Small Jaw Crusher
Small Jaw Crusher

The jaw crusher is the preferred equipment for primary crushing. The output of the small jaw crusher is very small. If you don't need to process a lot of materials, a small jaw crusher can meet the demand. Its hot-selling models are PE200X350, PE250X400, and PE400X600.

CI Series Impact Crusher
CI Series Impact Crusher

CI series impact crusher occupies an important position in the crushing industry with its high efficiency, wear resistance, flexible adjustment, and other characteristics.

Multi-cylinder Hydraulic Cone Crusher
Multi-cylinder Hydraulic Cone Crusher

The multi-cylinder hydraulic cone crusher is developed based on the spring cone crusher. Its basic structure is similar to that of the spring cone crusher, but it has better performance and a wider range of applications.

350-450 t/h Stone Crushing Plant introduction:

Core equipment selection and configuration

Coarse crushing equipment (jaw crusher)

    • Model recommendation: PE-1200×1500 or larger (feed size ≤1020mm, discharge opening adjustment range 150-300mm).
    • Power: 160- 200 kW, to meet the high crushing force requirements of hard rock (such as granite).
    • Wear-resistant parts: manganese steel movable jaw plate, life of about 6-12 months (depending on the hardness of the material).
 

Medium and fine crushing equipment (cone crusher/impact crusher)

    • Cone crusher (high hardness stone): CS220 cone crusher, processing capacity 130-530t/h, power 315kW, hydraulic adjustment of discharge opening (20-50mm).
    ​​​​• Impact crusher (medium and low hardness): PF1320, processing capacity 160-350t/h, suitable for limestone, etc., with better finished product particle shape.
    ​​​​• Key point: Cone crusher needs to be equipped with a hydraulic cavity cleaning system to prevent blockage.
 

​​Screening equipment (multi-layer vibrating screen)

    ​​• Model: 3YK3070 (3-layer screen, screen area 7㎡), processing capacity 400t/h, motor power 30kW×2.
    ​​​​• Screen configuration: upper layer 40mm (pre-screen), middle layer 20mm (medium material), lower layer 5mm (fine material).
    ​​​​• Anti-blocking design: rubber ball screen cleaning device or ultrasonic vibrating screen (applicable to high-humidity materials).

 FAQ about 350-450t/h stone crushing plant

 

1. How to choose a cone crusher and an impact crusher?

 
• Cone crusher: suitable for high-hardness stone (such as granite), good wear resistance, but the finished product particle shape is slightly poor.
• Impact crusher: suitable for medium and low hardness stone (such as limestone), good particle shape, but wears faster.
 

2. What process does the 350-450t/h crushing station generally adopt? ​

• Coarse crushing (jaw crusher) → Medium crushing (cone crusher/impact crusher) → Screening (vibrating screen) → Return material circulation
• Closed-circuit design can improve the yield rate (5-40mm aggregate accounts for ≥80%).
 

3. How to extend the life of the equipment?

​​​​• Regular maintenance: Lubrication system inspection (cone crusher main shaft bearing), screen replacement
​​​​• Optimize operation: Avoid overload operation and control feed particle size
 

4. What to do if the crushing station is blocked?

​​​​• Preventive measures: Install metal detectors and vibrating feeders to feed evenly
​​​​​​• Emergency treatment: Emergency shutdown, clean the crushing chamber (cone crusher can be hydraulically cleaned)
 

5. How to control dust and noise? ​​

​​​​​​​​• Dust: Pulse bag dust collector (30000m³/h air volume) + spray dust suppression
​​​​​​​​• Noise: Equipment shock-absorbing foundation (rubber pad) + soundproof cover (≤75dB)
