Sand cores are removed from metal or plastic coatings by exposing the cores to a humid atmosphere for a sufficient time to weaken the binder of the sand cores. The sand is then shaken from the casting. Metal or plastic castings with hollow passages are produced by forming a casting around the sand core bound with a suitable binder followed by exposing the casting and sand core to a humid
Bentonite is used in drilling fluids to lubricate and cool the cutting tools, to remove cuttings, and to help prevent blowouts. Much of bentonite’s usefulness in the drilling and geotechnical engineering industry comes from its unique rheological properties. Bentonite has been widely used as a foundry-sand bond in iron and steel foundries.
Since deposits are often not uniform in composition, bentonite from a single pit may be separated into several stockpiles, which subsequently are blended to obtain the desired composition. Bentonite is usually processed by breaking large pieces into smaller fragments, drying at low to moderate temperatures to remove water and other volatiles without altering the molecular structure of the bentonite, and grinding to the desired size.
Bentonite A flow diagram for bentonite processing is provided in Figure 11.25-5. Mined bentonite first is transported to the processing plant and stockpiled. If the raw clay has a relatively high moisture content (30 to 35 percent), the stockpiled material may be plowed to facilitate air drying to a moisture content of 16 to 18 percent.
Sodium Bentonite (also known as Western Bentonite): Western bentonite is known for its ability to absorb and hold large amounts of water and for the resulting qualities of its high swell (bigger increase in volume) and high viscosity. It is good for green sand mixtures requiring high dry strength and hot strength, such as for iron and steel
Bentonite (/ ˈ b ɛ n t ə n ʌ ɪ t /) is an absorbent aluminium phyllosilicate clay consisting mostly of montmorillonite.One of the first findings of bentonite was in the Cretaceous Benton Shale near Rock River, Wyoming.The Fort Benton Group, along with others in stratigraphic succession, was named after Fort Benton, Montana in the mid-19th century by Fielding Bradford Meek and F. V. Hayden

Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. The term "sand casting" can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries.Over 60% of all metal castings are produced via sand casting process.

Soil-Bentonite Backfill Properties. The most important property of SB backfill is a low permeability. Typically SB backfill has a permeability in the range of 10-6 to 10-8 cm/sec. Environmental projects often require a permeability less than 1 x 10-7 cm/sec, but a levee or dewatering project may require a permeability less than 1 x 10-6 cm/sec. Either value is achievable with the right mix of
