The purpose of the invention is to increase the quality of granules and reduce energy consumption.

This goal is achieved by the fact that, in a granulating device, tea containing "5 housing with installed fine lattices and camera-forming filler lattices, the size of which decreases in: the output section, as well as crushed. I do not grind this section, knife, part The skirt, adjacent to the filler gratings, is made in multiples of one, the relative size of the holes of the hole and the last grating does not exceed the parts of the shchek are located in the chambers so that the gap between the radial edge of each screw of the screw and the adjacent n ::; astyu f Ljerka lattice structure: gYa8 No more than 40% of the thickness of the dies resheg; and lr1 /; the gaps are reduced in the following:, n1 of the output section, and the grinding is: yu; the scab knife: "is individual at: / c,.

Bypassing the auger with multiple inputs from at least three approaches allows you to create an effective pressure on the original source, which is necessary for pushing: iSHWB through the Dies with small openings .ifjMiA (2-5 mm,

In a three-way auger, the movement proceeds more evenly along the isg; th interlobular canalism and expired; ROAU: a hundred cedez to a spinneur, thank the oiuli are equal in size,

The flux screws installed by Si for each chamera create the necessary vpoR8H:., Power-iHOCTii of the material to flow through the last spinneret with holes of small diameter — 2-2.5 mm, which provide the required particle size distribution of the finished product.

Since the openings of the first and last gratings differ by no more than four times, the best optimal conditions for the kneading of the product are created. Based on the conducted granulation experiments, an improvement in the granule structure was found.

Zazrr between the radial edge of the auger blade and the adjacent surface of the draw plate; : can not be increased by more than 40% of the thickness of the draw plate, as it increases significantly for the mass through the spin grid (tested experimentally by means of an actual model using real products). The growth is non-linear, due to the specifics of the transfer of force s d to a non-Newtonian class of interfering medium. For the same reason, it means that 8. POWER grows and consumes POWER; supplied to the auger.

To achieve an opt1 / 1 minimum granulation composition at the exit from the granulator, an appropriate rotation frequency of the knife, cutting the extrudate into pieces, is necessary. Since a change in the frequency of rotation of the screw or a change in the number of blades of the knife (in the case of the prototype) could not achieve the desired result, in the proposed device the knife is equipped with an individual drive.

FIG. 1 shows a pelletizing device, a section; FIG. 2 is a diagram of the forces acting on the moving material.

In the housing 1 with a loading nozzle (bunker) 2, a screw 3 is mounted on the support assembly, rotated by an electromechanical drive (not shown). At the end of the screw 3 in the zone adjacent to the draw plate 5, on the same shaft with the screw 3 there is a three-way screw 4, the main parameters of which are determined experimentally using a specific raw material,

Casing 6 and 7 are fastened to housing 1 by means of easily-dismounting elements, between which a filter plate is installed, and a filter plate is attached to the end of crown 7 7. Three-way are placed in the working cavities of chambers formed by bars 6, 7 and dies 5.8.9. screws 10 and 11, similar to element 4 and mounted on a single shaft with screw 3. The gaps between the radial edge of each blade of the screws 4,10,11 m spunbits 5, 8, 9 make up no more than 40% of the thickness of the grid and decrease 2 1 . The diameters of the first 5 and last 9 gratings differ by no more than four times. The rotation of the shaft to the screw 3 and the three-way screws 4, 10, 11 is transmitted by the key connection. It is experimentally established that the number of chambers containing .x three-way auger should not be less than three. as in the case it is not possible to obtain, the mass of the desired plasticity. The knife 12 is installed on the outer side of the die 9 SI has an individual drive 13 zrasta-zni with a frequency (20-30) p. where n is the screw rotation frequency.

The device works as follows.

The initial mass of gfy of the required humidity and temperature is supplied to the loading nozzle (bunker) .2 and rotating, m 3 moves in the direction of the first filler grating 5. At the same time, the mass is compacted and partially heated. Further, the product (material) with a three-way screw 4 is forced through the first draw plate 5 into the second chamber. The process of moving the material through the second and third gratings 8, 9 is similar and is carried out by rotating screws 10, 11 placed in chambers b, 7. As the next spuning grating passes, the degree of plasticity of the material ta increases and when the third grid passes through, the structural changes in the material and its plasticity achieve the required values to achieve the desired quality of finished granules. In this case, the separation (crushing) of the outgoing holes of the formed wiring harnesses is carried out by a fast-growing knife 12.
