What causes the impact crusher old pumping air

Impact crusher in the ore crushing and processing operations in the process of a common piece of crushing equipment, generally used for ore in the fine crushing and processing operations, Shenyang Mountain Friends here to talk to you about the use of impact crusher in the process of machine pumping phenomenon, leading to the impact crusher to appear the reason for this problem is what? I hope that you do not encounter this situation is not nervous, there are any problems can come to consult Shenyang Shanyou.

The main reason for the pumping phenomenon of the impact crusher is that the airflow inside the crushing chamber is not smooth, which generates a certain negative pressure and draws the surrounding air into the crushing chamber. The main reasons for this phenomenon are as follows:

Poor sealing of the crushing chamber

When the crushing chamber is not sealed properly, surrounding air can enter the crushing chamber through poorly sealed gaps. In addition, there may be damaged seals, improper installation and other reasons for poor airflow inside the crushing chamber.

Insufficient material in the crushing chamber

When the material inside the crushing chamber is insufficient, the material is prone to oscillate and form air currents, thus causing the phenomenon of air extraction. In this case, it can be solved by increasing the amount of material input or adjusting the operation status of the crusher.

Improper feeding method

Improper feeding method may also lead to air extraction in the crusher. For example, when the feeding pipe is not smooth or too long, the material inside the crushing chamber is easy to form an air flow, which will cause the pumping phenomenon.
