For this project, EHS fabricated three custom hoppers to feed a vacuum conveyance system. The hoppers were equipped with sight glasses and pneumatic vibrators so that operators could ensure adequate product flow. EHS Ventilation Sleeves were used in the bin openings for containment during the bin charging. The hoppers were filled from drums using a rail-mounted EHS Variable Height Drum Tipper with an integrated work platform. The entire Drum Tipper assembly could be quickly positioned at any of the three hoppers and also easily removed for cleaning.
