Shot blaster
The shot blasting machine and the shot blasting equipment are using sand blasting technology usually. These are the first technology discovered in this field and the people manufacturing shot blasting machine and the shot blasting equipment were using the sand blasting technology in it. But as the technology advances the people came to know about other technologies too which can be very much effective to use too. The people came to know that how the cleaning and etching on a surface can be made more efficient and so did the people came to know everything about that and made sure that the latest will overcome all the drawback of the previous technology.
The airless shot blaster is the new invention in this field and is proving to be great in deed. The people are happy to use the airless shot blaster because it does not makes any dust particles in the air and its technology is totally different to the sand blaster. The airless shot blaster has a spinning wheel and it sling the shot at high speed at work pieces. And no air pressure is done in this process at all.
The airless shot blaster uses the steel shots and this makes the surface even more cleaner and neater and if the etching process is suppose to be taken with the airless shot blaster than you will really found the great etching done on the required surface. The steel is very sharp and can make the thing go brand new and look extremely awesome too. The airless shot blaster has come into the field with such a great change that the people really like the thing and uses it with a lot of joy too.
The airless shot blaster has made the cleaning of surfaces too easy and has also made the etching process more easy and more sharp. The edged of steel are just too much pointing that the etching is done very easily and with a great pleasure too. The airless shot blaster is now mostly used and the people like to buy these blasters to make the work more efficient and fast.
People always are in search of convenience and when people find the convenience in the airless shot blaster than people just rush towards it. Obviously who will go for the toughest jobs to do people always go for the better and the better.
Blasting sand
In shot blasting machines and all other shot blasting equipments the blasting sand is used as a material. This blasting sand material helps to etch or clear the surface with the help of shot blasting machines and the shot blasting equipments. But as we all know that the blasting sand can be very hazardous to health and this is because the people in the world are making use of it at very large scale and due to this reason the people in past are really very much affected by them too.
Due to this problem the people in this world have made it sure that they will make such type of machines and equipment that will work too and will not harm the health of a person. The lungs are the major part that really got affected by the blasting sand. And so the cancer of lungs really occurs and people die soon. So to overcome this problem people started to find the better way of making the blasting equipments so they may not cause any damage to the health.
The blasting sand is now used as a material in machine along with some other material like coconut so that the air to breathe while using that equipment can be adjusted and the people may not get the lungs damaged at all. The blasting sand is also used with many other materials like the wall nut shells and powdered abrasives, copper slag and the grits too. All these things make the blasting sand to not to inhaled by the air that they will be breathing in. The blasting sand would have been very much hazardous to the health if the people keep on using it the way they used to. And if this problem remained there the people will never agree to use those equipments as they all would have been died by now.
The blasting sand with these material is such a perfect thing to use because the etching and the cleaning is done so well and the people has also realized that the lungs and all other health diseases that might have caused by them will now be cured easily as they are not damaging the lungs at high scale at all. A cough problem may be seen but nothing more than that. So the blasting sand is proved to be great in deed and material along it has made the things to go greater.
Most commonly used shot blasting cabinets
For sandblasting we use different shot blasting machine, depends on what type of sandblasting we want to do. Many bigger companies who work with sandblasting use many portable shot blasting equipment, because majority of work is on the field. But they also use few shot blasting cabinets, normaly they have them stationed in their main workshop. These shot blasting cabinets are being used for smaller items because they are normally closed during work.
This type of sandblast is a lot less hazardous for workers because shot blasting cabinets are build in a way that they suck all dust away. The side effect of this is that you are limited with size of items, if you can’t fit it into shot blasting cabinet you cannot blast it. Luckily there are many variations of shot blasting cabinets, from smaller cabinets to huge, few meters wide and high cabinets.
Different shot blasting process
There are few different types of shot blasting process. Since we don’t always want to have same final effect we have to use different types of media for that. Type of shot blasting process only varies based on what type of media is being used by shot blasting machine.
Most commonly used media for shot blasting process is sand. We can use different size of sand to get different effects. Apart sand we can also use other media such as chilled iron, garnet, glass beads or olivine.
Some media are used abrasively and are used to clean surface and remove for example paint or rust. Other media are being used in shot blasting process to just polish the surface or to chemically change the structure of item so it can be made more robust.
Sandblasting abrasive is developing
In the past for sandblasting was using only sand abrasive but now in 21. century the abrasive technique is developing so now there are a variety of different materials in use depending on job that should be done. There can be used a lighter sandblasting abrasive for minor jobs like walnut husks. For heavier tasks is suitable more aggressive sandblasting abrasive like beads. With a wide range of abrasives the jobs can be done with better results. Sifted sand was traditionally used as a main sandblasting abrasive but now is losing the importance because of the dust that is released when sand is blasted onto surface and can be toxic. Using of sand requires protective clothing. With using more soft sandblasting abrasive the more sensitive surfaces remains without damage. For thick layers is very suitable silicon carbide that is strong enough to perform even the hardest tasks.
Shot blasting machine
Like sandblasting also shot blasting is used in many ways.
Therefore there are different and many types of shot blasting machine. Some of them asre specialized for one thing and one item while others are specilized for sompletly other part.
For extruded aluminion there is specialized shot blasting machine that will give satin etched to profiles and it will also remove extrusion lines on profiles.
Then we have specialized shot blasitng machine for pipes. These machines are used to clean the pipes.
There are many different types of shto blasitng machine, degigned and usef for their specific tasks.
Sandblasting equipment
Like shot blasting also sandblasting requires specialized equipment for work. And since sandblasting and shot blasting are quite alike we can use same equipment for work with both, at least vast majority of it.
Sandblasting equipment mainly consists from machine, abrasive, hoes and gun with nozzle.
When we buy new part of sandblasting equipment we buy piece that suite our needs most. Market has enough diferent models in almost all shapes and sizes so we can really use the one that is best for us.
For example, if we mainly work in firm we can use bigger machine and less hoes. With bigger machine we can normally also use bigger gun and also bigger nozzle. But we can’t do the same if we work on the field. In there mobility ist the key, so having smaller machine and other part of sandblasting equipment makes us one step ahead from competition.
