Henan Sicheng Abrasives Tech Co., Ltd was established in 2009 and is an integrate garnet mining, processing shipping ,global marketing and distribution organisation providing the high quality indusrtrial garnet for the surface preparation, waterjet cutting , water filtration and polishing industries. 
Garnet Sand: A natural, hard, sharp, and inert mineral (an aluminum silicate). It is non-toxic, dust-free, and contains no hazardous silica, making it a popular, environmentally safer alternative to silica sand.
- 20-40 mesh / 30-60 mesh: This indicates the particle size range, determined by which standard sieves the grains can pass through.
- 20-40 Mesh: Particles will pass through a 20-mesh screen (aperture ~0.84 mm) but are retained by a 40-mesh screen (aperture ~0.42 mm). This is a coarser grade.
- 30-60 Mesh: Particles will pass through a 30-mesh screen (aperture ~0.59 mm) but are retained by a 60-mesh screen (aperture ~0.25 mm).

Key Characteristics and Advantages
This size range of garnet is chosen for its excellent balance of performance characteristics:
Fast Cutting Speed: The hard, sharp grains quickly remove rust, old paint, and mill scale.
Optimal Surface Profile: It creates a strong, clean anchor pattern (typically between 50-100 microns or 2-4 mils), which is ideal for the adhesion of protective coatings.
Low Dust & No Free Silica: Generates very little dust during operation and is free of crystalline silica, protecting operator health and reducing environmental contamination.
Reusable & Economical: Due to its high durability and resistance to fracturing, it can be recycled multiple times in blast recycling systems, lowering the overall cost.
High Density: The dense grains carry more kinetic energy, leading to higher impact force and productivity, with less rebound and overspray.
Chemically Inert: It will not contaminate the surface being treated.
Applications
Heavy-Duty Steel Surface Preparation:
Removing thick rust and coatings from ship hulls, bridges, storage tanks, and offshore platforms.
Achieving a clean surface (e.g., Sa 2.5) with a sharp anchor profile for high-performance coatings like epoxy zinc primers.
Metal Parts Cleaning:
Descaling castings and forgings.
Removing welding spatter and smoothing welds.
Pipeline and Tank Interiors:
Cleaning and profiling the interior surfaces of pipes and vessels in the oil and gas industry.
Waterjet Cutting:
This size range (especially 20-40 mesh) is a standard grade for abrasive waterjet cutting, where it is mixed with a high-pressure water stream to cut through metal, stone, and glass.
20-40 mesh / 30-60 mesh blasting garnet sand is a versatile, efficient, and economical industrial abrasive. It is the go-to choice for heavy-duty rust and coating removal where creating a high-quality surface profile for new coatings is critical. Its reusability and lack of hazardous silica make it a superior and safer choice for many blasting operations.
