Abrasive blasting machine. Sandblasting Technology

The implementation of abrasive, cleaning and grinding operations is increasingly associated with the function of abrasive blasting equipment. Traditional adaptations and tools are receding into the background, giving way to productive aggregates. In the domestic market, machines of this type are available from different manufacturers, but Contracor takes the leading position. Even in medium modifications, the abrasive blasting machine of this manufacturer is able to perform high-quality processing of various surfaces. However, with this product range of offers on the market is not limited.

Varieties of technology

At this stage of development of this direction, manufacturers offer three options for installations - pneumatic, injector and vacuum. The most attractive in terms of power and efficiency is the pneumatic unit. Such machines are usually used in the industry when it is required to maintain a large area. Injector models can be called the opposite of the above-mentioned type. These versions work by the type of suction of abrasive from a special tank, after which the crumb is fed by air to the working surface. Injection abrasive blasting apparatus is characterized by low power, and therefore it is used in the solution of simple tasks of stripping and grinding. As for 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 already thrown out abrasive, providing also economy of money resources.

Main characteristics

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

Model "Sorokin 10.3"

Domestic version of a small, but functional sandblast. The volume of the tank is only 34 liters, but it is enough to perform cleaning operations in the car repair shops, and even more so in the private sector. Except for the difference with the more voluminous analogues in the capacity of the loading tank, the abrasive blasting machine of Sorokin will benefit from the versatility of the application.

The fact is that the power of this unit is sufficient for servicing metal structures. For example, with its help, such surfaces get rid of rust, scale and obsolete paint and varnish. But, in addition, the model is suitable for neat maintenance of non-metallic surfaces up to thick glass.

Models of the DBS line from Contracor

In this case, we are talking about a more productive technique, presented in different designs. In the initial segment, the company offers an 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 tank of 100 liters, so the workflow can not be stopped until the operation is completed. However, this depends on the amount of work planned.

Modification with a tank of 200 liters is already exactly suitable for solving problems on an industrial scale. Of course, the DBS 200 abrasive blasting machine is not cheap, but its function will justify the investment, if it is necessary to quickly update the massive structures. At the same time, both versions of sandblasters from the DBS family are characterized by high productivity, reaching 37 m ² / h. Promotes effective performance of various tasks and the possibility of using sand with a fraction of the order of 3.5 mm.

DSG models "VMZ"

Vyksa Steel Works offers sandblasting units of the DSG series, which, according to users, are reliable in performance, functionality and quality of processing. The unit uses compressed air, which is pre-filtered from oil and moisture. It is the preparation of load-bearing masses that allows the equipment to remain operative even in difficult operating conditions. According to the characteristics of the abrasive blasting apparatus DSG is similar to previous versions, but there are differences. First of all, it concerns the possibilities of working with abrasive. In the bunker, which in the average version has a volume of 200 liters, it is possible to load sand of a fraction of 2 mm. But it can not be said that the fine fraction of the consumable material in this case causes a lack of technology. Restriction on the size of the abrasive only determines the direction of use of the unit - mainly these are more delicate operations, close to the grinding procedures.

Conclusion

The technique for sandblasting is expensive, and therefore it should be chosen with the utmost responsibility. To rely on this event is on the primary characteristics, as well as on the design features. For example, the abrasive blasting machine 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 is operated in the same place on the production line, then there is no need for such an addition. But you should carefully approach the selection of components. Injectors, couplings and adapters cause the possibility of blasting sandblasting with compressors and exhaust pistols. It is important to take into account the requirements of technology in terms of energy supply. Recently, more and more often on the market are autonomous models, provided with stabilizers and protection systems.
