A company that produces additives for livestock feed are looking to produce a key ingredient in-house that they previously bought from suppliers. In order to do so they need to use a spray dryer, which will exhaust 26,000 ACFM. The company needed a way to remove the dust, which are about 16 microns and larger, from and cool the exhaust and turned to Aerodyne for a solution.
After looking into the company’s dust collection and cooling needs, Dan suggested that the company use a SplitStream dust collector for removing dust from and cooling the exhaust. The SplitStream would use the 17,500 ACFM of ambient air in the secondary air stream to cool the airstream while removing 99% of dust 7 microns and larger. The secondary air design of the SplitStream will minimize the dust buildup and cool airflow while minimizing the stickiness that comes with the mixture of dust and most air, making it a perfect fit for the company’s needs.
The Aerodyne SplitStream dust collector achieves high-efficiency by forcing dirty gases into a powerful centrifugal motion. The centrifugal action throws dust particulate out of the gas stream. A secondary air stream carries the dust particulate to the hopper, keeping dust away from the collector walls and reducing sticking and abrasion. As a result, the SplitStream virtually eliminates maintenance problems common to other types of cyclones. The prevention of particulate contact with external walls is a major factor in the unit’s ability to achieve high efficiency ratings. Since the SpiltStream does not use bags or filter cartridges, the collected product is easily returned to the process for reuse or sent out for disposal.
