Powder screw conveyor for abrasive material – 34778

Powder screw conveyor for abrasive material delivered for the process industry.

How can you improve the lifetime of the screw conveyor with abrasive material?

1. Use an abrasive steel quality for the screw flights and the casing. In this case duplex steel has been used for the housing to increase the life time
2. Ensure a low filling degree of the screw conveyor
3. Reduce the speed of the screw rotor

Using these guidelines this will increase the lifetime of the powder screw conveyor significantly. The guidelines will in general require a screw conveyor with a larger diameter. Do not consider this as a problem or issue. The increased lifetime will optimize your total cost of ownership.

How can BEMA assist you in the design process of a screw conveyor for abrasive material?

1. Check the capacity calculation and ensure a low filling degree
2. Select a drive solution with a reduced speed compared to a “normal” screw conveyor solution
3. Assist to select abrasive resistant steel types
4. Design the screw conveyor with steel elements, which easy can be changed over years of operation as wear parts
