Inquiry:
The second impact is large, and the power consumption of broken rocks is low. The weight of the piston and the tadpole is close, and there are excellent dynamic transmission. In terms of structural design, modern theory is adopted, so that the stress wave duration, low stress amplitude, and long piston life.
