I. Model Meaning

PE600×900:

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

• 600×900: The width × length of the feed opening is 600 mm × 900 mm, commonly known as "69 Jaw Crusher" in the industry, a medium-sized heavy-duty jaw crusher.

II. Main Technical Parameters (Standard Configuration)

• Feed Opening Size: 600×900 mm

• Maximum Feed Size: ≤500 mm

• Discharge Opening Adjustment Range: 60–160 mm (adjustable via shim plates or wedge adjustment)

• Production Capacity: 50–160 t/h (varies with discharge opening size and material hardness)

• Motor Power: 55 kW (6-pole, electric, customizable diesel option)

• Eccentric Shaft Speed: 220 r/min

• Equipment Weight: Approximately 28 t

• Overall Dimensions (Length × Width × Height): Approximately 2600×1900×2300 mm

III. Structural Composition

Main Components (heavy-duty, stable and durable design):

1. Frame: Integral cast steel or welded frame, thickened structure, strong bearing capacity, effectively reducing vibration and ensuring stable operation under heavy load.

2. Moving Jaw / Fixed Jaw: Jaw plates made of high manganese steel (Mn13Cr2), high wear resistance and impact resistance, replaceable and reversible, extending service life.

3. Eccentric Shaft: Made of high-strength alloy steel (40CrNiMo), precision machined and heat-treated, high toughness and wear resistance, driving the moving jaw to swing stably.

4. Toggle Plate (Thrust Plate): Transmits power to the moving jaw and serves as a safety part — it will break first when overloaded (e.g., hard foreign objects enter), protecting the main machine from damage.

5. Flywheel / Pulley: Large-diameter flywheel, stores sufficient rotational energy, balances the load, stabilizes the operation of the equipment, and reduces the impact of load fluctuations.

6. Adjustment Mechanism: Gasket-type or wedge-type adjustment, easy to operate, can quickly adjust the discharge opening size according to production needs, with high adjustment accuracy.

7. Lubrication System: Centralized forced lubrication system, equipped with oil pump and oil cooler, ensuring continuous and reliable lubrication of bearings and bushings, preventing overheating and wear.

IV. Working Principle

The motor drives the eccentric shaft to rotate through the V-belt → the moving jaw makes periodic reciprocating swings (crank-rocker mechanism) → when the moving jaw approaches the fixed jaw, materials are crushed by extrusion, splitting and bending; when the moving jaw moves away, crushed materials fall and are discharged by their own weight, realizing continuous cyclic crushing.

V. Performance Characteristics

1. Heavy-Duty Design, High Stability: Thickened frame and high-strength components, suitable for long-term continuous operation in large-scale mines and quarries, with low failure rate.

2. Large Crushing Ratio & High Output: Crushing ratio up to 6-10, production capacity 50-160t/h, efficient handling of large-size materials, meeting large-scale production needs.

3. Uniform Particle Shape, Good Quality: Optimized jaw plate curve design, resulting in uniform finished products, high cubic particle content, no excessive crushing, suitable for high-standard construction projects.

4. Easy Maintenance, Low Operating Cost: Simple structure, easy access to wearing parts (jaw plates, toggle plates), quick replacement, reducing downtime and operating costs.

5. Wide Adaptability: Adjustable discharge opening (60-160mm), suitable for crushing various hard materials, adaptable to different process requirements.

VI. Application Scope

• Materials: Ores and materials with compressive strength ≤ 320 MPa, such as granite, limestone, basalt, river pebbles, iron ore, copper ore, construction waste, quartz stone, etc.

• Scenarios: Large quarries, open-pit mines, concentrators, building materials factories, highway/railway large-scale construction projects, concrete mixing stations, solid waste treatment plants, etc.

• Production Line Position: Commonly used asprimary crushing equipment in medium and large-scale crushing production lines; can be paired with impact crushers, cone crushers, vibrating screens and conveyors to form a complete crushing and screening line.

VII. Installation and Use Points

1. Foundation: The concrete base must be designed according to the equipment weight and vibration parameters, level and firm, with reserved anchor bolt holes to ensure stability during high-load operation.

2. Feeding: Use a vibrating feeder for uniform feeding, avoid metal hard objects (steel bars, iron blocks) entering the crushing cavity, and strictly prohibit feeding materials exceeding the maximum feed size (≤500 mm).

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

4. Maintenance: Regularly check the wear of jaw plates, toggle plates and bearings; check the tightness of bolts and the oil level of the lubrication system; clean the equipment and replace wearing parts periodically to ensure long-term stable operation.

VIII. Common Configuration Reference

• Single Machine: 55 kW electric motor + high manganese steel jaw plate + gasket/wedge adjustment seat + centralized lubrication system

• Production Line: Vibrating Feeder → PE600×900 Jaw Crusher → Conveyor Belt → Impact Crusher/Cone Crusher → Vibrating Screen → Finished Product Silo
