Leopard™ DI560 diesel-powered, down-the-hole (DTH) drill has excellent mobility, a smaller footprint and the ability to serve multiple sites. It is a machine trusted by mining and constructionpanies, and contractors engaged in pre-split and regular production blasthole drilling. Leopard DI560 is designed for drillingmm (3½-6½") holes. zr1qOEok7twz Feb 28, 2019 · In rotary drilling, the rig provides enough shaft pressure and rotary torque. Tt drills and rotates on the rock at the same time, which exerts both static and dynamic impact pressure on the rock. Dg7E0Py05mgY Basic Rotary Drilling system consists of 4 groups ofponents:-Prime Movers. Prime movers are also known as power system of a rotary drilling rig as they provide power to the entire rig. When drill rigs were started, steam engines were used to provide power. Use of diesel and gas engines wasmon post World War II. ocVQVRewpgxF • relatively small, light, and mobile drill rigs can be used; • low drilling costs; • down the hole drilling provides the potential for minimal hole deviation with production rates of 5 to 15 m/hour (Kutzner, 1996). There are currently four basic concepts in down the hole (DTH) drilling PQ2tFTcqWb13

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 ofpressed 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.
