Abrasive Blasting 101
Did you know some media blasters, also called blasting cabinets, can be used to blast large parts instead of blasting rooms?
Blast rooms are used to process extra-large parts. Some things, like automobiles, may require an entire blast room. But there are many applications that don’t require that allocation of resources. This is where media blasters come in handy.
Disadvantages of Blast rooms
Every company with a blast room also has media blasters. This is because Industrial Cabinets all recycle and reload the pressure pot almost automatically. It’s prohibitively expensive to run a blasting room for every single part that needs to be processed. Anything you can load inside the cabinet or onto a mobile work cart complete with turntable allows the operator to reach the part for blast.
Many double-wide and quad media blasters exist. These cabinets are up to 10’ wide and offer both siphon and direct pressure abrasive delivery systems with automatic abrasive recycle and pressure pot reloading. Direct Pressure cabinets allow a longer reach for the operator standing on the outside of the cabinet, so pressure delivery is the most common delivery method in cabinets.
When you’re working with large parts the design of the media blaster is critical to successful blasting.
Our media blaster design comes with the following features that allow for efficient operation:
It can be slower to process a part with a double wide and quad using 4 hoppers compared to processing a part in a blasting room. But it’s likely much time is saved with the cabinet thanks to automatic recycle and abrasive pot reloading. It takes more time to manipulate the part inside the cabinet than it does to walk around a part inside a blast room, but the operator does it all in the clothes they came to work in. But media blasters can more than make up for this lost time in the revenue saved in lower operating costs.
To sum it up, double wide and quad media blasters can be alternatives to a blast room. It’s important to have realistic expectations: no cabinet will have the same production output as a blast room. But not all applications require maximum daily output.
