When choosing a jaw crusher and an impact crusher, you need to consider many factors, including material characteristics, production requirements, equipment performance, maintenance costs, etc.

Material Characteristics

• Jaw crusher:

Suitable for coarse and medium crushing of various materials with compressive strength below 320MPa.

Can handle larger materials, and the feed size range is usually 125-1020mm.

• Impact crusher:

Suitable for coarse, medium and fine crushing of various soft and medium hard ores.

Impact crushing machine has a wider adaptability to material hardness, but may wear faster when handling high hardness materials.

Production Requirements

• Output:

The output of jaw crusher is wide, ranging from 1 to 1000 tons per hour, depending on the equipment model and specifications.

The output of impact crusher can also reach 30 to 800 tons per hour, but it is usually slightly lower than that of jaw crusher of the same specifications.

• Finished product particle size:

The finished sand and gravel particles processed by jaw crusher are uniform, but may not be enough to meet the particle size requirements of some infrastructure sand.

The impact crusher has both shaping effects, and the fine material grading of the processed sand and gravel is reasonable, with less needle content, and can be used directly.

Equipment Performance

• Working principle:

The jaw crusher crushes materials through multiple forces such as squeezing, rubbing, and grinding of the movable and static jaws.

The impact crusher crushes materials through the impact plate driven by the motor to generate an extrusion force.

• Structure and maintenance:

The jaw crusher has a simple structure, is sturdy, works reliably, and is easy to maintain and overhaul.

The impact crusher has a unique structural design, but the wear rate of vulnerable parts (such as the hammer head) is high, and the maintenance cost may be high.

Maintenance Cost

• Jaw crusher: Due to its simple and sturdy structure, maintenance and overhaul are relatively easy and the cost is low.

• Impact crusher: The wear rate of wearing parts is high, and more frequent replacement and maintenance may be required, which is relatively costly.

Suggestions

• If the material is large and hard, it is recommended to choose a jaw crusher for coarse crushing.

• If there are strict requirements on the particle size of the finished product and the material hardness is moderate or low, you can choose an impact crusher for fine crushing and shaping.

• In practical applications, jaw crushers and impact crushers can also be used together to fully utilize the advantages of both.

In short, the choice of jaw crusher or impact crusher depends on factors such as specific material characteristics, production requirements, equipment performance and maintenance costs. Please contact us for more product information and choose the equipment that better suits your production needs.
