A jaw crusher is a strong machine that breaks big rocks into small pieces. You can think of a jaw crusher like a nutcracker or your own jaw. It uses two plates. One plate stays still and the other moves. The plates crush materials between them. This simple design makes jaw crushers important in many jobs. You will see jaw crushers in mining. They help get minerals out of rocks. In construction, they crush concrete, asphalt, and bricks. These machines also help with recycling and demolition. They turn waste into material you can use again. Many companies need jaw crushers, cone crusher parts, and other crusher accessories. These tools help their work go well.
Jaw crushers crush big rocks into small pieces. They use two plates. One plate stays still and the other moves. This helps crush things fast and well.There are two main types of jaw crushers. Single-toggle crushers are simple and work well with soft materials. Double-toggle crushers use more force for hard rocks.Jaw crushers are used in mining, construction, and recycling. They also help make aggregates. They save time and money. They help recycle old materials.ONA sells strong jaw crushers parts. Their experts help you pick, fix, and care for your machine. This makes your jaw crusher last longer.Jaw crushers are cheap to use and last a long time. They can do many jobs. They help you work faster and better with tough materials.
A jaw crusher helps break big rocks into smaller pieces. It uses two jaws to crush things. One jaw stays still. The other jaw moves back and forth. The moving jaw pushes the material against the fixed jaw. This crushes the material into smaller bits. There are different types of jaw crushers. They are called Blake, Dodge, and Universal. The difference is where the pivot point is. Blake jaw crushers can be single-toggle or double-toggle. Single-toggle crushers move in an oval shape. They work best with softer materials. Double-toggle crushers have a more complicated motion. They are better for hard and rough materials. All types use the same idea. They crush things by pressing them between two jaws.
A jaw crusher has many important parts. Each part helps the machine work. Here is a table that shows the main parts and what they do:
Component | Function |
|---|---|
Main Frame | Holds all the parts and takes the crushing force. |
Fixed Jaw Plate | Stays in place; grips and crushes material with strong steel. |
Movable Jaw Plate | Moves to crush material; attached to a pivot; made to last. |
Eccentric Shaft | Changes spinning motion to back-and-forth jaw movement. |
Pitman | Connects the shaft to the moving jaw; helps the jaw move; has smooth bearing points. |
Toggle Plates | Link pitman to frame; help lift and protect; break if overloaded. |
Flywheels | Store energy for smooth running; help the engine move. |
Setting Mechanism | Changes the space between plates to control size; uses shims or hydraulics. |
Each part works together to help the jaw crusher do its job.

ONA cares about quality and helping customers. That is why many people trust ONA for their crushing machines.
You may wonder how jaw crushers break big rocks. The jaw crusher working principle is easy to understand. You put material into the top of the machine. The movable jaw goes back and forth. It pushes against the fixed jaw. This makes pressure and sometimes friction. The material gets squeezed and breaks apart. The jaw crusher working principle uses force to crush hard things. You can change the gap between the jaws. This controls the size of the pieces that come out. This idea makes jaw crushers good for many jobs.
ONA builds every jaw crusher using this idea. Their engineers use special tools to check each part. ONA’s team looks at every detail. You get a machine that works well and lasts longer. The jaw crusher working principle helps you crush tough things with less work.
When you use a jaw crusher, crushing starts right away. The movable jaw pushes the material against the fixed jaw. The force breaks the material into smaller pieces. This keeps happening until the pieces are small enough to fall out.
Let’s look at the forces used in the crushing process:
Jaw Crusher Type | Mechanical Forces Involved | Description |
|---|---|---|
Single-toggle | Pressure and friction | The movable jaw moves in an oval path. It uses both pressure and friction to crush material. |
Double-toggle | Pressure only | This type uses only pressure. It is better for very hard materials and lasts longer. |
Single-toggle jaw crushers use pressure and friction. Double-toggle jaw crushers use only pressure. Both types use the same main idea, but the forces are a little different. ONA’s team can help you pick the right type for your job. They also have wear parts and cone crusher parts to keep your machines working.
ONA’s machines are special because of careful design. Each jaw crusher gets tested a lot. ONA uses special tools to check every part. You get a product that meets high standards and works well.
Think about how your jaw works when you eat food. Your lower jaw moves up and down. It crushes food against your upper jaw. A jaw crusher works in a similar way. The movable jaw is like your lower jaw. The fixed jaw is like your upper jaw. The material gets stuck between the jaws. It breaks apart as the movable jaw presses it.
Another way to think about it is a nutcracker. You put a nut between the two arms. When you squeeze the handles, the nut cracks open. Jaw crushers use this same idea to break rocks and other hard things.
ONA’s engineers make each jaw crusher to copy this action. They use strong materials and careful measurements. You get a machine that works like your jaw—strong, reliable, and efficient.
Tip: If you want to know how jaw crushers work in different jobs, ONA’s team can help you. They give expert advice and custom answers for your needs.
Let’s compare jaw crushers to other crushers:
Factor | Jaw Crusher | Cone Crusher |
|---|---|---|
Crushing Principle | Simple compression action | Complex crushing with wobbling mantle |
Feed Size | Handles bigger feed sizes (up to 1,500 mm) | Needs smaller feed sizes (up to 350 mm) |
Reduction Ratio | 4:1 to 9:1 | 6:1 to 8:1 |
Production Capacity | Higher (200-1,000 tons/hour) | Lower (100-750 tons/hour) |
Energy Consumption | Lower (1-2 kWh/ton) | Higher (2-4 kWh/ton) |
Crushing Stage | Used for primary crushing | Used for secondary and tertiary crushing |
Product Quality | Coarser, less even | Finer, more even and cubical |
Material Suitability | Hard, rough materials, not sensitive to moisture | Medium to hard materials, needs steady feed |
Maintenance | Simple design, fewer parts to replace | More complex, higher maintenance costs |
Jaw crushers work best for first crushing. They handle big pieces and use less energy. Cone crushers are better for finer, more even products. ONA has both jaw crusher and cone crusher parts, so your equipment stays in good shape.
ONA’s focus on quality means you get a jaw crusher that works well and lasts longer. Their machines help you save time and money, making your job easier.
Jaw crushers are used in many fields. You see them in mining, construction, making aggregates, and recycling. These machines help break tough materials. They make hard jobs easier. Let’s see where jaw crushers are used and how ONA helps.
Jaw crushers are the first machines used in mining and quarrying. They break big rocks and ores into smaller pieces. This makes it easier to process them later. In 2023, jaw crushers broke over 10.6 billion metric tons of rock. This shows how important they are for crushing ore and stone. Jaw crushers are trusted for the first step in ore plants. They handle hard and rough materials every day.
In construction and recycling, jaw crushers turn waste into useful stuff. You can use them to crush old buildings and concrete. Here is what jaw crushers do in these jobs:
Crush concrete and debris into small pieces to use again.
Take out metal, wood, and trash before crushing, often with magnets.
Sort clean concrete by size to make crushing easier.
Make recycled concrete aggregate (RCA) for new roads and buildings.
Save money and help the planet by recycling at the site or plant.
Jaw crushers make good recycled materials. You get strong RCA for new work. You also help the earth by keeping waste out of dumps.
Jaw crushers are the first step in making aggregates. They take big pieces, up to 1,500 mm, and crush hard rocks like granite and limestone. The crushed rock is usually rough and may need more crushing. Jaw crushers give even sizes, low wear, and low costs. Here is a table with some models and what they can do:
Model | Feeding Opening Size (mm) | Max Feed Size (mm) | Discharge Opening Size (mm) | Capacity (t/h) |
|---|---|---|---|---|
PE250×400 | 250×400 | 210 | 20-60 | 5-20 |
PE400×600 | 400×600 | 340 | 40-100 | 16-60 |
PE500×750 | 500×750 | 425 | 50-100 | 40-110 |
PE600×900 | 600×900 | 500 | 75-160 | 64-128 |
PE750×1060 | 750×1060 | 630 | 80-140 | 51-208 |

There are two main types of jaw crushers. These are single-toggle and double-toggle. Each type works best for certain jobs. Knowing the differences helps you pick the right one.
A single-toggle jaw crusher has one toggle plate. It also has an eccentric shaft at the top of the moving jaw. The moving jaw swings in a curve. It pushes material against the fixed jaw. This is like how a nutcracker works. The single-toggle design is simple. It has fewer parts. This makes it easy to fix and adjust. These crushers can take in big pieces. They are good for first crushing in mining and building. The jaw plates are made from strong steel. They last a long time. You can use single-toggle crushers for soft stones and hard rocks. They also work for concrete with rebar. Many people use them with screening plants to get the right size.
Tip: If you want a crusher that is easy to set up and fix, pick a single-toggle jaw crusher.
A double-toggle jaw crusher has two toggle plates. It also has a pivot point. The eccentric shaft is behind the moving jaw. This design makes the jaw move up and down. Double-toggle crushers make more crushing force. They are best for very hard and rough rocks. These include granite and iron ore. These machines are heavier and have more parts. They do not need fixing as often but are harder to service. Double-toggle crushers are used in big mining jobs. They give high power and last a long time.
You can see the main differences in this table:
Feature | Single Toggle Jaw Crusher | Double Toggle Jaw Crusher |
|---|---|---|
Toggle Mechanism | One toggle plate | Two toggle plates |
Jaw Motion | Moves in an oval shape | Moves straight up and down |
Crushing Force | Medium | High |
Best For | Softer to medium-hard materials | Very hard, rough rocks |
Maintenance | Cheaper, needs more often | Costs more, needs less often |
Capacity | 200–300 T/H | Up to 600 T/H |
