Jaw Crusher on Tracks: The Ultimate Mobile Crushing Solution
A Jaw Crusher on Tracks, commonly known as a mobile jaw crusher or tracked jaw plant, is a self-propelled primary crushing machine that combines the robust crushing power of a conventional jaw crusher with the high mobility of a crawler undercarriage. It is designed to be driven directly to the material source, such as a quarry face or a demolition site, eliminating the need for stationary foundations and expensive transportation of material
The Core Role and Key Applications
The primary role of a jaw crusher on tracks is to provide high-capacity primary crushing directly at the source. This capability is invaluable across several industries:
Quarrying & Mining: Moving between different faces or pits to process material, significantly reducing truck haulage costs.
Construction & Demolition (C&D): Crushing concrete, asphalt, and rubble directly on the demolition site, creating valuable recycled aggregate for new projects.
Contract Crushing: Ideal for contractors who need to set up and dismantle operations quickly across multiple job sites.
Infrastructure Projects: Crushing natural rock for road base and other materials right where it’s needed, such as for highway or railway construction.
Key Features and Problems It Solves
The design of a tracked jaw crusher incorporates features that solve common logistical and operational challenges:
Unmatched Mobility: Crawler tracks allow movement on rough and uneven terrain, reaching locations inaccessible to trucks or static plants.
Rapid Setup and Teardown: The plant is operational within minutes of arriving on site, requiring minimal setup compared to fixed foundations.
Elimination of Haulage Costs: By processing material on-site, it removes the need and cost of transporting large raw material to a fixed crusher.
Versatility in Feeding: Can be fed directly by a wheel loader or an excavator.
Power Source Options
Tracked jaw crushers are typically powered in one of two ways:
Diesel-Hydraulic Drive: A high-horsepower diesel engine powers a hydraulic system that drives both the tracks for mobility and the jaw crusher for crushing. This is the most common configuration, offering complete independence from external power sources.
Electric Drive (Diesel-Electric or Direct Grid Connection): Some larger models use a diesel engine to generate electricity (diesel-electric) or can be plugged directly into the grid. This is more fuel-efficient for long-term, fixed-location projects within a site and reduces noise and emissions.
Model and Parameter Table
The following table provides a general overview of common tracked jaw crusher models. Exact specifications vary by manufacturer.
| Model Size | Approx. Weight (Tons) | Jaw Crusher Feed Opening | Approx. Capacity (TPH) | Power Source | Primary Application |
|---|---|---|---|---|---|
| Compact | 25 – 35 | 800 x 500 mm | 150 – 220 | Diesel-Hydraulic | Urban C&D, Small Quarries |
| Medium | 40 – 55 | 1000 x 600 mm | 250 – 350 | Diesel-Hydraulic | Quarrying, Large C&D sites |
| Large | 55 – 70 | 1100 x 700 mm | 350 – 450 | Diesel-Hydraulic / Electric | Large Quarries, Mining |
| High-Capacity | 70+ | 1200 x 800 mm+ | 450 – 600+ | Electric (Diesel-Electric) | Major Mining, Mega Projects |
Additional Considerations for Your Operation
Integrated Fines Screening: Many models feature an integrated pre-screen to remove fine material before it enters the crusher, increasing efficiency and reducing wear.
Magnetic Separator: An over-band magnet is a common option to remove rebar and other metal from crushed C&D material
Dust Suppression System: Water spray systems are crucial for controlling dust, especially in urban environments or sensitive areas
Conclusion: Is a Tracked Jaw Crusher Right for You?
If your operation involves multiple sites, remote locations, or requires maximum flexibility and on-site processing, a jaw crusher on tracks is the most efficient and cost-effective solution. It transforms raw material into valuable product right where it lies, turning logistical challenges into profitable opportunities
