The impact crusher is the second crushing equipment of the gravel production line. It is often used to process soft materials. Because the finished product has a good particle shape and uniform particles, it is welcomed by everyone. However, in actual production, customers often come to ask: What is the reason for too many counterattacks? The following is Jiaozuo Zhongxin to answer your questions.     1. The adjustment device is damaged
     The impact crusher adjustment device is the key to adjusting the size of the discharge port, so if the impact crusher returns too much material, it should be considered whether it is caused by the damage of the adjustment device.
     2. Plate hammer wear
     The impact crusher is suitable for processing softer materials, although this does not mean that the impact crusher cannot handle harder materials, but the hammer head is easy to wear when processing harder materials, so it is recommended that the impact crusher should be used to process softer materials; The impact crusher is regularly inspected and maintained, and the internal hammer head can be replaced. Only in this way can the efficiency of the production line be guaranteed.
