Effect of clinker composition on grindability

Effect of clinker composition on grindability

 · The Bond work index is the most widely used method in the for determining grindability, because it has been shown to give results in agreement with operating practice. Clinker with higher work index requires more energy to be ground to a given surface area than clinker of a lower work index. Chemical and physical properties of the clinker are influenced by many factors including ...

Work indices have been obtained from grindability tests on different sizes of several types of equipment, using identical feed materials (Lowrison, 1974). The values of work indices obtained are indiions of the efficiencies of the machines. Thus, the equipment having the highest indices, and hence the largest energy consumers, are found to be jaw and gyratory crushers and tumbling mills ...
