Setting and Adjustment of Operating Parameters of PE500×750 Jaw Crusher

The PE500x750 jaw crusher is a commonly used machine for crushing large rocks and ores in various industries. Here are some steps for setting and adjusting the operating parameters of the PE500x750 jaw crusher:

1. Adjust the discharge opening: The discharge opening is the gap between the fixed jaw plate and the movable jaw plate. To adjust the discharge opening, first loosen the tension rod nut, then use a hydraulic jack to open the wedge-shaped adjustment device, and then adjust the gap to the desired size. Finally, tighten the tension rod nut to lock the adjustment device in place.

2. Adjust the toggle plate: The toggle plate is located between the pitman and the frame, and it provides support for the lower part of the moving jaw. If the toggle plate is not adjusted properly, it can cause excessive wear on the machine. To adjust the toggle plate, first turn off the power to the machine, then remove the cover plate from the front of the machine, and finally adjust the position of the toggle plate as needed.

3. Adjust the eccentric shaft: The eccentric shaft is responsible for driving the flywheel and the connecting rod of the machine. To adjust the eccentric shaft, first turn off the power to the machine, then remove the cover plate from the front of the machine, and finally adjust the position of the eccentric shaft as needed.

Here is a table detailing some technical specifications of the PE500×750 jaw crusher:

| Model | Feed Opening Size (mm) | Max. Feeding Size (mm) | Adjustable Rang of Discharge Opening (mm) | Capacity (t/h) | Motor Power (kw) |

|-------|------------------------|-------------------------|-----------------------------------------------|---------------|-----------------|

| PE500×750 | 500×750 | 420 | 50-100 | 40-110 | 55 |

In summary, setting and adjusting the operating parameters of a PE500×750 jaw crusher involves adjusting the discharge opening, toggle plate, and eccentric shaft. By properly managing these parameters, operators can optimize the crusher's performance and ensure efficient operation in a variety of applications.
