McLanahan | Sizers
Sizer tooth wear can be checked by measuring tooth height from the base of the tooth and comparing this with the as supplied tooth height. A tooth profile template can also be used to compare a worn tooth profile with the original tooth profile. Hardface welding can be used to build up or maintain the tooth profile on some types of sizer teeth.
Comparison of breakage behavior between the sieving crusher …
Due to differences in roll rotation rate and teeth distribution on roll, breakage product of SC shows the lower yield of +50 mm particles and −6 mm fines, and the higher content of −50 + 6 mm progenies.

Laboratory-scale validation of a DEM model of a toothed double-roll
But, when rolls' speed exceeds 150 rpm, the crushing performance would not be significantly improved. A reasonable working gap and better nipping behaviour are obtained using the spiral-tooth-roll or the staggered-tooth-roll. The validated DEM model could be applied to gain a fundamental understanding of the crushing mechanisms of TDRC.
