Abstract: A concrete transit mixer can include a cabin having four doors for people to enter and exit the cabin, and a rotatable drum for mixing and pouring concrete. The mixer can include a water tank mounted below the cabin and a fuel tank mounted below the cabin. The mixer can include four distinct sets of steps to allow people to climb up to each of the four doors to enter the cabin.

Abstract: Methods and apparatus for reducing the content of controlled acidic pollutants in clinker kiln emissions are disclosed. The methods and apparatus include introducing bypass dust produced during production of clinker into one or more locations between the preheater exhaust and the inlet to a dust filter including into a gas conditioning tower. Total bypass dust separated from the kiln exhaust gas may be used. The bypass dust can be separated into a fine and coarse portions. Fine or total bypass dust can be mixed with water to form a bypass dust slurry that can be introduced into the gas conditioning tower. Bypass dust can be used to reduce the content of acidic pollutants such as hydrogen chloride HCl and sulfur oxides SOx from clinker kiln emissions.
