Compact Vacuum Extruder
Technological Functions
A compact vacuum extruder is used for shaping brick products, by mixing, vacuuming, compressing, and through the reamers and mold, to form the initial shape of clay strips.
The material gets well balanced during the shaping process, with increased plasticity and strength by creating a vacuum space before the final step of extrusion, the brick surface also becomes much smoother.
Structure and Principles
A compact vacuum extruder consists of the base, an upper mixing tank, a lower extrusion tank, a vacuum chamber, reducers, and an extrusion head. The compact design allows the one motor to power both the mixing shaft and the extrusion shaft.
The material is fed into the mixing tank through the belt conveyor, added with water or steam during the mixing process to acquire great flexibility over the adjustment of water content of the material while increase the extruded green body temperature. The material is mixed in the mixing tank while moving towards the vacuum chamber, pushed into gradually shrunk spaces by the compression force of the spiral mixing blades, thus sealing the material inside the vacuum space, the radial clay cutter chops the material into thin slices, then fall into the spiral reamers, while the air is extracted by the vacuum device beneath. Hence, the material has been compressed and shaped by the reamers.
Features
Compact, stable structure and durable spindle design.
The spindle and reducers adopt geared pin-coupler, with appropriate flexibility.
The reamers adopt advanced tungsten carbide plasma intelligent welding technology, making them highly wear-resistant
Suitable for small/medium sized production plants, with low operating costs and maintenance workload
