High Performance RC DTH Hammer Mining Drilling Tools Corrosion Resistance
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.
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.
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.
