Technical Field
The invention relates to a continuous mixing system, which comprises two special screws that move linearly along their own axes and are also able to rotate about their own axes.
Background of the Invention
On worldwide scale, the continuous mixers are generally made in three different forms, namely the single-screw mixers, the single-screw mixers with linear movement in the direction of the screw axis, said linear movement being synchronous with a circular movement, and the double-screw mixers.
The aforementioned mixers have to be designed differently in order to be able to mix different materials. The reason is that their operating principle is suitable for varying only one or two parameters (number of revolutions, the extent of linear movement in the direction of the screw axis). This reduces the amount of mixing performed per unit time by the mixer and limits the fields where the mixers may be operated.
The mixing system according to the invention basically comprises two special screws, which move linearly along their own axes and are also able to rotate about their own axes.

Description of the Invention
The mixing system according to the invention basically comprises two special screws (2), which move linearly along their own axes and are also able to rotate about their own axes.
The manner of operation of the invention may be described as follows:
A special drive system moves two screws (2), which rotate at equal speeds and are placed into a sleeve (1) made in a way to suit the purpose, linearly (forward-backward) in a direction parallel to the axes of the screws.
Said screws (2) are, at the same time, able to rotate about their own axes, with the rotational movement and the linear (forward-backward) movement of the screws (2) being independent from one another. That is, these movements do not have to be synchronous.
With the mixing system according to the invention, it is possible to vary the following five parameters:
1- Number of revolutions of the screws (2): It may be varied in a manner independent from the linear movement in the direction of the axis of the screw (2). 2- Speed of the linear (forward-backward) movement along the direction of the axis of the screw (2): It may be varied in a manner independent from the direction and speed of rotation of the screws (2).
3- Amplitude of the. linear (forward-backward) movement along the direction of the axis of the screw (2): It may be varied in a manner independent from the direction and speed of rotation of the screws (2) and also independent from the speed of the linear (forward- backward) movement in the direction of the axis of the screw (2).
4- Phase difference of the linear (forward-backward) movement along the direction of the axis of the screw (2): It may be varied in a manner independent from the amplitude of the linear (forward-backward) movement along the direction of the axis of the screw (2), independent from the speed of the linear (forward-backward) movement in the direction of the axis of the screw (2), also independent from the direction and speed of rotation of the screws (2).
5- It is possible to stop the linear movement of any of the two screws (2) and to move the other screw in the linear direction (forward -backward).
Said characteristics of the invention provide the system with the ability of a very high rate of mixing and aiso with a wide field of operation without necessitating a different screw (2) design.
The technical description for the form of the screws (2) is as follows:
The threads (3) on the screws (2) enable the material to advance and to become compressed (Figure-3), while the profile shaped like a long gear enables a very well mixing for the material.
