The Bond Ball Mill Work Index is a measure of the resistance of the material to grinding in a ball mill. It can be used to determine the grinding power required for a given throughput of material under ball mill grinding conditions. It is a 'locked cycle' test conducted in closed circuit with a laboratory screen.

Synthetic resin bonded grinding tools are highly abrasive and characterised by cool, "gentle" grinding of the workpiece with a high stock removal rate. They are preferred for grinding carbide, cermet, highalloy steels and other metallic materials. A further development of the synthetic resin bond is the metal hybrid bond.
Resin Bond Grinding Wheels. Resin bond is the most versatile of all bonding systems. cBN Resin bond grinding wheels are formulated for specific grinding applications. Our proprietary formulations were derived from years of technical input from our engineering team and clients.
