Having a superior chain formulation is only beneficial if the chain design is selected properly and the conveyor engineered around the chain fits the application conveyor and material handling system design, also must account for the total ownership needs of the plant. At CDM we are the industry standard for chain and conveyors because we take the time to ask all pertinent application questions and we make sure we understand the application before making a recommendation.
Our Core Design Principles
The success or failure of drag chain conveyor design depends on the balance of internal components to the application and material handled. That’s why it’s important to understand as much material and environmental data before addressing the components.
When selecting conveyor design elements, the following is critical:
Durability – Wear resistance
Reliability – Components that match the design criteria will provide long service life
Ultimate Strength – This is the measuring stick not the end goal, to be evaluated accurately we also consider;
Impact Resistance – Proven core and case hardness
Fatigue – Wear related to cycling and work loads
Wear Resistance – Product abrasion, speed, articulation vs. high acceptable core and case hardness
Material Handling for a Wide Range of Process Industries
Drag Chain Conveyors are used in a wide range of applications. CDM has been serving processors across the industrial sector for decades. Each conveyor is engineered to meet the specific needs of a given application and results in a conveyor that moves volumes of material reliably and effectively with a low cost of ownership.
