Walnut shell granulates

Walnut shell H 1 granulate impregnated with polishing paste

This granulate is impregnated with a polishing paste so that no further polishing paste need be added for the first 3 - 4 batches. Typical applications: mirror-finish polishing of precious metals, jewelry, titanium and steel alloys  

Type Grain size Properties / surface
H 1/30 4.0 - 6.0 mm very smooth surface
H 1/50 2.4 - 4.0 mm very smooth surface
H 1/100 1.7 - 2.4 mm very smooth surface
H 1/200 1.3 - 1.7 mm very smooth surface
H 1/300 0.8 - 1.3 mm very smooth surface
H 1/400 0.4 - 0.8 mm very smooth surface
H 1/500 0.2 - 0.4 mm very smooth surface

Walnut shell granulate H 2 impregnated with grinding paste

This granulate is impregnated with a grinding paste so that no further grindig paste needs to added for the first three or four batches.

Type grain size Properties / surface
H 2/30 4.0 - 6.0 mm smooth surface
H 2/50 2.4 - 4.0 mm smooth surface
H 2/100 1.7 - 2.4 mm smooth surface
H 2/200 1.3 - 1.7 mm smooth surface
H 2/300 0.8 - 1.3 mm smooth surface

Walnut shell granulate H 3 impregnated with PP 01 polishing paste

This granulate is impregnated with a polishing paste so that no further polishing paste need be added for the first 3 - 4 batches. Typical applications: tungsten carbide, ceramics 

Type Grain size Properties / surface
H 3/400 0.4 - 0.8 mm Smoothing edge rounding to 10 μm Polishing tools

Walnut shell granulate H 4 impregnated with PP 02 polishing paste

This granulate is impregnated with a polishing pastr so that no further polishing paste need be added for the first 3 - 4 batches. Typical applicatioins: tungsten carbide, ceramics  

Type Grain size Properties / surface
H 4/400 0.4 - 0.8 mm As H 3/400 but better shine ideal polishing results for tungsten carbide suitable for removing droplets
H 4/500 0.2 - 0.4 mm As H 3/400 but better shine ideal polishing results for tungsten carbide suitable for removing droplets

Walnut shell granulate H 0 unimpregnated

Granulates can also be supplied unimpregnated (walnut shell granulate H 0). This granulate must be impregnated with a grinding or polishing powder before it is first used. Dosage: 5 -10 teaspoons / 5kg walnut shell granulate.
