Front-End Loading (FEL) III


Completed a FEL III for a company producing the filling sand/compound for brick pavers. This included the full design and integration of equipment stands and transitions.

Project Highlights:

  • This system will take unprocessed sand, go through a dryer to reach the proper moisture level, and sift to remove the unrefined pebbles. The sand is then conveyed to a silo for storage.
  • Weigh batchers are used to measure the accurate amount discharging from the silo, with a Chainvey conveying the material into the building. Additives are mixed in to make the final compound.
  • Central dust collection is integrated throughout.
  • Project manager provided full support for bid packages and permit processing.
  • Spec Engineering’s Controls department automated the system for high efficiency
