PE600x900 Jaw Crusher
The PE600x900 Jaw Crusher (commonly referred to as the "69 Jaw Crusher") is the most widely utilized piece of medium-to-primary crushing equipment in sand and aggregate production lines. It features a feed opening size of 600x900mm, handles a maximum feed particle size of up to 500mm, and typically offers a production capacity ranging from 50 to 180 tons per hour.
Depending on the specific requirements of the production line—such as the type of stone crushing involved, the need for artificial sand production, or the hardness of the raw materials—the PE600x900 Jaw Crusher is typically paired with the following equipment:

1. Feeding Equipment (Front-end Integration)
To ensure the jaw crusher operates uniformly and continuously, as well as to facilitate the preliminary screening of fine silt, it is typically necessary to install a vibrating feeder.
Vibrating Feeder
Recommended Models: ZSW-380×95 or GZD-960×3800.
Function: To smoothly and steadily feed raw ore into the jaw crusher, thereby preventing material blockages.
2. Secondary Crushing Equipment (Mid-stream Integration)
The material discharged from the jaw crusher typically ranges in size from approximately 65mm to 160mm, necessitating a secondary crushing stage.
The choice of equipment for this stage depends on the hardness of the material:
For Medium-to-Soft Materials (e.g., Limestone, Bluestone):
PF Impact Crusher
Recommended Equipment: PF-1210 or PF-1214 Impact Crusher.
Advantages: Produces finished products with excellent particle shape (characterized by multiple angular facets and minimal needle-like or flaky particles) and involves relatively lower investment costs.
For High-Hardness Materials (e.g., Granite, Basalt, River Pebbles):
Spring Cone Crusher
Recommended Equipment: PYZ-1200 (or 1750) Cone Crusher, or Single-Cylinder/Multi-Cylinder Hydraulic Cone Crusher.
Advantages: Features a long service life for wear parts, exerts powerful crushing force, and is highly suitable for processing hard, brittle materials.
3. Screening and Conveying Equipment (Auxiliary Integration)
Vibrating Screen
Vibrating Screen: Responsible for classifying the crushed materials according to their particle size. Recommended Models: 3YK1854 or 2YK1848 Circular Vibrating Screen (select the number of decks based on the required finished product specifications).
Belt Conveyors: Used to facilitate material transfer between various pieces of equipment.
Recommended Specifications: B650 or B800 belt width.
4. Sand Making Equipment (Optional Addition)
If the production line is required to produce construction sand (0–5 mm), a sand making machine must be added following the secondary crushing stage.
Recommended Equipment: VSI-7611 or VSI-8518 Vertical Shaft Impact (VSI) Crusher.
5. Reference Configurations for Typical Production Lines (Approx. 100–150 tons/hour)
Scheme A (Standard Stone Crushing Line): Vibrating Feeder + PE600x900 Jaw Crusher + PF1214 Impact Crusher + 3YK1854 Vibrating Screen + Belt Conveyors.
Scheme B (High-Hardness Crushing Line): Vibrating Feeder + PE600x900 Jaw Crusher + PYZ1200 Cone Crusher + 2YK1848 Vibrating Screen + Belt Conveyors.
Recommendation: When making your final equipment selection, please take into account your specific material hardness, finished product size requirements, and production capacity targets. For a more precise and tailored solution, please provide the specific name or type of material you intend to crush.
Working Principle of the PE600x900 Jaw Crusher
PE600x900 Jaw Crusher Structural Diagram
The working principle of the PE600x900 Jaw Crusher can be summarized as a "toggle-action compression" mechanism. Its crushing action mimics the process of an animal chewing food, achieving material reduction through the relative motion of two jaw plates.
The detailed breakdown of the working steps is as follows:
1. Core Power Transmission
• Motor Drive: An electric motor drives a pulley, causing the eccentric shaft to rotate.
• Eccentric Motion: The rotation of the eccentric shaft causes the "moving jaw"—which is suspended from it—to execute a complex, reciprocating swinging motion.
2. Action within the Crushing Chamber (The "V"-shaped Space)
The crushing chamber consists of a fixed jaw plate and a movable jaw plate, forming a "V"-shaped space that is wider at the top and narrower at the bottom.
• Squeezing Phase (Approaching): When the eccentric shaft rotates to a specific angle, the movable jaw moves closer to the fixed jaw plate. During this moment, the stones that have fallen into the crushing chamber are subjected to squeezing, splitting, and fracturing forces from both jaw plates; their volume is reduced from large to small, thereby achieving the objective of crushing.
• Discharge Phase (Retreating): As the eccentric shaft continues to rotate, the movable jaw moves away from the fixed jaw plate under the action of tension rods and springs. At this point, stones that have already been crushed to the required particle size are discharged through the bottom discharge opening under the influence of gravity.
3. Characteristics of Compound Pendulum Motion (Unique to the PE Series)
The PE600x900 model belongs to the category of compound pendulum jaw crushers:
• The movable jaw executes not only a reciprocating motion in the horizontal direction but also a vertical motion in the up-and-down direction.
• Advantages: This specific motion trajectory facilitates the forced downward discharge of material, thereby enhancing crushing efficiency. Simultaneously, the material undergoes a more intense "kneading" action within the chamber, resulting in a higher crushing ratio.
4. Key Technical Details
• Deep-Chamber Crushing: This model features an optimized deep crushing chamber (free of dead zones), capable of accepting stones with a maximum size of 500mm while minimizing the risk of material clogging.
• Discharge Opening Adjustment: By adjusting the mechanism located at the rear of the movable jaw (typically utilizing shims or wedges), the size of the discharge opening (ranging from 65mm to 160mm) can be altered, thereby allowing for precise control over the particle size of the finished product.

Frequently Asked Questions (FAQ)
Q1: What is the actual output capacity of the PE600x900 jaw crusher? What are the feeding requirements?
A: The standard production capacity of the PE600x900 jaw crusher (commonly referred to as the "69 Jaw Crusher") ranges from 50 to 180 tons per hour, depending specifically on the hardness of the material being processed and the adjusted size of the discharge opening. Its feed opening dimensions are 600mm x 900mm, and the maximum permissible feed particle size is 500mm. We recommend equipping the unit with a ZSW-380×95 vibrating feeder to ensure a steady feed rate and maximize production capacity.
Q2: For the PE600x900 jaw crusher, how should one select the appropriate secondary crushing equipment?
A: The selection process primarily depends on the hardness of the material:
Medium-to-Soft Materials (e.g., limestone, bluestone): We recommend pairing it with a PF-1214 Impact Crusher. This combination produces finished products with excellent, cubical particle shapes, while keeping investment costs moderate.
High-Hardness Materials (e.g., river pebbles, granite): We recommend pairing it with a PYZ-1200 Cone Crusher. Cone crushers feature long-lasting wear parts, which effectively helps reduce the maintenance costs typically associated with processing high-hardness materials.
Q3: What size motor is typically equipped with the PE600x900 jaw crusher? What precautions should be taken during installation?
A: This crusher model is typically equipped with a 6-pole motor with a power output of 55 kW. During installation, ensure that the concrete foundation is stable and level, and leave sufficient clearance for maintenance access. The drive belts should be tensioned to an appropriate degree, and the protective guards for both the flywheel and the grooved pulley must be securely installed. Prior to commencing full-scale production, a no-load test run of 2 to 4 hours is required.
