Welcome to Onyx

When seed cotton is transported to the gin plant in sacks, trailers, or trucks, Telescopes, use air suction to unload the seed cotton, convey it into an Unloading Separator, which separates the seed cotton from the conveying air stream.  

 

For gin plants that process seed cotton modules (whether conventional loaf-type or the newer round-type), either a traveling-head or stationary-head Module Feeder is furnished.  The Module Feeder uses high-speed spiked cylinders to pluck the locks of seed cotton from the compacted module, blending the seed cotton across the entire face of the module.    

​

The Automatic Suction Control (or Storage Hopper) is the next machine in the system.  This machine provides for a smooth flow of well-opened seed cotton into the first-stage drying system through the use of two variable-speed Feed Rollers and a Disperser Cylinder feeding a Vacuum Wheel (or rotary air lock).  Lummus offers the Posi-Flo™ Storage Hopper in both 96” and 120” widths.  When unloading via airstream (either through telescopes or from a belt-type seed cotton pick-up on the Module Feeder), the Posi-Flo™ is mounted underneath an Unloading Separator in a complete above-ground machinery stack.  In many Module Feeder applications, though, the Posi-Flo™ is installed underneath the Module Feeder disperser head in a pit.  For low-to-medium capacity gin plants, a single Posi-Flo™ is furnished, and for higher capacity installations, Lummus also manufactures a Double Posi-Flo™ unit (in 120” width) that features two complete sets of Feed Rollers/Disperser Cylinders.
