These bonds, equal in strength and stability to the principal bonds along the polymer backbone, tie the polymers together, thus dramatically increasing molecular weight. In fact, the length of the polymer chains and, therefore, the physical properties, are much better than can ever be achieved without crosslinking.
Bond work index reduction In applications where the HPGR is followed by ball milling, the induced micro fractures generally result in a reduction of the Bond Work Index. For most ores this reduction ranges between 10-25%. Obviously this allows for grinding at either an increased throughput rate, at a reduced power input, or
