In metallurgical applications, the unit process of balling aims at achieving highly permeable large aggregates with a built-in ability to withstand large crushing forces. The latter can be achieved by resorting to particular binder additions which confer structural integrity to the ball or pellet after a specified curing period. The ability to ...
