Mining and drilling operators rely on DSTI products to tackle a wide variety of demanding jobs for optimal productivity and greater component longevity.
Down-the-hole (DTH), in-the-hole (ITH) and blasthole drill rigs are integrated with a rotary union (swivel joint) for delivering a consistent and dependable supply of compressed air to the DTH percussion mechanism (hammer). Air travels from stationary hoses on the rotary drill, through the rotating drill string, and into the hammer. The fast hammering action breaks hard rock into small flakes that are blown clear by the air exhaust from the hammer.
Since 2009, DSTI has supplied more than 750+ field-proven, air swivels for DTH, ITH and blasthole operations used in quarries, open pit mining, underground mines, construction, exploration, oil and gas, and geo-thermal drilling operations. Each featuring exclusive sealing technology and a heavy-duty construction aimed at eliminating common industry failures.
To ensure maximum uptime, DSTI swivels can be designed for quick and easy serviceability. In a matter of minutes technicians can gain access to replace the swivel’s main seals; and in most cases while still installed in the equipment.
In addition, DSTI also provides custom rotary unions for other applications that require unrestricted rotation while transferring air, water, mud, hydraulic oil and electricity.
