PEW Series European Jaw Crusher
The PEW Series European Jaw Crusher incorporates advanced European crushing technology with a V-type crushing chamber design that delivers higher crushing efficiency, more uniform product size, and reduced plate wear compared to traditional jaw crushers. The hydraulic discharge adjustment system allows quick, safe changes to output size, while the integrated motor base design reduces installation requirements and belt tensioning complexity. This crusher is designed for operators who demand higher performance, easier maintenance, and superior product quality from their primary crushing equipment.
Working Principle
European-style jaw crushing with V-type chamber geometry. The V-shaped crushing chamber provides more effective crushing at the top of the chamber where feed material enters, reducing the number of compression cycles needed. Hydraulic wedge adjustment replaces manual shimming for safe, rapid discharge setting changes. The integrated motor base eliminates separate motor foundation requirements.
The grinding process is precisely controlled by the integrated classification system, which separates qualified fine powder from coarse particles. Coarse particles fall back to the grinding chamber for regrinding, while fine powder is conveyed by airflow to the cyclone collector and then to the finished product silo. This closed-circuit design ensures consistent product quality and high grinding efficiency.
Key Features & Advantages
V-Type Crushing Chamber
Optimized chamber geometry provides higher crushing ratio and more uniform product size while reducing jaw plate wear by 20-30%.
Hydraulic Adjustment
Hydraulic wedge discharge adjustment allows safe, rapid changes to output size without tools, reducing downtime.
Integrated Motor Base
Motor mounted directly on the crusher frame eliminates separate foundation and simplifies belt tensioning.
Advanced Bearing Design
Larger, higher-grade spherical roller bearings with centralized lubrication provide extended bearing life and reduced maintenance.

Performance & Efficiency
The PEW Series European Jaw Crusher is designed for maximum grinding efficiency and energy savings. The optimized grinding chamber geometry, combined with high-precision classification, ensures that energy is used effectively for particle size reduction rather than wasted on over-grinding or heat generation. Compared to conventional milling systems, our equipment typically achieves 20-30% lower power consumption per ton of finished powder.
Key performance metrics include stable fineness control with deviation less than 5%, low noise levels below 75 dB at 1 meter distance, and dust emissions below 20 mg/m3 when equipped with our pulse bag filter system. These performance characteristics make our equipment suitable for even the most demanding industrial environments and stringent environmental regulations.
Installation & Commissioning
Proper installation is critical for optimal equipment performance and longevity. Our experienced engineers provide on-site installation and commissioning services, including equipment positioning, alignment, electrical connection, piping installation, and system integration. The typical installation timeline ranges from 15 to 45 days depending on equipment model and production line complexity.
During commissioning, we conduct comprehensive performance tests including no-load test, load test, and production trial runs. We verify all performance parameters meet design specifications, calibrate control systems, train your operators on proper operation and maintenance procedures, and deliver a complete commissioning report with all test data.
Frequently Asked Questions
The V-type chamber crushes more effectively at the top where material enters, reducing the number of compression cycles needed. This improves throughput by 15-20% and reduces plate wear by 20-30%.
A hydraulic cylinder adjusts the wedge position, changing the discharge opening size. This can be done during operation preparation without tools, taking seconds rather than the hours required for manual shimming.
