- Sand tank.
- Neck for pouring sand into the tank.
- Pressure gauge showing inlet air pressure.
- Compressor connection.
- Forming a mixture of air and sand.
- Air-sand mixture supply hose.
The principle of operation of the device is as follows: under high pressure, air is supplied from the compressor to a distribution point ( 5 ), where sand and air are mixed (for pressure types of sandblasting). from the tank ( 1 ). The resulting mixture goes through the hose ( 6 ) to the nozzle, which throws sand onto the workpiece. At the compressor connection point ( 4 ) there is an additional filter that filters the air from condensate so that the working mixture is dry.

Retirement brushes: which electric spray gun is best to buy for your home?
The design and operating principle of a sandblasting machine is very similar to a spray gun, with the only difference being the material used for surface treatment. A sandblaster is a pneumatic tool, so you will need a good compressor to operate it. If you already have a compressor for your car, you can use it.
Description of the device
These tools differ in characteristics and principles of operation. However, they contain identical structural elements:
- compressor;
- a gun with a nozzle;
- abrasive tank;
- control device;
- connecting hoses;
- storage receiver.
The most important element is the compressor, which serves to increase the pressure of the air flow. They are divided into low-power, medium-power and high-power units. The operation is controlled automatically, turning the device on and off, adjusting the pressure indicator.
The best and most expensive models are equipped with compressors and a special system that allows them to shut down in the event of a breakdown, as well as in the event of power surges.
The advantages of automation are as follows:
- Complete stop of the device if the operator’s hands lose sight of the nozzle.
- Possibility of switching the device into working and idling mode.
- Management of additional functions.
- When the sand level drops, it starts signaling.
What to look for when choosing a model? On the quality of assembly and dimensions of hoses for air and sand, as well as for removing the abrasive component. The device’s power and performance, as well as the quality and duration of operation, directly depend on these parameters.
Shutter types for adjustment
Sandblasters in most cases have shut-off valves or gates, which come in two types. Gate valves are used when using light abrasive materials. For example, sand, nickel slag or Cooper slag. These valves are inexpensive, but will not be suitable if you use heavy metal abrasive materials.
Valve valves – used in combination with heavy abrasive fillers. They allow precise dosing and very precise regulation of the amount of abrasive for cleaning. You can use either cast iron or crushed shot, or granite chips with a diameter of up to 4 mm.
Features and principle of operation
Sandblasting units are used to remove various types of contaminants from surfaces. Manufacturers produce several types of installations that are similar in principle: thanks to compressed air, an abrasive agent or sand flies out of the nozzle at great speed, crashing into the dirt and effectively removing it. These devices are used to clean buildings and metal structures from rust, old paint, dust and dirt.
Sandblasting is divided into types, depending on the type of action and power. Thus, the division occurs into the following devices:
Kinds | Characteristics |
Low power | The capacity of the container does not exceed 30 liters. Scope of application: hard-to-reach places and when carrying out work at significant heights. If you are unable to function for a long period of time, you must regularly give the device a rest. |
Medium power | Capacities from 50 to 140 l. They are distinguished by the absence of a powerful compressor. Used in medium and small industries. |
High power | Availability of a capacity of at least 20 liters. Used for significant volumes of work. This stationary device treats huge contaminated areas. |
Based on the type of action, devices are:
- Pneumatic (pressure). They quickly and efficiently deal with heavy dirt or thick layers of rust. We are ready to cope with any volume of work, which is why we enjoy deserved popularity at large enterprises. A distinctive feature of these devices is the following: compressed air enters not only the installation, but also the abrasive dispenser, which significantly increases the speed of the released air stream.
- Vacuum. The operating principle is as follows: an abrasive substance is applied to the contaminated base, immediately picked up by a vacuum and again thrown onto the contaminated area. May be used for certain activities that may cause damage to surfaces in the immediate vicinity.
- Injection. Distinctive feature: air and abrasive mixture are supplied through different hoses. The power of the unit is small, so the device is not able to cope with significant pollution over large areas. However, for delicate cleaning this is the most acceptable option.
Sandblasting treatment options
Thanks to such installations, it is possible to tidy up various types of surfaces using:
- Easy cleaning – removal of minor rust and scale. The result is a clean base, but some dirt may remain in hard-to-reach areas.
- Medium cleaning – involves more thorough measures to remove paint, dirt and rust. Result: there remain pinpoint areas covered with corrosion.
- Deep cleaning, providing ideal cleansing of all kinds of contaminants. It is used if the next stage of work is to apply paint and varnish.
Types of installations
Sandblasting machines are available in two types, the differences between which are indicated in the comparative table:
What are there | Description |
Open type | They are used in open spaces: under awnings, on the street, and so on. Inexpensive, mobile, with minor parameters. The main disadvantage is that a lot of dust appears during operation, there is no way to collect and reuse the abrasive mixture, too much sand is wasted. Working with the tool is quite dangerous, so the operator must wear full protective equipment. |
Closed type | They are used in a closed space - a special chamber with different dimensions: from a small box to a large room. The devices have significant power, with circulation of the abrasive mixture, allowing it to be reused. Widely used in the construction of large projects and rarely at home. Safer to use. The main disadvantage is its considerable size, difficulties during transportation and the requirement to connect to ventilation systems. |
Popular models may also be:
- Stationary. Installed in production workshops. Equipped with a built-in filtration system, connected to powerful ventilation systems, they are used for processing individual objects and parts, as well as small surfaces.
- Mobile. As a rule, they are small-sized or homemade, made independently at home, using step-by-step instructions provided on the Internet. They can be used to process tanks, large equipment, building facades, and so on. Moved to a specific location, depending on the need.
Classification
Today, two classifications of sandblasters are offered. The first classification divides the device into three types according to where it is used:
View | Description |
Pneumatic | Due to their high power, pneumatic machines are used to process huge structures. |
Vacuum | In vacuum versions, the abrasive is first thrown out, and then the abrasive material is drawn back in by vacuum and is subsequently used again. This device can be used to decorate small areas. |
Suction | From the container, the abrasive enters the nozzle with the help of air. This sandblasting machine can remove paint and frost glass. |
Another type of classification is based on the method of supplying the abrasive:
View | Description |
Injection | Two sleeves - each for feeding a separate component. Two nozzles – abrasive blasting and air. The jet speed is lower, which means this type is suitable for small-scale work. |
Pressure | One sleeve, one nozzle. Air and abrasive are together from the very beginning to the very end. This allows for a significant increase in the feed rate of abrasive material. |
There are a large number of different classifications
Areas of application of sandblasting devices
The most common industry is body repair. This technique helps to quickly and effectively remove old paint, rust, grease and other contaminants from the surface. The device is often used when repairing disks: if a part is peeling, dented or damaged, then before starting to restore it, they first carry out high-quality cleaning, and then paint.
What are the advantages of a sandblasting unit? The result of metal grinding with this tool is unique, which cannot be achieved manually. This method removes even the most pinpoint elements of corrosion “hidden” in pits, minor pores and microcracks, which allows minimizing the rusting process of the metal base. Products cleaned in this way last much longer and are less susceptible to corrosion. As for the surface, it turns out surprisingly smooth. If there are no scratches, the primer and paint cover the parts perfectly.
In addition to car repairs, sandblasting devices are widely used in:
- furniture production;
- ship repair and shipbuilding;
- during major repairs of construction projects;
- wood processing industry;
- when cleaning foundations from brick and concrete;
- in the process of metal engraving;
- creating intricate patterns on glass;
- pre-treatment of products before applying thermal spraying and the use of galvanic operations;
- when matting ceramics and glass.
Powerful devices made of high-strength material and endowed with special functions through the use of various attachments are used for drilling holes, grooves and grooves. Designer imagination using such a unit allows you to treat the surface in such a way that the material “ages” and acquires a vintage look.
Self-production of sandblasts
You can make sandblasting yourself. A diagram of a sandblasting machine can be found on the Internet. You need to carefully study it to understand the design, fastening elements, and dimensions. Knowing the elements of a sandblasting installation, you can begin preparing materials and tools. After studying the drawing, you need to prepare for assembly:
- You will need a container in which to mix the abrasive with air. An empty gas cylinder will do.
- A compressor to pump up pressure with a maximum power of at least 8 atmospheres.
- Four ball valves.
- Gas hose 5–6 meters long, diameter 1 cm.
- Fum tape to improve connections.
- Pipe sections.
- Rubber hose 3 meters long, diameter 1.4 cm.
- Collet clamps.
- Sandblasting nozzle.
- Fittings with which the hoses will be secured.
- Pressure meter.
- Tees to which hoses will be connected.
The tools you will need are a grinder, a welding machine, a hammer, a set of keys, and screwdrivers.
Stages of assembling homemade equipment:
- Prepare an empty gas cylinder. To do this, you need to cut out the tap through which gas will be supplied. This can be done with an electric drill with a metal drill. There are many holes around the tap. The finished hole needs to be made round, and a piece of threaded metal pipe welded into it. Treat the welding shock with a grinding machine and a protective coating. A suitable cap is screwed onto the thread. This hole will be used to fill the abrasive.
- Another hole is made in the center of the bottom of the cylinder. You need to weld a piece of pipe into it, with a tee attached to it. Threaded connections are strengthened with fum tape.
- On the side surface of the cylinder, closer to the place through which the abrasive material will be poured, a hole is made through which air from the compressor will be pumped. A pipe with a tee at the end is welded into the hole.
- Next comes the connection of key elements. For this purpose, hoses and clamps are used to crimp the connections.
In order not to make a cumbersome installation, you can assemble a small apparatus for applying paint and decorative surface treatment. To do this you need a gun, a simple compressor, a bottle, a metal tube, a bottle cap with a hole for the tube. Assembly:
- Fill the bottle with paint and fine abrasive powder.
- Make a system from a metal tube through which air from the gun will lift the contents of the container and bring it out.
- Check the connection, connect the compressor.
Experts do not advise making pressure-injecting installations yourself.
Advice from experts on working with sandblasting
It does not matter which company is better to purchase the product, and whether it is in the rating of quality products, Russian or Chinese production, budget or at a significant price. The main condition of work is compliance with safety regulations. A branded tool can cause harm to human health, causing the development of serious pulmonary diseases, or lead to injury due to the significant speed of abrasive ejection from the nozzle.
To avoid unpleasant situations and maintain your health, you need to listen to these recommendations:
- Before work, wear closed shoes made of thick material.
- Don’t forget to wear a high-strength special overall.
- Wear a protective helmet.
- Protect your hands with leather gloves.
Some “daredevils” wear only a regular respirator when outdoors, but the best option would be to have a helmet with an autonomous air supply. If actions are performed indoors, then this attribute is mandatory.
It is worth considering that powerful units are not silent, therefore, in order to avoid damage to the hearing organs, it is worth wearing headphones with sound-absorbing functions under the helmet. Can also be built into a helmet.
Features of premises for working with the unit
The effectiveness of any work directly depends on the correct organization of the workplace. Sandblasting will function safely and reliably in a room with normal humidity levels. Otherwise, the process may be significantly delayed and productivity may decrease. If the humidity is too high, measures are taken to reduce the indicator. For these purposes, special dryers are installed at the facility. The best manufacturers produce popular models equipped with such functionality.
Air purity is of great importance. This is achieved through the use of filtration systems. As a rule, they are already built into the devices, which makes it possible to free the air from particles of dust, dirt, and oil. If the device operates in a closed space, then the object must be able to quickly and efficiently be cleaned of sand. The best option is to completely seal the room, where the remaining sand will fall into special tanks through holes made in the floor. After preliminary sifting, it can be reused.
Compressor performance calculation
Performance is perhaps the most important characteristic of a compressor - the volume of air compressed per unit of time. Air is the most important element in sandblasting, so it is important to select a compressor with a small capacity reserve.
The best option is to display an air flow rate equal to 70-90% of the maximum compressor performance. In the compressor passport, the performance value is always indicated, but there is a formula for checking:
Q=(Q1*Ki1+Q2*Ki2+Q3*Ki3+...+Qn*Kin)*Kc, where: Q is the required compressor output capacity, Q1...Qn is the air flow rate of each consumer, Ki1...Kin is the utilization factor of each consumer, total: Kc - equipment synchronism coefficient.
How to choose a device
According to buyers, it is necessary, first of all, to pay attention to the weight of the product. The design should not be heavy. In addition, it is advisable to equip it with a chassis to facilitate transportation. As for the tank, its characteristics must meet international safety standards. When purchasing, you need to request an inspection certificate from the seller.
Which product is better to buy depends on the preferences of the master. But there are certain selection criteria that must be taken into account. Moreover, the brand and rating are not fundamental. The design of the pipeline is of great importance. It is worth keeping in mind that the simpler it is, without fittings and bends, the more powerful the unit. You need to pay attention to the diameter of the hole. The optimal figure is 32 mm or more.
In order to avoid mistakes when choosing, it is necessary to review the products and read the reviews. It is necessary to pay attention to the following points:
- ability to function with different granular materials;
- high assembly reliability;
- the presence of an automatically closing filling valve or damper;
- presence of a feeding container;
- equipped with an abrasive material dispenser, shut-off valves for air inlet and outlet;
- presence of an inspection hatch.
For a powerful compressor, a nozzle with a large diameter is assumed. This is the only way to increase productivity. To choose the right air gun, you should pay attention to the following recommendations:
- processing of wood, brick or concrete is carried out by a unit with high productivity, but low jet power;
- It is better to clean metal and glass with a strong jet of abrasive.
There are several ways to purchase a device of this type: through one of the many online stores (order online) or delivery directly from China via the Ali Express online resource. You can also contact a specialized store, where you can then arrange the purchase of the selected equipment. The last option is advantageous in that the sales manager will help you make a choice, tell you about new products, give certain recommendations, and provide quality certificates.
A person with certain skills and tools can make the device with his own hands. The Internet will tell you how to build your own version. Let the unit not be too powerful, but it will provide significant assistance during repairs.
Basic options to choose from
Based on experiments, it has been established that in order to process a metal surface with an area of several square meters, it is necessary to provide a continuous supply of an abrasive jet mixed with air weighing 0.05...0.07 kg/s. The volumetric ratio between sand and air is (0.01...0.012):1. It turns out that to supply sand you need 100 times more air volume.
To provide such an amount of compressed air, the compressor performance must be 12...15 l/s (720...900 l/min). An important parameter will be the pressure created by the pneumatic machine.
In the theory of gas flow through a nozzle, the formula is used:
, m/s
Where:
- k – adiabatic index. For diatomic gases (a gas mixture of nitrogen and oxygen is a mechanical compound of diatomic gases) k = 1.4;
- pcr – critical gas pressure in front of the nozzle, bar;
- p₁ – pressure of the ambient gas into which the outflow occurs, bar;
- v₁ – specific volume of air, kg/m³.
To clarify the critical pressure, use the formula:
For diatomic gases, the critical value is βcr = 0.528. In a conventional expanding nozzle, it is impossible to achieve speeds greater than the speed of sound for a given gas at the appropriate temperature. Therefore, talk about the need to have high pressure at the nozzle inlet is unfounded.
At excess pressure pcr = 2.1...2.2, an air flow velocity equal to wcr = 290...310 m/s is achieved. To obtain a higher exhaust velocity, expanding Laval nozzles are used. But when they work, a sound similar to gunshots will come out. It will be extremely dangerous to be near such a working installation; your eardrums will not withstand it.

Sandblasting or shot blasting?
It is worth noting that, paradoxically, sandblasting equipment/apparatuses can easily be called shot blasting equipment/apparatuses. Specialists will understand what’s going on (the principle of operation and the result are the same), but the average person, a non-specialist, can be seriously stumped because of the difference in names.
Geography of supplies of shot blasting, sandblasting chambers and shot blasting equipment: St. Petersburg, Moscow, Ryazan, Kazan, Izhevsk, Samara, Yekaterinburg, Chelyabinsk, Kaluga and many other cities of Russia.
You can always buy a shot blasting chamber of the required performance and configuration from the Aox company.
