Shot Blasting Machine | Shot Blasting Machine Price in India

Shot Blasting Machine is used as a mechanical method for the surface treatment by using an abrasive with the help of a centrifugal wheel at high speed to obtain excellent surface and remove impurities for secondary operations.



Shot blasting is used for the following main purposes:

  • It provides a better texture to enhance paint adhesion.
  • It increases the coating life of a machine by reducing its maintenance cost.
  • For cleaning and preparing the surface before painting, coating, metalworking.
  • It also used for making non-slipping surfaces and providing surface homogenization.
  • Shot blasting is done after heat treatment and also for mechanic descaling.

The shot blasting is done in two ways:

  • Wheel blasting: It is a common and economical method. In this process, the electric motor energy is converted into kinetic energy by rotating a turbine wheel. This is mostly used for treating heavy equipment. The turbine wheel works here as a centrifugal pump and it delivers the abrasive by centrifugal force on the surface.
  • Air blasting: In this method compressed is used and sprayed out through nozzles on the surface.  This is mostly used for smaller equipment.  Air blasting is comparatively expensive due to the use of steel frames and weldments.

After the process of shot blasting, shots are removed by the air washing process.

The shot blasting machine works on the projectile motion of an abrasive on the metal surface to get a better surface finish. So, this mechanical method depends on the abrasive. For this, mostly metal abrasive should be used.

Metal abrasives can provide the following benefits

  • They can increase productivity by reducing maintenance costs.
  • Waste generation can be reduced to get better quality of work.
  • They cause less environmental pollution and also there is no risk to the operator’s health by using metal abrasive.

Thermal Spray Gun   is used for coating processes in which melted materials are sprayed on the surface to provide better polishing and remove foreign particles. Thermal spray guns provide thick coatings up to several mm depending on the application.   Thermal Coating   materials available for thermal spraying include metals, alloys, ceramics, plastics abrasives, and composites. The coal thermal spray guns are used for coating processes in which melted materials are sprayed on the surface to provide better polishing and remove foreign particles. Thermal spray guns  are used to improve the metal surface. The main purpose of using a thermal spray gun is the expand the rotating shaft and increasing the life of the  sand blasting machine . The thermal spraying method can come up with a thick coating over a large area at a high deceleration rate as compared to more coating processes. The thermal spray gun melts the material which results in molten droplets accelerated...

 From: sand blasting hopper Sand blasting Machine A  Sand Blasting machine  is mainly used to remove rust, corrosion, and contaminants from the metal surface with the help of abrasive media. In the sand blasting machine, silica sand is used as an abrasive for sand blasting operation. A  Sand blasting machine  is also used to mold and to clean the surface of the metal. For this blasting process, compressed air at high velocity and pressure is imparted on the blast wheel. The sand blasting machine is the strongest method among all the other blasting methods.  Types of Sand blasting machine Pressure blasting machine Suction blasting machine Wet blasting machine Working of Sand blasting machine In the sand blasting machines, compressed air with abrasive is used for surface preparation. It is one of the most efficient and fast methods of blasting.  The sand blasting machine involves the operation of forcibly propelling a stream of abrasive material against ...
