Abrasive blasting apparatus. Sandblasting Technology

The performance of peeling, cleaning and grinding operations is increasingly associated with the function of abrasive blasting equipment. Traditional fixtures and tools fade into the background, giving way to production units. In the domestic market, machines of this type are available from different manufacturers, but Contracor is the leader. Even in medium-sized versions, the abrasive blasting apparatus of this manufacturer is capable of performing high-quality processing of various surfaces. However, the range of offers on the market is not limited to these products.

Varieties of technology

At this stage of development of this direction, manufacturers offer three options for installations - pneumatic, injection and vacuum. The most attractive in terms of power and efficiency is a pneumatic unit. Such machines are usually used in industry when it is required to service a large area. Injection models can be called the opposite of the above type. These versions work by the type of abrasive suction from a special tank, after which the crumb is supplied with air to the working surface. The injection abrasive blasting apparatus is notable for its low power, which is why it is used in solving simple problems of cleaning and grinding. As for the vacuum models, they are also not used in large-scale events, but they have one advantage. Models of this type allow several times to use the already thrown abrasive, providing money savings.

Main characteristics

In assessing the working potential of sandblasting plants , two characteristics are taken into account - the productivity and volume of the tank, which is pre-filled with an abrasive mixture. The performance indicator is expressed as the volume of particles ejected by the apparatus with air per hour. Models of entry-level aggregates provide about 3-5 m 2 / h. In workshops and on construction sites, equipment is more often used that produces about 10-15 m 2 / h. The most productive modifications are capable of producing up to 30 m 2 / h. At the same time, the volume of the tank is on average 20-40 liters. True, in large industries you can find an abrasive blasting apparatus, to which a capacity of several hundred liters is supplied. These are massive structures, which are often part of the production lines.

Model "Sorokin 10.3"

The domestic version is small in size, but functional sandblasting. The volume of the tank is only 34 liters, but it is enough to perform treatment operations in auto repair shops, and even more so in the private sector. Except for the difference with more voluminous counterparts in the volume of the loading tank, the Sorokin abrasive blasting apparatus will benefit from the versatility of use.

The fact is that the power of this unit is enough to service metal structures. For example, with its help, such surfaces get rid of rust, scale and obsolete paintwork. But, besides this, the model is suitable for accurate maintenance of non-metallic surfaces up to thick glass.

DBS Models by Contracor

In this case, we are talking about a more productive technique, presented in different versions. In the initial segment, the company offers the abrasive blasting machine DBS 100, which is suitable for use in agriculture, in domestic needs, as well as in car workshops. The unit has a 100 liter tank, so the workflow can not be stopped until the operation is completed. However, it depends on the volume of the planned work.

The modification with a 200 liter tank is already exactly suitable for solving problems on an industrial scale. Of course, the DBS 200 is an abrasive blasting machine and is not cheap, but its function will justify the investment if you need to quickly update massive structures. At the same time, both versions of sandblasting from the DBS family are characterized by high productivity, reaching 37 m 2 / h. Contributes to the effective implementation of various tasks and the ability to use sand with a fraction of the order of 3.5 mm.

Models DSG "VMZ"

Vyksa Steel Plant offers sandblasting machines of the DSG series, which, according to users, are distinguished by their reliability, functionality and quality of processing. Compressed air is used in the power supply of the unit , which is pre-filtered from oils and moisture. It is the preparation of the bearing mass that allows the equipment to maintain operability even in difficult operating conditions. According to the characteristics, the DSG abrasive blasting machine is similar to previous versions, but there are also differences. First of all, it concerns the possibilities of working with an abrasive. In the hopper, which in the average version has a volume of 200 l, you can load sand fraction 2 mm. But it cannot be said that the fine fraction of the consumable in this case causes a lack of technology. The restriction on the size of the abrasive only determines the direction of use of the unit - mainly these are more delicate operations, close to grinding procedures.

Conclusion

Sandblasting equipment is not cheap, therefore, it should be chosen with utmost responsibility. Relying on this event is based on primary characteristics, as well as on design features. For example, the abrasive blasting apparatus DBS and other named modifications are equipped with a running gear with wheels. But mobility is not always the criterion of choice. So, if the unit will be operated in the same place on the production line, then there is no need for such an addition. But then you should carefully approach the choice of components. Nozzles, couplings and adapters determine the possibility of interfacing with sandblasting compressors and exhaust guns. It is important to consider the requirements of technology in terms of energy supply. Recently, autonomous models provided with stabilizers and protection systems are increasingly entering the market.
