Building America starts with us

This is a responsibility we take seriously. We are focused on engineering and manufacturing the highest performance conveyor components possible with the fastest lead times in the industry.

Our catalog of innovative and problem-solving components includes products such as:

  • The new Interceptor™ Super Duty Self Cleaning Magnetic Separator
  • The new Premier™ Duty Drum Pulley
  • The proven and patented Vortex® Spiral Clean Pulley
  • Titan™ Series Impact Beds
  • Maintenance-free CEMA C & D Class Idlers 

The NEW Interceptor™ Self Cleaning Magnetic Separator is the most powerful permanent magnetic separator available that is designed specifically for portable plants. Design features include a high power permanent magnet, a compact and lightweight design, a lagged drive pulley, a low-profile drive (electric or hydraulic), and Slide Tube® Take-Ups. Interceptors™ are shipped factory-test-run and ready for installation.

The NEW Premier™ Duty Drum Pulley is the most dependable and durable pulley on the market today. Premier™ Duty Drums feature the specially engineered rim thicknesses, and integral end discs. The end result is, as always with innovative Douglas® components, a significantly longer service life. 

The patented and proven Vortex® Spiral Clean Pulley is the most unique and innovative self-cleaning pulley concept on the market today. The proprietary design of the flights, and end plows efficiently moves tramp material to the edges of the pulley, and away from the belt, reduces vibration by maintaining continuous belt contact, and virtually eliminates the noise commonly associated with self-cleaning pulleys. The unique and durable design is finished off with AR400 center and edge support sections that significantly increase the overall service life of the Vortex®.

Titan™ Series Impact Beds are the most rugged, and reliable impact beds available today. With unique features such as adjustable angles, and sectional designs, these impact beds are easy to use, and reduce maintenance costs by adding strength at critical areas of the conveyor. 

CEMA Class Idlers feature a patented 3 lip polymer contact seal that keeps contaminants out of the bearing, and keeps the roll turning. Heavy gauge frames, and CNC machine idler shafts add to the overall value, and durability of the design. 

The Guardian® is the gold standard of return roll guards. The patented design provides complete pinch point protection. The single piece lightweight UHMW cage is durable, easy to install, and economical to ship. The Guardian® complies with MSHA Title 30 CFR.

We also manufacture a complete line of screw take-ups for belt conveyor systems: the Slide Tube®, Heavy Duty Top Mount, Light Duty Top Mount, Top Angle, Center Pull, and Wide Slot.
