Abstract
According to the present invention a static mixer comprises a passage for the flow therethrough of a liquid or a suspension of particulate solid in a liquid, said passage having in the direction of flow a lengthwise divergent portion followed by a lengthwise convergent portion. An inlet for fluent material to be mixed with the suspension may converge with and project into the divergent portion. Cement and coal slurry may be mixed in this apparatus.

A method of mixing which comprises passing a liquid to be mixed through a passage having in the direction of flow a lengthwise portion with a divergent wall followed by a lengthwise portion with a convergent wall with the lengthwise portions diverging and converging in a linear manner, and introducing fluent material into the divergent portion of the passage through at least one inlet channel converging with and projecting into said divergent portion for mixing with said liquid.
A static mixer comprising a passage for the flow therethrough of a liquid, said passage having in the direction of flow a lengthwise portion with a divergent wall followed by a lengthwise portion with a convergent wall, at least one inlet channel converging with and projecting into said divergent portion of the passage for introducing fluent material to be mixed with the liquid, said lengthwise portions diverge and converge in a linear manner, said divergent wall and said convergent wall each having an innermost curved surface against and along which fluent material flows, and each said innermost curved surface being formed by the frustum of a right cone and being generally smooth and uninterrupted.
