properties of molding material dry strength - ` it is the strength of the molding sand in dry conditions. ` when the molten metal is poured in the mold, the sand around the mold cavity is quickly converted into dry sand as the moisture in the sand evaporates due to the heat of the molten metal. ` at this stage the molding sand must posses the sufficient strength to retain the exact shape of

How Cement Is Made

the heated air from the coolers is returned to the kilns, a process that saves fuel and increases burning efficiency. after the clinker is cooled, cement plants grind it and mix it with small amounts of gypsum and limestone. cement is so fine that 1 pound of cement contains 150 billion grains.

How aluminium is produced

How Aluminium Is Produced

the production waste, white mud, can be used to make high quality cement. it takes 4 tonnes of nepheline and 7.5 tonnes of limestone to make 1 tonne of alumina alumina has unlimited shelf life but it has to be stored under the right conditions as it will absorb moisture at the first opportunity, so alumina producers prefer to ship it off to smelters as soon as possible.
