Origin	China
Model Number	Casting Sodium Bentonite
Brand Name	kunyin

The sodium-base bentonites as the binder of iron-ore pellet can remarkably increase the strength and rupture temperature of green pellets, and expand the roasting area. It can reduce the cost and obviously improve the economical effect of iron and steel enterprises due to its good permeability, high sulfur-removing capacity and low returns-out.
