which are interconnected by a hinge 16.

The gypsum mixer 3 is mounted with the possibility of rotation in a horizontal plane at an angle of 70 °, which makes it possible to evenly lay the gypsum concrete mixture over the entire width of the product.

Behind the drive drum 9 above the lower forming tape 5 across its movement, at the exit point from under the upper tape, a trowel 17 is installed. It is made in the form of a closed closed drive chain organ 18, consisting of two branches and mounted on frame 19.o

On the branches of the chains x, alternately with a certain step, flexible spatulas 20, 21 of different widths are fixed, and the width of some spatulas exceeds the width of others. The spatulas 20, 21 are fixed with the possibility of their rotation relative to the longitudinal 20 axis of the lower forming tape 5 at an angle of up to 45 ° in different directions. e

The inclined conveyor 22 is provided with a horizontal section 23 mounted in its lower part 25

The device for grinding and transporting waste to the gypsum mixer 3 is made up of three crushers 26-28 connected by horizontally transverse conveyors 24, 25 for various crushing fractions. Moreover, the conveyors 24 and 25 are located across the movement of the forming tape 5.

The first crusher 26 is mounted under the forming tape 5 in the area of the drive drum 35. The receiving part 29 of the housing 30 of the first crusher 26 is made to the width of the forming tape 5, and its output part 31 is located above the first horizontally transverse conveyor 24 along its 40 movement. The housing 30 of the first crusher 26 is equipped with two combs of large crushing 32 and 33, and its rotor 34 has knives 35. which are installed along two closed helical lines with a diametrical arrangement of knives in each, while the knives of each subsequent step of the helical lines are offset 12 °.

The first horizontally transverse 50 conveyor 24 is equipped with an automatic ejector 36 (known design).

The receiving part 37 of the casing 38 of the second crusher 27 is located under the first horizontally transverse conveyor 55 25, and the output part 39 is located above the horizontal section 23 of the inclined conveyor 22. The casing 38 of the second crusher 27 is equipped with two combs 40,41 for medium crushing.

The construction of the third crusher 28 is similar to that of the crusher 27. The receiving part 42 of the housing 43 of the third crusher 28 is located under the upper part of the inclined conveyor 22, and its output part 44 is located above the second horizontally transverse conveyor 25. The housing 43 is equipped with two combs 45, 46 for fine crushing . Moreover, the receiving parts 37,42 and the output parts 39, 44 of the crushers 27, 28 are made respectively for the width of the conveyors 24, 25.

The rotors 47, 48 of the second 27 and tre.ovgo 28 crushers for medium and fine crushing have knives 49, 50, which are installed along two open helical lines with a diametrical arrangement of knives in each, while the knives of each subsequent step of the helical lines are shifted by 12 °.

The horizontal-transverse conveyor 25 is made with an inclined tray 51 located on the housing of the material guide 52 of the gypsum mixer 3..-.-

Installation for the manufacture of gypsum concrete panels works as follows. . ; .

Frames of future panels are laid on the receiving table 1, docking them end to end tightly to each other. From the receiving table, the carcasses are fed at a speed synchronous with the speed of the lower forming tape 5 to the lower forming tape, which feeds them into the laying and molding zone of the gypsum concrete. .

The gypsum mixer 3 of continuous operation, turning (reciprocating) in a horizontal plane, makes it possible to evenly lay the gypsum concrete mixture over the entire width of the panel. The frame filled with gypsum concrete enters under the block of crimp-gauge rollers 10, covered by the upper forming tape 6. The crimp-gauge rollers are set to a predetermined panel thickness. Under crimp-gauge rollers, the gypsum concrete panel is calibrated and compacted. Periodically, a forming device 53 (vib-4 robalka) is included in the operation together with crimping and calibrating rollers. ......

After the molded panels exit from under the upper forming tape 6, the upper surface of the panel is finished with a trowel 17.

Putty mortar is supplied to the surface of the panel by known methods.

Surface mashing is carried out with flexible trowels 20,21, the width of some of which exceeds the width of the others, fixed alternately under different

adjustable angles of attack with the possibility of their rotation relative to the longitudinal axis of the lower forming belt up to 45 °, which allows the surface to be rubbed in two directions. This is due to the fact that the narrow spatulas 21 are fixed with an angle of attack in the direction of movement of the panel (forming tape), and the wide spatulas 22 are mounted and secured with an angle of attack against the movement of the panel. When the ratio of the speeds of the spatulas and the forming tape is 1: 6, the wide spatulas 20 pick up the solution coming out from under the spatulas and wipe the surface in the opposite direction.

After grouting the surface, the panel enters the overtaking conveyor 12 with the speed of the forming belt 5, from where it moves to the tilter 11 with a higher (overtaking) speed. The tilting machine rotates the panel at an angle of 85 °, then it is removed and transported by a cassette trolley to the heat treatment chamber.

The gypsum concrete waste generated during the manufacture of the panels is discharged from the lower forming tape 5 in the envelope zone of the drive drum 7 to the first crusher 26, where waste is crushed into large fractions.

From the first crusher 26, the pre-shredded waste is transferred to the first horizontally transverse conveyor 24, which feeds it to the second crusher 27. If more waste is accumulated on the first conveyor 24, an automatic ejector 36 is activated, through which the waste concrete is dumped and subsequently disposed of special devices.

In the second crusher 27, large gypsum concrete waste is crushed into middle fractions, which, through the outlet, fall into the horizontal section 23 of the inclined conveyor 22 and are transferred to the third crusher 28 to obtain a fine fraction. Then, the crushed waste through the outlet part enters the second horizontally transverse conveyor 25 and through the inclined tray 51 fall into the gypsum-concrete mixer 3.

In order to improve the convenience of servicing the installation, namely the freewheeling conveyor, the first and second crushers, as well as the inclined conveyor, when they are inspected and repaired, the rotary part 15 leans out on a hinge, allowing easy access to these mechanisms.

This technical solution makes it possible to improve the quality of the manufactured panels and to reduce the consumption of gypsum concrete mixture due to the production of fine fractions of waste crushing, as well as to improve the quality of the finish on the outer surfaces of the panels.
