Description


Choosing the right hammer is largely determined by hole size and type of rock formation. Ideally, the size of the hammer should match the required hole dimension as closely as possible, leaving just enough space for cuttings to evacuate the hole.

1.according to China's mining conditions, to absorb the advanced technology of domestic and foreign impactor and design and manufacture of the latest products.


2.reasonable selection of materials, advanced manufacturing technology, quality assurance perfect.


3.has higher drilling speed.


4.can provide hardening treatment in order to prolong the service life and reduce the cost of use.


5.single impact power is large, and the power consumption of broken rock is low.


6.piston and bit weight to have the best momentum transfer.


7.the modern theory is adopted in the structural design, which makes the stress wave duration longer, the stress amplitude is lower, and the piston life is long.

Applications


It is mainly used in geological exploration, coal mine, water conservancy and hydropower, highway, railway, bridge, construction and so on.
