RC series reverse circulation DTH Hammer is the latest developed product of our company. It is mainly used for deep exploration drilling and ore grade control.
R.C. Drilling, referred to as "Centre Sample Recovery"or "Dual Wall Drilling", employs a Dual Wall PIpe where the drilling medium, normally high pressure air, is passed between the outer and inner tubes down to the face of the drilling bit where it is returned up the centre tube along with the sample cut by the drill bit.
RC hammers and bits are used in hole drilling in mines, hydrology and water well, geothermal well, geothermal air conditioning well, geologic exploration, gravel stratum, etc Especial suitable for complicated formation (Formation loose, difficult to drilling and unstable of hole wall), exhausting for deep hole, environment protection.
THE USE AND THE ADVANTAGES OF THE R.C. DTH HAMMER:
No contamination
The R.C. System collects sample throungh the recovery holes in the face of the drill bit immediately as the cuttings or sample is formed. The drilled sample does not have to travel the length of the hammer where contamination and loss of sample takes plasce.
Higher Production
In broken and fractured ground conditions, the R.C. will often out perform the conventional hammer in terms of penetration rates.
Dry Sample
Even in certain water bearing stratas it is still possible to collect ad dry sample because the cuttings(sample) are collected as they are formed through the face of the drill lbit.
Higher Sample Recovery
Because the sample is collected throungh the face of the drill bit there is no loss of sample when drilling through broken or fractured ground. And since the bit matched to the chuck size, there is very little bypass of sample and recovery rates of up to 98% are generally achievable.
Our company has passed and strictly implemented the ISO9001, 2008 quality management system, has independent import and export rights, obtained a number of product invention patents, won the Alibaba special contribution award, Hunan Network Chamber of Commerce vice president unit, A, hardware tools industry top ten excellent network operators, 315AAA quality service integrity units and other honors.
