SGA80
25132000
SGA 80 is a natural alluvial pink garnet abrasive for common waterjet cutting applications. It provides stable abrasive feeding, smooth cutting edges, lower dust and consistent particle distribution for stainless steel, aluminum, stone, glass, ceramics and composite materials.
SGA 80 is produced from alluvial pink garnet through washing, separation, drying and precision screening. The 80 mesh grade is commonly used in waterjet cutting machines because it balances cutting speed, edge quality, abrasive flow and consumption cost.
80 mesh waterjet garnet is widely used for general precision cutting where stable abrasive feed, smooth edge quality and reliable productivity are required.
For stainless steel, carbon steel, aluminum, titanium and other metal cutting applications.
For stone slabs, glass, ceramics and composite materials requiring clean cutting edges.
SEPPE processes alluvial garnet through washing, desliming, gravity separation, drying, magnetic separation and precision screening to control oversized particles and fines for stable waterjet cutting performance.(You can click on "Quality Control System" on the second page to view the specific generation process.)
For waterjet cutting, particle size distribution, moisture, bulk density and chloride content directly affect abrasive flow, cutting stability and nozzle service life. SEPPE checks each batch before shipment.

| #40 | 425 µm | 0% | 0% |
| #45 | 355 µm | 0% | 0% |
| #50 | 300 µm | 10% | 10% |
| #60 | 250 µm | 30% | 40% |
| #70 | 212 µm | 28% | 68% |
| #90 | 170 µm | 26% | 94% |

Values shown are typical product data from the current SEPPE SGA 80 technical data sheet. Order-specific documentation is available on request.
Consistent SGA 80 grading depends on control throughout the production process. Raw garnet is selected, separated, washed, dried and precision-screened before finished-product samples are inspected for packing.
Selected alluvial garnet provides the starting material. Particle condition, mineral composition and unwanted material are reviewed before processing.
Magnetic separation uses differences in mineral magnetic response to help remove selected impurities before further processing.
Washing removes clay, fine dust and loose material from the particle surface before drying and grading.
Controlled drying reduces moisture before screening and supports free-flowing abrasive during packing, feeding and waterjet use.
Vibrating screens classify the dried garnet into the required SGA 80 grade while controlling oversized grains and excessive fines.
Finished-product samples are checked against the applicable particle-size and order requirements before packing.
Contact SEPPE with the required quantity, waterjet model or mixing-tube requirement and destination to request the current technical data sheet and available order documentation.
