Which of the following is not a criteria used to determine the type and material of a chain used for chain conveyors?

The choice indicating requirements for chain material is not a criterion used to determine the type and material of a chain for chain conveyors because the criteria typically focus on operational aspects rather than the material specifications themselves.

When selecting a chain for conveyors, factors such as horsepower and speed are crucial since they influence how much load the chain can handle and at what operational velocity it will efficiently function. Additionally, understanding the chain movement for the application helps in selecting a chain that can properly navigate bending and tension challenges. The movement of the product for the application is key as it determines how the chain must interact with the items being conveyed, ensuring that the design is compatible with the operational flow.

These operational aspects guide engineers and maintenance professionals in selecting the most suitable type of chain for the specific needs of the application, maximizing efficiency and longevity, while material requirements are usually predetermined based on these operational metrics and are often secondary to the immediate functional criteria.
