This complex allows to produce a wide range of compact construction materials as cement and silicate technology with virtually no waste that is most beneficial to environmental surroundings the place of production.

The invention consists in the following.

The proposed processing facility manufactures concrete products cement and silicate technology. It was motivate various construction materials. The necessity of using lime binders leads to the existence of storage tanks for them, as well as host to grind them, and for compact placement of equipment on a vertical scheme is expedient to bring the structural members to each other, i.e., to have them the most flexibility in the layout diagram of the complex. Concentric location of storage tanks relative to the hopper allows in the most simple way to implement the transportation and industrial wiring materials for technological position.

A more rational design is also performing the forming of the site in the form of an annular rotary conveyor. Thanks to the mobile installation of the faucet directly above the rotary conveyor of the possibility of a significant reduction of time for preparation and distribution of the concrete mixture for forming the node.

Order individual seals concrete mixes visitors each product technology post pipeline, where the laying of the concrete mixture, the vibrating plate has air cushion. In addition, the use of the vibrating plate, air cushion allows wie allows 4-5 times to reduce the production area, and construction volume placed in it equipment. The proposed processing facility can be commissioned within 1.5-2 months.

Technological complex (Fig. 1-3) for the production of the compact construction of concrete products contains means for receiving and supply of aggregates performed in the form of a gripper of the gripper 1 and the skip hoist 2 which move material using the rotary hopper 3 into the feed hopper 4. Feed binder, cement and lime in the feed hopper 4 is made by means of the jet pump 5 through the piping system. To use the full resource of the pump 5 is made movable. Feed hopper 4 is equipped with dispensers 6 performing strictly dosed supply of the components of the concrete mixture to the mixer 7 with forced hydrodynamic mixing of the concrete mix, movably installed on the trolley 8 directly above the forming knot made in the form of an annular rotary conveyor 9, the I technological cycle operation for the manufacture of products. One of the posts, which is laying and compaction of the concrete mix, equipped with a vibrating plate 11 air cushion.

Given the fact that the complex is intended for the use of silicate technology, it has a node for grinding lime binders and sludge placed near the mixer 7. It consists of mill 12 dry grinding and mill 13 wet grinding. Line dry grinding includes a tank 14 for the binding and the jet pump 15. Line wet grinding apparatus includes 16 with a mixing device (not labeled) and a pump 17 for supplying slurry. Processed in the mill 12 material (semi-finished) is sent to the storage tank 18, concentric (Fig.4) located relative to the hopper 4. At the same time in the tank 18 is supplied cement and lime from motor vehicles to create a linefill. Processed in the mill 13, the slurry is sent through pipes directly to the mixer 7. All of the above nodes and elements placed in it by the vertical schema.

Technological complex, made in collapsible variant works as follows.

On the construction site, vibramy grapple 1 and the skip hoist 2 placeholders are served in the feed hopper 4, where at the same time, the jet pump 5 is pneumatically moves binder, cement and lime.

When using cement technology in the mixer 7 are dosed specified components from the feed bins and brought it to a certain consistency of the concrete mix. Then with the help of truck 8 mixer 7 is moved to the conveyor 9 and outputs the prepared concrete mixture into the form of post-laying and compaction of concrete. In the process of compaction of the concrete form raised on 3-4 cm relative to the rotor to form an air cushion that helps to isolate the action of vibration on the entire pipeline. The conveyor 9 (Fig.5) stepper drive mechanism (not shown) performs a synchronous movement of all technological posts 10 depending on the operation for the manufacture of products. Heat treatment of the products is done on the same conveyor after all operations with molded product (dotted positions of Fig. 5). After all operations are finished molded construction product hoisting mechanism (not shown) is moved to the place of its storage.

When using silicate technology the entire production cycle of the products is identical to the above, I mill 12 dry grinding, and in the manufacture of aerated concrete work, both mill 12 and 13 dry and wet grinding. The dosage of the components (sand, lime, water) carry out the screw feeder 19. Binder obtained in the mill 12, a jet pump 15 is supplied to the storage capacitor 18, and thence into the feed hopper 4.

In the mill 13 components (sand and water) are fed through the screw feeder 19 and the tank 20. Formed in the mill 13 sludge by means of a pump 17 is supplied to the apparatus 16, which is constantly mixed and dosed in the future in the mixer 7. Optionally, the mixer 7 of the tools 21 are dosed additives, creating a mesh of the concrete structure.
