Fine Sand Slinger

The Fine Sand Slinger prevents faults in the castings surface caused by lumps in the mould sand that would necessitate extra fettling.

The coarse moulding sand is fed to a brush roller arranged on the outfeed side of the sand hopper. The brush roller is equipped with steel bristles and rotates alongside a fixed panel so as to provide a restricted space through which the sand must pass. Sand lumps are broken up and passed through as fine sand grains. The rotary movement of the brush causes the sand to be thrown against the pattern tangentially.

- Faultless filling of tight pattern pockets
- Accurate contour reproduction of complex pattern zones
- Significant improvement in surface structure
- Improvement of compacting effect
