Impact Crusher How to Adjust Discharge Size

Impact crusher is a kind of crushing equipment often used in mining. It is usually applied to materials with medium hardness or less. It can be according to customer’s demand. Customised discharge size. The discharge size will directly affect the performance and effect of the impact crusher. So how to adjust the discharge size of the impact crusher?

The impact crusher’s discharge size is determined by: the spacing between the impact plate and the screen plate. If the spacing between the impact and screen plate is smaller. Then the finer the discharge size will be. On the contrary, the larger the distance, the larger the discharged material particle size. In addition, the spacing between the counterattack plate and the screen plate will also directly affect the processing capacity of its crushed materials. If the distance is small, it indicates that the crushing difficulty is large. To achieve the crushing effect of fine particle size.

The method of adjusting the discharge size of impact crusher:

1. Adjust the spacing between the impact plate and screen plate.
Adjusting the spacing is the most commonly used method to adjust the discharge size. Firstly, open the upper cover of the impact crusher. Then turn the screw rod under the screen plate to loosen. Then pull the upper screen plate lightly by hand. The distance between the upper and lower screen plate will become smaller. Thus, the granularity of the discharged material will be finer. If the upper screen plate is pulled upwards, the distance will be increased. The discharged material size is bigger.

2. Adjust the rotating speed of the impact crusher.
The rotating speed of the impact crusher will directly affect the size of the discharged material. If the rotating speed is too fast. If the rotating speed is too fast, the crushed material will pass through the speed faster. Discharge size will be coarser. If the rotating speed is slow. The passing speed of the crushed material between the impact plate and screen plate will be reduced. Discharge size will be finer.

3. Replacement of the screen plate hole pattern
The size of the holes in the screen plate is different. The size of the discharged material will be different. The larger the aperture of the sieve plate, the coarser the discharge size will be. The smaller the aperture, the finer the discharge size. If you want to adjust a certain size of the discharge size. Then you can replace the screen plate aperture size of the screen plate.
