Key Features
Deep V-Shaped Crushing Chamber
The unique chamber design minimizes dead zones, maximizing feeding efficiency and output. It ensures uniform particle size distribution and a high crushing ratio (up to 6:1), making it suitable for producing aggregates with consistent quality .
Durable Construction
Built with a heavy-duty welded steel frame and manganese steel jaw plates (Mn13Cr2 or Mn18Cr2), the crusher withstands high-impact forces and abrasive materials, ensuring long service life even in harsh environments .
Adjustable Discharge Opening
The discharge port can be easily adjusted between 20–80 mm using a wedge-style mechanism, allowing flexibility to meet different production requirements for various applications .
Energy-Efficient Operation
Equipped with a 15 kW electric motor (AC 380V/220V), the crusher delivers stable performance with low energy consumption. It also features a flywheel design to reduce vibration and optimize power distribution .
Low Maintenance
The simple structure and modular components facilitate easy inspection, maintenance, and replacement of wear parts like jaw plates and toggle plates, minimizing downtime .

Why Choose jaw Crusher 250x400?
Portability: Compact size allows easy installation in confined spaces or mobile crushing plants.
Versatility: Handles materials with compressive strengths up to 320 MPa, ensuring adaptability to diverse applications .
Cost-Effective: Low operating costs and high productivity make it a cost-efficient choice for small to medium-scale operations.
Reliability: Backed by a 1-year warranty and supported by a global network of suppliers for quick parts replacement .
Operation Principle
The jaw crusher 250x400 operates via a motor-driven eccentric shaft that drives the movable jaw plate to reciprocate against the fixed jaw plate. Material enters the chamber from the top, where it is crushed by compression and shear forces. The crushed material exits through the adjustable discharge opening at the bottom .
For seamless integration into your production line, the PE250x400 can be paired with conveyors, screens, and secondary crushers (e.g., cone or impact crushers) to achieve desired particle sizes.
FAQ
Q：Is the PE250x400 suitable for my small-scale mining project?
A：Yes, the PE250x400 is ideal for small to medium-scale operations with its 5–21 tons/hour capacity and compact design (1,300x1,090x1,270 mm). It works efficiently for primary crushing of hard rocks (up to 320 MPa compressive strength) in mining, quarrying, and construction recycling. For larger-scale projects, we can recommend compatible secondary crushers for a complete production line.
Q：Are there options for mobile installation, such as on a trailer?
A：Yes, its lightweight design (2,800 kg) and compact dimensions make it suitable for mobile setups. We can provide mounting brackets or skid bases for easy integration into mobile crushing plants. Consult our engineers for custom mobile installation solutions.
