Aerated Bottoms
Aerated bottoms are used to promote consistent product withdrawal from large-diameter flat- or conical-bottom storage silos. It does this by passing low-pressure air through a porous membrane media and into the bed of the material being handled. The low-pressure air is then passed up through the material in the silo, giving it a highly fluid property. You can handle a large variety of materials with aeration conveyors. The criteria are particle size, moisture content and temperature. Generally a product should have a particle distribution of 100% through a 20 mesh screen. Moisture content should be below 1% and temperature can not exceed 1200 degrees Fahrenheit [649˚ C]. The absence of moving parts and low power requirements make air gravity conveying the most economical means to convey fine materials over short or long distances.
