Calculation method for determination of the recoverable volume flow of highly inclined screw conveyors

The dimensioning and sizing of heavy inclined screw conveyors for bulk materials is today often based on the experience of the manufacturers. To assure an efficient sizing based on trusted calculation methods the Institute of Materials Handling Material Flow Logistics (fml) is working on a research project, funded by the Deutsche Forschungsgemeinschaft (DFG), which is aimed at analyzing inclined screw conveyors. Determining element of the project is the forecast of the conveying character inside the Screw conveyor and therewith the designation of the achievable volume flows as a function of the geometry and operating parameters. In order to achieve this data for the achievable volume flow for numerousness different parameter combinations are gained and statistically evaluated. By the use of regression analyses a computable interrelationship is finally developed.
