Kerf roller cutter is a kind of TCI roller cutter widely used in raise boring equipment. The cutter surface has multiple annular grooves (chipways), and the carbides are orderly distributed on the cutter body surface outside the chipways.
1. Adopt tungsten carbide with a unique button shape.
2. Use wear-resistant buttons to minimize the wear of the roller cutter.
3. The bearing structure is a pair of tapered roller bearings.
4. Use high-quality metal seals.
5. The roller cutters can be repaired and customized.
1. Applicable rock hardness: protodyakonov scale of hardness 11≤f≤15.
2. Recommended WOB of roller cutter: 100KN~200KN.
3. Maximum WOB (weight on bit): 245KN.
4. Recommended cutterhead rotation speed: 3-15 RPM.
5. Maximum linear velocity: 90m/min.
