SD Shank Hammer From 4''-12'' With Working Pressure 1.0-2.5Mpa Use For Quarrying
Product description
The DTH Hammer method provides one of the most efficient and versatile ways of drilling in a wide variety of rock conditions for many different applications. It provides fast penetration even in the hardest rock with constant speed throughout the length of the bore hole with the added benefits of accuracy and alignment to give good clean usable holes. DTH does not rely on heavy machines with fast rotational speeds or heavy down-thrusts; it only requires that the hammer be subjected to sufficient thrust to initiate the percussive operation and that there is the appropriate amount of rotational speed, usually around 28 to 40rpm, to relocate the drill bit on the rock face to produce the optimum size of cutting and minimal dust production. Performance, reliability, minimal spares usage, long service life and overall cost effectiveness are the hallmarks of a well-designed and manufactured ‘World Class’ DTH hammer that brings benefits to both the driller and the operating company – it is important to go for quality and not price when making the choice to purchase your DTH hammer.
Product Advantages:
1.Suitable for all types of rock (except clay)
2.Greater versatility in terms of hole sizes
3.Low capital outlay
4.Simple and easy to operate

Before beginning to drill, there are several factors that you
should know:
1. Hole Size:
In most instances, the outside diameter of the hammer closet to the
hole size being drilled should be used for most efficient drilling.
This reduces the instance of the collapse and makes cleaning the
hole easier. One needs to take into account that there must be
sufficient annular area around the hammer to pass the drilled
cuttings. This normally will supply the most efficient operating
conditions.
2. Air consumption:
The amount of compressed air available must be taken into
consideration when using a down hole hammer. Different size hammers
require different volumes and pressures in order to properly
operate. Generally, as the size of the hammer increases, higher
volume and lower pressure is needed for peak performance. Be sure
to refer to the air consumption chart.
3. Big capacities:
The larger the bit and hammer, the greater the rotational Torque
and feed/pull back requirements become. Do not exceed the drill
rigs Capacity.
Product application
At present, DTH drilling tool is widely used in underground mining, quarries, hydraulic and Hydro-Power Engineering, water well drilling, Mineral exploration, anchoring hole drilling, geothermal engineering, Subway excavation, another civil engineering.
DTH is one of the most efficient ways of drilling rock, using a rapid hammer action to break the rock into sizeable chips which are then evacuated from the bore hole by the air exhausted from the DTH Hammer. The technique provides fast drilling of accurately aligned, straight and clean holes in most ground conditions.
