SRC040 Fast and Continuous Reverse Circulation RC Drill Bit For Sample Drilling
Product Introduce: Much like air core drilling, RC drilling returns cutting to the surface through an inner tube inside the rod. This is achieved by blowing air down the rods at a rate up to 1500 Pascals. This creates a pressure differential that pushes cuttings and water up via air lift. The drilling component is powered by a pneumatic reciprocating piston (also known as the hammer), which drives a steel drill bit. The two most commonly used drilling bits in RC systems are the fixed cutter and roller cone, both of which are advantageous depending on the project and geographical location of the site. RC drilling is primarily used on large machinery and drill rigs and often goes to depths of 500 meters. High quality RC equipment also has the ability to dry out the rock with large air compressors before the drill hits, which provides dry rock chips and, in turn, better samples. Adavantages: 1. Customized acceptable 2. Raw material is very high quality alloy metal, we focus on quality and care clients' concern. 3. Harden treatments Technical Parameters RC bits Model SRC040
Working principle The on-board compressor delivers power to a pneumatic reciprocating
piston. The piston, in turn, drives a tungsten-steel drill bit
which is purpose designed to be able to crush hard rock. Similar to air core drilling, drill cuttings are returned to
surface inside rods. We achieve this through the use of dual wall
drill rods: an outer drill rod with an inner tube. When compressed
air is blown through the rod, the volume displaces the air, lifting
the samples to the surface. Once cuttings reach a diverter at the top of the hole, they’re
moved through a hose and around the cyclone, which slows the sample
down. From the cyclone the sample goes over a splitter that
delivers a percentage of the entire sample into a sample bag. The
exploration drilling team then collect the samples aligned to the
hole depth and lay them out for the client to log, and then
transport to the lab for assay. Detailed Photo: About us: SOLLROC Reverse Circulation drilling (RC) ,from size 3’’ to 5.5’’, is a technique of drilling that uses dual wall drill rods that consist of an outer drill rod with an inner tube. By using compressed air to extract rock fragments sample,the samples travel through rods to a sample splitter at surface, avoiding all contact between the samples and the borehole wall that allows samples to be retrieved with minimal contamination,which is mainly used in deep hole exploration and mining grade control.
