Under the blast media hopper, placed under the base of the cabinet floor or under the cyclone unit, you will find the blast media pick up device, referred to in our introduction Part 1. There are several designs on the market each purporting their advantages, however, in principle they almost always work the same, some designs better than others. It is important to understand how this simple but effective pick up method works as this is critical to the process.
To draw both blast media and air in through this pick up device, it requires to be set up by adjusting the air to media ratio. Once fixed, this is set and need not be changed until another blast media or size is required.
