External Shot Blasting Machine

Internal External Shot Blasting Machine are two types. these are the following: 

  • Sand Blasting Machine or Pneumatic Sand Blasting Machine
  • Shot Blasting Machine for sale in India

Sand Blasting Machine or Pneumatic Sand Blasting Machine

sand blasting machine is used as a mechanical method for cleaning and removing dust particles, rust, paint, anti-corrosion coatings, and other contaminants from the metallic surface. It helps in increasing machine life by re-engineering its parts and eliminating the damages caused by wear and tear. Sandblasting machines are used in many industries for a number of applications. Different models of sandblasting machines are available for different purposes. They are manufactured in such a way that high blasting rates can be provided to the metallic surface without causing any further damage. 

The sandblasting method is mainly used for iron and steel machine equipment. Sandblasting machines help in protecting the metallic surface from the damages which may occur in the future. One can apply other coatings or painting and welding can also be done to get a smooth surface after the sandblasting process easily. After sandblasting metallic surface can be rejuvenated which can make it look new again. The sandblasting machine also helps in saving time which cannot be saved in the case of sandpaper. It is also a much more efficient method of surface finishing.

In the sandblasting machine, the metallic surface is re-engineered by using sand particles which are also known as abrasives. Different abrasives are used for different applications. Both criteria including metal surface and environment are considered while selecting abrasive media for the sandblasting process. When abrasives are propelled with the adequate pressure released by compressed air from the compressor, a better surface finish can be obtained by using a sand blasting machine.

Applications of Sand blasting Machine

  • Cleaning
  • Deburring
  • Etching & Engraving
  • Remove flashing (Excess material)
  •  Corrosion control
  •  Surface preparation
  • Shipyards
  •  Railyards

Main parts of Sand blasting Machine

  • Inlet/ Outlet valve
  • Mushroom/ Pop up the valve
  • Girt mesh
  • Pressure pot
  • Pinch valve
  • Mixing tube
  • Air-filter
  • Blasting hose
  • Remote control with Dead manhandle
  • NRV
  • Ball Valve
  • Nozzle

Working of Sand blasting Machine

The working of sandblasting is very simple. In theInternal External Shot Blasting Machine process, abrasive media is propelled out at a high velocity and pressure with the help of compressed air on the metal substrate so that the foreign particles can be thrown out of the machine surface and it can get a better texture.

In the sand blasting machine, abrasive particles are put into the girt mesh from where it goes down slightly into the pressure pot. Compressed air from the compressor comes into the pressure pot with abrasive media and is pressurized continuously.  After a certain level, when the media is pressurized, the pinch valve is opened by the operator; air and abrasive media are supplied to the mixing tube for proper mixing. Here, dual pressure develop from the media vessel and air supply tube. When both pressures are met, they pass from the blasting hose to the metallic substrate on which blasting has to be done.

Types of Sand blasting Machine

Sandblasting machines are classified mainly into two categories:

  • Cabinet type sandblasting machine
  • Portable sandblasting machine

The main difference between these two sandblasting machines is that; the cabinet-type sandblasting machine has a cabinet where blasting is done whereas portable sandblasting machines can be moved from one place to another place and can be carried to any job site with the help of wheels easily.

Cabiinet-type Internal External Shot Blasting Machine

The cabinet-type Internal External Shot Blasting Machine has a cabinet-like structure that is in close form of the machine. They are used in large industries for cleaning small-sized jobs like; mild steel, stainless steel, glass, handicrafts, wood, casting, and molds. Cabinet-type Internal External Shot Blasting Machine are also used for the applications of etching and engraving glass and granites. Also, scratches, marks, or roughness from the metallic surface can be removed with the cabinet-type sandblasting machine.

This type of sandblasting machine has an additional feature of recycling and re-using the abrasive material once the blasting is done. In cabinet type Internal External Shot Blasting Machine dust collectors are also provided so that dust particles released during the blasting process can also be collected and a cleaner working environment can be given to the operators and workers.

Portable Sand blasting Machine

Portable sand blasting machine have wheels that can carry them from one place to another easily. In this type of sandblasting machine, a large variety of abrasives can be used as per the application. They are used to remove both dust and corrosion from the metallic surface. A portable sand blasting machine can be used in many industries like; paint transformer, casting, glassmaking, powder coating, automobile, and pipe manufacturing industries.

Sometimes, carrying too much load of the machine may also cause problems to the operator; for that portable sandblasting machines are manufactured in different size models. So, one can carry the required load of the machine depending on the application.  Operators should be very careful while using a portable Sand Blasting machine. The metallic sheet should not be sandblasted in a portable sand blast machine. If the blast media is harder than the metal which is blasted; the material may leave a texture that may cause stretches to the metal. That’s why soft abrasives like walnut shells or plastic abrasives should be used.

Shot Blasting Machine for pipe or Airless Shot Blasting Machine

Shot Blasting Machine is used for the surface preparation methods in which steel shots are used as abrasive media. Shot Blasting Machine is also called Airless Shot Blasting Machine.

In Shot Blasting Machine steel shots are forcefully thrown with the help of a jet nozzle using compressed air pressure through a wheel-type machine.

Shot Blasting Machine has an effective way and with the help of these machines, we can clean hardwood, metal. Brickwork, stone.
