The MIDWEST Internally Vented Spout Positioner with MV22, MV30 or MV36 Series Internally Vented Loading Spout connected to the lower flange of the positioner or with a Vaculoader® or Compaculoader™ located on the top of the positioner, is designed to load vehicles in up to half the normal loading time and dust free if applied, installed and operated properly. This system is designed to load up to *1400 TPH of 60 PCF dry free flowing moderately aerated fines or the equivalent capacity of granular or lumpy products. Consult factory for throughput capacities, velocities and hopper design to accommodate required loading rate. Because of its internally vented feature the complete stack up of modules or "system" is placed under a negative pressure or vacuum which when maintained, will not allow dust to escape to the atmosphere. Using this MIDWEST system, the operator can horizontally position the MSPV Series positioner and loading spout back and forth across a truck or railcar or parallel to the vehicle, to reach side hatches or to fill both sides of an open vehicle. When installed parallel to the flow of traffic the loading operator can position the Retractable Bulk Loading Spout discharge over a truck or railcar hatch without having to move the vehicle. With several sizes of horizontal positioner travels available it is also possible to reach more than one hatch without moving the vehicle.
