High Performance Diamond Core Drill Rig For Geology / Mineral Exploration Core Drilling

Description:

1. Core drilling machine, more rational rang of rotating is available and its rotating speed has 8 grades. With powerful drilling capacity, the rated drilling depth comes up to 1,000m with wire line 71mm drill rod.
2. The drill is aligned a water brake for Steady and smooth deep hole drilling.
3. Supplying oil with a simplex gear pump, it is easy for installation and operation; The hand-operated oil pump can be put in use to hoist the drilling tools in hole upon the power engine failing to operate.
3. With large spindle I.D. 80mm, the rig is fed with double hydraulic cylinders with longer stroke up to 600mm. With strong technological adaptability, the rig can be adapted on many field, especially on large diameter drill rod drilling, with wire line coring (upper part coring). Thus its more effective in improving drilling efficiency with less incidents in hole.
4. It is easy to get to know the conditions in hole with an antivibration meter. Less in operating handles, the rig can be operated credibly and flexibly.
6. It is compact in construction, rational in overall arrangement, moderate in weight, convenient in assembling and wide in range of rotation speed.

Advantage
 
1. High Efficiency
2. Easy operation
3. Safe and reliable 

Application range:

1. Geological exploration, engineering geology investigation and kinds of survey holes on concert structures.
2. Diamond bits, hard metal bits and steel-shot bits could be selected to different layers
3. The rated drilling depth is 100m, we are using dia.75mm bit. Depth is 180m, we are using dia.46mm bit and the drilling depth cannot exceed 110% of its capacity, the allowable max. Diameter if initial hole is 150mm.
