Raw materials:
(1) Nonwoven geotextile (width≥5000mm.)
(2) PP woven geotextile (width≥5000mm.)
(3) Bentonite powder granulation (60～220 microns), or bentonite granules from 0.5 to 3 mm
The line can produce concrete carpet with a thickness from 7 mm to 13 mm

Name of equipment and main technical parameters:
(1) Unwinding device of woven geotextile
Working width: 5300 mm
Diameter of Roller: 299 mm
Line of Speed: 1–3 m/min

(2) Tension Bracket
Working width: 5300 mm
Diameter of Roller: 219 mm

(3) Bentonite silos
Big Bags with bentonite powder or bentonite granules are lifted with the crane to the silos, then big bags are opened, and bentonite is poured into the silos.

(4) Dosing unit
From the silos bentonite is going through the dosing unite to the vibrating screen.

(5) Vibrating screen
Bentonite powder goes through vibrating screen so that the bigger particles would be removed.

(6) Elevator (screw conveyor)
Bentonite powder is feed to the Screw conveyer.

(7) Bentonite dosing machine
This machine is distribute bentonite powder on the woven geotextile.
Then it is flaten by scraper.
Working width: 5300 mm
