MAN-MACH's Concrete Hollow Brick Making Machine It integrates advanced mixing, molding and demolding technologies to precisely mix raw materials such as cement, sand and gravel and quickly mold them into high quality hollow bricks. The concrete hollow block machine can flexibly adjust the size, hole shape and wall thickness of hollow bricks according to different building requirements. The hollow bricks produced are not only light in weight, which can effectively reduce the dead weight of buildings, but also have good heat insulation and sound insulation properties, which are widely used in non-load-bearing walls of all kinds of buildings, and provide high-quality material choices for green and energy-saving buildings.
