The working principle of sand blasting machines involves the use of compressed air or a mechanical means to propel abrasive materials onto a surface. There are two main types of sand blasting machines based on their working principle:

1.Air-Powered Sand Blasters:

These machines use compressed air to accelerate abrasive particles through a nozzle, which is directed at the surface to be treated . The force of the abrasive particles removes surface materials or contaminants.

The pressure can be adjusted depending on the material being blasted and the desired effect.

2.Mechanical Sand Blasters (Wheel Abrators):

These machines use a spinning wheel to propel abrasive materials onto the surface . The wheel's centrifugal force accelerates the abrasive particles, which are then directed at the workpiece.

This type is more suitable for heavy-duty applications and can handle larger volumes of abrasive material.
