Products Description
LEANOMS
This NUMA100 DTH Hammer has a superior flushing-off action and is less likely to obstruct the rock. Drilling speed is 15-30% faster and 20-30% more efficient than the standard version, with 20-30% energy savings.
The internal structure size of the NUMA100 DTH Hammer is designed using the most recent modern rock drilling theory, which allows for the best energy transfer, the largest single impact work, and the fastest rock drilling speed.
When the drill rig is raised up in the event of debris and clay jams during drilling, the unique taper reducer design may substantially minimize the lifting resistance and failure of the NUMA100 DTH Hammer.
The primary components of the product use a specific computer-controlled heat treatment method to permit the inclusion of a small quantity of high-pressure water in the compressed air for wet rock drilling in order to reduce dust pollution in the drilling operation and safeguard the operator's health.
When drilling, the NUMA100 DTH Hammer always remains at the bottom of the hole, directly impacting the rock. This makes it different from conventional pneumatic rock drilling instruments. High pressure air enters the hammer through the drill pipe, runs out from the drill bits, and is then utilized as exhaust air to blast out the bottom of the hole's cuttings. The drill rig's rotation motor provides the rotational force operating on the NUMA100 DTH Hammer, while the feeding device's draw force provides the force that is transferred to the hammer through the drill pipe.
