Bauma 2016

CCL group company Spiroll used the recent Bauma exhibition in Munich to launch the new Spiroll Vortex Extruder, the first of a new generation of hollowcore extrusion machinery.

Spiroll – inextricably associated with hollowcore production machinery – recently acquired Dynacore, the world’s first hollowcore slab extrusion system manufacturer, enabling their knowledge and expertise to be combined to produce further advances in hollowcore production. This has resulted in the development of an extruder which still offers the benefits associated with Spiroll machines, including lower cement content, flexibility to change product depths via a 10-minute operation and excellent bond characteristics, but now includes three key features of Dynacore technology:

  • Replaceable auger ends allow the 25% of the auger most prone to wear, to be replaced without the need to remove the auger body, mandrel and follower tubes. This patented innovation minimises downtime and significantly reduces the cost of spare parts.
  • The location of vibrator motors within the forming mandrels means fewer moving parts and more direct transmission of vibration to the concrete, for improved compaction.
  • Because it has a static follower tube, the Vortex produces highly-efficient slab profiles resulting in reduced material usage, improved shear capacity and a lighter self-weight.

The new extruder proved to be a major attraction and generated a huge amount of interest from visitors from around the world.
