Mining roatry tricone drill bit always used for the drilling of the production hole in open pit mining. According to different rock formation, there should be used corresponding type IADC Code products. Black Diamond with over 24 years experience in the manufacturing of rock tools, now self designed and produced the mining tricone bits that cover the most common used sizes.
Black Diamond tricone bits are designed for the most severe rotary blasthole applications, yet are cost effective for a wide range of drilling needs. The new bit line includes six diameters ranging from 200 mm (7 7/8 in.) to 311 mm (12 1/4 in.). Their carbide shapes and cutting face arrangements are optimized for high wear resistance and improved rock fragmentation, and the aggressive, long-lasting cutting structure delivers a superior rate of penetration.
BD Tricone Drill Bits have demonstrated significantly lower total cost of drilling in head-to-head tests conducted in copper, iron ore and coal mines.
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.
- Unique bearing structure design to assure the durability and improve the bearing resistance
- Bearing journals with increased lubrication and reduced heat generation
- Bit leg insert wear buttons to reduce wear and prevent debris build-up in bearings
- Cutting structure and bearing design optimized assure the productive and durable performance during drilling
- Desirable design allow the ejection of large debris, ultimately results in faster penetration rates, longer bit life and lower the total drilling cost.
