Our bentonite widely used in production of cast steel and iron applying wet, dry, dry-surface, high pressure etc different technology.
Fertilizer grade bentonite is made as raw bentonite ore as raw mateiral, aftre dring,grinding and packing .
calcium base bentonite main use for foundary casting as general application.
sodium base benonite is using for foundary casting as sand or adhensive to make sure accurate and sleek surface.
Characteristics of our bentonite:
Less addition, higher strength
Good ventilation
High hot wet compressive strength and good sand inclusion resistance
High temperature resistance
Improving casting parts surface finishment
