used jaw crushers machines for sale
Industry Background: The Robust Market for Pre-Owned Crushing Equipment
The global mining, quarrying, and construction industries are capital-intensive sectors where equipment acquisition represents a significant financial outlay. In this context, the market for used industrial machinery, particularly used jaw crushers, has matured into a vital and sophisticated segment. Primary challenges driving this trend include volatile commodity prices, tightening project budgets, and the need for rapid deployment of processing capacity. For many small-to-medium-sized enterprises (SMEs) or contractors undertaking short-term projects, investing in a new primary crusher is often economically unviable. The used jaw crusher market offers a compelling alternative, providing access to robust, proven technology at a fraction of the cost. However, this market is not without its own challenges; buyers must navigate concerns regarding equipment remaining life, maintenance history, wear part condition, and compatibility with modern safety and automation standards.
Core Product/Technology: What Defines a Modern Used Jaw Crusher?.jpg)
A jaw crusher is a primary compression-type crusher that reduces large rocks by forcing them between a stationary and a moving jaw plate. The core value proposition of a used machine lies in its retained engineering integrity and performance potential.
- Key Components & Architecture: The fundamental components are the fixed jaw (often called the cheek plate), the movable jaw, the eccentric shaft that drives the movable jaw in an elliptical motion, toggle plates that act as a safety mechanism, and heavy-duty bearings. The "crushing chamber" geometry is critical for efficiency and product shape.
- Critical Assessment Points: When evaluating a used jaw crusher, several technical aspects are scrutinized:
- Jaw Dies: The condition of the manganese steel jaw plates is paramount. Their wear profile directly impacts capacity and product gradation.
- Frame & Structure: The main crusher frame must be inspected for cracks or signs of fatigue welding.
- Eccentric Shaft & Bearings: These are the heart of the machine. Proper lubrication history and absence of play or overheating are non-negotiable.
- Drive System: This includes sheaves, V-belts, and sometimes hydraulic components for setting adjustment.
Modernization is a key trend. Many used crushers can be retrofitted with new features that enhance their value:
- Automated Setting Regulation: Hydraulic toggle systems allow for quick and easy adjustment of the closed-side setting (CSS), enabling operators to change product size without downtime for manual shim adjustment.
- Wear Monitoring Systems: Ultrasonic or laser-based sensors can be installed to monitor liner wear in real-time.
- Condition Monitoring Ports: Integration points for vibration sensors on bearings help facilitate predictive maintenance strategies.
Market & Applications: Where Do Used Jaw Crushers Deliver Value?
The application spectrum for used jaw crushers is broad, mirroring that of new units but with a focus on cost-effectiveness and flexibility.
| Application/Industry | Primary Use Case | Key Benefits of a Used Machine |
|---|---|---|
| Quarrying & Aggregates | Primary reduction of blasted limestone, granite, or basalt to a manageable size for secondary crushing. | High uptime availability from proven designs; lower cost-per-ton enables competitive bidding on aggregate supply contracts. |
| Mining | Primary crushing of run-of-mine (ROM) materials like copper ore or gold-bearing rock. | Rapid deployment to process initial ore from a new pit while permanent facilities are being built. |
| Construction & Demolition (C&D) Recycling | Crushing concrete rubble, asphalt, and bricks to create recycled aggregate for road base or backfill. | Ideal project-specific solution; rugged construction handles abrasive materials; payback period is significantly shorter than with new equipment. |
| Rental Fleets | Providing temporary crushing solutions for contractors. | A diverse fleet of used machines can be assembled to meet various client needs without the capital outlay of an all-new fleet. |
Measurable benefits include:
- Capital Expenditure Reduction: Savings of 40% to 60% compared to an equivalent new machine are common.
- Proven Reliability: Many older models have decades of operational history proving their durability.
- Parts Availability: For established models like Metso Nordberg C Series or Terex Jaques, replacement parts are readily available globally.
Future Outlook: Trends Shaping the Secondary Crusher Market
The market for used jaw crushers is evolving from a simple "as-is" marketplace to one characterized by value-added services and technological integration.
- Certified Rebuild Programs: Leading OEMs and specialized dealers are offering certified refurbishment programs where used machines are completely disassembled, inspected, re-machined as needed, fitted with new wear parts and bearings, and repainted—effectively offering "like-new" performance with a warranty.
- Digitalization & Data Integration: The ability to retrofit used crushers with IoT sensors will become standard. Data on throughput power consumption CSS adjustments will feed into fleet management systems optimizing overall plant performance
3 Sustainability Focus: Using recycled machinery aligns perfectly with corporate sustainability goals by extending product lifecycles reducing waste from manufacturing new units (embodied carbon) promoting circular economy principles within heavy industry

FAQ Section.jpg)
- What is the most important thing to check when buying a used jaw crusher?
Beyond visible condition request documented evidence of maintenance history particularly for lubrication schedules The eccentric shaft bearings are arguably most critical component; their replacement is costly so proof proper care essential
2 How much life can I expect from well maintained used jaw crusher
A high quality jaw crusher built major OEM has virtually indefinite structural life provided frame intact Key wearing components like jaw dies bearings toggle plates require regular replacement With proper maintenance rebuilds core components machine can operate reliably for several decades
3 Are there disadvantages buying older model versus newer used one
Older models may lack modern safety features like non contact tramp iron protection hydraulic setting adjustment They might also less energy efficient due dated motor drive designs However they often simpler maintain repair potentially more robustly built than some contemporary equivalents
4 Can used jaw crusher be automated integrated into modern processing plant
Yes absolutely Modern PLCs SCADA systems can be interfaced with older crushers Retrofitting variable frequency drives VFDs allows soft starting precise control motor speed optimizing power consumption particle shape
5 What hidden costs should budget when purchasing
Always budget immediate replacement wear parts jaws side liners upon delivery Factor potential re machining mating surfaces re alignment drive system shipping costs import duties if applicable
Case Study / Engineering Example: Boosting Quarry Output with Strategic Used Equipment Investment
Project Background:
A regional quarry operator in Texas USA was facing capacity constraints at its primary crushing stage Its existing single toggle jaw crusher from early 2000s was struggling meet growing demand aggregates for local road construction projects Capital budget did not allow purchase new primary unit which would have exceeded $1 million
Solution Implemented:
After thorough technical evaluation company sourced certified refurbished 2015 model Metso C125 Jaw Crusher through specialized dealer Machine had recorded 6 operating hours since major overhaul which included:
- Complete disassembly cleaning
- Magnaflux inspection frame shaft
- Replacement all bearings seals

- Retrofit hydraulic setting adjustment system
Total investment $450000 representing approximately 55% savings versus equivalent new model
Measurable Outcomes:
The refurbished C125 was installed during planned two week plant shutdown Post implementation results over six month period were tracked against previous performance:
| Metric | Before (Old Crusher) | After (Used C125) | Change |
|---|---|---|---|
| Average Throughput (tph) | 280 tph | 355 tph | +26% |
| Power Consumption (kWh/t) | 0.85 kWh/t | 0.72 kWh/t | -15% |
