European-Style C-Series Hydraulic Jaw Crusher
Primary stone crushing is the first stage of the entire crushing production line and directly determines downstream capacity and cost-per-ton. Featuring a deep V-shaped crushing chamber and a hydraulic wedge-based discharge opening adjustment system, the European-style C-Series hydraulic jaw crusher delivers both high throughput and low energy consumption per ton when processing hard materials like granite, basalt, and river pebbles. It reduces discharge opening adjustment time from hours to minutes and boosts capacity by 10–15% compared to traditional jaw crushers at the same power level, making it one of the most cost-effective solutions for primary crushing.
I. Overview: What is the C-Series Hydraulic Jaw Crusher?
The European-style C-Series hydraulic jaw crusher is a second-generation model designed for large-scale primary stone crushing. It utilizes a symmetrical, deep-chamber structure characterized by a deep crushing cavity and a small nip angle; materials undergo thorough compression and bending within the chamber before discharge, resulting in more uniform output size and a lower content of needle- and flake-shaped particles. Compared to older PE-series jaw crushers, there are two key differences: first, the hydraulic wedge discharge opening adjustment system allows operators to set and adjust the opening online within minutes, eliminating the need to manually install or remove shims; second, the modular, weld-free frame allows for sectional transport and on-site bolted assembly, significantly shortening installation and relocation times.
It is suitable for materials with compressive strengths up to 320 MPa—including limestone, granite, basalt, diabase, river pebbles, and iron ore—and serves three major sectors: sand and aggregate production, mineral processing, and construction waste recycling. The entire series is compatible with various regional power standards, including 380V, 400V, and 440V/60Hz.
II. Typical Application Scenarios
2.1 Primary Crushing in Hard Rock Mines
Blasted run-of-mine (ROM) hard rock—such as granite or basalt—often features lump sizes of 500–700 mm. Large models like the C116 and C120 are installed directly between the mine bin and the conveyor belt, crushing the raw ore in a single pass to a feed size suitable for downstream cone crushers or ball mills. Under the "more crushing, less grinding" process philosophy, a stable coarse crushing output size directly improves mill hourly throughput and reduces the cost per ton of ore for the entire plant.
2.2 Primary Crushing in Aggregate Production Lines
For limestone and river pebble quarries as well as manufactured sand production lines, C96 and C106 models handle the primary coarse crushing stage. Combined with cone crushers for secondary crushing and VSI crushers for sand making and shaping, they form a complete three-stage process ("jaw crusher + cone crusher + sand maker"). The resulting product features stable gradation, meeting aggregate standards for highway construction and commercial concrete plants.
2.3 Core Units for Mobile Crushing Stations
Thanks to their modular frames and compact layouts, C-series crushers serve as the ideal "heart" for tracked and wheeled mobile crushing stations. They allow for flexible combinations with screening and feeding units and enable rapid site relocation, making them suitable for temporary material yards, tunnel muck processing, and post-disaster reconstruction projects.
2.4 Recycling of Construction Waste and Tunnel Muck
In the recycling of construction waste and mine overburden, the C-series demonstrates strong adaptability to mixed materials containing rebar and impurities, featuring impact-resistant jaw plates. It can coarsely crush waste concrete and tunnel muck before the material proceeds to iron removal and secondary crushing stages, thereby facilitating resource recovery.
III. Core Specifications (Typical C-Series Models)
| Model | Feed Opening (mm) | Max. Feed Size (mm) | Discharge Setting Range (mm) | Capacity (t/h) | Motor Power (kW) | Total Weight (t) |
|---|---|---|---|---|---|---|
| C96 | 930×580 | ≤480 | 70–200 | 60–175 | 75–90 | ≈14 |
| C106 | 1060×700 | ≤580 | 70–200 | 160–360 | 110–132 | ≈16 |
| C116 | 1150×800 | ≤640 | 90–250 | 140–320 | 132 | ≈21 |
| C120 | 1200×870 | ≤700 | 70–200 | 160–500 | 160 | ≈33 |
Note: Capacities are rated based on limestone (density: 1.6 t/m³); for granite, multiply by 0.8–0.9; for iron ore, multiply by 0.7–0.8. Actual configuration (motor, voltage, hydraulic assistance, automation) depends on the specific selection scheme.
IV. Key Advantages of the European-Style C-Series Hydraulic Jaw Crusher
4.1 Deep-cavity inter-particle (lamination) crushing: Lower energy consumption per ton and reduced over-crushing
The deep V-shaped crushing cavity extends the material's crushing path and relies primarily on compression rather than impact. Consequently, energy consumption per ton is lower than that of impact-based equipment. In aggregate production lines, the proportion of fines decreases, easing the screening load; in mineral processing lines, sludge formation is reduced, leading to more stable separation performance.
4.2 Hydraulic wedge-style discharge setting adjustment: Specification changes take minutes
This is the C-series' major selling point compared to traditional jaw crushers: while shim-based adjustment requires 2–3 hours of downtime, hydraulic wedge adjustment takes only minutes and supports online fine-tuning. Based on four specification changes per month, this yields approximately 40–80 additional hours of effective production time annually, directly translating into increased output value.
4.3 Modular, Bolt-Together Frame: Fatigue-Resistant and Easy to Transport
The frame features a bolted, sectional design that eliminates residual welding stresses and the risk of weld cracking. For overseas projects, it allows for containerized shipping and on-site assembly without welding, thereby shortening the timeline from contract signing to full production.
4.4 Reversible High-Manganese Steel Jaw Plates: Controlled Wear Costs
The jaw plates and toggle plates are the primary wear components; made of high-manganese steel, the jaw plates are reversible. When processing moderately abrasive materials (such as limestone), the initial set of jaw plates lasts over 12 months, resulting in a per-ton wear cost significantly lower than that of comparable equipment.
4.5 Simple Structure and Interchangeable Parts: Low Maintenance Requirements
The system does not rely on complex hydraulic power units; routine maintenance focuses on jaw plate inspection and replacement, which can be handled by local maintenance teams. High interchangeability of spare parts across C-series models reduces both inventory pressure and the risk of downtime in remote mining areas.

V. Real-World Case Studies
Case 1: Granite Aggregate Line in Southeast Asia.
A quarry with an hourly output of 300–400 tons utilizes a single C106 unit for primary crushing, producing material ≤180mm that is fed directly into a cone crusher for secondary crushing. The entire line went from contract signing to production in approximately 8–10 weeks. Capacity utilization consistently exceeds 90%, with the finished 5–31.5mm aggregate supplied directly to a commercial concrete plant.
Case 2: Iron Ore Primary Crushing Station in South America.
Processing magnetite ore (feed size ≤650mm), a single C120 unit operates continuously at an actual throughput of approximately 420 t/h, producing material ≤180mm for secondary cone crushing. The unit operates over 7,800 hours annually; the initial set of jaw plates lasts about 14 months, and the per-ton wear cost is approximately 20% lower than the previous "dual-unit parallel" configuration.
Case 3: Mobile River Pebble Processing Line in Central Asia.
River pebbles are highly abrasive; clients utilize a "tracked mobile station + C96" solution for on-site processing. The discharge opening can be adjusted online to match aggregate specifications, allowing a single machine to switch between 20–40mm and 5–10mm finished products, thereby significantly reducing costs associated with site relocation and specification changes.

VII. FAQ
Q1: What is the difference between the European-style C-Series hydraulic jaw crusher and the standard PE jaw crusher?
Both operate on the jaw crushing principle, but differ in structure: The C-Series features a deep V-shaped crushing chamber and hydraulic wedge-based discharge opening adjustment, offering a higher crushing ratio and finer control over output particle size; discharge adjustments take minutes and can be performed online. The PE series primarily uses shim-based adjustment, emphasizing versatility and cost-effectiveness. For the same inlet size, the C-Series delivers more uniform output and greater flexibility in switching specifications, making it ideal for medium-to-large projects requiring high production line stability and multi-specification output.
Q2: How much downtime can be saved with hydraulic discharge adjustment compared to shim-based adjustment?
Shim-based adjustment requires shutting down the machine, cutting power, and disassembling/reassembling shim sets—a process taking 2–3 hours per instance. Hydraulic wedge adjustment takes only minutes and can be performed during operational intervals. Based on four specification changes per month, this yields approximately 40–80 additional hours of production time annually, directly translating to increased sales revenue.
Q3: How do I select a C-series model based on stone hardness and target production capacity?
Follow these three steps: First, determine the material's compressive strength (suitable for up to 320 MPa; apply a 0.8x multiplier to the capacity rating for granite, basalt, and iron ore). Second, select the model based on the target capacity: choose the C96 for the 60–175 t/h range, C106 for 160–360 t/h, C116 for 140–320 t/h, or C120 for 160–500 t/h. Finally, verify that the maximum feed size does not exceed the rated limit of the feed opening, and provide actual material samples to the manufacturer for specific calibration.
