how to adjust the discharge opening of impact crusher

The discharge opening of impact crusher has always been one of the most important design parameters in the development of new crushers.The size of the discharge opening determines the maximum size of material that can be discharged from the crusher.It also determines the maximum size of material that can be fed to the crusher and the minimum size of material that can be discharged.In order to meet the different needs of users,the discharge opening of impact crusher can be adjusted.So,how to adjust the discharge opening?

What is the discharge opening of impact crusher

The discharge opening of the impact crusher is the distance between the impact plate and the rotor. When the crusher is working, the material is fed into the crushing chamber from the feeding port, and it is crushed by the impact of the rotor rotating at high speed. The material that has been crushed is discharged from the outlet at the bottom of the machine.

The size of the discharge opening can be adjusted by changing the distance between the impact plate and the rotor. If you want to reduce the discharge opening, you can move the impact plate closer to the rotor; if you want to increase it, you can move it away from the rotor. However, be careful not to make too drastic a change, as this could damage your crusher.

How to adjust the discharge opening of impact crusher

The discharge opening of an impact crusher is the space between the blow bar and the rotor. This space represents the crushing chamber size. When the blow bar strikes the material, it is crushed by impact. The opening at the bottom of the jaw determines how much material can flow through it. For example, a smaller discharge opening would be used for a softer rock, such as limestone, while a larger discharge opening would be used for a harder rock, such as granite.

To adjust the discharge opening of an impact crusher, simply loosen or tighten the tension rod that runs through the middle of the blow bars. This will allow you to move the blow bars closer together or further apart. Remember to always check for clearance before making any adjustments.

The benefits of adjusting the discharge opening

There are many benefits to adjusting the discharge opening of an impact crusher. By doing so, you can increase the productivity of the machine as well as improve its energy efficiency. Additionally, adjusting the discharge opening can help to protect the crushing chamber from damage and reduce wear and tear on the machine over time.

How to maintain the discharge opening

1. feeding the material into the impact crusher;

2. opening the discharge door;

3. using a wrench to turn the adjusting bolt in the proper direction (clockwise to widen the opening, counterclockwise to close it);

4. closing the discharge door.

The factors that affect the adjustment of discharge opening

There are many factors that affect the adjustment of discharge opening, such as material properties, crusher structure, etc. If the material is too hard or the feeding size is too large, it will not be broken and the discharge opening cannot be adjusted. The structure of impact crusher also affects the adjustment of discharge opening. If the rear counterattack frame is installed on the ground, it is easy to adjust the discharge opening; if it is installed on a higher level platform, it is not easy to adjust the discharge opening.

The methods of adjusting discharge opening

The impact crusher is widely used in the sand and stone production line for its perfect finished product size and good grain shape. However, we often find that the discharge opening of the impact crusher is too small, which will seriously affect the production efficiency. So, how to adjust the discharge opening of impact crusher?

There are two methods of adjusting the discharge opening: manual adjustment and hydraulic adjustment.

1. Manual adjustment:
The adjusting screws on both sides of the machine can be turned up or down to increase or decrease the size of the discharge opening. This method is simple and convenient, but it is not easy to achieve ideal results.

2. Hydraulic adjustment:
This method is more accurate and efficient than manual adjustment. The hydraulic station is used to provide high-pressure oil, which actuates a cylinder connected to the adjusting sleeve, so that the sleeve can move up or down to achieve the desired discharge opening size.

Conclusion

The discharge opening of an impact crusher is one of the most important aspects that need to be taken into consideration when operating this type of machinery. Improper adjustment of the discharge opening can result in serious safety hazards and can also lead to inefficient operation of the crusher. By following the steps outlined in this article, you can ensure that your impact crusher is operated safely and efficiently.
