What Is Tricone Drill Bit ?

Tricone Drill Bit - a drilling method that uses a roller bits. In roller-bit drilling, rock is cut by hard-alloy teeth projecting from rolling cutters, which rotate on the drill-bit bearings. Inturn, the drill bit rotates at a high rate, and presses against the bottom hole with a high axial force. The teeth of the rolling cutters roll over the bottom hole and, owing to the large stresses that develop in the area of contact between the teeth and the rock, cut the rock by crushing and chipping. As the hardness of therock increases, the rotation rate decreases and the axial force increases. Destroyed at the mine the rock is removed to the surface by air compressor, mud pump, or a combination of these methods.

All of our bits are manufactured according to strict standards, set forth by the American Petroleum Institute (API). And classified according to characteristics set forth by the International Association of Drilling Contractors (IADC).

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.
