Multi-cylinder hydraulic and spring cone crusher
In the fields of mine crushing and construction aggregate production, the cone crusher is one of the most widely used secondary and fine crushing machines. Currently, the market is dominated by two main types: the Multi-cylinder Hydraulic Cone Crusher and the Spring Cone Crusher.
Many users face a dilemma during the procurement process: What exactly are the differences? What are their respective pros and cons? Which one fits my production line best? This article compares these two machines across three dimensions—Differences, Features, and Disadvantages—to help you make an informed investment decision.
I. Core Differences Between Multi-cylinder Hydraulic vs. Spring Cone Crushers
1. Safety Device: Hydraulic Cylinders vs. Springs
This is the fundamental structural difference. The multi-cylinder hydraulic type evolved from the spring type by replacing the traditional 10–16 sets of springs with 10–16 hydraulic safety cylinders.
Spring Cone Crusher: Relies on mechanical springs for tramp iron protection. When uncrushable objects enter the chamber, the impact compresses the springs, lifting the fixed cone seat to discharge the debris.
Multi-cylinder Hydraulic Cone Crusher:** Uses multiple hydraulic cylinders. The system releases pressure instantly when encountering hard objects, providing more sensitive and reliable protection.
2. Discharge Opening Adjustment: Manual vs. Automatic
Spring Cone Crusher: Adjusting the discharge port (CSS)requires adding/removing shims or manually rotating the adjustment ring. This is labor-intensive, time-consuming, and often requires multiple people.
Multi-cylinder Hydraulic Cone Crusher:** Controlled via the hydraulic system to lift or lower the fixed cone. Adjustments are precise, rapid, and can be done via a PLC touch screen without stopping the machine.
3. Cavity Clearing: Active vs. Passive
Multi-cylinder Hydraulic Cone Crusher: Features active hydraulic cavity clearing. It lifts the upper frame to clear blockages or iron pieces quickly and resets automatically.
Spring Cone Crusher: Uses passive clearing. While springs compress during overload, a complete stall usually requires manual labor to clear the chamber, followed by a tedious readjustment of the discharge opening.
II. Features and Disadvantages of Multi-cylinder Hydraulic Cone Crushers
Features:
1. High Efficiency and Large Capacity: It uses a fixed main shaft and optimized structure, resulting in 5%–15% higher efficiency and 35%–60% higher output than spring models.
2. Excellent Product Shape: Utilizes the inter-particle crushing principle (lamination crushing), which has a shaping effect. This increases the proportion of cubical products and significantly reduces needle-like (flaky) particles.
3. Automated Protection: The dual-way tramp iron release allows iron blocks to pass safely and resets immediately, ensuring continuous operation.
4. High Intelligence:Integrated PLC systems monitor oil temperature, pressure, flow, and load in real-time.
5. Easy Maintenance:Components can be disassembled from the top or side. The wear-resistant parts typically have a 30% longer service life.
Disadvantages:
1. Higher Price: The manufacturing cost is high. Market prices usually start above $30,000 (200,000 RMB), which may be a barrier for small-scale users.
2. Complex Structure: It has more components and requires a higher level of maintenance expertise compared to single-cylinder or spring models.
3. Hydraulic Oil Requirements: Requires high oil cleanliness; impurities can cause valve blockages.
III. Features and Disadvantages of Spring Cone Crushers
Features:
1. Low Investment Cost: The price is highly competitive, typically starting around $22,000 (150,000 RMB)
2. Versatility: Offers various chamber types (Standard, Medium, Short Head) across 15 models to meet different production needs.
3. Simple Maintenance: The structure is straightforward and robust, making it suitable for remote mining areas without specialized technicians.
4. Mature Technology:Used globally for over a century, technical support and spare parts are easily accessible.
Disadvantages:
1. Low Processing Efficiency: Cannot handle “full-feed” (choke feeding) conditions effectively, making it unsuitable for modern large-scale production lines.
2. Difficult Clearing: Chamber blockages require manual intervention and significant downtime.
3. Safety Risks:The protection stroke is small, which can occasionally lead to serious accidents like shaft breakage.
4. Inferior Grain Shape: Higher flaky content and lower precision in discharge size compared to hydraulic models.
IV. Selection Guide: Which One Should You Choose?
| Comparison | Spring Cone Crusher | Multi-cylinder Hydraulic Cone Crusher |
| Price | Lower (Budget-friendly) | Higher (Premium investment) |
| Efficiency | Moderate | High (35%-60% more output) |
| Product Shape| Average (Flaky) | Excellent (Cubical) |
| Protection | Mechanical (Slow) | Hydraulic (Automatic/Reliable) |
| Automation| Low | High (PLC/Remote Monitor) |
| Ideal Scenario | Small/Medium plants, soft-med rock | Large plants, hard rock (Basalt/Granite) |
Selection Recommendations:
Choose the Spring Cone Crusher if: You run a small-scale plant (approx. 200 tons/day), have a limited budget, and crush materials with medium hardness where grain shape isn’t the top priority.
Choose the Multi-cylinder Hydraulic Cone Crusher if: You operate a large-scale line (>1000 tons/day), process high-hardness materials (Basalt, Granite), and supply high-grade projects (High-speed rail, premium concrete) that demand strict cubical aggregates.
