Br480rg Komatsu Crusher Specs

Demystifying the BR480RG-1 Komatsu Mobile Crusher: Powerhouse Performance in a Mobile Package

In the demanding world of aggregate production, demolition recycling, and large-scale construction projects, efficiency translates directly to profitability. Mobile crushers have revolutionized these industries by bringing crushing power directly to the material source or job site, drastically reducing hauling costs and operational complexity. Among these formidable machines stands the Komatsu BR480RG-1, a self-propelled impact crusher engineered for high-volume output and robust reliability in challenging conditions.

This article delves deep into the specifications of the Komatsu BR480RG-1 (often referenced as BR480RG), stripping away marketing gloss to provide a clear picture of its capabilities and limitations based on official Komatsu documentation and real-world performance expectations.

Core Concept: What is the BR480RG-1?

The BR480RG-1 belongs to Komatsu’s line of “Mobile Impact Crushers.” Unlike jaw crushers that compress rock between fixed and moving plates, impact crushers use high-speed rotors fitted with hammers/blow bars to shatter material through repeated impacts against breaker plates or other rocks within the crushing chamber (rock-on-rock principle). This makes them particularly effective for processing softer materials like limestone or recycled concrete/asphalt (RCA), producing a well-shaped cubical product desirable for many applications.

The “RG” designation signifies key features:
R = Remote Control System
G = Hydraulic Grizzly Feeder

These features are critical for operational efficiency and safety.
