Chain Analysis Reveals Why Formula Matters

The data presented below are the results of an independent lab chemical analysis. The analysis was performed using 10 different industry available drag chains currently selling in the industrial market. Of the 10, we show 6 here because 4 were not even alloy steel making them an unequal comparison to the CDM Systems Chain Formula. The 6 manufacturer’s chain assemblies that use an alloy steel are shown below.

The Chain Formulation Means the Difference Between Potential Catastrophic Failure and Operating Long-Term at Full Capacity

The most important feature of any drag chain formula is the effective case hardness depth. Once this case is worn through, elongation will accelerate and become a significant factor in maintenance. However, case depth is not unlimited and not the only factor in building a strong chain. The right formula or case hardness and ductility are critical. Too hard, as with a depth noted above of .055 and the ductility and impact resistance will be compromised and cause failures.

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.
