To carry out anything professional you have to have good knowledge. While you are going with abrasive media blasting, it can be a must as a possible operator of your sandblast machine has to work together with several equipment. There are safeties and risks involved of which a worker must take great care. Some years back there was no professional training being imparted to the operators of sandblasting. People without prior training were hired and allowed to work as a sandblaster, Some individuals totally failed while trying, some were able to learn it by hit and trial method and several became real experts and continued thereafter.
In this particular tutorial article I have discussed in lengths about doing it sandblasting works.
a. Filling the machine properly:
Three or four sacks of abrasive medium can be held inside the concave head after filling the machine completely. These extra three to four sacks of sand enter the machine after it has become depressurized for refilling.
b. Offering a variety of hose sizes allows the operator to reach the inaccessible areas easily. Obscured areas where normal nozzles cant blast may be taken care of by use of angled nozzles.
c. Instructions on operating the air valves of sand blast machine:
1 . Prior to starting the machine be sure that bleed off valve have been closed.
2 . Following the step 1 air inlet valve is to be openned.
3. You must keep choke valve open at all times.
4. The instant you are shutting off the sandblaster, sand control valve is not at all to get touched, open the bleed off valve and simultaneously close the inlet valve.
d. Manipulate mixing vlave and control the abrasive’s flow:
It really is all good sense. Close the mixing valve in beginning gradually start opening the mixing valve then the pupose is always to see if proper mixture of sand and air is discharged from nozzle. Should you don’t adjust the mixing valve properly the abrasive being subtracted from nozzle will spit and feed without uniformity. Should you don’t want to buy to happen adjust the knob. In case you don’t see anything changing even after you might have opened the valve in various direction, it is really an indication of presence of moisture within the machine. In these instances a good self dumping moisture separator should be used.
e. How to attach hose to sandblast machine and couple it:
Length of the hose should be wisely chosen. Correct ratio is ID of the hose 3 X ID of the nozzle. If coupling is usually to be installed on the hose, the finish of hose should be square cut. This can help its correct fitting within the nozzle.
f. Caring about the nozzle:
Don’t cause damage to the nozzle. Do not use wrenches to attach or remove nozzles from the holder. Protect the liner and jacket from the abrasives by using new washer behind the nozzle each day. Slip a small piece of hose over the jacket to protect the nozzle from being cracked or broken.
g. Caring about helmet:
We all know that helmets are really expensive that is why they must be taken care of to elongate their life. Once the eye plate starts frosting over, it should be placed periodically. If your worker is not able to see properly, his rate of production will slow down hence it is advised that eye plate get replaced after set amount of time. You must also keep the airfed helmets clean.
h. Hose arrangement:
Any sharp bends should be removed prior operating the machine. Minimum amount of hoses are to be used. Keep the hoses dry. This helps you efficiently do your job.
