Recommended operating parameters of SA series roller cone bits for mining:
Bit type | Normal WOB KN/MM (BIT DIA.) | Rotary Speed (rpm) | Cutting structure Main features | Applicable formation |
SA632 | 0.801.00 | 11050 | Conical spherical compacts in inner row, dull wedge compacts in outer row | Medium hard with high compressive strength or high abrasive formation, such as limestone, sandstone, dolomite and chert, etc. |
SA832 | 1.101.30 | 90--60 | Bullet shape or ball-nose compacts in inner row, dull wedge compacts in outer row | Hard formation with high compressive strength and high abrasiveness, such as magnetic quartzite, quartzite and granite, etc |
Note: the upper limits of WOB and RPM recommended in above table should not used simultaneously
