PE 900×1200 Jaw Crusher
In fields such as mining, building material processing, and infrastructure construction, the primary crushing stage serves as the "first gateway" of any crushing production line, directly determining the efficiency and throughput of subsequent processes. Thanks to its stable performance, massive processing capacity, and broad adaptability, the PE 900×1200 Jaw Crusher (commonly referred to in the industry as the "912 Jaw Crusher") has become the preferred choice for large-scale crushing projects, earning a reputation as the "throughput powerhouse" of the Jaw primary crushing sector. Today, we offer a comprehensive analysis of this flagship machine—covering everything from its core technical parameters, performance advantages, and application scenarios to practical operation and maintenance.

I. Core Parameters: Understanding the Machine's "Hardcore Capabilities"
As a large-scale jaw crusher, the PE 900×1200 features technical specifications precisely tailored to the demands of major projects. Key data points are as follows:
- Feed Opening Size: 900×1200 mm; maximum feed size ≤ 750 mm. This eliminates the need for pre-processing of large-sized raw materials, thereby saving significant time during the initial stages.
- Processing Capacity: 220–380 tons per hour (adjustable based on material hardness). This capacity is sufficient to meet the requirements for large-scale production at major aggregate plants and mining operations.
- Motor Power: 110–132 kW (8-pole). It delivers robust power while remaining energy-efficient, boasting a specific energy consumption rate that is 5%–10% lower than other equipment in its class.
- Other Key Specifications: Main shaft speed of 208–220 rpm; machine weight of 48–50 tons; and a discharge opening that is flexibly adjustable between 95–265 mm to seamlessly integrate with the requirements of downstream processes.

II. Core Advantages: Why It Stands Out as the "Preferred Equipment"
1. Deep Crushing Chamber with No Dead Zones: Smooth Feeding and Jam-Free Operation
The machine features an optimized deep-chamber design with no significant "dead zones." This ensures that materials flow smoothly into the chamber and undergo thorough compression and crushing, effectively preventing blockages, minimizing downtime for cleaning, and significantly enhancing production continuity.
2. Wear-Resistant, Durable, and Low Maintenance
The core wear parts—the jaw plates—are manufactured from high-manganese steel (ZGMn13) and undergo a water-toughening treatment. This extends their service life to 6–12 months—more than 30% longer than standard jaw plates. The machine body is constructed from cast steel components or thick welded steel plates, featuring a robust structure capable of withstanding heavy-load, continuous operation with a low failure rate.
3. Wide Adaptability and Powerful Crushing Capability
With a compressive strength capacity exceeding 300 MPa, the machine can process hard materials such as granite, basalt, and iron ore, as well as softer materials like limestone and construction waste. It is suitable for a wide range of applications—including mining, building materials, and environmental protection—and in practical use, it effectively increases the yield of finished products while reducing subsequent energy consumption.
4. Convenient Operation and Easy to Master
The control panel is intuitive and easy to understand, allowing operators to master the equipment after only brief training. The discharge opening can be adjusted via shims or a hydraulic mechanism, and wear parts are easy to dismantle and replace. Furthermore, maintenance costs are kept low, requiring only periodic grease injection at the four bearing lubrication points.

III. Typical Application Scenarios
As a "primary crusher," the PE 900×1200 is primarily utilized for the initial stage of coarse crushing and is well-suited for various sectors:
- Mining: Coarse crushing of metallic ores (gold, iron, copper) and non-metallic ores (granite, quartzite); typically paired with cone crushers and vibrating screens to form a complete production line.
- Building Materials & Aggregates: Processing aggregate raw materials such as limestone and river pebbles; the crushed output features uniform particle size, meeting the engineering requirements for highways, construction projects, and more.
- Infrastructure & Environmental Protection: Processing of engineering stone materials, recycling of construction waste, and tailings treatment; facilitates resource recycling and complies with green production standards.
IV. Key Points for Practical Operation and Maintenance
1. Operation Techniques
Before starting, conduct a comprehensive inspection of the lubrication system, fasteners, and the crushing chamber. Start the machine under a no-load condition; introduce feed material only after the machine is running stably, and feed the material evenly to avoid overloading. Ensure that the bearing temperature rise does not exceed 30°C (with a maximum absolute temperature limit of 70°C), and always clear out all remaining material from the crushing chamber before shutting down the machine.
2. Key Maintenance Points
Regularly lubricate the bearings (replacing the grease every 3–6 months); inspect wear parts for signs of wear and replace them promptly; tighten any loose fasteners; and check the electrical system's insulation and grounding to prevent malfunctions.
V. Summary
The PE 900×1200 Jaw Crusher strikes a perfect balance between high throughput, exceptional stability, and minimal wear, effectively meeting the core requirements of large-scale crushing projects. It serves to both boost production efficiency and keep operating costs in check. Whether for mining operations, aggregate production, or infrastructure and environmental projects, it stands as the premier choice for primary crushing—delivering an optimal blend of efficiency and cost-effectiveness. When selecting equipment, users should configure their production lines based on their specific material characteristics and capacity requirements to maximize the value derived from the machinery.
FAQ (Frequently Asked Questions)
1. What is the maximum material size that the PE 900×1200 Jaw Crusher can process?
The maximum feed size is ≤750 mm. This eliminates the need for pre-processing of large lumps, allowing them to be fed directly into the crusher and thereby saving on initial preparation time.
2. What is the processing capacity of this equipment, and what types of materials is it suitable for?
The processing capacity ranges from 220 to 380 tons per hour, varying specifically based on the hardness of the material being processed. It is capable of crushing hard materials with a compressive strength exceeding 300 MPa (such as granite and iron ore), and is also suitable for materials like limestone and construction waste. It is well-suited for applications across various sectors, including mining, building materials, and environmental protection.
3. What are the key considerations for routine maintenance?
• Regular Lubrication: Bearings should be re-greased every 3–6 months.
• Inspection of Wear Parts: Components subject to wear—such as jaw plates—must be replaced promptly (typically having a service life of 6–12 months).
• Operational Protocols: Start the machine under no-load conditions, feed material evenly, and avoid overloading; ensure that bearing temperatures do not exceed 70°C.
• Periodic Fastening: Inspect and tighten any loose bolts to ensure the stable and secure operation of the equipment.
