The advantages of silent crushing hammer
Reduce noise
Protect the environment
Strong and powerful "hydraulic+nitrogen"impact system
The most important characteristics of the breaking hammer are the striking frequency and energy. Each model of DOPRO crushers has a "strong and powerful impact power system of hydraulic + nitrogen". The system has the advantages of high efficiency, less energy loss and maximum impact energy. The breaking hammer of DOPRO can provide strong impact energy.
Impact energy enhanced structural design
DOPRO crushing hammers adopt the most scientific and excellent design concept, increase the stroke of piston and cylinder body, and make the matching efficiency of crushing hammer and main engine
the highest.
Flow adjustable device
The device can effectively adjust the flow from the excavator or power source, so as to adjust the required striking force and striking frequency according to the rock conditions. According to the rock hardness, the impact frequency is adjusted. The impact force is large, the speed is slow, the impact force is small, and the speed is fast.
