MANTIS Conveyor Products

Aggregate Conveyor Systems

MANTIS helps you move crushed stone with confidence.


Conveyors for aggregates, agriculture, frac sand, mining, & more need to be up and running. MANTIS engineered aggregate conveyor parts deliver more uptime with less maintenance, for lower total cost of ownership.


MANTIS Conveyor Products® are backed by more than 60 years of expertise in the design, engineering, and manufacturing of mechanical motion parts and assemblies, from concept through production.

USA Made, Global Reach

MANTIS Conveyor Products are created and tested in our US-based 140,000 square-foot facility, with on-hand inventory and same day shipping capacity.

The Future of Material Handling

Each year, the United States aggregate industry mines and sells over 2 billion metric tons of crushed rock, sand, and gravel, employing over 100,000 people. Any aggregate conveyor system downtime means lost productivity, lost profits, and lost opportunity. MANTIS Conveyor Products® are engineered to keep your conveyors and your business up and running.

CEMA Idlers

  • Patented design
  • Internal edge weld – no contact with conveyor belt
  • Four layers of protection from contaminants that cause other idlers to break down:
    1. External Nylon Labyrinth Seal
    2. Secondary Internal Labyrinth Seal
    3. Chamber Lock Technology
    4. Proprietary Defender Bearings

Troughing Assemblies

  • Lighter weight and high-engineered performance
  • Streamlined 3-piece design with fewer welds; provides far greater durability
  • Engineered for better belt alignment, less spillover
  • Center-section Spillover Passages stamped out of frame to create risers without any weak-point welds
  • Spillover Passages allow debris to fall through frame; won’t build up on base
