I. Model Meaning

PE400×600:

• PE: Abbreviation of Jaw Crusher, the general code for jaw crusher series.

• 400×600: The width × length of the feed opening is 400 mm × 600 mm, commonly known as "46 Jaw Crusher" in the industry.

II. Main Technical Parameters (Standard Configuration)

• Feed Opening Size: 400×600 mm

• Maximum Feed Size: ≤340 mm

• Discharge Opening Adjustment Range:40–100 mm

• Production Capacity: 16–64 t/h (varies with discharge opening size and material hardness)

• Motor Power: 30 kW (6-pole)

• Eccentric Shaft Speed: 270–275 r/min

• Equipment Weight: Approximately6.5–7 t

• Overall Dimensions (Length × Width × Height): Approximately 1700×1700×1650 mm

III. Structural Composition

Main Components:

1. Frame: Integral cast steel frame, featuring high strength and strong vibration resistance, which can withstand the impact force during the crushing process.

2. Moving Jaw / Fixed Jaw: The jaw plates are made of high manganese steel, which has excellent wear resistance and can be turned over for reuse, extending the service life.

3. Eccentric Shaft: Drives the moving jaw to swing back and forth, and is strengthened by heat treatment to improve toughness and wear resistance.

4. Toggle Plate (Thrust Plate): Transmits power to the moving jaw and serves as a safety part — it will break first when overloaded to protect the main machine from damage.

5. Flywheel / Pulley: Stores rotational energy, stabilizes the operation of the equipment, and reduces the impact of load fluctuations.

6. Adjustment Mechanism: Gasket-type adjustment, which is easy to operate and can quickly adjust the size of the discharge opening according to production needs.

7. Lubrication System: Centralized lubrication design, which ensures the reliable operation of bearings and bushings, reduces friction and wear, and extends the service life of components.

IV. Working Principle

The motor drives the eccentric shaft to rotate through the V-belt → the moving jaw makes periodic reciprocating swings → when the moving jaw approaches the fixed jaw, the material is crushed by extrusion and splitting; when the moving jaw moves away from the fixed jaw, the crushed material falls and is discharged by its own weight, realizing continuous cyclic crushing.

V. Performance Characteristics

1. Deep Cavity Without Dead Zone: Strong feeding capacity, high output, and not easy to block materials, ensuring continuous and stable production.

2. Large Crushing Ratio & Good Particle Shape: The discharged material is uniform, with high content of cubic particles, which meets the requirements of subsequent processing and application.

3. Simple and Reliable Structure: Cast steel frame and high manganese steel jaw plates ensure low failure rate, simple maintenance, and easy replacement of wearing parts.

4. Energy Saving & Low Noise: Single machine saves 15%–30% energy compared with traditional models, with low operating noise and less dust, complying with environmental protection requirements.

5. Wide Adjustment Range of Discharge: The discharge opening can be adjusted between 40–100 mm, which can adapt to different process requirements and meet the needs of various application scenarios.

VI. Application Scope

• Materials: Ores with compressive strength ≤ 300 MPa, such as granite, limestone, basalt, river pebbles, iron ore, construction waste, etc.

• Scenarios: Small sand and gravel plants, primary crushing in mines, building materials industry, highway/railway subgrade construction, concrete mixing stations, solid waste treatment, etc.

• Production Line Position: Commonly used as the first stage of primary crushing, and then matched with impact crusher/cone crusher for medium and fine crushing to obtain higher-quality finished products.

VII. Installation and Use Points

1. Foundation: The concrete base must be level and firm, with reserved anchor bolt holes to ensure the stability of the equipment during operation.

2. Feeding: Feed materials evenly, avoid metal hard objects entering the crushing cavity, and strictly prohibit feeding materials exceeding the maximum feed size.

3. Startup Sequence: Start the machine with no load first → feed materials after normal operation; when shutting down, stop feeding first → shut down after the materials in the cavity are completely emptied.

4. Maintenance: Regularly check the wear of jaw plates, the tightness of bolts, and the bearing temperature (≤70℃); supplement lubricating grease in a timely manner to ensure the normal operation of the equipment.

VIII. Common Configuration Reference

• Single Machine: 30 kW motor + standard jaw plate + manual adjustment seat

• Production Line: Vibrating Feeder → PE400×600 Jaw Crusher → Conveyor Belt → Impact Crusher/Cone Crusher → Vibrating Screen
