Abstract

This invention relates to granulation for the production of lightweight aggregates of concrete. The purpose of the invention is to improve the quality of the granules by eliminating the distortion of their shape. The granulator contains the former (F) 1, the pressing element 3 adjacent to the F1 surface, and the means 6 for injection. Moreover, the line of contact of the pressing element is displaced from the plane passing through the axis of rotation of the means for injecting and its line of contact with F 1 towards the loading hopper. When F 1 moves above the pressing element 3, a part of the material goes into the forming 2 from the inside of the former 1, up to this point, is pressed into the forming holes again. At the same time, the material is compacted on the other side of F 1 by pressing pressure. Upon further movement of the F1, the sealing material is continuously sg removed by the pressure of the new volume of the material to be formed. 5 il. (L

The invention relates to mechanical engineering and can be used in the industrial construction materials, in particular, in the formation of raw granules from viscous and plastics for the production of lightweight aggregates of concrete.

The purpose of the invention is to improve the quality of the granules by eliminating the distortion of their shape.

FIG. 1 shows the proposed granulator, general view; Fig. 2 shows a granulator with two shapers; fig. 3 - the same, with a form-maker made in the form of a perforated disk; FIG. 4 is a view A of FIG. 3; figure 5 - shaper with press cim element in the form of a shoe with a curved surface.

The granulator comprises a drive-connected perforated die 1 with forming holes 2, made in the form of a roll or a disk, located near the surface of the die formers on the outlet side of the material, the pressing element 3 mounted with the supports 4, and the knife 5, means 6 for pumping , hopper 7 and inclined tray 8 for finished product. The pressing element can be made either in the form of a cylindrical roller (figure 1 - 3) or a shoe with a curved surface - (figure 5). The contact line of the pressing element 3 with the shaper 1 is displaced relative to the plane passing through the axis of rotation of the means 6 for injection and its contact line with the shaper 1 towards the loading hopper 7. At the same time, the second shaper (figure 2).

The granulator operates as follows.

The material to be processed from the feed hopper 7 is captured by means of 6 for injection and shaper 1, rotates from the drive towards each other, and is injected into the forming holes 2 of the shaper. At the same time, a part of the material, not more than 10-20% of the volume of the formed granules, leaves the opening

2 from the inside of the shaper 1 in the form of short cylindrical rods with a length of 2-4 mm. As the die 1 moves over the pressing element 3, the rods of the material are pressed into the forming holes 2 of the die 1 again, sealing the material. At the same time, the material is compacted on the other side of the die former 1 due to the pressing pressure.

Upon further movement of the former, the compacted material is continuously pressed with the pressure of a new volume of the formed material. The finished granules are cut by the knife 5 and fed into the inclined tray 8. When the pressing element 3 is made in the form of a shoe with a curvilinear surface, the formed granules are rolled around due to their contact with the fixed curvilinear surface of the shoe and the forming former 1, resulting in spherical granules coefficient of form, close to one. When making the pressing element 3 in the form of a cylindrical roller, due to the continuous reduction of the volume of the formable material and the continuous increase in the free space on the output side of the material, the formed granules will have the same limited length and regular shape.

Offered construction of granules -; torus provides the release of homogeneous; in size and shape of granules during the processing of various materials into a plastic material for the production of lightweight aggregates of concrete.
