To increase efficiency and lower drilling costs, blasthole rigs are expected to deliver more and more energy to the drill bit. As a result, drill bits must be carefully designed and manufactured to not compromise the productivity and efficiency of increasingly complex and expensive drilling systems. Bits have become an even more critical and vital component in this process. Tricone bits - Verified in the lab, for superior performance in the field.Our tricone bits product line promises the highest performance, reliability, and availability. This effectively results in a lower drilling cost. With sealed bearing product line, takes the guess work out of drilling. Our bits are designed to increase bit life even further where the application presents restrictions to drilling. Our advantages:1. Advanced technologyHKX series is a product of our extensive field experience combined with sophisticated research and development, including advanced simulation technology.2. Balanced cutting structureCutting structures (the placement of inserts) and bearing geometry have been optimized to distribute load more uniformly over the bearings. The result is a smoother and more balanced cutting structure, allowing sustained penetration rates over longer periods of time, with reduced risk of bearing failure. As an added bonus, full body armour minimises wear on both bit body and shirt tail.3. Lower total drilling costsOur bits are designed with streamlined lug allowing the ejection of larger pieces or rock. Ultimately, you can now look forward to faster penetration rates, longer bit life, and significantly lower total drilling cost. It now takes less time to get the job done! Specifications: HKX745-229( 9"IADC545 )APPLICATIONS:Application for drilling soft formations with low compressive strength and high drillability, such as shale, soft limestone, soft dolomite and coal bed, etc(Protodikonov's Hardness Coefficient of Rock f=9).Parameters:IACD CODE: 745Bearing structure: Roller-Ball-Second Thrust-Roller-First Thrust/Sealing, abrasion-resistance carbide button insert on the bearing surface.Circulation Type: Jet AirCutting Structure:-Inner Rows: Ballistic-Gage Rows: Spherical-Gage Bevel Protection: FlatPin connection: 6 5/8" REG(API)Nozzel: Φ22mm(THREE pcs) InterchangeableMetric Bit Diameter: 311mmProduct Weight: 98.5 KG Bit Legs ProtectionCarbide alloy button insert on the legs' surface, back and top space of legs build up welding of abrasion-resistant alloy. Operating Suggestions:Weight on Bit: 49000-85000 LbsRotary Speed: 80-50 RPMAir Back Pressure: 0.2-0.4 MpaRotary Drilling Rotary drilling is mostly used to drill big holes in large quarries, open pit mines, petroleum extraction, and other ?elds:(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 FEATURES1. Unique bearing structure design to assure the durability and improve the bearing resistance2. Bearing journals with increased lubrication and reduced heat generation3. Bit leg insert wear buttons to reduce wear and prevent debris build-up in bearings4. Cutting structure and bearing design optimized assure the productive and durable performance during drilling5. 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.Our commitment ImproveSafetyImprove Productivity -Increase ROPReduce Total Drill Consumable SpendDrill Consumable Management andReportingConsolidate Supply BaseReduce Administrative BurdenVendor Held and Managed Stock on SiteImprove Product Storage and Manual Handling
