A PEX jaw crusher uses a reciprocating motion to crush materials between two jaws: one stationary and one moving. The stationary jaw is fixed, while the moving jaw oscillates, creating pressure that breaks down the material into smaller particles.

The key components include: - A frame for structural support. - Two massive jaws (one fixed and one movable). - Eccentric shafts to generate the crushing motion. - Springs or hydraulic systems for overload protection. - Drive units, such as motors or engines, to power the crusher.

PEX jaw crushers are designed to process hard and abrasive materials like rock, ore, gravel, sandstone, basalt, and construction waste. They are particularly suited for primary crushing in mining, quarrying, and construction industries.

The frequency of replacing jaw plates depends on factors like material hardness, feed size, and operating hours. Generally, jaw plates wear out gradually but can last several thousand hours depending on usage. Regular monitoring and inspection are recommended to ensure optimal performance.

The capacity of a PEX jaw crusher varies based on its model and specifications. Larger models typically handle higher capacities, while smaller ones are suitable for specific applications with lower throughput requirements. Capacity is often measured in tons per hour (t/h).
