Difference between coarse and fine grinding;

One of the main differences between particle size and sanding is the type of abrasive used and the energy used in the process.While sandblasting uses metal abrasives that are sprayed at high speed to achieve deep cleaning and precise preparation of metal surfaces, it uses metal abrasives. While sanding uses sand or other inert abrasives. Sanding can be carried out in the open air without recycling abrasives, and is suitable for cleaning up less serious contaminated surfaces. Sand blasting uses greater kinetic energy generated by the turbine to enable metal abrasives to remove harder and more stubborn surface layers such as coatings, rust, and welding residues. While sanding is effective for many applications, it has less impact on the treated surface, making it more suitable for light cleaning and sanding jobs.
