Sandblasting machines use compressed air or liquid to drive abrasives to spray the surface of the workpiece at high speed. This can achieve cleaning, roughening, deburring, and performance optimization. It is widely used in metal processing, precision manufacturing, automotive, aviation, art decoration, and other fields. The advantages are efficient processing of complex surfaces, improved coating adhesion, and wet sandblasting is environmentally friendly. Now, sandblasting machines are in line with environmental protection concepts and are indispensable surface treatment equipment in modern industry.

Types and Differences of Sandblasting Machines Produced by YG
There are many types of sandblaster machines produced by YG; the most commonly used are dry and wet types.
1. Dry Sandblasting Machine
Dry sandblasting machines use compressed air to blow out sand and have a strong impact. It is particularly fast to clean thick rust and hard cement stains, and is suitable for outdoor large-scale operations. But it will produce some dust, so it is best to wear a mask.
2. Wet Sandblasting Machine
A wet sandblasting machine will carry water when sandblasting. Sand and water are mixed and sprayed out, and there is much less dust. It is suitable for indoor or places with high environmental requirements, such as cleaning engine parts in auto repair shops. The prices of the two machines are similar; the dry type is more suitable for rough work, and the wet type is more suitable for fine processing.

People’s Use Scenarios of the Mini Sandblaster
Usage of Dry Sandblasting Machines:
- Dry sandblasting machines have a strong impact and are suitable for outdoor rough processing. Construction sites use it to clean thick rust on scaffolding, and the metal can reveal its original color in a few minutes.
- When shipyards process the exterior of the hull, they use it to quickly remove the old paint and prepare for new painting.
- Scrap recycling stations also often use it to remove dirt on the surface of old parts for easy classification and reuse. 4. In these open places, dust is easy to spread, and the high efficiency of dry machines is fully utilized.
- Dry sandblasting machines are very practical in the renovation of large steel structures, such as bridge railings and factory steel beams, and can quickly deal with large areas of rust.
Application Scenarios of Wet Sandblasting Machines:
- A wet sandblasting machine is more suitable for scenes with high environmental requirements. Auto repair shops use it to clean oil stains in the engine compartment. Water and sand are mixed and sprayed to prevent dust from dirtying precision parts.
- When furniture factories treat solid wood furniture, they can use it to accurately control the force, so that the wood surface presents a natural texture without damaging the interior.
- When electronics factories process metal casings, wet sandblasting can prevent dust from entering the circuit and protect equipment safety.
- Wet sandblasting machine is suitable for processing small indoor objects, such as cleaning hardware accessories and mold surfaces, which can be cleaned and are environmentally friendly.
How Does a Sandblasting Machine Work?
- The working principle of the portable sandblaster machine is very simple, just like using a high-pressure water gun to flush out dirty things, but the water is replaced by sand.
- First, pour the sand into the hopper of the machine, and then connect the air pipe to the air compressor. Turn on the switch, and the high-pressure gas generated by the air compressor will “push” the sand out of the nozzle. The high-speed moving sand hits the surface of the object and knocks off the rust, paint, and dirt.
- The wet sandblasting machine has an additional water tank, and the water will mix with the sand in front of the nozzle. In this way, the impact of the sand is softer and dust can be reduced, which is especially suitable for scenes that are afraid of dust.
How to Choose a Suitable Mobile Sand Blasting Machine?
Don’t worry about choosing a portable sandblaster machine, just look at three places.
- Look at the size of the work: for cleaning small parts and jewelry, choose a mini sandblaster; for processing iron doors and shelves, choose a regular model.
- Look at the working environment: choose a dry sandblaster machine for outdoor or well-ventilated places. Choose a wet sandblasting machine for indoor workshops or places where you are afraid of getting dirty.
- Look at the budget: YG’s mobile sand blasting machine for sale is very affordable, factory direct price, and has a variety of models. No matter how much your budget is, you can find a suitable one.
FAQs about the Portable Sandblaster Machine
1. What is the air consumption of the portable sandblaster machine? What size air compressor should I choose as an optional accessory?
Its air consumption is usually 4 to 6 cubic meters per minute at a pressure of 0.8MPA. We recommend an air compressor with a minimum output of 4 cubic meters per minute. The smaller the air compressor’s air output, the lower the sandblasting pressure. Conversely, a larger air compressor delivers higher sandblasting pressure and better working efficiency.
2. What is the working efficiency of the portable sandblaster machine?
A larger model does not equal faster efficiency. A bigger sand tank has a larger internal volume to hold more abrasives and supports longer continuous sandblasting time, so tank size has no bearing on sandblasting efficiency. This machine can blast about 20 to 30 square meters per hour. Efficiency mainly depends on the complexity of workpieces. Flat plates take much less time, while irregular parts greatly slow down the sandblasting speed.
3. How to match sand hoses and sand blasting guns?
There are two standard sand hoses: inner diameter 25mm, outer diameter 40mm, and inner diameter 32mm, outer diameter 50mm. Sand tanks under model 700 match the 40mm outer diameter hose; tanks model 800 and above use the 50mm outer diameter hose. Sand blasting guns come in sizes 6mm, 8mm, 10mm, and 12mm. 8mm or 10mm guns are the most commonly used options.
