Introduction to Pneumatic Conveying of Solids

What is pneumatic conveying? Pneumatic conveying is the movement of solids through pipe using gas (usually air) as the motive force. It differs from hydraulic or slurry conveying in that the gas expands continuously along the pipe length. The flow regime in the pipe depends greatly on the ratio of solids to gas and the particle characteristics.

Carbonatation Wikipedia

Carbonatation is a slow process that occurs in concrete where lime (CaO, or Ca(OH) 2 ()) in the cement reacts with carbon dioxide (CO 2) from the air and forms calcium carbonate.. The water in the pores of Portland cement concrete is normally alkaline with a pH in the range of 12.5 to 13.5. This highly alkaline environment is one in which the steel rebar is passivated and is protected from

Manufacturing process | Lafarge Cement, concrete

In the air lift, the raw meal is lifted to the silo by compressed air to the air slide and then stored and homogenized in a concrete silo. Raw meal extracted from the silo, now called kiln feed, is fed to the top of the preheater via an air lift called the Poldos for pyro-processing.

Caisson (engineering) Wikipedia

In geotechnical engineering, a caisson (/ ˈ k eɪ s ə n / or / ˈ k eɪ s ɒ n /; borrowed from French caisson, from Italian cassone, meaning large box, an augmentative of cassa) is a watertight retaining structure used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, or for the repair of ships. Caissons are constructed in such a way that the

How Cement Is Made Portland Cement Association
