ABSTRACT:

BACKGROUND OF THE INVENTION.
Specifically, though not exclusively, the invention is useful for mixing a mixture of solid loose materials, in powder or granular form, which may be mixed with a liquid.
Reference is particularly made to a mixer comprising a mixing chamber, having at least one inlet and one outlet for the material, internally of which chamber there is a rotor shaft bearing a plurality of radial blades for agitating the material.
1. Technical Field of the Invention
A mixer of this type is already known, in which the blades are normally arranged coaxially about a rotating shaft and extend radially to the shaft.
2. Prior Art
Known mixers of the above type are susceptible to improvement both in terms of homogenization of the mixture obtained and in terms of operative speed.
OBJECT OF THE INVENTION
The main aim of the present invention is to provide a mixer by means of which a much more homogeneous mixture can be obtained and faster than with known-type mixers.
An advantage of the invention is that it provides a mixer which is constructionally simple and economical.
A further advantage is that a mixer is obtained which can provide a high degree of homogenization of the various components of the mixture, with a relatively low energy consumption.
A further advantage is that the invention provides a mixer with short axial length and being therefore relatively small.
SUMMARY OF THE INVENTION
The mixer of the invention comprises a mixing chamber, having at least one inlet and one outlet for the material, internally of which chamber there is a rotor shaft bearing a plurality of radial blades for agitating the material.
