Abstract
The device according to the invention for performing chemical and/or physical reactions between a solid material and a gas, in particular for preheating, cooling and/or calcining fine-grained materials substantially comprises at least one helical and/or spiral line, in which a gas/solid material suspension is separated by centrifugal forces into a solid material flow and a gas flow and at least one separation chamber which is connected to the end of the helical and/or spiral line and which is connected to a gas line in order to direct the gas flow away or which is formed by a portion of the gas line, a solid material line for directing the solid material flow away being connected to the separation chamber. The helical and/or spiral line opens into the separation chamber tangentially at an angle of at least 30° relative to the horizontal and the cross-section of the separation chamber in the region of the opening is from 0.5 to 1.5 times as large as the cross-section of the helical and/or spiral line.
