Mobile Jaw and Cone Crusher YG938E69: A Comprehensive Overview
The YG938E69 is a specific model of mobile crushing plant that integrates a primary jaw crusher and a secondary cone crusher onto a single, track-mounted chassis. It is designed as a two-stage crushing system for medium-hard to hard rock and recycled concrete applications. The following details are based on publicly available technical specifications and industry-standard configurations for this model family.
1. Core Configuration: Two-Stage Crushing Process
The defining feature of the YG938E69 is its sequential crushing setup:
- Primary Stage: A robust jaw crusher, typically a model like the PE600×900. This crusher performs the initial, heavy-duty reduction of feed material (with a maximum feed size generally around 500mm), producing a coarse aggregate.
- Secondary Stage: A cone crusher, often specified as the CS160 or similar. It receives the pre-crushed material from the jaw crusher via an integrated belt conveyor system. The cone crusher provides precise, inter-particle crushing to produce well-shaped, finer final products.
This combination allows for high reduction ratios and the production of multiple, spec-compliant aggregate fractions in a single pass.
2. Mobility and Deployment
Built on a heavy-duty crawler track undercarriage, the YG938E69 is designed for high mobility on-site. Key mobility features include:
- Hydraulic drive system for track movement, enabling low-speed maneuvering and on-site positioning without the need for external tow equipment.
- A compact transport configuration where the integrated conveyors are folded hydraulically to meet standard road transportation dimensions.
- Fast setup times, typically requiring only levelling of the unit upon arrival at the crushing location.
This makes it suitable for contract crushing, quarrying, and mining operations where the site changes periodically.
3. Key Technical Parameters (Representative Values)
While exact figures can vary slightly based on specific market configurations, common published parameters include:
- Jaw Crusher Feed Opening: Approximately 600mm x 900mm.
- Cone Crusher Model: Medium-coarse cavity type, such as CS160 (also known as PYB1750 in some standards).
- Engine: A high-power diesel engine (e.g., Cummins or equivalent) meeting Tier III/Stage IIIA emission standards, providing power for both tracks and crushers.
- Capacity: Estimated throughput ranging from 70 to 180 tonnes per hour, heavily dependent on feed material characteristics (hardness, abrasiveness, size) and final product size settings.
- Main Discharge Conveyors: Equipped with adjustable height radial conveyors for stockpiling finished products.
4. Primary Applications
The plant is engineered for:
- Natural Rock Crushing: Processing granite, basalt, limestone, and other aggregates.
- Construction & Demolition Waste Recycling: Crushing reinforced concrete, asphalt slabs, and building rubble.
- Mining Operations: Serving as a primary crushing unit in small to medium-scale mining projects.
Its design prioritizes flexibility to move between different faces in a quarry or between different demolition sites within an urban area..jpg)
5. Operational Advantages.jpg)
Documented benefits from user reports and technical analyses highlight:
- Integrated Efficiency: Eliminates the need for separate prime movers (excavators or wheel loaders) to shuttle material between standalone primary and secondary crushers, reducing fuel consumption and operational manpower.
- Reduced Logistics: Moving one integrated unit instead of two separate machines lowers transport costs between sites.
- Compact Production Line: All essential crushing stages—feeding (via vibrating feeder), primary crushing, secondary crushing, screening (with optional attached screen), and stockpiling—are contained within one continuous flow on a single chassis.
In summary, the mobile jaw and cone crusher YG938E69 represents a specific engineering solution that combines primary reduction and secondary refinement capabilities in a mobile format. Its design focuses on providing contractors with a balance of production capacity, final product quality control through two-stage crushing, and rapid relocation flexibility for diverse aggregate production tasks.
