Operation
DTH hammers work by using compressed air to drive a piston back and forth, which in turn strikes a bit that is attached to the end of the drill string. This creates a hammering action that breaks up the rock and allows the drill to penetrate deeper into the ground.
Benefits
Valved drill bits are equipped with valves that help to control the flow of air and cuttings through the bit. This helps to improve the drilling efficiency and reduces the amount of wear and tear on the bit.
- Improved drilling efficiency: The valves help to control the flow of air and cuttings, which improves the drilling efficiency and reduces the amount of time it takes to drill a hole.
- Reduced wear and tear: The valves also help to protect the bit from wear and tear, which extends the life of the bit.
- Increased safety: Valved drill bits are designed to be more stable than other types of DTH drill bits, which can help to reduce the risk of accidents.
- Efficient: Can drill holes quickly and efficiently, even in hard rock formations.
- Powerful: Can deliver a lot of impact energy, which allows them to break up rock that would be difficult or impossible to drill with other methods.
- Versatile: Can be used to drill holes in a variety of rock formations, including hard rock, granite, and soft rock.
- Durable: Are built to withstand the rigors of mining and quarrying operations.
