    consecutive layers of spread solidified product Tl. However, this device is not characterized by high productivity, since it is difficult to maintain a uniform layer when working on installations with a significant diameter (less than 1 m). The gas flow required for operation is responsible for transporting large grains to the dust collecting cyclones. Consequently, there is an increased degree of recycling. There is also the danger of the layer being blocked by the formation of too large granules. The goal of doom is to increase productivity. This goal is achieved by the fact that in a device for granulating and / or coating granules with a casing in a fluffing layer comprising a vertical cylindrical chamber with a lower conical part, a coaxial pipeline for gas water connected to a small base of the conical part, and a device for removing granules cylindrical the chamber is equipped with a liaicHoifflbiM base and a conical washer installed in its lower part; it is conical, and a part is at least partially located inside the cylindrical chamber above the conical part so that Conic washer and the part annular gap is formed. This reduces the entrainment of the product of the CC chamber at high gas flow rates and ensures a uniform removal of the obtained granules, which leads to an increase in the productivity of the installation. The drawing shows schematically an installation for transfusing and / or along the "LITTLE of granules with a shell, longitudinal section. The installation holds the tsipindric chamber 1 with an inclined base 2. This base is partially intersected by the conical part 3, the large upper base of which is located inside the cylindrical chamber 1, and the lower small base may be located inside the cylindrical chamber, partially inside and almost outside: Scheduled drawing, completely. Above the nightmare part 3 is a conical washer 4, also having a truncated cone, attached to the wall of the cylindrical chamber I, so that between its lower edge and the upper edge of the conical part 3 remains (ring-shaped casing 5. The small base of the conical part 3 is connected to the feed gas 1u1 pipe line) with gadfly 6, ending with a truncated cone. The connection between the small base of the conical part 3 and the pipe 6 is made through the cylindrical part 7. This cylindrical part can be liquidated, then the connection between the gas pipe-tip 6 and the conical part 3 forms a confusion of the diffusion system. The atomizer 8 is located near the plane of the small Base. The washer 4 and the conic part 3 divide the cylindrical chamber 1 into the upper half 9 and the lower half Y. In the lower part of the chamber there is a pipe II for removing the obtained granules; In the upper half 9, there is a pipe-to-water pipe 12 for gas release. The pellets are recycled through conduit 13, located above and / or below the conical washer 4. The installation operates as follows. A gas stream is introduced through line 6 which supports; granules in the form of a flowing layer. The circulation of granules in the sprayed layer is shown schematically in the drawing by arrows. It can be seen that the main part of the layer is located in the conical part 3 and that a single central stream or geyser 15) collides into the upper half 9 of the cylindrical chamber 1. Particles of this jet are generated into the layer by means of a conical washer 4. The upper half of the 9 cylindrical chamber has a larger diameter than the large base of the conical part 3, the gas flow щ of the schionic in the upper half 9, slows down considerably. Consequently, the idle flow through the gas flow is significantly reduced. The granules continuously extend beyond the edge of the annular gap 5 above the large base of the conical part 3. They then fall into the lower half of the Cylindrical chamber 1. In the proposed installation, the base 2 is formed by solid solid and the particles are rolled down from the top for 15) to the discharge pipeline 11. The base can also be formed by means of a sieve which carries out a fairing treatment. The discharged granules are sieved in a known manner to separate
    commodity from small and crumbly particles, then, after grinding, small and large particles are recycled. This rectification is carried out by means of a piping 13.
    Tests are carried out in a glass installation with a diameter of 9.7 m. These tests are performed with a PHI of the same conditions of flow, temperature, pressure in the sprayer position.
    The table shows the granulometric composition of the resulting shchuduk in the case of a known granulator with a radial output of 1 product according to what is known in the outlet through a concentric I overflow through the edges in accordance with the content of the product.

    Famous Proposal As can be seen from the table, the output of u) of the product (fraction 2-4.75 mm) is increased to 8O% Irk using the heated installation. In addition, the conical part, completely independent of the cylindrical chamber, is easily replaced, i.e. installation maintenance is also facilitated. It is possible to easily set up an installation for processing various products, installing conical parts with different angle of taper.
