CHAPTER 20: SIZE REDUCTION EQUIPMENT FOR SIZE

• Much more versatile than smooth roll crusher • Best example Break and reduction rolls of wheat milling • Disintegrators are toothed roll crushers in which the corrugated rolls are rotating at different speeds • Size reduction is by compression, impact and shear and not by compression alone, as in the case of smooth roll crushers

Size Reduction Equipment Welcome to BIT Mesra

•Toothed roll crushers are much more versatile then smooth roll crusher, within the limitation that they cannot handle very hard solids. •Operated by compression, impact and shear. •The particle size feed to these machines may be given as great as 500 mm and the capacity is 500tons/hr. Crushers : Toothed Roll Crushers
