Meet SCC

Screw Conveyor Corporation® is a family owned manufacturing business that has served the bulk material handling industry since 1932. Clarence F. Abraham, one of the original founders, worked tirelessly to create a legacy that is now under the leadership of third generation brothers, Garry M. Abraham and Curtis F. Abraham along with fourth generation, Craig C. Abraham.

The original location of Hammond, Indiana still serves as Corporate Headquarters and along with Winona, Mississippi and Visalia, California makes up the United States facilities of Screw Conveyor Corporation®. Guadalajara Mexico is home to our sister company, Screw Conveyor de Mexico®. The three U.S. locations serve the North American markets while Screw Conveyor de Mexico® serves the markets throughout Central and South America.

Customer service is handled by both the Hammond Indiana and Visalia California locations with all three U.S. locations having manufacturing capabilities. These geographically diverse locations allow Screw Conveyor Corporation® to meet the varied needs of our customers. We engineer and manufacture a complete line of conveyance systems including:

  • Screw conveyor components from 4” to 30” diameter.
  • Super Flo® round bottom and Enduro Flo® flat bottom drag conveyors.
  • Bucket elevators: Single Trunk, Double Trunk High Capacity, Super Capacity and Mill Duty.
