The Biggest Used Jaw Crushers in the World: Giants of Secondary Markets

While the title of "the biggest in the world" often belongs to newly commissioned mega-machines in mining operations, the market for used equipment has its own titans. This article explores the realm of the largest used jaw crushers that have been available for resale or have changed hands in recent years. These are not mere prototypes but proven industrial workhorses, often from decommissioned mines or upgraded processing plants, seeking a second life. We will examine their specifications, typical applications, and what makes such colossal used machinery a significant investment.

The primary candidates for the biggest used jaw crushers typically stem from renowned manufacturers known for their ultra-class models: Metso (now Metso Outotec), Terex (and later Terex® MPS), and FLSmidth. Models like the Metso Nordberg C200, C160, and the even larger C200 series are frequent contenders. Perhaps the most iconic in the used market landscape is the Terex Cedarapids JS Series, with models like the JS4552, featuring a massive 55" x 32" (1397 x 813 mm) jaw opening. Another notable giant is the FLSmidth Fuller-Traylor® NT Gyratory Crusher, though technically a gyratory, it is often categorized with large primary jaw crushers due to its similar function at the head of a crushing circuit.

Purchasing such a used giant involves weighing significant factors against newer, possibly smaller, alternatives.

Feature	Pros of a Largest Used Jaw Crusher	Cons & Considerations
Cost	Drastically lower capital expenditure (CapEx) compared to a new equivalent. Often sold at a fraction of original price.	High potential refurbishment and transportation costs. May require new wear parts immediately.
Capacity	Offers proven, high-tonnage throughput (often 1,000-2,000+ tph capable) for large-scale projects.	Efficiency may be slightly lower than newer models due to advancements in chamber design and kinematics.
Availability	Can be acquired and deployed faster than waiting for a new machine's manufacturing lead time.	Limited availability; specific models are rare finds.
Durability	Built with heavy-duty designs from proven platforms; "over-engineered" by some modern standards.	Component fatigue is unknown; requires thorough inspection of frame, bearings, and shaft for cracks or stress.
Technology	Robust and mechanically simple control systems.	Lacks modern automation features, telematics, and advanced safety systems found on new crushers.

Real-World Case: The Secondary Giant in Quarry Expansion

A prominent limestone quarry operator in North America faced the need to double primary crushing capacity but had strict budget constraints. Instead of purchasing a new primary jaw crusher costing several million dollars, they sourced a used Metso Nordberg C160 jaw crusher from a closing iron ore processing facility in another region.

The process involved:

1. Inspection & Audit: A team of engineers inspected the crusher in situ, checking critical components like the main frame for weld integrity, pitman shaft bearings, and toggle plate seats.
2. Refurbishment: The crusher was partially dismantled at its original site. The worn jaw dies were discarded, bearings were inspected and repacked, and all seals were replaced.
3. Transport & Installation: The massive components were transported via specialized heavy haulage to the quarry where a new foundation had been prepared based on original manufacturer drawings.
4. Integration: The crusher was fitted with new manganese jaws and connected to an updated motor drive and basic starter system.

The result was a successful capacity increase at approximately 40% of the cost of a new machine, allowing the quarry to meet its production goals within two years instead of three.

Frequently Asked Questions (FAQs)

Q1: What is realistically considered one of the biggest used jaw crushers available on the market?
A: While inventory changes frequently, units like the Terex Cedarapids JS4552 or Metso Nordberg C200/C160 series are among the largest typically offered in resale markets from major dealers like MachineryTrader or through industrial auction houses.

Q2: What are the biggest risks when buying such large used crushing equipment?
A: The foremost risks are hidden structural fatigue or cracks in critical cast components (like main frame or pitman) that are costly to repair, undocumented major bearing damage from previous operation under shock loads, and misalignment issues that can cause premature failure.

Q3: Is finding replacement parts for these older giant models difficult?
A: For major OEM models (Metso/Nordberg, Terex Cedarapids), core wear parts like jaw dies, cheek plates,and toggle plates are generally not an issue as they are often still manufactured or have aftermarket equivalents.Common mechanical components (bearings,bushings)are standard items.The challenge can arise with proprietary castings or obsolete electrical components which may require reverse engineering.

Q4: Can these old large jaws be integrated with modern automated control systems?
A: Yes,a common practice is retrofitting.Modern PLC-based control systems,variable frequency drives(VFDs)for motor control,and automatic lubrication systems can be added.This upgrades safety,efficiency,and monitoring capabilities while retainingthe core mechanical structure.

Q5:What type of buyer typically invests in these machines?
A:The typical buyers are established mid-to-large size quarry operators,civil contractors handling mega-projects(e.g.,dam construction requiring aggregate production on-site),or specialized recycling companies processing concrete and demolition waste at very high volumes.They possessthe technical expertise,facilities,and capital reservesfor necessary refurbishment
