Jaw crushers and gyratory crushers are both used for primary crushing, but they are designed for different production conditions.
A jaw crusher uses a moving jaw plate to crush material intermittently against a fixed jaw plate. A gyratory crusher uses a gyrating mantle and stationary concave to perform continuous crushing. In general, jaw crushers are more suitable for small-to-medium plants, mobile installations and projects with lower initial budgets. Gyratory crushers are usually selected for large mines requiring continuous operation and very high throughput.
The correct choice should not be based on capacity alone. Feed size, material properties, operating hours, installation conditions, maintenance resources and total cost per ton must also be considered.
Jaw Crusher vs. Gyratory Crusher: Quick Comparison
| Comparison factor | Jaw crusher | Gyratory crusher |
|---|---|---|
| Crushing action | Intermittent compression | Continuous compression |
| Main crushing parts | Fixed jaw and moving jaw | Mantle and concave |
| Typical application | Small-to-medium mines, quarries and recycling plants | Large mines and high-capacity crushing stations |
| Capacity range | Generally lower | Generally higher |
| Feed opening | Wide and rectangular | Large and annular |
| Installation | Simpler foundation and installation | Complex foundation and installation |
| Equipment height | Relatively low | Usually much taller |
| Initial investment | Lower | Higher |
| Maintenance | Generally easier | Requires more specialized maintenance |
| Mobile application | Commonly available | Rare |
| Cost per ton | Competitive at moderate capacity | Often lower at continuously high throughput |
The actual capacity and maximum feed size depend on the crusher model, material hardness, feed gradation, moisture content, bulk density, discharge setting and operating conditions.
What Is a Jaw Crusher?
A jaw crusher is a compression crusher consisting mainly of a fixed jaw plate and a moving jaw plate.
Material enters the crushing chamber through the upper feed opening. As the moving jaw approaches the fixed jaw, the material is compressed and fractured. When the moving jaw moves backward, the broken material travels downward and leaves through the discharge opening.
Because the crushing cycle is intermittent, a jaw crusher does not process material continuously throughout the entire eccentric rotation. However, its simple structure and reliable performance make it one of the most widely used primary crushers.
XINGAONAI offers both the PE Series Jaw Crusher and the PEV Series Jaw Crusher for different feed sizes, capacity requirements and installation conditions.

Mobile and semi-mobile crushing plants
For more information about the crushing process, see the jaw crusher working principle.
What Is a Gyratory Crusher?
A gyratory crusher is a large primary crusher that uses a mantle moving eccentrically inside a stationary concave.
Material is fed from the top of the crushing chamber. As the mantle gyrates, rock is continuously compressed between the mantle and concave. The crushed material gradually moves downward and is discharged from the bottom.
Unlike a jaw crusher, which has an intermittent crushing stroke, a gyratory crusher performs continuous crushing. This allows it to process a large and stable volume of material.
The X Series Gyratory Crusher is designed for large mining and high-capacity primary crushing applications.
Typical gyratory crusher applications
Gyratory crushers are commonly installed in:
Large open-pit mines
Underground mining operations
Iron ore and copper ore processing plants
Large limestone quarries
High-capacity aggregate plants
Permanent primary crushing stations
Projects requiring long, continuous operating periods
1. Difference in Crushing Principle
The most fundamental difference is the way the machines apply compressive force.
Jaw crusher crushing action
A jaw crusher uses reciprocating motion. The moving jaw approaches the fixed jaw during the crushing stroke and moves away during the discharge stroke.
This creates an intermittent crushing process:
Material enters the chamber.
The moving jaw compresses the material.
The rock fractures under pressure.
The moving jaw retreats.
Broken material moves downward.
The cycle repeats until the material passes through the discharge opening.
Gyratory crusher crushing action
A gyratory crusher uses a continuously moving mantle. As the mantle moves toward one side of the concave, it crushes the material. At the same time, material on the opposite side moves downward.
This produces continuous crushing around the chamber and allows the crusher to handle a steady, high-volume feed.
2. Capacity and Throughput
Gyratory crushers generally provide higher throughput than jaw crushers of a comparable feed opening.
Their continuous crushing action and large chamber allow them to process more material during each operating cycle. They are therefore commonly selected for mines where the primary crusher must support a large downstream processing plant.
Jaw crushers are usually more economical when the required capacity is moderate or when production is not completely continuous.
However, capacity values should not be compared using catalogue figures alone. Actual production depends on:
Crusher model and chamber design
Maximum feed size
Feed size distribution
Material compressive strength
Material abrasiveness
Moisture and clay content
Closed-side setting
Feeder performance
Downstream equipment capacity
In the overlapping capacity range, either crusher type may be technically possible. The final decision should be based on equipment utilization, installation cost, operating schedule and total cost per ton.
3. Feed Size and Feed Conditions
Both machines can accept large blasted rock, but their feed conditions differ.
Jaw crushers have a rectangular feed opening and can handle irregular, slab-shaped material relatively well. They are often preferred when feed size varies or when the material contains occasional oversized pieces.
Gyratory crushers have a large annular feed opening and are suited to continuous feeding from large trucks or mine haulage systems. They perform best when the feed is stable and evenly distributed around the crushing chamber.
Regardless of crusher type, oversize material, excessive fines, sticky clay and uneven feeding can reduce capacity and increase wear.
The maximum feed size should always be checked against the selected model rather than estimated only from the crusher category.
4. Product Size and Particle Shape
Both machines are primary crushers, so their main purpose is to reduce run-of-mine or blasted rock to a size suitable for secondary crushing.
Jaw crushers normally produce a relatively coarse product with a wider size distribution. The intermittent crushing action may also produce more elongated or flaky particles, depending on the material and discharge setting.
Gyratory crushers usually deliver a more consistent primary crushed product because crushing takes place continuously around the chamber.
Neither machine is normally selected to produce a finished aggregate shape directly. A cone crusher, impact crusher or other secondary crusher is generally required for further size reduction and particle-shape control.
5. Installation and Space Requirements
Installation conditions can strongly influence the final equipment choice.
Jaw crusher installation
Jaw crushers generally require:
A simpler concrete foundation
Less vertical installation height
A smaller overall project investment
Less complicated lifting equipment
Shorter installation and commissioning time
They can be used in stationary, semi-mobile and mobile plants, which makes them suitable for projects requiring relocation or flexible deployment.
Gyratory crusher installation
Gyratory crushers normally require:
A deep and heavy concrete foundation
Greater vertical clearance
Large supporting steel structures
Heavy lifting and maintenance equipment
More complex feed and discharge arrangements
Longer installation and commissioning periods
They are generally installed in permanent mining facilities where the crusher will operate for many years.
For underground projects, the size of the excavation, transportation route and assembly method must also be considered.
6. Initial Investment and Operating Cost
Jaw crushers generally have a lower purchase price and lower installation cost. Their simpler structure also reduces the cost and complexity of foundation construction, transportation and commissioning.
Gyratory crushers require a much larger initial investment. The crusher, foundation, structural support, lubrication system and maintenance facilities all contribute to higher capital expenditure.
However, purchase price does not determine the total economic result.
At very high and continuous production rates, a gyratory crusher may achieve a lower operating cost per ton because it can:
Process more material continuously
Reduce the number of required primary crushing units
Maintain stable downstream feeding
Operate efficiently in long-life mining projects
For small or medium projects, a jaw crusher is usually more economical. For a large mine with stable long-term production, the higher initial cost of a gyratory crusher may be justified.
7. Maintenance and Wear Parts
Jaw crusher maintenance
Typical jaw crusher maintenance includes:
Inspecting and replacing jaw plates
Checking the toggle plate
Lubricating bearings
Monitoring eccentric shaft condition
Adjusting the discharge opening
Tightening fasteners
Removing accumulated material
Its main wear parts are relatively accessible, and maintenance tasks can often be completed with standard workshop equipment.
For a more detailed structural explanation, see the guide to jaw crusher components and functions.
Gyratory crusher maintenance
Typical gyratory crusher maintenance includes:
Replacing the mantle and concaves
Inspecting the main shaft
Monitoring eccentric assembly wear
Maintaining the lubrication system
Checking hydraulic components
Measuring liner wear and chamber profile
Using heavy lifting equipment during liner replacement
Gyratory crusher maintenance is generally more specialized. Because the machine is often critical to the entire plant, maintenance planning and spare-parts availability are especially important.
8. Feeding and Operating Continuity
A jaw crusher can tolerate some variation in feed conditions, but it should still receive controlled and evenly distributed material. A vibrating feeder and grizzly are often installed before the crusher to remove undersized material and regulate the feed rate.
A gyratory crusher is designed for continuous operation and should be matched with a feed system capable of maintaining a stable material flow.
Irregular feeding can cause:
Uneven liner wear
Reduced capacity
Power fluctuations
Material bridging
Increased mechanical stress
Poor downstream production stability
If the primary crusher must operate continuously for long periods and a shutdown would interrupt the entire processing plant, reliability, redundancy and maintenance access should be included in the selection process.
9. Which Crusher Should You Choose?
Choose a jaw crusher when:
The project has a small or medium production target.
Initial investment needs to be controlled.
Installation space or foundation construction is limited.
A mobile or semi-mobile crushing plant is required.
Feed conditions are variable.
Maintenance needs to remain relatively simple.
The project requires flexible relocation or future expansion.
Choose a gyratory crusher when:
The operation requires very high and continuous throughput.
The crusher will serve a large, permanent mining plant.
Stable feed is available throughout the operating period.
The project has sufficient space and foundation conditions.
Lower long-term cost per ton is more important than initial price.
Professional maintenance personnel and lifting facilities are available.
The mine has a long operating life that can justify higher capital investment.
What about the overlapping capacity range?
Capacity ranges for jaw and gyratory crushers can overlap. Capacity alone should therefore not be used as an absolute selection boundary.
When both options appear suitable, compare:
Expected annual production
Daily operating hours
Equipment utilization rate
Feed-size distribution
Civil construction cost
Planned project life
Maintenance shutdown cost
Availability of spare parts
Energy consumption
Total cost per processed ton
A jaw crusher may remain the better choice at a relatively high rated capacity if the operation is intermittent. A gyratory crusher may be justified at a lower nominal capacity if the mine requires continuous production and has a long project life.
Information Required to Select a Primary Crusher
To recommend a suitable jaw crusher or gyratory crusher, the equipment supplier should receive the following information:
Material type
Maximum feed size
Feed-size distribution
Required capacity in TPH
Required discharge size
Material compressive strength
Abrasiveness
Moisture and clay content
Bulk density
Daily operating hours
Project operating life
Stationary, mobile or underground installation
Available installation space
Project location and elevation
Downstream crusher and processing equipment
Providing accurate operating data helps prevent undersizing, excessive investment and unstable plant performance.
Can a Jaw Crusher and Gyratory Crusher Be Used Together?
In most crushing plants, a jaw crusher and a gyratory crusher are alternative primary-crushing solutions rather than two consecutive crushing stages.
A typical jaw crusher circuit may be:
Jaw Crusher → Cone Crusher → Screening → Fine Crushing
A typical gyratory crusher circuit may be:
Gyratory Crusher → Cone Crusher → Screening → Fine Crushing
Using both machines in the same project is technically possible, particularly in a large operation with multiple crushing lines. However, installing a jaw crusher immediately after a gyratory crusher is generally unnecessary unless the plant has an unusual feed or process requirement.
Conclusion
The main difference between a jaw crusher and a gyratory crusher is not simply their appearance or rated capacity.
A jaw crusher offers lower initial investment, simpler installation, easier maintenance and greater flexibility. It is commonly selected for small-to-medium mines, quarries, recycling plants and mobile crushing applications.
A gyratory crusher provides continuous crushing, very high throughput and stable performance in large permanent mining operations. Although its purchase and installation costs are higher, it can achieve a competitive cost per ton when operating continuously at high capacity.
The final decision should consider feed characteristics, annual production, operating schedule, civil construction, maintenance resources and long-term project economics.
For a model recommendation, provide your material, maximum feed size, target capacity, required discharge size and project location. XINGAONAI can compare the appropriate jaw crusher and gyratory crusher options for your crushing plant.
