How to Use Sandblasting Machine Safely

As we all know, sandblasting machine must be maintained after a certain period of time, so as to ensure its service life and the effect of sandblasting. If it is without maintenance, there will be a lot of problems when using it. Let me give you an example: Weak sandblasting will occur because the sandblasting pressure must be greater than 0.7MPa. Here we will talk about today's topic:  precautions for use and safe operation specifications of sandblasting machine!


As a conventional abrasive jet technology, sandblasting equipment has been developing, upgrading and improving all the time. Due to its special processing mechanism, ordinary processing and use boundaries, sandblasting machine is more and more favored in the current surface treatment industry, and it has been commonly used in machinery manufacturing, instrumentation, medical equipment, electronic appliances, textile machinery, printing and dyeing machinery, chemical machinery, food machinery, equipment, cutting tools, measuring tools, molds, glass, porcelain, handicrafts, mechanical repair and so on.


Wear protective equipment before work. Working with naked arms is forbidden and no less than two people should be at work. The air storage tank, pressure gauge and safety valve shall be checked regularly. Dust should be discharged from the air storage tank once every two weeks, and the filter in the sand tank shall be inspected once a month.


Check whether the ventilation pipe and sandblasting machine door are sealed. The ventilation and dust removal equipment must be started five minutes before the work. If the ventilation and dust removal equipment fails to work, it is forbidden to start the sandblasting machine.


The compressed air valve shall be opened slowly, and the air pressure shall not exceed 0.8MPa.


The particle size of sandblasting shall be suitable for the working requirements, which is generally between No.10 and No.20, and the sand shall be kept dry.


When sandblasting machine is working, irrelevant personnel are forbidden to approach. When cleaning and adjusting the operating parts, the machine should be stopped.


Do not blow dust or joke with compressed air.


After the work, the ventilation and dedusting equipment should continue to run five minutes before being turned down to discharge the indoor dust and keep the site clean.

In case of personal and equipment accidents, keep the site and report to relevant departments.
