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.
