Reverse Circulation Water Well Drilling Rig Reverse circulation (or RC as it`s more commonly known) drilling is an essential tool in the mining industry. In addition to other oil rigs and drill rigs, reverse circulation drills assist in the productivity and accuracy in mining jobs.
It is the preferred method of mineral exploration, drilling and in-pit grade control because it is fast and cost-effective.
What is RC Drilling?
Reverse circulation drilling is the predominant technique based on a number of advantages.

Natural rubber is a typical resource-constrained industry. It has strong selectivity for environmental climate and irreplaceability in the region. Its planting area is limited, and its output growth is limited. The main material of synthetic rubber is oil, and every 8 tons of crude oil The production of 1 ton of synthetic rubber, therefore, the vigorous development of renewable rubber industry has great potential in the Chinese market.
RC drilling is a drilling method involving a large rotary drill and Air Compressor that yields high quality mineral and rock samples, free from contamination and material interference.
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 metres.
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.
.A higher percentage of uncontaminated cuttings
.Drilling rate similar to open hole drilling, but can often be faster and penetrate greater depths
.One of the most accurate drilling methods
.Quick retrieval of sample rates
.Dry samples allow for easier analysis
In 2011, the profit of China's reclaimed rubber industry increased by 48.16%
China is the world's largest consumer of rubber, and is a country with extremely scarce rubber resources. Every year, over 75% of natural rubber and over 40% of synthetic rubber are imported, and recycled rubber has become China's third largest source of rubber. At the end of 2011, there were 147 reclaimed rubber manufacturing enterprises in China, and the total assets of the industry reached 5.235 billion yuan, a year-on-year increase of 29.99%. The data show that: In 2011, China's large-scale reclaimed rubber manufacturing industrial enterprises achieved main business income of 17.736 billion yuan, up 32.56% year-on-year; total profits reached 1.168 billion yuan, an increase of 48.16%.
