How does a blasting cabinet work

Your decision should come down to Wet or Dry Blasting, Siphon or Direct Pressure, the compressed air usage, the need for a machine from Light Duty to full Industrial Production, and the type of abrasive to be used for what you are cleaning. Pro Tip: Think about blasting cabinets like vehicles. There are vehicles for city trips and easy parking, vehicles to make you comfortable on long trips with family, and vehicles to pull 40, pounds across country day after day.

They all have their own applications. When you first Google Sandblasting Cabinet you may find lots of large tool suppliers with ads for blasting cabinets you would use at home if you are simply buying budget. They are pointed at selling you what you want, low cost blasting cabinet that operates using that 6 cfm compressor you pump up your tires with.

This mixing chamber largely determines, together with the gun combination and air injectors, how well and efficient the blast cabinet can work. Applications of an injector blast cabinet are cleaning, rust removal and deburring, matting, roughing and decoding of surfaces. The main advantage of an injector blast cabinet is that the cabinet requires lower investment and that it can be blasted for a long time without delay. The air consumption is also lower in this cabinet litres per minute at 6 bar blast pressure.

Always make sure that you use dry compressed air for blasting work. We advise you to connect a freeze dryer to your compressor. In a nutshell: Choose an injector blast cabinet for slightly less intensively treated surfaces.

An injector blast cabinet is cheaper to buy, but the blasting takes a little longer. Based on the above guidelines, you can distinguish between the types of blast cabinets in order to choose one that applies to your specific situation. On our website, we indicated per cabinet what the specific characteristics of that cabinet are.

The difference between various blast cabinet brands Normfinish produces two brands of blast cabinets : Normfinish and the Mistral-series. Pressure blast cabinets Schematic of Pressure blast process Pressure blast cabinets are selected when the blasting process has to be completed in a shorter time. Injector blast cabinets Schematic of injector blast process Injector blast cabi n ets , also known as suction blast cabinets, are chosen if a less intensive blasting operation is sufficient to treat the object.

An easy way to wrap your head around this that works regardless of the part's shape is to picture it inside a box, and then flip it visually in your mind to determine the required blast cabinet size.

Look to the Shop Standard line for larger cabinets with smaller non-Production dust collectors when you require a large cabinet for non-Production blasting. What makes a Production cabinet suitable for Production work is the dust collector. Negative pressure dust collectors are the cleanest and most efficient to operate. In a negative pressure dust collector the Exhaust Blower is located on the clean side of the dust collector filters.

This creates longer blower life because the air drawn through the blower has already been cleaned. Media Blast's negative pressure dust collectors offer larger filter areas for maximum use between filter cleanings.

As dust and spent abrasive collect on the dust collector filter surface, blower performance is decreased. Therefore, the more filter surface you have, the longer a machine will operate before filter cleaning is required. Media Blast's Production machines are easy to service and offer self-cleaning dust collector filter assemblies.

If dust collector cleaning is easy, the operator can clean the collector faster and more frequently. If cleaning is difficult and time consuming, the operator often neglects this important duty. Media Blast's hopper bottom dust collectors are the easiest to drain and they allow for environmentally safe dust removal. Keep in mind that Production is a word which describes many things, but applied to sandblasting it refers to operating a machine daily for periods of 1 hour or more.

Even small 5 HP abrasive guns will discharge almost 3, pounds of abrasive in 8 hours! If your compressed air is limited to 20 CFM, Light Duty machines are great tools, but are not well-suited for applications requiring daily use. Production machines can also operate with smaller abrasive guns and this creates an operation that requires very little maintenance and reduces labor time. All sandblast machines, whether siphon or Direct Pressure, use compressed air to force the abrasive against the part being cleaned.

Siphon machines use suction to pull the abrasive into the blast gun while pressure machines use a pressurized pot to pneumatically push the abrasive to the blast nozzle. Siphon machines use an abrasive gun with two hoses, one for compressed air and one for abrasive delivery to the gun. Pressure machines use a single hose with a mixture of compressed air and abrasive. Siphon machines are the most common type of abrasive machinery.

A siphon machine can run for very long periods of time while Direct Pressure machines must be stopped about every five to seven minutes to allow the Pressure Pot to recharge.
