Long Life Sealed Bearing Rock Drilling Tools For Mining Industry
What is Mining rotary drill bits?
Mining rotary drill bit is an ideal solution for soft, medium, or hard rock formations, it is connected with the drill stem and rotates along with it, and drive cones to pressed on the rock. Each cone rotates round the axis of its leg and three cones simultaneously revolve around the bit center. The tungsten carbide inserts on the cone shell cause the formation to spall under the weight on bit and the impact load of cone rotating, the debris will be discharged out to hole by compression air. Tricone bits come in several different varieties, and can deal with a wide range of different rock formations. It is important to know the type of formation you are drilling in when selecting a drill bit.
Application
Tricone drill bit is one of the main tools for blast hole and well drilling, mainly used for large-scale open-pit mining, such as open-pit coal mines, iron mines, copper mines and molybdenum mines, also the non-metallic mines. With the increasing in variety of type, it’s also widely used in quarrying, foundation clearing, hydrogeological drilling, coring, tunneling in railway transportation department and shaft drilling in underground mines. The rock breakage by the tricone bit which used in mine is working with both the impact of teeth and the shear caused by slippage of the teeth, which bring high rock breaking efficiency and the low operation cost.

INTERRELATIONSHIP BETWEEN INSERTS REQUIREMENTS AND THE FORMATION
Formation Characteristics | Insert Spacing | Insert Properties | Penetration and Cuttings Production | Cleaning Flow Rate Requirement |
| Soft | Wide | Long and sharp | High | High |
| Medium | Relatively wide | Shorter and stubbier | Relatively high | Relatively high |
| Hard | Close | Short and rounded | Relatively low | Relatively lower |
Advantage:
1. Strictly select the material to ensure the reliable quality. Bad steel and tungsten carbide inserts won't be used.
2. Strictly act according to the ISO9001 standard, and control by full-scale inspection.
3. Sales and support people are highly trained in the latest rock drilling technology and can offer you expert advice on what products will best fit a specific end use application.
Quality Control
1, Raw material selection:To make a good drill bit, it is necessary to select the best material and gatekeeping the quality of the material. We purchase the high-quality steel and strictly control the material composition and size, it main includes the detection of the shape, diameter, reamed diameter, length composition, and flaw of the raw material, Tungsten Carbide and Grease are also the best raw materials on the market.Besides, we marked every different piece of materials before transferred to the warehouse.
2, In strict accordance with the ISO9001 international standards for production.
Carefully control every step of the production, complete each of the production process,
the production process is including blanking, forging, rough turning, heat treatment,fine turning, quenching, assembling, welding, painting, then storage.
Each working process was full inspected, after the qualification, then move to next working process, which to ensure the 100% qualified rate.
