High amount of noise is produced by these Shot, therefore protective equipment-noise mufflers must be used.
Shot blasting machines use techniques of different types which are been used for different industrial purposes:
Abrasive blasting: In this method, abrasive materials like sand, high pressure air, water or small glass particle is sprayed at high speed on metal which needs to be polished or cleaned. Other organic and environment friendly materials like basking soda can be used as blasting medium.
Grit blasting: In this type, medium used for the purpose of blasting is fine sand particles. This blasting is used for smoothing the rough metallic surface. Grit blasting is used for a frosted effect on metal or for cleaning off the paint from metallic surface.
Bead blasting: In this blasting, fine particles of glass are used instead of sand for blasting. This blasting is used for cleaning floors of swimming pool and clean paint from automobiles. Once procedure of sandblasting gets completed, you must get the machine checked properly by an expert who can make sure that all nozzles and equipment are in good and safe conditions.
