Foundry
Bentonit is used as a binder in foundry sands in molds production. Silica sand is the main component in foundry sand. It forms a structural framework of the mold due to bentonite as it binds sand particles which results in the mold strength.
Pelletizer
Bentonit is commonly used in pelletting of iron ore. Bentonite plays an important role in using degradable iron ores with low grades upon pelleting. While activated calcium bentonites swell about 5-6 times of their volume, Sodium bentonites can swell up to 25-30 times. Swelling is directly influenced by the Enslin value required for the pellet. During drying, the surface tension forces are reduced; and, in pellet strength, only the adhesion forces become part of the activity. With the addition of sodium bentonite, the duration of the water is extended and additional binding forces are obtained.
METABOND MC
-
METABOND MC Bentonite is used as a bonding material in the preparation of moulding sand for the production of cast iron, steel, and non-ferrous casting. The unique properties of bentonite yield green sand moulds with good flowability, compactability, and thermal stability for the production of high quality castings.
