Portable core drilling rig construction in Belgium

The Boyles C5/C5C surface core drilling rig is compact, yet powerful. Its compact design makes it easy to position and transport, even by helicopter. During helicopter transport, the rig is broken down into six main modules and each module is equipped with lifting points to ensure safe and effective transport. Boyles. . The Christensen range of surface core drilling rigs has, over many years, established itself a reputation for reliability and ease of use. Many Christensen rigs are. . For underground core drilling exploration tasks, Epiroc offers the well-established and trusted Diamec range of machines. Diamec rigs are available in a wide variety. [pdf]

Roman Diesel Down-the-Hole Drilling Rig Method

A down-the-hole drill, usually called DTH by most professionals, is basically a jackhammer screwed on the bottom of a drill string. The fast hammer action breaks hard rock into small cuttings and dust that are evacuated by a fluid (air, water or drilling mud). The DTH hammer is one of the fastest ways to drill hard rock. The system is thought to have been invented independently by Stenuick. Origin of the nameDTH is short for “down-the-hole”. Since the DTH method was originally developed to drill large-diameter holes downwards in surface-drilling applications, its name originated from the fact that the percussion mechanis. . In DTH drilling, the percussion mechanism – commonly called the hammer – is located directly above the drill bit. The drill pipes transmit the necessary feed force and rotation to the hammer and the bit, along with the flui. [pdf]

Diesel engine air compressor cylinder

When you turn on the engine, the battery powers the pistons in the cylinder up and down. The pistons push the air through the cylinders, into a combustion chamber where it is compressed. Compression forces the molecules in the air to move faster, which naturally heats the air. Fuel is then injected into the hot,. . While the above process occurs, additional fuel is delivered by the system. The fuel is pumped from the fuel tank, passing through filters, a higher pressurization pump,. . During the ignition process, air is also pumped to the cylinders. On some engines, this air passes through a simple air cleaner en route. [pdf]
