Bentonite binder effective strength (BESt) test for unfired iron ore pellets

Bentonite binder effective strength (BESt) test for unfired iron ore pellets

Iron ore pellets use bentonite clay as binder at dosages of from 0.5% to 1.0% of the moist iron ore concentrate weight. As a natural product, bentonite has variable water-absorption and binding properties depending on its source. Therefore, it is best to have a method for evaluating a given bentonit...

Zusammenfassung:Iron ore pellets use bentonite clay as binder at dosages of from 0.5% to 1.0% of the moist iron ore concentrate weight. As a natural product, bentonite has variable water-absorption and binding properties depending on its source. Therefore, it is best to have a method for evaluating a given bentonite to determine how effective it would be before it is purchased for use to bind concentrate into pellets.
