Tungsten carbide roller cone drill bit wear is caused by the cone balling, mainly due to carbide roller cone rock bit drilling very soft water, drilling pressure is too high; insufficient air flow slag, slag rock can not be successfully discharged; in the high density or high-grade ore drilling, but also easy to produce bad slagging this phenomenon. Carbide teeth broken off the main causes is due to rock too hard; improper carbide drill selection; drilling rate is too high. Causes the outer tooth wear is mainly due to two points, one rock hard; second point is that long-term operation, the drilling in iron ore.
