Specification Notice

 

Notes:       Note1: The hammers without foot valve are with lower air       and energy consumption, and higher impact frequency; the       drilling penetration is 15% ~ 30 higher and oil consumption       10% lower than the ones with foot valve.         Note2: The AXD shank is Acedrills’ own design.   For brochure and more product information, please click here  to tell us the detail.

 

   To Chose the Right Products 

 

Choosing the right hammer is largely determined by drill machines (mainly compressor output), drilling 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 compressed air to flush cuttings and clean the hole.

 

The optimum range of hole size for blast-hole drilling with DTH method is 90~254 mm (3-1/2” ~ 10”) with 3.5 ~ 8” hammers. Smaller blast holes are generally drilled with top-hammer tools, while larger holes typically with rotary drilling tools. In other applications, like foundation drilling, DTH hammers can be used in hole size up to 1,000 mm (39-3/8”).

 

Usually, the smallest hole diameter a DTH hammer can drill is its nominal size, for example, a 4” hammer would drill a 4” (100/102 mm) hole. The limiting factor is the outside diameter of the hammer, because, as hole diameter reduces, airflow is restricted. Maximum hole size for production drilling is the nominal hammer size plus 1”for 5” and smaller hammers and plus 2 for 6” and bigger hammers, for example, for a 4” hammer the maximum hole size is 5” (127/130mm) while for a 8” hammer the maximum hole size is 10” (254mm).
