(BPS), are designed to smoothly convey products. Flow of material is adjustable, and flow rate can be variable or fixed. Available in electric or air-operated models, BPS heavy-duty vibratory feeders are designed with above-, below- or side- mounted drives and can be arranged for base mounting or overhead suspension. Feeders come in custom vibrating trough lengths; special trough designs available. Several basic models are available including air-operated light duty, air-operated heavy duty, twin-motor vibrating pan and grizzly feeders, electromagnetic, twin motor and special application feeders. Options include the BPS Inertial Isolation System™ that is designed to eliminate the transfer of vibra- tory energy to support structures and buildings. BPS manufactures a complete line of custom-engineered, bulk-processing equipment and systems. With more than 100 years' combined experience, the company serves a wide variety of dry processing industries from chemicals and food to aggregates and recycling. Best Process Solutions Inc., Aerodyne Environmental Pitches Dust Efficiency Clinic Aerodyne Environmental, a manufac- turer of industrial dust collectors and material handling valves, now offers dust collection system operators a range of system evaluation services through its Dust Efficiency Clinic. These services can be tailored to boost the efficiency of an operation's dust collection system, decrease maintenance costs, prolong equipment life or improve compliance. "There's much more to dust collection than installing equipment like cyclones and baghouses," said Dan Navicky, an applications engineer at Aerodyne. "Every facility represents a unique set of challenges because each has a dif- ferent set of applications, operating conditions, and dust types. Our system evaluations offer facilities a cost-effec- tive way to gain an understanding of their system's operation and get recom- mendations on increasing its efficiency." Navicky described the dust collection problems that have led some system operators to turn to Aerodyne for help recently. He noted, "We consulted with one company that had installed a hood to prevent fugitive dust from escaping, but the hood was located too close to their process and the airflow was too high, so it was actually picking up prod- uct and sending it to waste. We also worked with another company that had piles of dust around their facility in a combustible process. This could have led to a fine for housekeeping if there had been an inspection. Another cus- tomer's baghouse was clogging up due to moisture that was coming in through the cleaning system. We advised them to install a cyclone prefilter to minimize the amount of dust reaching the bag- house filters, which extended bag life while increasing dust removal." Aerodyne charges system operators a consulting fee of approximately $1,000 for each day required to perform the evaluation, plus expenses. System eval- uations may include: •  A safety assessment: An Aerodyne dust collection specialist will review and inspect the facility's equipment, installation, controls, and protective devices. This assessment evaluates the facility's hoods, ductwork, explo- sion vents, housekeeping, and other related areas. The assessment report will include suggestions for areas of improvement so that the dust col- lection process will comply with the latest NFPA standards. This safety assessment is recommended as a preliminary step before conducting a Dust Hazard Analysis. •  A collection assessment: This assess- ment starts with gathering physical data on system airflow, temperature, static pressure, etc., in addition to a review of the various parts of the system, including the dust collector, fans, dampers, ductwork, hoods, etc. It includes recommendations for changes and operating suggestions to improve system performance and removal efficiency and decrease maintenance, filter replacement fre- quency, etc. Aerodyne Environmental, BPS Vibratory Feeders Designed For Tough Jobs
