• Comparison of breakage behavior between the sieving ...

    ABSTRACT Comparison of breakage behavior of coals is conducted between the industrial sieving crusher (SC) and ordinary teeth roll crushers in different breakage flow sheets. Two types of coals, about 10 tons, are used for each comparison, and consumed energy and size distribution of products are analyzed. Due to differences in roll rotation rate and teeth distribution …
