In the present work, the performance of a case study screw conveyor in Shahrebabak copper complex has been studied. The design of screw based on the standard design codes, especially CEMA code, has been investigated to determine the design problems. The variation graphs of the screw speed, material rate and the upper bin discharge have been recorded to use in evaluations. Data collection revealed that the screw conveying rate of material did not match with the evaluations which given by the standard codes for the conveying capacity of screw. The data were used to derive a correction factor between the operational data and theoretical relations of conveying capacity. By the obtained correction factor, the relation for evaluation of the case screw capacity was derived and by with, the maximum screw capacity was determined. Redesign of screw, according to the material conditions and required capacity (of about 72 t/h) has been performed.
