For that reason, we decided to create a guide that could help anyone else out there who is having the same question.<\/p><p>Before doing anything it should be established that aluminum oxide is the right media for the surface you need to prepare. Also, you need to make sure that the equipment you are going to use is ideal for aluminum oxide.<\/p><p>With these 2 answers down, it is time to get to details.<\/p><p>So, as you can see, is not just a matter to get the media and start blasting.

If is a wet blasting operation, in this part of the cabinet the media will dry, before joining the rest of the abrasive in the media container.<\/p><p>Since aluminum oxide does not rust, the media getting wet is not a problem, but in the case of many other abrasives, drying it before putting it together is essential to avoid contaminating the surface to be blasted.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b7cb5d0 elementor-widget elementor-widget-shortcode\" data-id=\"b7cb5d0\"

small area of the surface to be treated. The reason behind the need for this test is to calculate the blasting time, abrasive media, and repositioning or recovery time that the full operation might take.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5a1f858 elementor-widget elementor-widget-heading\" data-id=\"5a1f858\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">The time calculation<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-cb545ec elementor-widget elementor-widget-text-editor\" data-id=\"cb545ec\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>The first thing to calculate is how much time will the whole operation take. So, count how much time you need to blast a small area of the surface. With that number in mind, determine what percentage represents the proportion of the small area you just blasted and what is the size of the total surface. With these figures, you will do a simple rule of three.<\/p><p>As an example, let\u2019s say that you spent 10 minutes blasting the small area you chose for the test. You know that the total size of the surface is 300 square feet. You calculated that the tested area represents 5% of the total surface, which equals 15 square feet. Now, you multiply 10 (minutes) by 300 (feet) which totals 3,000. Now, divide that by 15 (feet) and you will have as a result 200, which is the number of minutes you will need to complete the job. That equals 3 hours and 20 minutes.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-85f4199 elementor-widget elementor-widget-heading\" data-id=\"85f4199\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">The media calculation<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3d2d39a elementor-widget elementor-widget-text-editor\" data-id=\"3d2d39a\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>One of the good things about abrasive media is that they are not perishable goods. You can have as much as you want in your warehouse or plant, for a long time, and is going to be good.<\/p><p>So, depending on the blasting operations that you usually have, it is convenient to have enough abrasive media to blast for a long time without the need to recover. Again, you will need to calculate that in the test.<\/p><p>Once you finish blasting in the test, take a look at your media cabinet. How much media was consumed? A 5%? A 10%? Following the example, with the surface, you can also do a rule of three to know when you will need to stop to recover media from the ground.<\/p><p>Of course, this calculation is not needed if another operator is recovering media as soon as is blasted.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-15488ec elementor-widget elementor-widget-heading\" data-id=\"15488ec\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">The rest of the calculations<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-0566ae5 elementor-widget elementor-widget-text-editor\" data-id=\"0566ae5\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>Depending on the facilities you are using for sandblasting the media recovery might vary. For that reason is equally important to calculate how much time could take.<\/p><p>For instance, if two operators are involved in the blasting process, one of them is going to blast while the other is going to recover. The media recovery time there is close to none. But it is only one operator doing the job, he will need to stop now and then, depending on how much media he has available, to recover what he just blasted. This can take valuable daytime.<\/p><p>Another detail that can improve drastically the sandblasting operation is having a nozzle with a trigger system. That way the operator can start and stop right whenever he needs to. If the nozzle in use has not a trigger system, the operator might need to walk all the way down to start and stop the blasting operation, which can consume precious time.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-17bf161 elementor-widget elementor-widget-heading\" data-id=\"17bf161\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Step 4: Blast the surface in an efficient way<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-0cfd8a1 elementor-widget elementor-widget-text-editor\" data-id=\"0cfd8a1\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>Even though it might look like a chaotic operation, sandblasting should be done in a very methodical manner. So, yes, definitely there is an efficient way to do it.<\/p><p>Start by double-checking that the blast nozzles are configured correctly for current air pressure and volume. Once you are sure of that, start blasting the difficult areas within the surface, like curves or bumps.<\/p><p>The operator must make an effort to achieve the surface profile defined in a methodical way. Depending on the conditions of the surface this can be done at a speedy or slow pace. If blasting outdoors the weather conditions will also influence the way the operation is carried out. Never go against the wind.<\/p><p>When talking about efficiency at sandblasting we need to take into consideration too the conditions for the operator. They must have appropriate personal protective equipment which includes ears and eyes protection. They also should use masks to protect themselves from the dust cloud formed in the area. Only by sandblasting in a healthy and safe way, we can ensure the operators will be able to keep doing it day in and day out.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5a72c00 elementor-widget elementor-widget-heading\" data-id=\"5a72c00\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Step 5: Recover the media and get ready both equipment and media for the next blasting session<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f7f713e elementor-widget elementor-widget-text-editor\" data-id=\"f7f713e\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>Most continuous sandblasting operations count on two operators in place in order to recover the media as is blasted. In other cases, only one operator is available, so he himself sees the need to stop his blasting to recover the media in the ground.<\/p><p>In the case of aluminum oxide, which is our example in this article, since it does not oxide can be used immediately after being recovered, when wet blasting, without the need for any downtime to dry. Another advantage is that the dust cloud is less, so the downtime to recover is also lower, because the environment is not so polluted.<\/p><p>Now, in the case that you decided to go with other abrasive media (or actually is needed, due to the type of surface) this downtime for recovery might vary. Any media that can be recycled will imply some recovery time that has to be included in your cost calculations.<\/p><p>Immediately after the sandblasting, the surface must go to painting. This will prevent the surface from oxide again, and having again the need to be blasted.<\/p><p>Blasting equipment, whatever the size and capacity, are expensive. Make sure that the operators or specialized personnel take care of the one you own, by cleaning it immediately after each use. A regular maintenance program should be put in place to ensure a long equipment life.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-8d60058 elementor-widget elementor-widget-heading\" data-id=\"8d60058\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">You are not alone in this<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5facbb1 elementor-widget elementor-widget-text-editor\" data-id=\"5facbb1\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>In a summary, the five steps to prepare surfaces with aluminum oxide are:<\/p><ul><li>Step 1: Prepare the area and the surface to be blasted<\/li><li>Step 2: Choose the right blasting, media, and recovery system equipment<\/li><li>Step 3: Test in a small area<\/li><li>Step 4: Blast the surface in an efficient way<\/li><li>Step 5: Recover the media and get ready both equipment and media for the next blasting session<\/li><\/ul><p>These steps do not vary if you have a lot of experience in sandblasting.
