In the field of hard rock aggregate processing, when dealing with high-hardness, highly abrasive raw materials such as basalt and granite, configuring a high-efficiency, flexible crushing production line that produces high-quality aggregates with excellent particle shape is crucial for project profitability. When your project's raw material size reaches 630mm and requires the simultaneous production of four different sizes of high-quality aggregates, a scientifically designed two-stage tracked crushing solution is essential.
Based on extensive engineering experience, Baichi recommends the powerful combination of the YMC106 tracked jaw crusher and the YMC12S tracked impact crusher for such demanding conditions. This article will provide an in-depth analysis of how this configuration perfectly meets your production needs.
I. Project Challenges and Solutions
• Challenge 1: 630mm Large Hard Rock (Basalt/Granite)
◦ Solution: A powerful primary crushing unit is required. The YMC106 tracked jaw crusher features a robust frame and a carefully designed V-shaped crushing chamber, easily absorbing large raw materials for efficient and stable primary crushing, providing ideal feedstock for the secondary crushing stage.
• Challenge 2: Simultaneous production of four precise particle sizes: (0-5mm), (5-12mm), (12-19mm), and (19-32mm).
◦ Solution: A medium crushing unit with both shaping and fine crushing functions is required. The YMC12S tracked impact crusher is renowned for its excellent particle shape control capabilities, producing mostly cubic finished products. Combined with its built-in vibrating screen or a connected independent mobile screening station, precise grading and screening of four aggregate sizes can be easily achieved.
II. Detailed Explanation of Core Equipment Configuration: Why Choose YMC106 and YMC12S?
1. Primary Crushing: Baichi YMC106 Tracked Jaw Crusher Station – The Highly Efficient “Coarse Crushing Expert”
The YMC106 is the ideal starting point for coarse crushing of hard rock, and its design perfectly meets the needs of high-yield, high-efficiency mobile crushing.
• High Efficiency and Energy Saving: The optimized V-shaped crushing chamber angle enhances the crushing ratio, achieving higher production capacity with the same power, ensuring a stable and continuous material flow for subsequent stages.
• Compact and Mobility: The tracked chassis allows for flexible movement on the mining site, requiring no foundation installation and enabling rapid production, greatly improving site adaptability.
• Intelligent Control: Utilizing an intelligent control system, one-button start/stop and parameter setting make operation and maintenance exceptionally simple, reducing labor costs.
2. Secondary Crushing: Baichi YMC12S Tracked Impact Crusher – An Exceptional “Shaping Master”
The YMC12S undertakes the crucial tasks of medium and fine crushing and finished product particle shape control; its performance directly determines the quality and value of the final aggregate.
• Excellent Particle Shape, Multiplied Value: This is the core advantage of the impact crusher. YMC12S produces cubic particles with extremely low needle-like and flaky content. This aggregate exhibits higher compressive strength and adhesion, making it particularly suitable for high-grade aggregates, artificial sand production, and high-grade highway surface course materials, significantly increasing product added value.
• High crushing efficiency: It combines fine crushing and coarse grinding functions, offering strong processing capacity and effectively processing the semi-finished product from YMC106 crushing to the target particle size.
• Strong adaptability and reliable operation: It is not sensitive to material moisture content (up to 8%), reducing the risk of clogging. Its simple structural design facilitates maintenance and effectively controls long-term operating costs.
III. Process Flow and Advantages Summary
Simplified Process: Raw stone (≤630mm) → YMC106 (coarse crushing) → Intermediate material (approx. 0-250mm) → YMC12S (medium and fine crushing and shaping) → Vibrating screen → Obtaining four types of finished aggregates: 0-5mm, 5-12mm, 12-19mm, and 19-32mm.
Core Advantages of this Configuration:
• Highly Targeted: Specifically designed for high-hardness basalt and granite, with scientifically reliable equipment selection.
• High-Quality Finished Product: The impact crusher ensures excellent aggregate shape, meeting the demands of the high-end market.
• Flexible Mobility: The tracked design allows the production line to advance with the mining face, reducing material transportation costs.
• Rapid Commissioning: The equipment can be deployed and put into production in a short time after arrival on site.
For hard rock crushing projects with a capacity of around 200 tons per hour, the two-stage configuration of Baichi YMC106 and YMC12S is a proven, efficient, and economical solution. It not only overcomes the challenges of hard rock crushing but also produces high-value-added, high-quality aggregates, bringing substantial returns to investors. If you are planning such a project, this configuration is undoubtedly your ideal choice.
