Drag Chain Conveying Affords Many Advantages Over Other Types of Conveying Technologies

  • Totally Enclosed – Mitigate dusting, keep plant clean and safe, protect product integrity
  • High Temperature – Our conveyor can handle operating temperatures of up to 1,000°F
  • Layout Configuration – From intermediate discharge points, to L & Z-Path configurations, our Drag Chain Conveyor offers cost-effective layout options
  • Speed & Operation – Move large volumes of material at low operating speed
  • Small Footprint – Unlike other conveying types, Drag Chain has efficient use of space to capacity ratio
  • Low Maintenance – Only (2) lubrication points
  • Standardization – CDM conveyors can handle capacities from 1 TPH to +1500 TPH and provide standardization on key components
  • Long Life - Dry Potash conveyors, depending upon application, will provide 4 to 10 years of operating on a single chain

Our Exclusive Chain Formula

As the primary component of a Drag Chain Conveyor, we know how important the Chain is to your process. CDM Systems delivers a complete line of Drop-Forged, case-hardened (60Rc) Conveyor Chains, from 102mm to 260mm pitch, along with multiple connector pin configurations (including custom fabricated) and flight attachments.


CDM Drop-Forged Chain Link
  • Our core hardness for strength and ductility is set at 300-400 BHN — this exclusive formula offers high strength and wear resistance while providing a malleable core that prevents breakage.
  • Machined yokes provide a tight controlled fit between links.
  • Each link is individually pinned for ease of replacement.
  • Chain links are totally carburized to provide an effective case hardness of 550-650 BHN(60Rc) — the outer casing is hard for optimum wear resistance.
  • Chain link bores are machined to provide a full pin/bore bearing area for maximum strength.


Our CrMn alloy allows us to achieve extremely high tensile strengths and hardness. This translates into increased life, wear resistance, durability and economic value.

Application In Review

Potash Producer Realizes Operating Savings through Conveying Equipment Standardization

A global Potash mining and processing company planned for a major expansion at an existing facility in Saskatchewan, Canada along with a new processing plant adjacent to the existing operation. The expansion and new construction would double the capacity of the Potash producer. The expansion was needed to meet the increasing global demand for the Potassium-based lot, used mainly in fertilizers. The CDM objective is to design and build the most suitable equipment for the application and provide the lowest total cost of ownership to clients. The EPC contractor and potash producer realized quantifiable savings though the TCO design approach.
