Shot blasting is one of the most effective surface treatment processes for finishing and cleaning operations. It is a technical method used to remove any impurities from different surfaces using abrasives. Different industries use a piece of modern equipment known as the Shot Blasting Machine to carry out this complex procedure for surface treatments. 

In this blog post, we look at the shot blasting techniques, applications, and benefits with some important FAQs related to blasting machines. 

Shot Blasting – What is this Process?

Shot blasting, an important aspect of preparing materials for use or manufacturing operations, includes the application of metal shot to the material of choice – most typically metals. Several industries utilize the shot blasting process to treat the surface of the metal using high-velocity steel abrasives in a controlled manner. 

These high-speed controlled blasts produce an abrasive impact that eliminates surface impurities, making it an efficient way for cleaning and finishing iron, steel, forgings, machine components, etc. A shot blasting machine is an excellent way for cleaning and prepares surfaces for painting or other finishes, but not all procedures are the same.

Shot blasting employs a variety of metal abrasives, ranging from steel grit and copper shots to aluminium pellets. Other materials used in shot blasting include silica sand, glass beads, synthetic materials, and agricultural commodities such as crushed kernels.

Why Do You Need a Shot Blasting Machine?

While the procedure is very simple, it must be carried out with extreme caution. Any abrasive shot used in the blasting process will be pushed at high speeds and might cause serious injury to workers if they don’t follow proper precautions. Shot blasting is a highly adaptable method that can contribute to mission-critical goals due to its capacity to swiftly treat the materials.

When done properly, this process can help improve the appearance and lifespan of any materials that undergo treatment. Using advanced and cutting-edge shot blasting machines and training can enable teams or contractors to perform to the highest standards without sacrificing quality.

A shot blasting machine allows workers to apply abrasive material to the work items safely and more efficiently. This can range from small machines for stripping concrete floors to room-sized systems for cleaning and stripping industrial machine parts or other work items. Whatever shot or grit blasting equipment you use, the kind and specification of shot or grit are critical to achieving the desired results.

This might include using steel or stainless steel spherical particles (shot) or extremely abrasive steel and stainless steel grit to obtain the most productivity and cost-effectiveness out of your blasting equipment.

The Working Process of a Shot Blasting Machine!

A shot blast machine works by propelling abrasive shot material against the surface of a metal or steel using a centrifugal wheel to remove impurities or clean the surface. The abrasive material is directed to the surface at high speed while the wheel revolves, preparing the product for finishing. During the process, contaminants from the surface are collected in the dust collection system of the blasting machine.

Industries use shot blasting machines to apply abrasive shots directly to a material or surface of your choice. This can include the use of steel shot for peening activities, which allows metals to be reinforced for their intended purpose, as well as desanding and descaling components.

Shot blasting, on the other hand, is most typically used as a pre-treatment process to prepare surfaces for new coats of paint or to remove defects. This enables the application of a firm, uniform base coat that provides coverage and a high-quality finish.

Different Abrasive Delivery Options Used in Shot Blasting Machine

Two different techniques can be used to propel a shot material against the surface of a metal. The criteria for selecting the appropriate technique will be determined by the area of application, such as surface condition, end finish standards, and so on. Here are the two abrasive delivery alternatives available to you.

Compressed Air (Pneumatic)

The option is ideal for tasks with a modest output rate. This air-blasting machine employs compressed air to speed up steel shots that may be guided horizontally, making it an excellent choice for completing steel welds and frames. As a consequence, it almost eliminates the need for hand tools!

Centrifugal Turbine

For finishing and cleaning, the centrifugal wheel approach is a more popular and cost-effective solution. This process is also known as wheel blasting. It uses a centrifugal turbine to push abrasive shots in a precise direction at a regulated speed. The amount of cleaning required will determine the power of the centrifugal turbine utilized in this sort of blasting equipment. 

Most of the top Shot Blasting Machine Suppliers In India offer air blasting and wheel blasting equipment for different applications to improve job efficiency.
