PEX 250x1200 Fine Jaw Crusher - Secondary Stone Crusher
In stone production lines, the "recycled material" and "medium crushing" stages after the primary jaw crusher often determine the overall sand yield and energy consumption. The PEX 250×1200 is not a large, all-purpose machine; it's a "surgical knife" specifically designed for fine/secondary crushing.
Its ultra-wide 1200mm feed opening combined with a narrow 250mm cavity depth means it can maintain an extremely high crushing ratio even with large feed volumes, making it the cost-effective choice for high-hardness materials such as basalt and granite entering secondary crushing.
I. Core Technical Parameters (No False Labeling, Data Speaks for Itself)
| Technical Dimensions | Baichy PEX 250×1200 Standard Specifications | Production Significance |
| Feed Opening Size | 250 × 1200 mm | Extra-wide cavity, specifically designed for flat and long strip materials |
| Maximum Feed Size | ≤ 210 mm | Perfectly accommodates the products after primary crushing of PE series materials |
| Discharge Adjustment Range | 20 - 60 mm | Flexible control of finished product diameter, reducing circulating load |
| Processing Capacity | 16 - 52 t/h | Extremely efficient as a secondary crusher in medium-sized production lines |
| Eccentric Shaft Speed | 330 rpm | High-speed stroke, higher material crushing frequency within the cavity |
| Motor Power | 37 kW (Adaptable to 60Hz/High Altitude) | Balancing power output and energy-saving operation |
II. Why Choose Baichy PEX Series?
1. "Fast Crushing of Hard Materials" Power Geometry
The PEX 250×1200 adopts a higher frequency eccentric shaft design. Compared to ordinary jaw crushers, it has a shorter stroke but a higher frequency. This design increases the number of compressions the material undergoes within the crushing chamber by more than 15%, resulting in more uniform output particle size and a significant reduction in needle-like and flaky particles.
2. Mn18Cr2-Grade Wear Resistance Commitment
For highly abrasive conditions such as Philippine river rock or Mexican basalt, we standardize the use of Mn18Cr2 (ultra-high manganese) moving and fixed jaw plates. Through optimized heat treatment processes, their service life is increased by approximately 30% compared to similar products on the market (Mn13), effectively reducing downtime for replacement.
3. Shim-Type Discharge Adjustment: Simplicity Equals Reliability
Abandoning complex and easily damaged hydraulic adjustment systems, we insist on using classic shim-type adjustment. In dusty and harsh maintenance conditions in mining areas, a simpler structure means a lower failure rate; workers can complete the discharge port setting in just a few minutes.

III. Core Application Scenarios
• Basalt/Granite Sand Making Line: As a secondary crusher, it connects with the PE600×900 primary crusher to produce high-quality medium-grade crushed material.
• Construction Waste Recycling: Due to its wide feed inlet (1200mm), it can effectively handle long steel bars in concrete blocks without easily causing blockages.
• Mobile Station Module: Its compact body and weight of approximately 8 tons make it a core component of the medium-grade crushing module in tire/tracked mobile stations.
IV. Frequently Asked Questions (FAQ)
Q: Can the PEX 250×1200 crush stone directly?
A: Yes, but its design is for "fine crushing." If the stone particle size exceeds 210mm, it is recommended to first use a PE series crusher as the primary crusher; otherwise, it will increase power consumption and wear.
Q: Can the motor be customized?
A: Yes. We can supply Siemens or top-tier domestic brand motors with 220V/380V/440V and 60Hz frequency for markets such as the Philippines and Vietnam.
Q: What is the delivery time for vulnerable parts?
A: Baichy Heavy Industry maintains a year-round stock of 250x1200 jaw plates, eccentric shafts, and toggle plates, enabling delivery within 48 hours.
