Grinding wheels consist of two main components: the abrasive (cutting) grains and the bonding material that holds the grains together. The size of the grains and their spacing, the type of the bonding material and the abrasive used will determine the structure of the grinding wheel.
Pavement Grinding. Next Generation Concrete Surface (NGCS) is a new grinding method that has produced the quietest concrete pavements in other states. Conventional diamond grinding (CDG) reduces noise from older concrete pavements.
