Vacuum Extruder

In brick and ceramic industry, this is the last machine which gives the final shape to the product. It basically consists of two main units. The first unit located on the top is a double shaft de-airing mixer. It mixes and kneads the clay material. Mud is then passed through a vacuum chamber in which de-airing of the material is achieved. The vacuumed mud is then directed towards the so called lower unit. Here the squeezing and driving augers carry the mud into the machine barrel. Finally the exrusion operation is completed by forcing the mud block through the desired die shape. This machine can handle materials with moisture ratios of 20 to 25 per cent.The double shaft de-airing mixer is a sturdy steel construction. The main body and other parts of the lower exruding machine are of heavy duty cast materials. At the outled port of the upper unit a cutter is installed. In this system the mud is brought to the most desirable condition for de-airing. Problems of over compaction and over l
