Reliable, 24/7 Drag Chain Conveyors Built for the Aggressive Demands of Alternative Fuel Applications and Power Generation Material Handling

CDM Heavy-Duty Drag Chain Conveyor
Power generation has proved to be a challenging operating environment in recent years. Regulation, emission controls, recent memory nuclear fears, and the challenge of storage with renewable power are all providing for increased variable operating conditions and rising costs. For these reasons, your business must operate as efficiently as possible. Reliable material handling equipment is one aspect of that efficiency.

  • Fly Ash
  • Bottom Ash



Precision-Engineered Drag Chain Conveyors for Handling and Cooling Ash

CDM Cooling Ash Handling Conveyor System
CDM drag chain conveyors can be designed to cool ash as it comes off the bottom of the boiler in a large coal-fired utility. The unique design eliminates water-cooled screw conveyors that are maintenance-heavy and cause safety-related issues for workers. The inlets of the conveyors are designed to provide an air lock on the boiler by choking the inlet feed and maintaining a seal of material.


Custom-Built Conveying Systems for Fly Ash Handling

CDM High Temperature En-Masse Conveyor

Mechanical conveying systems for handling fly ash are often the most economical to purchase and the most energy efficient vs. expensive compressed air dense- or dilute-phase pneumatic systems. Choosing a CDM Drag Chain Conveyor to efficiently move high-volume fly ash in a sealed system helps support EPA Regulation Compliance. We have more than 40 years of experience working with power producers or E&C firms to design a complete material handling system for your specific ash-handling application.

  • Abrasion-resistant drag chains and components
  • Shear pin roller chain drive sprockets for overload protection
  • Quick opening, tight shut-off, stainless steel access doors
  • Air- and dust-tight operation

These are general equipment selection guidelines only. Contact a CDM expert to discuss the best options for your specific application.
