Excessive wear, high temperature and cutter blockages are issues in hard rock TBM tunnelling. In most cases, these effects are combated by using a simple water sprinkler system to cool down cutterhead and reduce the dust level. Nevertheless, disc cutter wear, temperature, related cutter blockages and dust remain persistent, especially in abrasive rock conditions.
Normet believes it is time to make a step change and use efficient anti-dust and anti-wear additives. The benefits of our anti-wear additives have been proven in extensive laboratory trials at Colorado School of Mines (USA) and on TBM projects.
