Inventia se refera la tehnologia de producere a materialelor de constructie si poate fi utilizata la prepararea amestecurilor uscate pentru tencuire,zidarie si alte tipuri de lucrari de constructie.Linia tehnologica include un buncar pentru incarcarea deseurilor (1) cu un afanator (2) amplasat inpartea lui de jos, un transportor cu banda (3), care transmite deseurile afanate, un ciur (4) ce include un bloc de site, care sunt instalate in ordinea descrescatoare a dimensiunilor celulelor sitelor, un buncar de stocare a deseurilor cernute (5), o instalatie pentru amestecarea componentilor amestecului uscat, care include un buncar de incarcare a componentilor amestecului (13), amplasat sub acesta, un malaxor a componentilor amestecului (17), si un buncar de stocare a amestecului uscat obtinut (19). Noutatea consta in aceea ca linia include suplimentar, amplasata intre buncarul de stocare a deseurilor cernute (5) si instalatia de amestecare a componentilor amestecului uscat, o instalatie pentru uscarea deseurilor, care include doua dispozitive pentru uscarea continua (6 si 9), unite printr-un racord (8) si amplasate unul deasupra altuia, fiecare fiind dotat cu un organ de lucru in forma de snec. Buncarul de stocare a deseurilor cernute (5) este instalat deasupra dispozitivului superior (6), iar sub cel inferior (9) este amplasatun snec-transportor (10), care orienteaza deseurile uscate la snecul de alimentare a buncarului de incarcare (13) a instalatiei de amestecare a componentilor amestecului. Buncarul de incarcare (13) este executat sectionat, una dintre sectiile caruiaeste legata cu snecul de alimentare cu deseuri uscate (11), celelalte - cu snecurile de alimentare cu cel putin un liant (14) si nisip (15). Fiecare sectie este dotata cu dispozitive de dozare a componentilor (16), amplasate in partile lor de jos. Deasupra buncarului (13) este montata o sita vibratoare (12), care include site separate, amplasate deasupra fiecarei sectii a buncarului (13). Malaxorul componentilor amestecului (17) este legat cu buncarul de stocare a amestecului uscat obtinut (19) printr-un transportor elicoidal (18). Dispozitivul pentru uscarea continua a materialelor disperseinclude un corp cilindric amplasat orizontal, cu o gura de alimentare si una de evacuare, in interiorul caruia este montat un organ de lucru, legat cu mecanismul de actionare a rotatiei lui, peretelecorpului este executat dublu si include mantaua exterioara si cea interioara, cavitatea formata dintre ele este umpluta cu purtator de caldura, in partea de sus a corpului este amplasat un sesizor termic, in mantaua exterioara este executat un orificiu pentru debitarea purtatorului de caldura. Noutatea consta in aceea ca organul de lucru este executat in forma de snec. In calitate de purtator de caldura este utilizat aburul de apa. De-a lungul cavitatii inelare dintre mantalele exterioara si interioara a corpului sunt amplasate diafragme executate in forma de sectoare inelare, amplasate diametral, inThe invention relates to the technology for the production of construction materials and can be used in the preparation of dry mixtures for plastering, masonry and other types of construction works. The technological line includes a bunker for loading waste (1) with a sender (2) located at the side. from below, a conveyor belt (3), which transmits the wastes, a sieve (4) that includes a block of sites, which are installed in descending order of the size of the cells of the sieves, a storage bunker of the sieved waste (5) , an installation for mixing the components of the dry mixture, which includes a loading hopper of the components of the mixture (13), located below it, a mixer of the components of the mixture (17), and a bunker for storing the dry mixture obtained (19). The novelty consists in that the line includes additionally, located between the storage bin of the sieved waste (5) and the installation of mixing the components of the dry mixture, an installation for drying the waste, which includes two devices for continuous drying (6 and 9), joined by - a fitting (8) and placed one above the other, each being equipped with a workpiece in the form of a screw. The sieve waste storage bunker (5) is installed above the upper device (6), and below the lower one (9) is located a snake-conveyor (10), which directs the dry waste to the feed hopper of the loading hopper (13). mixing installation of the components of the mixture. The loading hopper (13) is executed sectioned, one of the sections linked to the dry waste feed spout (11), the other - to the feed screws with at least one binder (14) and sand (15). Each section is equipped with devices for dosing the components (16), located in their lower parts. Above the bunker (13) is mounted a vibrating screen (12), which includes separate sieves, located above each section of the bunker (13). The mixer of the mixture components (17) is connected to the storage tank of the dry mixture obtained (19) by a helical conveyor (18). The device for the continuous drying of the dispersed materials includes a cylindrical body placed horizontally, with a feeding mouth and an outlet, inside which is mounted a working member, connected with the mechanism of actuating its rotation, the wall is executed double and includes the outer sheath and the inner one, the cavity formed between them is filled with a heat carrier, in the upper part of the body is placed a thermal detector, in the outer sheath is executed an orifice for cutting the heat carrier. The novelty consists in that the working body is executed in the form of a screw. As a heat carrier, water vapor is used. Along the annular cavity between the outer and inner layers of the body are placed diaphragms executed in the form of ring sectors, placed diametrically, in
