MasterRoc ABR 7

Anti-abrasion and dust-reducing agent for hard rock tunnel boring machines

How does MasterRoc ABR 7 work?

MasterRoc ABR 7 liquid foaming agent is specifically designed to reduce abrasive wear to the cutting tools in tunnel boring machines (TBM), and to substantially reduce dust formation during excavation. It lowers inner friction and abrasiveness of the face at the cutterhead as well as at the screw conveyor.

Recommended uses:

MasterRoc ABR 7 liquid foaming agent is recommended for use in hard rock TBM excavation.

What are the unique features of MasterRoc ABR 7?

Reduces abrasive wear in cutting tools
Reduces dust formation, leading to improved working environment for TBM operators
Lowers inner friction and abrasiveness of the face at the cutterhead as well as at the screw conveyor
Compatible with highest environmental standards
Based on renewable materials

What are the benefits of MasterRoc ABR 7?

Reduces TBM down time due to reduced wear, which means less frequent cutter changes, thus more time available for excavation
Improves cooling of the cutter head, improving the rubber seal durability, and extending the life of the cutter bearing assembly
Improves muck transfer, resulting in reduced risk of blockage, cleaner cutter discs and cutter head area, making maintenance easier and reducing cutter disc changing time
Overall cost savings due to higher advance rate and lower maintenance cost
Reduces power consumption
