Grit Blasting

Grit Blasting Machine

Grit Blasting is a process that smooths a surface with the help of high-velocity abrasive material. Blasting is the acceleration of particles by air or mechanical means to a surface or workpiece to achieve a variety of physical effects. Surface effects are determined by media type, size, speed, and direction of impact. The grit blasting technique helps in obtaining the cleaning and preparation of the surfaces for the secondary finishing works. The selection of the type of grit blasting machine and equipment depends on the size and shape of the job piece. Different types of grit blasting machines are used for equipment of different sizes. A grit blasting machine also works like a sand blasting machine and shot blasting machine, the difference is that it uses grit/abrasive media.

Grit Blaster Pattern

• Inspect wheel parts daily for wear.
• Impeller-change when segments are worn 1/8".
• Control Cage-change when the beveled edge is worn 1/4".
• Blades/Vanes-change when worn 1/2 their thickness. 2.
• Check blast pattern (hot spot) regularly.
• Blast the test plate at normal work height for 20 to 30 seconds.
• Adjust hot spot approximately 8" in advance of wheel centerline. 3.2% sand and fines in the abrasive operating mix will increase wear on wheel parts by 50%.
• Maintain records of parts replacement by wheel hours so that a preventative maintenance program can be established.

Grit blasting machine process :

In machine – Throwing the grit blast media at a high speed of 65 to 110 m/second in a highly controlled way. It removed the contaminants on the surface with the help of the abrasive media impact. The process of grit blasting is at its peak. It uses compressed air for propelling the grit blast media. This method remains to clean metal frames.

The grit blast production lines (both manual and automated systems), only became possible after the introduction of the centrifugal wheel blast machines. The system of grit blasting machine with the centrifugal wheel has proven to be more productive than compressed air and achieves a better and more uniform finishing of the surface.
