Rotary Drilling Rotary drilling is mostly used to drill big holes in large quarries, open pit mines, petroleum extraction, and other fields:
(1)rotary crushing by high-point loading to the rock from three cones.

(2)rotary cutting by shear force from drag bits. The rotary cutting can be also used to drill small boreholes in soft rocks.

For example, rotary drilling is often used to drill small holes down to 25 mm in diameter to install bolts in coal mines. The rotary crushing is used in medium to hard rocks, and the rotary cutting in soft rocks.

 

Black Diamond rotary tricone bits are manufactured using premium quality steel and use BD Drill own tungsten carbide inserts that have been developed to suit the toughest applications.

KEY FEATURES

1. Unique bearing structure design to assure the durability and improve the bearing resistance

2. Bearing journals with increased lubrication and reduced heat generation

3. Bit leg insert wear buttons to reduce wear and prevent debris build-up in bearings

4. Cutting structure and bearing design optimized assure the productive and durable performance during drilling

5. Desirable design allow the ejection of large debris, ultimately results in faster penetration rates, longer bit life and lower the total drilling cost.

 

 

BD Drill equipped with over 1000 sets advanced machine,we produce high quality Mining Tricone Bits for years, now we have already established strategic business relationship with world famous mining company, the quality and durability products cutting down the drilling cost, in the meantime, we keep optimise the design to always assure to meet customer requirements.
