PE series jaw crusher

Jaw crusher is a crushing machine that is researched and developed very early. With simple and solid structure, reliable work, easy maintenance and repair and low production and construction fees, it has long been widely used for the coarse, medium and fine crushing of various kinds of ores and rocks whose compression strength is 147~245MPa in many industrial departments such as metallurgy, chemistry, building material, power plant and transportation. In recent years, to satisfy the requirement of crushing micro-carbon ferro chrome with high strength and high hardness in the industrial departments of metallurgy, mine and building, our company has specially researched and manufactured powerful jaw crusher.

Jaw crusher is mainly used for the medium-granularity crushing of all kinds of ores and large materials in mine, metallurgy, building material, highway, railway, water conservancy and chemistry. The maximum compression strength of the materials to be crushed is 320MPa.

1. It adopts world-level manufacturing technology and high-end manufacturing materials.

2. More advanced movable jaw assembly makes it more durable. The movable jaw assembly uses high-quality steel casting and drives through two large-sized cast steel flywheels. In addition, the heavy eccentric shaft also adopts forging stock which makes JC series jaw crusher have extraordinary reliability.

3. The bearing pedestal adopts unitary cast steel structure. The unitary cast steel bearing pedestal can ensure comprehensive fitting with the crusher rack, and at the same time, greatly increase the radial strength of the bearing pedestal, whereas split type bearing pedestal does not have these advantages.

4. By using finite element analysis technology, the jaw crusher has higher strength.

5. The crushing chamber adopts symmetrical V-shaped structure, so that the actual width of the feeding mouth is in line with the nominal width of the feeding mouth.

6. The adjustment of the discharging mouth is quicker and more convenient. European type JC series jaw crusher is equipped with wedge discharging mouth adjustment device, so that the adjustment of the discharging mouth is simpler, safer and quicker than that of traditional gasket adjustment.

7. The selected bearing has bigger specifications and higher carrying capacity. All the JC series jaw crushers are equipped with eccentric shaft bearing bigger and more durable than the crushers with the same specifications, and the higher carrying capacity and effective labyrinth sealing of this bearing greatly extends its service life.

8. It adopts the latest tooth back plate which increases the effective length of the jaw plate and the output of jaw crusher.

The working manner of this series crushing machine is dynamic extrusion type, and its working principle goes like this: the electro motor drives the belt and belt wheel to make the movable jaw to move up and down through the eccentric shaft, and then movable jaw goes up, the angle between the toggle pate and the movable jaw is bigger, thus pushing the movable jaw to get close to the fixed jaw, and at the same time, the materials are crushed or smashed, thus reaching the goal of crushing; when the movable jaw goes down, the angle between the toggle pate and the movable jaw is smaller, under the effect of the draw bar and the spring, the movable jaw moves always from the fixed jaw, and then the crushed materials will be discharged out from the lower mouth of the crushing chamber. With the continuous rotation of the electro motor, the movable jaw of the crusher will do periodic motion to crush and discharge the materials, thus realizing mass production.
