4 Types of Stone Jaw Crushers: Features and How to Choose

A stone jaw crusher reduces large rocks into smaller pieces by compressing material between a fixed jaw plate and a moving jaw plate. It is widely used in quarries, mining operations, and aggregate production plants. PE, PEX, C Series, and CJ Series jaw crushers serve different crushing requirements. PE models are commonly used for primary crushing, while PEX models are often considered for smaller discharge sizes. C Series and CJ Series models are designed for demanding crushing applications, depending on their specifications.

When choosing a jaw crusher, consider the maximum feed size, required capacity, discharge setting, material properties, and compatibility with downstream equipment.

1. PE Series Jaw Crusher: For Primary Crushing

The PE Series jaw crusher is commonly used as primary crushing equipment in quarries and mining plants. It reduces large rocks to a suitable size for secondary crushing or further processing.

PE jaw crushers can process granite, basalt, limestone, and various ores when the selected model matches the material properties and operating requirements.

When should you choose a PE jaw crusher?

Choose a PE model when your plant needs to process relatively large raw material at the first crushing stage. Check the maximum feed size, required hourly capacity, discharge opening, and the feed requirements of the next processing stage.

For example, a granite quarry may use a PE jaw crusher to reduce blasted rock before sending the material to a secondary crusher and vibrating screen.

2. PEX Series Jaw Crusher: For Smaller Discharge Sizes

The PEX Series jaw crusher is often used for secondary crushing or applications requiring a smaller discharge size. It may be suitable when the incoming material has already been reduced to an appropriate size.

For example, a limestone plant may use a primary jaw crusher to reduce large rocks, followed by a PEX jaw crusher to produce smaller material for further screening or processing.

When should you choose a PEX jaw crusher?

Check the maximum feed size, discharge adjustment range, required capacity, and target product grading. A PEX model should only be selected when these requirements fall within its operating range.

Do not choose a PEX crusher simply because its purchase price is lower than that of a cone or impact crusher. Compare throughput, product shape, wear-part consumption, and total operating cost before deciding.

3. C Series Jaw Crusher: For High-Capacity Primary Crushing

The C Series jaw crusher is designed for high-capacity primary crushing in demanding mining and quarry applications. Baichy's product range includes models with maximum feed sizes of approximately 400–1,200 mm and stated processing capacities of 50–1,400 tonnes per hour, depending on the model.

Its design features include a deep crushing chamber, a non-welded frame structure, and adjustable discharge settings. These features support heavy-duty operation when the machine is correctly selected and maintained.

Typical applications include primary crushing of granite, basalt, iron ore, and other hard rock materials.

When should you choose a C Series jaw crusher?

Consider a C Series model when your project requires a large feed opening and high primary-crushing capacity. Confirm the exact model's maximum feed size, capacity, discharge setting, motor power, and installation requirements before purchasing.

4. CJ Series Jaw Crusher: For Mining, Quarrying, and Mobile Crushing

The CJ Series jaw crusher is designed for crushing applications in mining, quarrying, and cement production. Baichy's CJ Series features a deep, optimized crushing chamber, a non-welded modular frame, and an adjustment system intended to simplify operation and maintenance.

The range includes models with maximum feed sizes of approximately 480–780 mm and stated processing capacities of 60–500 tonnes per hour, depending on the model and operating conditions.

Its design can also make it suitable for mobile crushing plants, where equipment transport, installation, and relocation are important considerations.

When should you choose a CJ Series jaw crusher?

Consider a CJ model when its specifications match your feed material, production target, and installation conditions. It may be evaluated for a fixed production line or mobile crushing station.

For example, a mobile granite crushing plant may use a CJ jaw crusher for primary crushing before sending material to a secondary crusher and screening system. The final configuration depends on the required capacity and finished aggregate sizes.

These are general application guidelines. Always confirm the specifications and recommended applications of the exact model.

How to Choose the Right Stone Jaw Crusher

1. Check the Maximum Feed Size

Determine the largest rock entering the crusher, not just the average feed size. The crusher's allowable feed size must match the incoming material. Oversized rocks may cause blockages and reduce production efficiency.

2. Define the Required Capacity

Estimate the required production in tonnes per hour. Actual throughput depends on feed size distribution, rock properties, discharge setting, feeding consistency, and operating conditions. Ask the supplier to verify capacity for your specific application rather than relying only on the maximum catalogue figure.

3. Set the Required Discharge Size

The discharge setting affects product size and throughput. If your plant requires several aggregate sizes, check whether secondary crushing and screening equipment are needed to achieve the final grading.

4. Consider Rock Hardness and Abrasiveness

Granite and basalt can cause substantial wear because of their hardness and mineral composition. Discuss material hardness, abrasiveness, moisture, and feed characteristics with the supplier to determine suitable equipment and wear parts.

5. Compare Total Operating Cost

Consider more than the purchase price. Energy consumption, jaw plate replacement, maintenance labor, downtime, installation, and compatibility with downstream equipment all affect the cost per tonne.

Practical Jaw Crusher Selection Example

Consider a granite quarry producing aggregate for road construction. The raw material contains large rocks, and the plant needs a consistent feed for secondary crushing and screening.

The buyer first confirms the maximum feed size and required hourly production. PE, C Series, and CJ Series models can then be evaluated against these requirements. A PE model may suit a smaller or medium-scale primary-crushing configuration, while a C Series model may be worth considering when the project requires higher throughput and a larger feed opening. A CJ model may be suitable when its capacity and installation requirements fit the project.

The final configuration must also account for secondary crushing, screening, target aggregate sizes, and maintenance costs.

This is an illustrative selection example, not a verified customer installation. Actual equipment selection requires project-specific material and production data.

Common Mistakes When Selecting a Jaw Crusher

Choosing by price alone. A lower purchase price does not guarantee lower operating costs. Compare wear parts, energy use, maintenance, and expected production.

Ignoring maximum feed size. Oversized material can cause blockages and reduce efficiency. Confirm the machine's allowable feed size.

Confusing crushing stages. PE, C Series, and CJ Series models may be used for primary crushing depending on their specifications, while PEX models are often considered for smaller discharge requirements. Select equipment according to the actual process.

Relying only on catalogue capacity. Capacity depends on material properties, feed size, discharge setting, and operating conditions.

Overlooking downstream equipment. The crusher must work with the feeder, conveyors, secondary crusher, and screens. Poor equipment matching can restrict the entire plant.

Choose the Right Jaw Crusher for Your Project

The right stone jaw crusher depends on material properties, feed and discharge sizes, production capacity, and the complete crushing process. PE, PEX, C Series, and CJ Series jaw crushers serve different requirements, so compare verified model specifications instead of choosing by series name or purchase price alone.

Prepare your material details, production target, finished-product requirements, and installation conditions before requesting a quotation. This information helps Baichy Machinery evaluate suitable jaw crusher models and recommend a practical crushing plant configuration.
