Slimmer, More Powerful, Designed For Al: A New Compact Spinner-Hanger Blast Machine For Aluminium Parts
Wheelabrator SPH Spinner-Hanger Blast Cleaning Principle
New Wheelabrator SPH for Aluminium Applications (SPH-2-3/8)

Wheelabrator has launched a new compact blast machine, designed specifically for aluminium applications. Based on Wheelabrator’s trusted batch-type spinner-hanger wheel blast concept, the new SPH-2-3/8 excels at descaling, deburring/deflashing and cleaning of a variety of aluminium parts. Optimising the machine for this application enabled the design team to also reduce its price significantly.
Like other members of the SPH family, the new machine features two blast chambers that form two halves of a cylinder that rotates around the vertical axis. This enables simultaneous loading/unloading and blasting, which in turn results in a more efficient use both of space and of the two blast wheels.
Design engineers at Wheelabrator based the new machine on an existing model in the SPH range (SPH-2-3/9), which was designed for a broader range of applications and therefore required heavier construction.
By matching the new SPH-2-3/8 exactly to the needs of aluminium applications, a lighter and slimmer design could be achieved. A pleasant side effect: the final machine price is considerably lower compared to the heavier sister machine.
A step change in performance
At the same time, blast power and abrasive throughput have been increased considerably compared to the SPH-2-3/9 (total abrasive throughput was increased from 174kg/min to 300kg/min).
This step change in performance is due to the SPH-2-3/8’s two state-of-the-art TITAN 14.3 blast wheels (double-disk, eight blades, wear parts made of tool steel), which achieve better blast results faster, thanks to their higher input power and blast power.
Stanislav Venclik, Vice President Portfolio Development at Wheelabrator, comments on the new machine: "Aluminium applications are on the rise and the launch of this new machine reflects that. Its compact design will suit tightly structured aluminium production environments, including cell layouts.
It can accommodate a variety of workpieces while still achieving superior process efficiency and seamless integration into the flow of production. In addition to this, the team has made a number of tweaks to further improve machine reliability and uptime."
Compact and versatile
The new SPH-2-3/8 features a pitless design for fast installation (and mobility), as well as a compact footprint of less than 1.5m by 1.5m.
The hanger carrying the workpieces has a height of 800mm, with a maximum envelope circle diameter of the loaded hanger of 300mm. The maximum load is 150kg per hanger.
