Things you need to Remember While buying shot blasting Machine

Are you looking to buy a shot blasting machine for your Plant or factory?  Wait a Minute! Let me tell guide you about the best machine & shot blasting machines manufacturer to collaborate in both, power and budget.  Since shot blasting is an excellent method of decreasing, cleaning and polishing metal and uses different types of media to cleanse the surface, it becomes imperative to look for a durable and compact machine that can use most types of blasting media for maximum workability.

However, force does matter in this equipment since the trajectory of media must exert friction against all sorts of dirt and grease to annihilate it from the surface and so enough pressure is required from the nozzle to get a good fine surface. Now have a look on the some of the important points and types of machines come in different categories and sizes.

Important points to note down before buying shot blasting Machine:

There are two known types of shot blasters are air currently available in the market that can be purchased and installed per user requirement.  The one is a wheel blasting machine and the second one is air blasting machine.

1. Wheel blasting machine:

Basically, wheel blasting machine is installed to treat huge machinery parts and industrial applications. Its important feature points are as follows:

● It makes use of turbine wheels rotating at great speeds and high capacity from throwing 60 kg of media per minute and going up to 1200kg/min.

● This system can cover a wide area of equipment that needs huge power consumption to clean and finish the area.

● It propels the abrasive by centrifugal force through the controlled blast pattern in an appropriate   direction.

● Wheel blasting machine has a high flow rate of abrasive therefore it is good in high production. 

● Since the turbines do most work, compressed air requirement is also low and less labor cost.

Hence, it cannot use aluminum oxide or glass beads as shot media but can typically utilize recyclable abrasive, different media like steel or stainless steel shot, cut wire, grit, or similarly sized pellets.

However, this machine is not intended to treat small or delicate parts as its forceful propulsion can dent or puncture thin metals or the area.  In general sense, the compressor power and huge motor rotation don’t fit to cure small objects because of greater abrasive consumption and force.

2.  Air blasting machine:

The second one is an air blasting machine, which uses an air nozzle that ejects pressurized blasting shots from a blasting compartment pushed by compressed air onto the area.  A factory where small parts are treated can utilize this machine because of its handy control and small space consumption. Its important feature points are as follows:

● The air blasting machine has one nozzle from which blast media is suctioned from a blast tank for the operation.

● It is intended for cleaning of small machinery parts, removing chipped surface or rat holes, hidden area cleaning and material processing before painting.

● This is usually a dry application process but some process could employ wet blasting as well.  Dry abrasive blast technique costs less and has low maintenance.

● With it, the rusty materials can be cleaned by vacuum systems to achieve desirable surface remedy at relatively low cost, however, resilient rust content could not be successfully cured by dry abrasive technique.  So, a water-based media might work better as it renders less dust formation.

● It is great for localized peening and handles critical or delicate parts using the right media.  Both aluminum oxide and glass beads can be used to shot blast the intended area.

● In this machine, air compressed blasting is effective in descaling lead paints and water-soluble impurities.

● Water-based abrasive technique drops down dry dust formation in the atmosphere as the water injected immediately behind the nozzle controls the unwanted spread of media in the environment.

● It is useful to remove a high amount of soluble salts.

Apart from it, air blasting units require a lot of compressed air and have a higher labor cost due to less area covered with each blast thrown and so more workforce is required.  Unlike wheel blasting, an air blasting nozzle has a small coverage and blast pattern.  This typically means low production and abrasive flow rates.

Hence, the basic principle is of choice and requirement.  One should know beforehand what type of material he needs to cure at the plant.  Whether it requires high abrasive flow rate or needs less force is another question. Because every machine has the different approach to surface preparation, the type, intended machine life, usage criteria, electricity consumption, industrial requirements and surface preparation are a few questions that one needs to answer by himself.
