Hydraulic Jaw Crusher


PEY series hydraulic protection stone jaw crusher with overload protection function, when unbreakable materials enters the crushing cavity, the equipment load rises sharply.

Meanwhile hydraulic protection device start to work to make the unbreakable materials unload immediately, thus avoiding impact to jaw crusher due to the sudden increase of load.

It solves the “steel blocking” problem in crushing materials effectively. PEY hydraulic protection jaw crusher is mostly used for the crushing of metallurgical steel slag.


Hydraulic protection jaw crusher is mainly used for steel slag processing plant since 1994, it is improved by Deya Machinery and exported to several countries.

Applicable materials: mainly used for steel slag primary crushing, secondary crushing

Features of Hydraulic Protection Jaw Crusher

Hydraulic protection jaw crusher with adjustable rated load, which can be used for crushing different compression strength materials selectively.

Hydraulic protection jaw crusher with reliable protection system, it discharges unbreakable materials automatically, which solves the “steel blocking” problem in steel slag crushing plant.

Automatically recovered after the discharge of unbreakable steel, it realizes continuous production without any stop, refer attached testing video of hydraulic jaw crusher in deya machinery workshop.

With support of the hydraulic station, the single hydraulic cylinder can adjust jaw crusher discharge opening, meanwhile it can discharge unbreakable material, which will not cause the unsynchronized phenomenon, it protects moving jaw during working.

The PEY series jaw crusher with hydraulic station and PLC automatic control system

The PEY series hydraulic jaw crusher is equipped position sensor, it can effectively display the discharge opening size.

Featured products

  • Impact bars

    The impact bars must be chosen according to the material type, abrasion, foreign elements and size at the feeding and the required product, so that best properties of different metallic alternatives may be used.

  • Mill liners

    Ball Mill liners are a major cost in mill operation, and efforts to prolong liner life are constantly being made. There are many types of wear-resistant alloys used for ball-mill linings, the more abrasion-resistant alloys containing large amounts of chromium, molybdenum, and nickel being the most expensive.

  • Mantle & bowl liners

    Mantle, covers the head of the crusher to protect it from wear, typical material ZGMn18Cr2 Bowl Liner, secured inside of the bowl to protect it from wear, typical material ZGMn18Cr2

  • Jaw plates

    Austenitic manganese steel is the industry standard material for jaw crusher liners. Due to its ability to work-harden during operation, it has proven to be versatile, and works well in a majority of applications. Typical material ZGMn13Cr2 and ZGMn18Cr2.
