Truck Unloading

Raw materials are often delivered in bulk quantities to facilities exterior storage bins or silos via bulk pneumatic truck.  Bulk pneumatic trucks can carry up to 40,000 lbs. of dry free flowing material, and feature an onboard positive pressure pneumatic blower system for discharging material from the truck into the exterior bin or silo.  The pneumatic blower system conveys material at a high velocity from the truck through a 4” pipeline that is manually connected to a pipeline feeding the top of a storage bin or silo.  Because of the high material velocity in a truck unload system, the 4” pipeline feeding the bin or silo can wear at a rapid rate.  Pipeline components designed to withstand the high material velocities of a truck unload system are key to insuring maintenance costs, and downtime are kept low.  Also, an efficient dust collection system is required to properly vent the storage bin or silo the truck unload system is blowing into.

JDB Truck Unload Components

JDB Dense Flow components feature proven designs built to stand up to the high material velocities of a Truck Unload system.  

 

Pocket Elbow

The Dense Flow Pocket Elbow features a short radius cast body from ductile iron, and is used where a turn or bend in a truck unload pipeline is required (pipeline turns are the point where most wear occurs in a truck unload system).  The elbows design incorporates a “pocket “at the material deflection point which is the place most susceptible to material abrasion.  The initial material being conveyed is trapped in the pocket, protecting the elbows deflection point from any remaining material being conveyed.  By protecting the most susceptible area of the elbow the lifespan of a Pocket Elbow is greatly increased, and can last up to 10 times longer than other truck unload pipeline elbows.

Compact Bin Vent

 

An efficient dust collection system is necessary for properly venting the storage bin or silo where a truck unloading system is blowing material into.  The Dense Flow Truck Unload Bin Vent features proven components and design characteristics that maximize overall bin vent performance, and can handle air flow rates up to 828 CFM.  An individual air pulse cleaning system and highly efficient wide pleat filter cartridges promote superior dust release keeping cartridges cleaner, and operating more efficiently. Cleaner more efficient cartridges means they need to be changed less often minimizing downtime, and reducing maintenance costs.

Densealloy Pipe

 

Our Densealloy Pipe goes through an induction heat treating process hardening it to over 600 BHN at the pipe I.D. or inside diameter.  This hardening process translates into Densealloy pipe lasting up to 5 times longer than regular non-hardened pipe.

 

 

Truck Unloading Case Studies

JDB Dense Flow Truck Unloading components have been installed on exterior storage bins / silos of all shapes and sizes, and are effective with virtually any material being delivered via a bulk pneumatic truck.  We offer complete systems on new installations, and can custom fit our components to directly replace existing components.  In our 30+ years’ experience we’ve designed numerous truck unloading systems handling a variety of materials, for many different industries.
