DPX(hammer) single segment crushing machine commonly used in(maximum compression strength 150Mpa) materials such as limestone.marlite. sandstone. Shale, plaster,coal and so on.It crushes big ore into required small granularity for one time, ,thereby displaces traditional twice or more crushing,to simplify process flow, reduce investment production cost.It has a big crushing tune and feeding hole which is suitable for big stone to letin smoothly. Rotor with spicial structure can break material along with width of whole machine,so crushing rate is higher than the others. Perforated strainer improves passing condition,it is not easy to close perture of Perforated strainer when breaks material with clay.Its structure is very firm ,and also there has iron-discharge gate to stop iron parts getting into the machine ,and protect main frame.
