There are two types of screw conveyor blades: shafted blades and shaftless blades. The selection of screw conveyor blades is mainly based on the nature of the conveyed material.
Which materials are suitable for shafted blades?
Shafted blades are suitable for conveying materials: powder, small particle materials (such as flour, soybeans, concrete, etc.), if conveying viscous materials such as sludge, it will stick to the inner tube shaft and blades, and it is easy to convey bulk materials Stuck.
Which materials are suitable for shaftless blades?
Materials suitable for conveying by shaftless blades: there are certain viscous, entangled materials and bulk materials (such as sludge, domestic waste, grid slag, etc.), it is precisely because the design of the shaftless screw conveyor without a central shaft is suitable for These materials have great advantages.
Material distinction: manganese steel, carbon steel, stainless steel.
Manganese steel material:the strength of the screw conveyor blade made of manganese steel will be higher, and its anti-wear performance will be better, which is suitable for conveying materials with strong cutting properties. It is suitable for highly abrasive materials.
Carbon steel material:screw conveyor blades made of carbon steel are widely used to convey general materials.
Stainless steel material:stainless steel screw conveyor blades can transport acid, alkaline and high temperature materials, they are also used in industries with high requirements for hygienic environment.
