The mixology of slurry

Tanks that are used to mix acidic slurries are often internally lined with rubber as acidic slurries corrode the steel However the rubber has to fit around the baffl This can introduce gaps or points of weakness in the rubber lining and therefore the tank itself meaning tanks have to be closely monitored in order to avoid tank failure...

A Perforated Baffle Design to Improve Mixing in Contact Tanks

In this study a perforated baffle design is proposed to improve mixing in contact tanks Turbulent flow through the perforated baffle is studied at the perforation hole scale The contribution of jets emerging from the perforations to the mixing process is evaluated in terms of standard mixing indexes for various perforation parameters such as the solidity ratio and hole diameter...

Baffles are usually needed to stop the swirl in a mixing

Baffles are usually needed to stop the swirl in a mixing tank and without baffles the tangential velocity coming from any impeller will causes the entire fluid mass to spin The straight flat plate of a metal that run along the straight side of vertically oriented cylindrical tank or vessel were the most common type of baffles...
