- Zirconia Alumina: High-performance grain for heavy-duty grinding and metal removal. Offers excellent durability and self-sharpening properties.
- Ceramic Alumina: Engineered for the highest performance, ceramic grains provide the fastest cut and longest life, especially in metalworking and high-pressure applications.
- Garnet: A natural abrasive grain, softer than synthetic grains, used for woodworking, waterjet cutting, and fine finishing.
- Boron Carbide: One of the hardest materials available, used in blasting, lapping, and armor applications.
Abrasive grains are graded by grit size, which determines the aggressiveness of the cut:
- Coarse Grits (P12–P60): Used for rapid material removal, rough shaping, and heavy grinding.
- Medium Grits (P80–P180): Suitable for general-purpose sanding and surface preparation.
- Fine Grits (P220–P5000): Used for finishing, polishing, and achieving smooth surfaces.
Selecting the right grain type and grit size is crucial for achieving optimal results in any application.
The production of abrasive grains is a sophisticated process that involves several key steps:
1. Raw Material Selection: High-quality minerals such as bauxite, alumina, and silica are chosen based on the desired grain properties.
2. Fusion: The raw materials are melted in electric arc furnaces at temperatures exceeding 2,000°C, forming a molten mass.
3. Cooling and Crushing: The molten material is cooled and solidified, then broken into large chunks and crushed into smaller particles.
4. Screening: The crushed material is screened and sorted by size using vibrating sieves and air classifiers.
5. Purification: Magnetic separation and chemical treatments remove impurities to ensure consistent quality.
6. Surface Treatment: Grains may be coated with special materials to enhance performance, improve bonding, or reduce dust.
This highly controlled process ensures that abrasive grains meet strict standards for hardness, toughness, and size distribution, resulting in reliable and effective products.
