waterjet abrasive garnet sand

Garnet is a natural product with chemically inert, non-toxic metals and crystalline silica.

With its good hardness,garnet has been used as a gemstone and blasting abrasives.

The density of pure waterjet energy is often insufficient for machining many technical materials. In respect of appropriate applications the waterjet is supplemented solid particles . 

Therefore the waterjet machining can be used also for materials which can not be machined just by pure waterjet application . 

An application of additional abrasive agent causes also a significant increase of the cutting capacity in comparison to pure waterjet technology . 

For the so called abrasive , mineral materials with sharp edges are used , like garnet sand or olivine with grain sizes approx 0.1 to 0.3mm . 

For abrasive  cutting , depending on application , the required quantity of the abrasive materials varies from 100 to 800g per minute . 

For both technologies the applied pressure reached up to 6000bar . 

The jet diameter ranges between 0.3 to 1.2 mm . 

Cutting together with abrasive agent also enables cutting of materials with thickness up to 300mm .

Processing Technics:

Select the rock with 85.4% garnet. Artificially dry it to reduce the moisture to 4.7%. After smashing by machine, acid wash (remove impurity) and water wash (remove sand and dirt) and second artificial dry ( to get rid of dirt) to reduce the moisture lower than 5%. Finally sifting screen technics makes them more even. And pack.

Recommendation: 60Mesh abrasive is used to cut stainless steel, copper, marble.80Mesh abrasive is used to cut ceramic and glass wares.
