The core technology is the combination in one working cycle of the whole process of preparation of the moulding mixture, i.e., increasing its plastic properties, uniformity of composition, uniform distribution therein of moisture, the destruction of its natural structure, mixing clay with solid and liquid additives that are performed in the same machine the tapered homogenizer mixer [3]

For the preparation of solid and liquid additives with astringent properties, use the installation for the preparation of ECCU. ECCU is added to the clay in an amount of 10 to 50% by weight of clay is neobreznye melhuse - abrasive elements in the working area, and the use of alkaline water with a pH of 10.5 to 11.5 as thinning supplements. The method of obtaining the ECCU is in fine grinding vysokoglinozemistykh materials (e.g. quartz sand, containing SiO296%) using alkaline water as a thinning of the additive homogenizer-activator continuous-flow actions with fusiform melhuse-abrasive elements in the working area and the subsequent stabilization of the ECCU in the stabilizer drum type.

The drawing shows a production line for the manufacture of tiles.

Production line includes warehouse-bunker 1 clay hopper 2 quartz sand, capacity 3 to alkaline water dispensers, clay 4 and sand 5 supplied to the tapered homogenizer-mixer 11, dispensers sand 6 and water 7, used to prepare the ECCU, the homogenizer-activator 8 having a feed screw and a conical grinder with spindle melhuse - abrasive elements in the working area, the stabilizer 9 ECCU, the dispenser 10 ECCU, the tapered homogenizer-mixer 11 with the feed auger and cone crusher, screw press 12, the machine 13 tile cutting tape, installation 14 heat treatment of shingles in the microwave field currents player 16 and warehouse 17 of the finished product.

The tapered homogenizer-mixer 11 is the preparation of the molding of the ceramic material, which is continuously fed into the tape screw press 12.

The extruding pressure of 12 ceramic tape is cut into individual tiles machine-cutter 13, which are received at the receiving belt conveyor thermal installation 14 heat treatment in a microwave field currents microwave oven, transforming into a conveyor high temperature zone, moving synchronously receiving conveyor, where the final drying and firing. When exiting the installation of heat treatment shingles are served in the cooler 15, after which the machine-compacting machine 16 are packaged and sent to the storage 17 of the finished product.

Predlozhenijami properties of any of the clays. This is achieved by using ECCU.

The use of tapered homogenizer-activator continuous flow of steps in a process line for the production of ceramic tiles allows to simplify considerably the known manufacturing process ECCU based on fine grinding in ball mills, thereby providing economical, technological and environmental cleanliness. The application of the ECCU in molding a ceramic mixture ensures a significant increase in strength characteristics of the final product, the use of clay with low ceramic properties, the use of different non-deficient additives to the clay, such as sand, waste, etc. It is possible to drastically intensify technological cycles at various stages and, ultimately, significantly reduce the time the entire production process.

The proposed technological line for production of ceramic tiles do not require large production areas and can be located in the premises of easy-to-assemble design, because it consists of a small amount of equipment and tunnel installation heat treatment of products in a microwave field currents microwave them is egati.

The application of the ECCU as modifying additives allows you to get shingles with high density, low shrinkage, high compressive strength and Flexural strength. The application of the ECCU for modification of the molding mixture reduces the time of drying and firing at 10.15 time compared to the traditional way. Application ECCU allows a wide range to adjust the properties themselves ceramics and the finished tile.

The use of a homogenizer-mixer for the preparation of the molding material, which is carried out in a closed environment with a humidity conditions, eliminates the pylevydeleniem and unsanitary conditions. The process homogenizator processing moulding mixture does not pereseleniu solid components, eliminates the stage of aging of the mixture before forming.

Use for heat treatment of products installation microwave shortens the cycle thermal treatment of products in 10 times, improves the quality of the finished tile, allows you to get cost-effective and cleaner production.
