The invention relates to the production of building materials, in particular, the molding of heat-insulating products from granules during their manufacture.

The purpose of the invention is to extend the technological capabilities of the installation, increase its productivity and improve the quality of products.

Figure 1 shows the installation, General view; figure 2 is the same, the view in the plan; on fig.Z - pressing device with a discharge mechanism; figure 4 is the same with the loading mechanism; figure 5 - the same with the molds.

The installation contains a stanitsa 1, on which a matrix 2 is formed, which forms a hollow with a bottom movable in vertical plane 3, rigidly connected to pneumatic cylinder 4, punch 5 moving up and down along guide racks 6 on which beam 7 is mounted with force pneumatic cylinder 8. The punch-20 initial formation of the cylindrical bore 5 is provided with a working member for the outer and inner diameters of the longitudinal side surfaces of the shell ends. The compression of a cylindrical article, made in the form of a wrap around: the ical and lateral surfaces that carry it around the perimeter and in the longitudinal section of the movable frame 9, excluding the machining of the movable frame 9, is at the top level picking and providing the volume of the matrix 2 granulator, condition - 25, the two operations in one - molding and processing. The molding of the products by compression using the matrix 2 with the movable bottom 3, the punch 5 and the movable frame 9 makes it possible to achieve an equal cross section and adherence to the geometric shape of the product.

After crimping, the punch 5 rises and the molded product is removed from the matrix 2 by means of a bottom movable 3 in a vertical plane, which pushes the product. The resulting products are stacked on the shelves using the loading mechanism 17, alternately filling a bulk lattice cassette 18. Filled with the lattice loading mechanism 17, the cassette 18 is guided into a dryer for curing with a movable stop and mounted with accessories. Cassettes 18 with products that have passed the possibility of free passage of the stop over heat treatment are mounted on the die at the moment of the upper position in the vertical plane of its movable bottom 3. At a distance multiple of the overall dimensions of the trellis cassette 18, the mechanism 19 is mounted at the same level with the die 2 removing items from cassettes. The installation is also equipped with mechanized posts 20 and 21 for cassette loading and unloading of products and pipelines 22 and 23 for feeding the mixture and draining the liquid. The installation works as follows. The prepared raw material mixture through conduit 22 falls from the storage compartment to a vertical precipitation centrifuge 10, which acts as a granulator-agglomerator, where the mixture is dehydrated, and

from a centrifugal centrifuge 10 with a screw 11 for discharging sediment connected in the lower direction and coaxially with an aero fountain dryer 12, inside which nozzle nozzles 13 are installed in the lower part, and dryer 12 is connected in the upper part to the granule accumulator 14. In this case, The lower part of the accumulator of granules 14 has a discharging device 15, acting in a horizontal plane for loading granules of the dosing container 16 and mounted with the possibility of free passage of the dosing container 16 above the die 2 and the punch 5 at the moment they are ema. On the frame 1 is also located the mechanism 17 of loading products in the cassette 18, equipped with
