Production line for magnesium oxide board with fashionable design, reasonable structure, stable running manufactured board of even thickness in large production once through double- roller-extruding technology. this production line is equipped with shaking device which remove inside and outside air bubble, so our board is more compact. in addition, we use the no-woven cloth as the separating film to increase the toughness and strength of the board. the machine can be adjusted arbitrarily, and then produce the board with the thickness of 2-60mm, the biggest width of 1, 300mm and unlimited length. so you can adjust the thickness of board at will.
