PEY series hydraulic jaw crusher is a kind of compound pendulum type crusher with overload protective function. When crush the unbroken material, the load of machine will increase suddenly, the machine can automatic load-off instantly though hydraulic protection, therefore it avoids to impact the body of machine because of the sudden increasing load. It can be safely used in crushing work with material mixed extremely hard foreign material.

The machine consists of three major parts: compound pendulum type jaw crusher, hydraulic protection device and electric control cabinet.

Working principle:

After the bulk material enters the crushing cavity (composed of fixed tooth plate, swing tooth plate and side plate) from upper end (feed opening), the material will be discharged from discharging opening after being masticated by movable jaw plate.

The masticate function of movable jaw plate is produced by eccentric shaft which is driven by transmission part. Acting as crank of four bar mechanism, eccentric shaft drives the movable jaw plate which acts as connecting rods, and then drives the toggle plate which act as rocker to swing, movable jaw plate makes complicated swing movement which is good for crushing and discharging under the constraint of both ends.
