Shot Blasting Machine Manufacturer in India: Types, Parts, Uses & Price Guide
A good coating starts with a clean surface. Rust, mill scale, weld slag, sand and old paint have to come off before steel is painted, powder coated, plated or galvanized, and doing this by hand is slow and uneven. A shot blasting machine cleans the surface mechanically by throwing steel shot at it at high speed, so you get a uniform, slightly rough metal finish that coatings bond to well. Airo Shot Blast is a shot blasting machine manufacturer in India, based in Jodhpur, making shot, sand and grit blasting machines and equipment for foundries, forging units, steel processors, fabrication shops and auto-component makers. This guide explains what a shot blaster is, its six main parts, how it works, the types available, where each is used, which abrasive to choose, what decides the shot blasting machine price and which safety points matter, so you can choose the right machine and compare quotes with confidence.
What Is a Shot Blasting Machine?
A shot blasting machine is equipment that cleans, descales or peens metal parts by throwing abrasive at them with force. Each machine is designed for a particular customer requirement. The impact separates rust, weld slag, scale and corrosion from steel parts and leaves a uniform metal colour, which improves the quality of the coating that follows and helps prevent corrosion.
A typical machine includes a blast chamber, a work handling or conveying mechanism, an abrasive recycling system, a dust removal system, maintenance platforms and an electrical control system. It is also used for shot peening, where controlled shot compresses the surface of springs, gears and other load-bearing parts so they resist fatigue.
What Is a Shot Blaster? (Steel Shot Blaster Explained)
A shot blaster, or steel shot blaster, is simply the common name for the machine. In most industrial shot blasters, a blast wheel with paddle type blades throws steel shot at the surface at high velocity. The shot size is chosen for the job. A smaller shot produces a smooth, polished surface, while a larger shot removes heavy flash and scale.
There are two ways to throw the shot:
- Airless (wheel) blasting: an electric motor spins the blast wheel. There is no compressed air, so the running cost per part is low. This is the standard choice for production work.
- Air-operated (pneumatic) blasting: compressed air carries the abrasive through a nozzle. It is more flexible for small batches, site work and awkward shapes. See our sand blasting machine and portable sand blasting machine.
Main Parts of a Shot Blasting Machine
A shot blasting machine has six basic parts:
- Blast wheel: the heart of every centrifugal shot blasting machine. The number of wheels depends on the job and the work rate, and the efficiency and cleaning effect depend largely on the quality of the wheel and its components.
- Cabinet: the blasting happens at very high abrasive speed, so the chamber must be closed and vibration free. It is made of strong steel and lined with wear-resistant alloy plates for safe performance.
- Work handling mechanism: the system that carries the parts (a tumbling belt, hanger, table, roller conveyor and so on). The choice depends on the type, size and quality of the parts.
- Elevator: used abrasive collects at the bottom of the cabinet, and a screw conveyor takes it to the base of the elevator, which lifts it to the separator.
- Separator: cleans the abrasive of dust and contaminants before it returns to the wheel. An air separator keeps the abrasive entering the wheel clean.
- Dust collector: takes dust-laden air from the separator and the cabinet, cleans it, and discharges clean air outside. It keeps the working area free of dust and protects the health of the workers. See our dust collector.
How Does a Shot Blasting Machine Work?
- The parts are loaded and carried into the closed blast chamber by the work handling system.
- The blast wheels throw steel shot at the parts while they tumble, rotate or move on rollers.
- The shot and debris fall to the bottom and are carried by the screw conveyor and elevator to the separator.
- The separator removes dust and fines, and clean shot returns to the wheel.
- The dust collector keeps the chamber under suction so dust does not escape.
- The cleaned parts leave the machine ready for painting, coating or the next process.
The whole process is controlled by factors such as shot impact force, shot size, machine speed and abrasive flow.

Key Features of Our Blast Wheel
The blast wheel decides how well the machine cleans and how long it runs between repairs. Our wheels have:
- High efficiency: a special impeller design, with blasting efficiency of 16 to 19 kg per minute per kW.
- Protective liner and sealing: the top cover is cast iron with two layers of wear-resistant rubber that protect and seal it.
- Lower noise: a cushioning rubber at the bottom of the wheel reduces vibration.
- Strong runner wheel: made of 40Cr material, carburized and hardened, and checked on a balance detection process.
- Precision machining: all key parts are machined on a CNC centre, so the wheel stays accurate and balanced at high speed.
- Easy blade change: the eight blades come off in just 5 to 10 minutes, and the condition of the impeller, blades and control cage can be checked easily.
- Long-life material: the impeller and blades are made of high chrome alloy.
- Balanced blades: the weight difference between blades is less than 8 grams.
- High throw: a two-disc impeller wheel with short blades that gives high throwing ability.
Advantages of Using a Shot Blasting Machine
- Cleans and descales the surface.
- Adds texture that improves paint adhesion.

- Gives the same finish on every batch.
- Lower cost per part than manual cleaning.
- Designed with three-dimensional modelling, which helps avoid design defects and omissions.
- One-stop service from design and production to delivery, installation and after-sales support.
Where Are Shot Blasting Machines Used in India?

Shot Blasting Machine Price in India
The shot blasting machine price depends on your requirement, not just the machine name. The main factors are:
- Machine type: a cabinet, a tumblast machine and a multi wheel hanger or conveyor machine are in very different price brackets.
- Number, size and power of blast wheels: more wheels and higher HP clean faster and cost more.
- Chamber and part size: larger loads need larger chambers and stronger construction.
- Throughput target: tonnes per day or parts per hour decide the wheel count and the dust collector size.
- Automation: manual, semi automatic and PLC controlled lines are priced differently.
- Dust collector, abrasive recycling system and accessories.
- Delivery location and installation.
We manufacture the machines ourselves, so you get factory direct pricing, customization and after sales support. Share your part type, size, material, weight per batch and daily output, and our engineers will send a configuration and quote, usually within the same working day.
Important Safety Considerations
- Door interlocks: the wheels must not run while a door is open.
- Dust collection: keep the dust collector in good condition. Fine dust from blasting is a breathing hazard.
- PPE: use eye and ear protection, gloves, and respiratory protection during maintenance and cleaning.
- Wear parts: inspect liners, blades and seals regularly, because worn parts let shot damage the chamber.
- Pneumatic and portable work: use a dead man handle, secure hoses and trained operators.
- Maintenance: only trained staff should open the chamber or wheel housing, with the power isolated.
