Apparatus for the treatment of solid, liquid and/or gaseous materials

A method of treating particles of building materials, such as concrete, mortar and the like, to obtain a hardenable mass, which comprises introducing the building materials, together with particles of at least one binding agent and additive, and a liquid, in an apparatus comprising at least three concentrically arranged annular rows of beater paddles, counterrotating the annular rows of beater paddles about a common axis of rotation at a speed of rotation of 800 to 3000 rpm while moving the building materials, together with the binding agent, additive and liquid outwardly through the annular rows of beater paddles against impact surfaces of the beater paddles, the beater paddles enclosing a dihedral angle with respective tangential planes of the annular rows to activate the particles at a rising amplitude as they move through the annular rows of the beater paddles, and the annular rows of beater paddles having widths decreasing outwardly by 2% to 10% to activate the particles at a rising frequency.

A method of producing a multiphase liquid medium of immiscible components, such as an emulsion or a suspension, which comprises introducing the components at desired ratios in an apparatus comprising at least three concentrically arranged annular rows of beater paddles, counterrotating the annular rows of beater paddles about a common axis of rotation at a speed of rotation of 950 to 2800 rpm while moving the components outwardly through the annular rows of beater paddles against impact surfaces of the beater paddles, the beater paddles enclosing a dihedral angle with respective tangential planes of the annular rows to activate the components at a rising amplitude as they move through the annular rows of the beater paddles, and the annular rows of beater paddles having widths decreasing outwardly by 2% to 10% to activate the components at a rising frequency.

A method of treating a gas, which comprises the steps of injecting an absorptive medium into the gas to be treated, introducing the gas and the medium in an apparatus comprising at least three concentrically arranged annular rows of beater paddles, counterrotating the annular rows of beater paddles about a common axis of rotation at a speed of rotation of 900 to 3500 rpm while moving the gas and medium outwardly through the annular rows of beater paddles against impact surfaces of the beater paddles, the beater paddles enclosing a dihedral angle with respective tangential planes of the annular rows to activate the gas and medium at a rising amplitude as they move through the annular rows of the beater paddles, and the annular rows of beater paddles having widths decreasing outwardly by 2% to 10% to activate the gas and medium at a rising frequency.
