How Does Rotary Rock Bit Work?
Tricone 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.
