Bahasa IndonesiaIn aggregate manufacturing and mining ore reduction, cone crushers serve as critical equipment for secondary and tertiary crushing stages due to their high crushing ratios, robust efficiency, and broad material adaptability.
Currently, the market mainly offers three primary configurations: Spring Cone Crushers, Single-Cylinder Hydraulic Cone Crushers, and Multi-Cylinder Hydraulic Cone Crushers. These designs feature substantial differences in working principles, structural configurations, performance metrics, and application scenarios.
To help aggregate producers, quarry operators, and mining engineers choose the ideal crusher for their plant, Zhongxin Heavy Industry provides an in-depth, side-by-side technical evaluation across mainframe structures, discharge adjustments, overload protection systems, particle shaping, and maintenance costs.
1. Mainframe Structural Layout & Component Differences

The single-cylinder hydraulic cone crusher consists of a hydraulic cylinder assembly, lower frame, eccentric sleeve assembly, transmission system, inner cover, moving cone assembly, upper frame, and feeding hopper.
Featured Zhongxin Models: DP Series Single-Cylinder Cone Crusher, DPS Series Single-Cylinder Cone Crusher.
Multi-Cylinder Hydraulic Cone Crusher
The multi-cylinder hydraulic cone crusher comprises a main frame, transmission assembly, eccentric sleeve assembly, bowl-shaped bearing assembly, moving cone assembly, support sleeve, adjustment ring, and hydraulic clamping/release cylinder assembly.
Featured Zhongxin Model: XHP Series Multi-Cylinder Hydraulic Cone Crusher.
Symons & Compound Spring Cone Crusher
The Symons and compound spring cone crusher layout includes a main frame, eccentric sleeve assembly, drive unit, moving cone assembly, countershaft bowl assembly, support ring, adjustment cap, spring overload assembly, and hydraulic clearing cylinder unit.
Featured Zhongxin Models: Compound Cone Crusher, Symons Cone Crusher.
PY Series Spring Cone Crusher
The standard PY spring cone crusher consists of a main frame, eccentric sleeve assembly, transmission assembly, moving cone assembly, bowl bearing assembly, support ring, adjustment ring, and mechanical spring assembly.
Featured Zhongxin Models: PY1200, PY1750, PY2200 Spring Cone Crushers.
2. Discharge Opening (CSS) Adjustment Mechanisms
Single-Cylinder Hydraulic Cone Crusher: The closed-side setting (CSS) is adjusted by pumping hydraulic oil into or out of the bottom hydraulic cylinder. This raises or lowers the main shaft, dynamically changing the gap between the mantle and concave.
Multi-Cylinder Hydraulic Cone Crusher: A hydraulic pump powers a hydraulic motor that drives a pinion gear via electromagnetic directional valves. This rotates the large ring gear on the adjustment cap counter-clockwise or clockwise, screwing the adjustment ring up or down inside the support ring to change the CSS.
Symons, Compound, and PY1200/1750/2200 Spring Cone Crushers: A hydraulic pump feeds oil into push cylinders operated by manual control valves. The pushing head engages the notch ring on the adjustment cap, rotating the adjustment ring up or down inside the support sleeve. (Note: Compact models like PY600 and PY900 rely on manual mechanical adjustment).
3. Overload Protection & Tramp Iron Clearance (Unchoking)
Single-Cylinder Hydraulic Cone Crusher: When uncrushable tramp iron enters the chamber, hydraulic oil inside the cylinder is forced into an accumulator, lowering the main shaft. Once the obstruction clears, accumulator pressure restores the main shaft to its original position. During chamber clearing, hydraulic oil is drained from the cylinder, dropping the main shaft to open the chamber completely.
Multi-Cylinder Hydraulic Cone Crusher: Overload forces push hydraulic oil from the release cylinders into accumulators, allowing the support sleeve and adjustment ring to lift. After the tramp iron passes, accumulator pressure reseats the assembly. Chamber clearing is achieved by using the hydraulic system to pressurize the lift cylinders, raising the entire top section to discharge trapped material.
Symons & Compound Spring Cone Crushers: Mechanical springs compress to lift the support ring and adjustment cap when uncrushable material enters. For chamber clearing, hydraulic rams compress the springs to lift the top assembly by approximately 25 mm, widening the gap. Draining the rams allows the spring tension to crush remaining material—a process repeated until the chamber is cleared.
PY Spring Cone Crusher: Overload protection relies entirely on mechanical spring compression. Standard PY series crushers lack hydraulic clearing cylinders, requiring manual material excavation during chokes. (Zhongxin Heavy Industry provides optional hydraulic clearing cylinder upgrades for PY1200, PY1750, and PY2200 models upon request).
4. Bevel Gear Engineering & Drive Types
| Crusher Type | Bevel Gear Design | Manufacturing & Processing Engineering | Performance Characteristics |
| Single-Cylinder Hydraulic | Spiral Bevel Gear | Forging $\rightarrow$ Rough Turning $\rightarrow$ Heat Treatment $\rightarrow$ Precision Turning $\rightarrow$ Gear Cutting $\rightarrow$ Surface Quenching $\rightarrow$ Nitriding $\rightarrow$ Lapping & Precision Grinding | High power transmission efficiency, low operating noise, extended gear life. |
| Multi-Cylinder Hydraulic | Straight Bevel Gear | Forging $\rightarrow$ Rough Turning $\rightarrow$ Heat Treatment $\rightarrow$ Precision Turning $\rightarrow$ Gear Cutting $\rightarrow$ Surface Quenching $\rightarrow$ Nitriding | High load capacity, durable power transfer under heavy crushing forces. |
| Spring Cone Crusher | Counterweighted Straight Bevel Gear | Pinion: Forged, heat-treated, precision turned, gear-cut. Bull Gear: Cast, rough turned, heat-treated, precision planed. | Proven traditional design, simple manufacturing, reliable serviceability. |
5. Countershaft Bearings & Lubrication Systems
Single-Cylinder Hydraulic Cone Crusher: Uses rolling element bearings throughout the countershaft assembly. Models DP100, DP100S, DP430, and DP430S utilize oil bath lubrication, while heavy-duty models (DP440, DP440S, DP660, DP660S, DP780S, DP870, DP890, DP895) feature forced oil lubrication systems.
Multi-Cylinder Hydraulic Cone Crusher: Employs precision sliding bushings (journal bearings) with continuous forced circulating oil lubrication.
Symons Spring Cone Crusher: Uses bronze sliding journal bearings with forced circulating oil lubrication.
Compound Spring Cone Crusher: Utilizes anti-friction rolling bearings with oil bath lubrication.
PY Spring Cone Crusher Series: All PY models (PY600, PY900, PY1200, PY1750, PY2200) feature sliding journal bearings serviced by circulating oil lubrication stations.
6. Main Shaft Configuration & Mounting Differences
Single-Cylinder Hydraulic Cone Crusher: Features an elongated main shaft fixed directly into the moving cone torso. The lower end inserts into an eccentric copper sleeve resting on the hydraulic piston, while the upper end is supported by a top bushing in the upper frame. During operation, the main shaft gyrates along with the eccentric sleeve.
Spring Cone Crushers (PY, Symons, Compound): The main shaft is fixed to the moving cone core, inserted into an eccentric bronze sleeve, and supported at its base by a spherical socket bearing (bowl liner). It has no top support frame. The main shaft gyrates with the eccentric sleeve during crushing.
Multi-Cylinder Hydraulic Cone Crusher: Utilizes a short, heavy-duty stationary main shaft fixed directly to the main frame. The eccentric sleeve rotates around the stationary shaft, meaning the main shaft itself remains stationary during operation.
7. Feeding Requirements & Chamber Filling
Single-Cylinder Hydraulic Cone Crusher: Capable of handling choke feeding (full chamber feeding).
Multi-Cylinder Hydraulic Cone Crusher: Strictly requires choke feeding to maintain inter-particle compression and achieve optimal cubical product shaping.
Spring Cone Crusher: Feeding height only needs to reach the upper edge of the concave (mantle collar) without requiring strict choke-feed pressure.
8. Crushing Performance & Product Particle Shape
[Inter-Particle Compression (Multi-Cylinder)] ──► High Fines Output + Low Flakiness (<5%) ──► Hard Rock (Granite/Basalt) [High Throughput Reduction (Single-Cylinder)] ──► High Tonnage Flow + Coarser Fines ──► Soft / Weathered Ore [Standard Reduction (Spring Cone)] ──► Cost-Effective Secondary Reduction ──► Medium-Hard Aggregates
Multi-Cylinder Hydraulic Cone Crusher: Excel at inter-particle crushing (laminated crushing). Material is compressed against other rocks within the crushing chamber rather than just against manganese liners. This maximizes fine particle yield, yields cubical aggregate shaping, and reduces elongated/flaky particles to under 5%. It is the preferred choice for crushing hard and abrasive ores like granite, basalt, and iron ore.
Single-Cylinder Hydraulic Cone Crusher: Offers superior secondary crushing throughput. It provides larger pass-through capacities and faster material flow, though with a slightly higher percentage of flaky particles. It excels at processing softer ores, river gravel, and weathered rock where volume throughput is prioritized.
Spring Cone Crusher: Provides dependable primary-to-secondary crushing performance for non-critical aggregate applications at a lower initial equipment cost.
9. Maintenance & Operational Reliability Summary
| Crusher Category | Structural Complexity | Maintenance Requirements | Key Operational Advantages |
| Single-Cylinder Hydraulic | Simple (Single bottom cylinder) | Low failure rate, quick hydraulic adjustments | Easy maintenance, lower long-term operating cost, high throughput. |
| Multi-Cylinder Hydraulic | Moderate (Multiple hydraulic components) | Fast liner replacement, automated clearing | Full hydraulic tramp clearing and ring rotation save manual labor. |
| Spring Cone Series | Traditional Mechanical Setup | Mechanical spring inspection required | Simple mechanical operation, lower upfront capital expenditure (CAPEX). |
