The discharge device 6 at the outlet of the regenerator 5 serves to unload the regenerate for cooling it in air; then he using the feed line 7 enters the chopper 8 of the regenerated mass; the second dispenser 9 and the loading device 10 are designed to supply sand and

dye into the mixer And, connected by the input feed line 12 with the grinder 8, and the output feed line 13 with a horizontal reactor 14 having three successive different-temperature zones, equipped with heating elements and rotatably mounted general shaft 15 with asymmetrically arranged blades; at the outlet of the reactor 14 there is a weight batcher 16 connected to the forming device 17, made in the form of a detachable mold, and a drying table 18. The heating elements of the regenerator 5 and reactor 13 are not shown and are not indicated in the drawing. There are drive devices for the two-flow operation of all nodes (not shown and not indicated in the drawing).

As grinders can be used, in particular, crushed drum type BSi.

The technological line for the production of polymer finishing materials works as follows.

According to the technological process for the production of polymer tiles and tiles, the following raw materials are used: fine sand without stones, lumps of clay, etc., soft plastic (LDPE, HDPE, etc.), hard plastic (ABS, polystyrene, PET, etc.) and dye (iron oxide pigment).

Upon receipt of soft to hard waste polymers at the production site, they are weighed by a weighing dispenser 1 in a ratio of 1: 1, transported to a loading device 2 on a trolley, loaded and fed to a grinder 3, where they are crushed to a fraction of 1- (15-25) mm. Then, the full mass of crushed soft and hard plastics is fed through a supply line 4 to a regenerator — extruder 5 for polymer regeneration. Screw extruder 5 is made in a cylindrical body of two

between each other sections of different diameters, each of which is equipped with its own heating element and has a different temperature. The diameter of the first section is greater than the diameter of the second; auger is common. The frequency of rotting: the screw of the EtEstruder is 15 rpm; the regeneration process is carried out continuously, the required amount of mass of plastics is constantly added. The temperature in the first section is about 200, the temperature of the mass at the outlet of the Shnews extruder 5 reaches 165-175 ° C. The mixture of regenerated polymers with ingots of a fraction of 1-40 to 1-70 mm is discharged from the extruder through an unloading device 6, cools in air, then the regenerate is fed through a charging device 7 to the grinder 8, where it is crushed again to the fraction of NOmm. From the exit of the grinder 8, the crushed regenerate is fed through the feed; the 12th line is fed into the mixer 11, where sand and dye are also fed through the weight doser 9 and the loading device 10 in proportions, respectively: regenerated plastic 4.5 kg, sand 15 kg, dye 120 -150 g. From the mixer 11, the thoroughly mixed mass flows through the feed line 13 to the reactor 14. In the first zone of the reactor 14, the temperature is brought to 210CH1 using the heating element, in the second zone with the help of another heating element, to a temperature of 250 ° C, in the third zone - order BSA 190C. Due to the original design of the rotating shaft 15, which has asymmetrically located blades, the mass passes through the different temperature zones of the reactor 14 at different speeds, which allows to obtain the mass of the desired consistency in one pass. The rotation speed of the shaft 15 is 18.5 rpm The required amount of mass for molding into the finished product is determined using a weight batcher 16. The mass temperature at the outlet of the reactor 14 is then the heated mass in the amount of 2 kg 100 g from the reactor 14 is placed in

mold 17, where it is molded for 3 & seconds. During operation, the temperature of the water cooling the upper mold 17 should be 80 ° C, the temperature of the lower mold 17 should be minimal. After the molding process, the tile or tile is placed on the drying table 18, where, under the influence of ambient air, the product finally cools down and fixes. If necessary, the tile is cleaned from flashing, after which it is folded into packs of 9 pcs. In comparison with the prototype of the claimed production line has wider functionality.
