PEC Series Alloy Crusher Research Report

1. PEC series alloy crusher

PEC series alloy crusher is classified as twin toggle plate pendulum jaw crusher. The structure shown in picture 1, mainly consists of frame, fixed jaw, connecting rod, toggle plate, adjustment set and transmission parts. When Crusher works, motor drives the eccentric shaft through triangle belt and pulley, which makes the connecting rod move up and down, leads the toggle plate drive the fixed jaw move back and forth, thus the material in crushing chamber was crushed and broken by the force of impact, press and crook.

3. Main features of the machine as follows:

1. High Strength

The machine structure is firm, its frame is welded of high-quality steel plate, and toggle plate, eccentric shaft and other parts are of high quality alloy steel. The machine’s strength is much higher than other general crushers, thus able to break various ferroalloys under 1500MPa.

2. The crushing chamber

General jaw crusher chamber’s has only one nip angle (usually 18 ° -22 °), theoretically and practically been proved that such a cavity is unreasonable and not suitable for crushing the high strength materials such as low carbon ferrochrome iron, and with low capacity and makes the tooth plate uneven. On contrary, the PEC series crusher cavity-shape is curved with variable nip angle, gradually decreases from the inlet, even the nip angle of main fracture zone is smaller than general jaw crusher. Its advantage is it is easy for discharge without block, and with high capacity, product size uniformity, suitable for processing high-strength alloy.

PEC series crusher tooth plate profile is arc-shaped, help to improve its life and material move down, causing fewer blockages, which is more efficient than the ladder tooth of the common jaw crusher.

As the professional manufacturer of complete sets of mining machinery, such as feed grizzly，China cement mills，Screw classifiers，jaw crushers, Henan Hongxing is always doing the best in products and service.
