OPERATOR TRAINING COURSE

OPTIMISATION OF TRICONE DRILLBIT PERFORMANCE

Training is conducted in the form of lectures, with the extensive use of visual aids, followed up by on-site practical observation and training.  We can modify our format to meet virtually any client requirements.

Many clients have found an improvement in drillbit performance and a reduction in drilling costs, after conducting these courses at their mines.

                1. INTRODUCTION

                2. BASICS OF THE TRICONE

                3. HOW DOES A ROCKBIT WORK?

                4. FACTORS THAT AFFECT DRILLBIT PERFORMANCE
