A recent production run of custom-made screw conveyor blades, made from wear-resistant steel (NM400) and designed by CAFU for a customer in the cement industry, has been completed and packaged for shipment.
A screw conveyor blade is an essential component of a screw conveyor system.
It is typically a helical-shaped element that rotates within a tubular or trough-shaped housing to move materials. The blade design is crucial for efficient conveying.
Some key features and considerations of screw conveyor blades include:
Material: Made of various materials such as steel, stainless steel, or other alloys, depending on the application and the properties of the material being conveyed.
Pitch: The distance between successive turns of the helix, which affects the rate of material movement.
Diameter: Affects the capacity and speed of the conveyor.
Shape and thickness: These can be customized to handle different types of materials and operating conditions.
Wear resistance: Important for applications where abrasive materials are being conveyed to ensure a long service life.
Efficiency: A well-designed blade ensures smooth and consistent material flow.
For example, when conveying high temperature materials, it is recommended that high temperature alloy material be used for the auger blades to extend screw blades life and reduce downtime.
