Conveyors can be synchronous or asynchronous. A conveyor is synchronous if all the material on the conveyor moves at the same time and at the same speed, it is an asynchronous conveyor otherwise. Examples of synchronous conveyors are belt and roller conveyors; an example of an asynchronous conveyor is an automated electrified monorail or AEM.

Screw Conveyors and High-Temperature Applications
For a high-temperature application, you need to ensure that your screw conveyor's structural components are designed based on the steel's yield strength at your worstcase operating temperature. For example, Type 304 stainless steel has a yield strength of about 30,000 psi at 70°F but only about 15,000 psi at 1,000°F.
