rotating a rotor equipped with hammers, jaws, or impact plates at high speed. Road materials are fed into the crushing chamber, where they are struck by the rotating elements, applying compressive and shearing forces. The impact breaks the material into smaller fragments, which are further reduced as they collide with impact plates or are forced through a screen or gap at the discharge. The rotor speed and gap size determine the final particle size distribution. Mechanical fragmentation and impact crushing reduce the material to specified sizes, enabling recycling of RAP and other road materials.

Frequently Asked Questions

What is the typical feed size for this crusher/pulverizer?

The feed size range is 100–300 mm, meaning the maximum input dimension of the material should be within this range. Larger materials may need pre-crushing or screening.

How is the discharge size adjusted?

Discharge size is adjustable via gap settings or screen changes, typically ranging from 10 to 50 mm. The specific adjustment mechanism depends on the model; consult the manufacturer's manual.

What materials are used for the crushing elements?

The crushing elements are made from high-chromium alloy steel, manganese steel, or hardened tool steel. A specific grade, Cr12MoV per GB/T 1299, is listed for high wear resistance.

What are the operating voltage and protection requirements?

The operating voltage is three-phase AC at 380–690 V per IEC 60038. Ingress protection is rated IP54–IP65 per IEC 60529, with higher ratings recommended for dusty environments.
