• Electrographite grades
  

CARBONE LORRAINE has recognised the need for improved carbon brush materials, particularly for DC equipment used in the Open Pit/Open Cut type of mining.

Extensive laboratory and field testing has resulted in the development of the new CB300 series carbon brush grades that will provide the key element of desired performance:

• Excellent commutation - minimal sparking or erosion
• Stable film (patina) - special treatments for film control and to maintain stable film formation over a wide range of temperature and humidity conditions
• Low friction - minimal commutator wear
• Long life brush

The same degree of performance can be obtained on wheel motors with CARBONE LORRAINE's specially engineered AC series of grades.

For under ground Mining applications, CARBONE LORRAINE's brush grades have been successfully used on all types and makes of equipment for many years.

The overall benefits of the use of these carbon brush grades are improved machine performance and a reduction in maintenances costs.
