Feed screws are mechanical components commonly used in various machines to move materials or products through a process. They consist of a helical thread that rotates, pushing the material along a designated path. This design allows for efficient and controlled movement, making feed screws essential in industries like manufacturing and food processing. These screws can be found in equipment such as extruders and conveyors, where they help transport bulk materials. The size and pitch of the screw can vary depending on the application, allowing for customization to meet specific operational needs.
