Figures in the body of the chart above are pipe sizes recommended on a 100 PSI system to carry air with less than 1 PSI loss. When measuring lengths of runs, add 5'' of length for each pipe fitting. If carrying 120 PSI pressure these sizes will carry slightly more air than shown, or pressure loss will be slightly less than 1 PSI.
Reverse Circulation drilling can be among the cheapest forms of surface drilling. For more information on the true cost of RC drilling you can read more here! . In geneal, RC drilling is slower and costlier but achieves better penetration than RAB or air core drilling; it is cheaper than diamond coring and is thus preferred for most mineral exploration work.
[Drilling] The part of the bit that includes a hole or opening for drilling fluid to exit. The hole is usually small (around 0.25 in. in diameter) and the pressure of the fluid inside the bit is usually high, leading to a high exit velocity through the nozzles that creates a high-velocity jet below the nozzles.
Rotary Table TSC RT series rotary table is provided with high reliability and serviceability. The rotary table structure has been designed to provide maximum strength to ensure larger load, increased safety and well-fit between bearings and gears.
The range of rotary drilling bits includes geometries and cemented carbide grades for different surface and compressive strengths, abrasiveness, massiveness and homogeneity of rock as well as for various penetration rates and capabilities and characteristics of the drill rig. Innovative bearing technology and improved geometry, materials and machining methods provide longer bearing life.
