Efficiency Comparison Between Sandblasting Devices & Shot Blasting Devices

sandblasting machines and then shot blasting devices are considered as the mechanical processing of surface treatment techniques. Normally speaking, sandblasting machines coupled with shot blasting machine can both remove the rust or grease on the work piece together with guarantee the roughness requirements of the following procedure. Nonetheless, sandblasting machines and additionally shot blasting devices are of their own positive factors together with disadvantages. Sandblasting Machines Sandblasting devices work by compressed air to inject the sand materials on the surface of work pieces. In this way, the rust can be removed and then the surface can have certain roughness. Sandblasting is mainly used for removing the rust or oxide coating on the work pieces, especially pieces after heat treatment. sandblasting equipment can remove not just the rust, but also the grease on the surface of the work pieces. Among all the current surface treatment ways, sandblasting machines can have comparatively better cleaning effect. Sandblasting is suitable for those work pieces which have higher surface requirements. Yet, the in most cases applied sandblasting system is made up of many original heavy sand transport machines such as scraper and additionally bucket conveyer. Therefore, a deep pit and also waterproofing layer will be needed to install the whole sandblasting system. This project involves high construction cost, huge quantity of maintaining work and additionally high maintenance cost. What's worse, the sandblasting devices generate a number of dust during the operation, which might result in occupational disease of the personnel around and bring serious pollution to the environment. Shot Blasting Machines Shot blasting machine works by throwing the high speed running shots on the surface of the work pieces with centrifugal forces. Shot blasting machine is of much more functions compared with sandblasting machines. It can remove the rust or oxide coating, improve the roughness level of the surface, remove the burrs of the parts, eliminate the inner stress of the parts, prevent the parts after heat treatment from deforming and then improve the weariness resistance ability compressive capacity of the parts. Compared with sandblasting machines, which is mostly operated by manual force, shot blasting devices can be operated automatically or semi-automatically. The installation and also maintenance of shot blasting machine is also pretty simple and then cost effective. Shot blasting machine can provide perfect surface treatment to the work piece without changing its original shape and then thickness. Since shots are the leading materials of the shot blasting machine, there will be no dust or any other styles of pollution generated from the shot blasting process. Therefore, shot blasting machine is far and widely applied in many various industries, for instance, automobile manufacturing industry, ship manufacturing industry, steel industry and casting industry.Read more
