A method of manufacturing ceramics, mostly brick, using dry pressing and production line for its production

 

(57) Abstract:

1. A method of manufacturing ceramics, mostly brick, using dry pressing, comprising granulating raw clay, coating the surface of the granules powder components, drying the granules, extrusion billets, drying and firing, characterized in that the surface coating of granules powder components granulation and drying of the granules is carried out in a countercurrent fluid saturated pulverized waste, formed during drying, roasting and grinding, after which the granules are crushed to the size of the target fraction for pressing.

2. The method according to p. 1, characterized in that the granulation is carried out by forcing the clay material with a moisture content of 20-25% (by weight), through the perforated lattice with cylindrical holes with a diameter of 10-20 mm, subsequent crushing of granules in a countercurrent fluid saturated with powdered clay.

3. The method according to p. 1, characterized in that the granulation and drying of the granules is carried out in a countercurrent coolant, which initially served through the zone drying granules, where the latter is moved towards the carrier is stirred and partially estlat to a moisture content of 6-12 wt.%.

5. The method according to PP.1 to 3, characterized in that as the coolant using flue gases from the furnace of burning products, which serves for drying the granules.

6. The method according to p. 1, characterized in that the target fraction for pressing is prepared by grinding to particles with sizes up to 3 mm

7. The method according to p. 1, characterized in that the drying and firing blanks produced in bunk slot of the furnace, and the drying of the products is done in the lower tier of the furnace feed flue gases to heat the product at the end of drying to a temperature of 700-800oC.

8. The method according to PP. 1-7, characterized in that as the coolant using flue gases from the cooling zone of the billet upper tier bunk slit furnace with a temperature of 250-280oWith that serves for drying the granules.

9. The method according to p. 1, characterized in that the pressing of the target fraction is carried out with a vibration with a frequency of 40-50 Hz.

10. The method according to p. 1, characterized in that the pressing of the target fraction is carried out at a pressure of 30-40 MPa.

11. Technological line for the production of ceramics, mostly brick, using dry pressing, contains a section for pre-processing raw clay, firing, exhaust system, characterized in that it is provided with pellet placed in the chamber, communicated with the volume of the drying drum, and means for grinding the granules, and the plot for drying and firing made in the form of bunk furnace cooling zone which are connected by Tribolodon exhaust gases through the outlet pipe of the dryer drum and the camera granulator with an exhaust system.

12. Technological line for p. 11, characterized in that the pipe discharge gas on the piece that connects the discharge port of the drying drum and a cooling zone bunk furnace equipped with a heater.

13. Technological line for p. 11, characterized in that it is provided palisadium devices between the camera granulator and retractable system.

14. Technological line for p. 11, wherein the pressing section is equipped with at least one pressure for dry pressing.

15. Technological line for p. 11, characterized in that the pressing section has a number of presses for dry pressing, which is included in the line up.

16. Technological line for p. 11, characterized in that each channel bunk selavo trichomania fact, what clothes dryer equipped with auger attached to the inner surface of the drum, and its axis is a through axial channel.

18. Technological line for p. 17, characterized in that on the inner surface of the drying drum between the blades of the auger fixed cantilever racks are placed evenly along the drum and its circumference.

19. Technological line for p. 11, characterized in that the means for pulverizing the granules made in the form of two abrasive surfaces, one of which is movable with the actuator and has a crackler, and the second stationary made in the form of mesh or plate with holes, which is placed under the crackler.

20. Technological line for p. 19, characterized in that the fixed grid or plate is combined with means for separation of the products of abrasion of the granules.
