Abstract

In coke shop 1 at Ural Steel, double ten-roller screens are employed for primary sorting of coke to isolate the >25 mm fraction, which is sent by conveyers to large-coke hoppers for subsequent loading on railroad cars. These screens are of complex design and difficult to maintain and repair, while the drives are of low efficiency. In screen operation, unplanned downtime is encountered. To improve their reliability, the existing drives of the sorting stands and the mechanisms for moving the screen are replaced by simpler and more reliable designs with a gear motor. Updating the screens simplifies their design and improves their reliability; reduces maintenance and repair costs and the frequency of unplanned downtime; and lowers production costs.
