Shot blasting is becoming an essential component which is playing a crucial role in many industries of mining, construction, petrochemical, and automotive. Due to the immense utilization of shot blasting machines throughout the world arising a high demand of shot blasting machines.
Shot blasting or abrasive blasting is generally used against the surface of the metal with a high pressure to create a rough and smooth texture by removing the unwanted substances from the metal.
What is shot blasting?
Shot blasting is the process of re-emerging the surface of metal objects by abrasive media like steel shots with the high velocity. This pounds the surface and detaches the rust and other materials.
The abrasives used in shot blasting is made by cutting the wire into the nut shells, and then loaded in the vessel provided for blast rotation.
These are very effective and efficient in nature.
How does a shot blast machine work?
Here are some points of how a shot blasting machine works:
- The cleaned work piece is to be prepared for loading on the conveyor belt, which feeds it into the shot blasting machine.
- The blasting chamber is the heart of the shot blasting machine, where the abrasive particles are propelled onto the surface of the work piece.
- The shot blasting machine has a rotating impeller wheel that propels the abrasive particles at high speed through the blasting chamber.
- The abrasive particles and dust generated during the blasting process are collected in a dust collector
- The reclamation system separates the usable abrasive particles from the waste and recycles them back into the system for reuse.
After the blasting, the work piece is removed from the conveyor belt and unloaded from the machine.
Shot blasting advantages and disadvantages
Shot blasting is a popular surface preparation method that has its advantages and disadvantages. Some of the key advantages and disadvantages of shot blasting are:
The advantages or benefits of shot blasting are:
- Shot blasting can effectively remove surface impurities, rust, and other contaminants, leaving a clean and smooth surface.
- It can increase the durability of a surface by removing existing corrosion and exposing any weakness that may require repair.
- Shot blasting is a cost-effective method of surface preparation as it can be done quickly and efficiently with minimal downtime.
- Shot blasting is an environmentally friendly surface preparation method as it does not produce any hazardous chemicals that may harm the environment.
- Shot blasting can be used for a wide range of applications, including surface cleaning, and paint removal.
The disadvantages of shot blasting are as follows:
- Shot blasting is a noisy and high-vibration process, which can be a concern in certain environments such as residential areas or buildings.
- Shot blasting can cause damage to the surface being blasted, if the surface is thin or brittle.
Shot blasting price in India
The shot blasting price in India can vary depending on various factors such as the size and complexity of the job, type of material being blasted, location of the project, and the type of shot blasting machine being used.
According to general estimation, the cost of shot blasting in India can range from 20 INR to 50 INR for per square foot and can go up to 80 INR to 120 INR per square foot for complex projects such as surface profiling or heavy rust removal.
