Pneumatic Conveying Moves Ahead
Pneumatic conveying has long been a popular choice for moving bulk materials, either from storage facilities to a process unit, or between process units. However, pneumatic conveying technology itself hasn’t been standing still, and this can influence the choice between pneumatic and mechanical systems such as conveyor belts or vibratory systems and then among several types of pneumatic systems: dilute-phase, dense-phase or vacuum. Generally speaking, mechanical systems make sense with short, straight runs within a plant; they require less horsepower and sometimes can be a less expensive capital cost,” says Paul Solt, owner of Pneumatic Conveying Consulting, Allentown, Pa. “But they are usually a higher-maintenance choice, have problems with dust generation or contamination of process material, and are not as flexible in dealing with plant-floor configurations. Given sufficient capital, there is nothing that cannot be pneumatically conveyed,” he says. Greg Steele, executive vice president for Dynamic Air, St. Paul, Minn. , says, “Over the past 15-20 years, we’ve received a tremendous boost from EPA and OSHA. One by one, industries or applications where mechanical conveying has been the traditional choice have gone to pneumatic conveying. A decade or so ago, it was dry laundry detergent, then it was rubber processing and more recently pharmaceuticals. With pneumatic conveying, you reduce emissions and cut down on plant housekeeping requirements. ” Moreover, many new materials are more demanding to handle because of, for instance, reactivity or fire and health hazards; this also tips the scales toward pneumatic systems.Because pneumatic systems run cleaner than mechanical ones and are less susceptible to product contamination, recycling materials is easier. A pneumatic system’s generally smaller product holdup also is an advantage for recycling.
