Streamline predictions for pneumatic conveyors

Article Abstract:

A two-step procedure to predict key parameters for pneumatic conveying systems is presented based on data that was run on 18 dilute- and dense- phase systems in an existing, clay-like material processing facility. This proposed approach determines pressure drop and transfer capacities for new and existing configurations. It is a useful tool in optimizing or modifying pneumatic systems. A correlation was developed for clay but may be applied to any material being conveyed.

Electric-to-pneumatic converter

Article Abstract:

ControlAir has introduced the Type 1200 Eltop electric-to-pneumatic converter that can be utilized in hostile environments. The converter, which uses an electronically operated reversible 24-VDC monitor, is explosionproof because of its NEMA 7X enclosure and stainless steel regulator. The converter, which also has limit switches to prevent motor burnout, can be used for valve actuation applications on gas transmission and distribution pipelines and commercial utilities.
