SU1206109A1 - Activating mixer - Google Patents

Description

The invention relates to devices for the preparation of concrete and similar mixtures of finely divided materials.

The purpose of the invention is to increase productivity due to the intensification of the activation process.

Figure 1 shows the mixer-activator, a general view; figure 2 shows a disk with rows of beats and radial re-, ber, top view.

The activator mixer contains a disk 1 with radial ribs 2, bilami 3, a cylindrical body 4 with an annular recess 5 and a protective cover 6 forming an annular channel 7 with the body for unloading lumpy or uncrushable material 8 and the unloading nipple 9.

The lower edge of the recess 5 is located in the plane of the surface of the disk 1 with the beams 3. The beater 3 and the radial ribs 2 are located along the inner and outer concentric circumferences. The radial ribs 2 are filled with the upper edges beveled to the drive shaft and parallel adjacent side edges forming the separating conical surface that

Mixer-activator works as follows.

The stowing mixture from the loading nozzle 8 falls on the rotating disk 1 and, accelerating on its surface, passes into the gaps between the radial ribs 2, while metal objects or stones

0 larger than the width of the gap between the radial ribs 2 move along their inclined edges under the action of centrifugal forces and are unloaded from the mixer through the channel 7. Mix, pass

the final mixing and activation of the mixture takes place. The finished mixture is squeezed out of the slit of the mixture re-entering it and is discharged from the mixer through pipe 9.
