Introduction

• A surface finishing process that involves impel
  machines is known as the sandblasting process.
  Also known as abrasive blasting.  Normally
  sandblasting and air compressors are used to
  spray abrasive particles on the surface with high
  pressure.  
• It is called sandblasting because it blows up the
  surface with sand particles. When the sand
  particles hit the body, the soft texture takes
  place. 
• Sandblasting makes the most of sands abrasive
  properties have a soft and glossy surface
  however, some flaws also exist as physical
  faults. Its a fact that sand is rough and
  chopped due to these properties, its easy to
  wash away excess of it from the surface.  
• Sandblasting works in the same way as sandpaper.
  When it is rubbed on the surface it eliminates
  the excess material and creates a softer
  texture.

How Sandblasting Process Takes Place

• The sandblasting process starts with pouring the
  sand in the machine. It has a chamber through
  sand that is easily poured and filtered. The
  sandblasting device is also attached to an air
  compressor that further impels the sand particles
  through the nozzle. 
• You have to set the pressure it depends on the
  settings. The standard pressure for the sand may
  vary with 50 to 130 PSI ( pound per square
  inch). 
• The sand is later burst on the soft surface. Its
  abrasive properties help in creating a
  frictionless surface. For example, cement is the
  outcome of sandblasting. When it is spilled and
  leaves it to dry, then sandblasting is
  applicable. 
• On the other hand, mobile media blast is in
  demand for many different purposes. Rust and
  paint removal is the most common use of it.
  Indeed it is very efficient for removing rust or
  paint from any type of surface instantly. 
• It is simply done by impelling sand by applying
  high compressed air. When the gritty material
  hits the surface, the rust is eradicated easily.

Step 1 Decide Space For Operations 

• Clear out your workspace make sure that there
  will be no harmful material around you. Usually,
  flying abrasive material hit toxic materials and
  cause incidents. So keep your precious belongings
  safe by covering themsafe them from being
  sandblasted. The space you chose for the
  sandblasting process should be open and airy.

Step 2 Make Yourself Safe

• Sandblasting is a very tricky and sensitive
  process. For that, you have to take safety
  precautions before starting it. It includes a
  helmet, face masks, and Gloves. If you dont have
  it, find an alternate the only thing you have to
  safely is your skin. You must cover it
  completely.

Step 3 Set the Sandblaster 

• To start any machine, it is the primary step to
  go through its manual thoroughly. As the
  sandblaster has the valves on its blasting unit
  and that needs to get close tight. Abrasives
  materials need to be fill in the tank,  with the
  help of a plastic funnel. Keep in mind that there
  are many types of abrasives easily available such
  as glass, silica sand, nutshell, etc.

Step 4 Set the Pressure Attentively

• First, to set the pressure, open the primary air
  valve and allow the tank to reach a minimum
  pressure of 40 PSI. It also depends on the
  different types of equipment. After a good
  pressure, the tank unlocks the sand air valve.

Step 5 The Blasting 

• In this step of the sandblasting process, shut
  down all the valves and move the nozzle against
  the target. Set it on a slight angle then apply
  composed motion. Stretch the target part with
  abrasives.

Step 6  Absolute Settings 

• Now you will gently increase the pressure to
  attain the likable results. You can take the
  pressure to a maximum of 100 PSI and keep examine
  the outcomes. After fixing the result, keep
  checking on the obtained results if optimal or
  not. Close all the valve and nozzle once you
  reach to the point.

Conclusion 

• Sandblasting is one of the most acceptable types
  of surface finishing. It is best for rough and
  challenging spaces. Simply it is the process of
  polishing and grading uneven surfaces by striking
  solid particles. With compressed air at high
  speed the process takes place placidly.
