Do RollSizer model numbers define every part dimension?

No. The same machine size can have different roll lengths, centre or side crushing geometry, tooth profiles, single/dual drives and project configurations. Quotations require the full DRS model, serial number, general arrangement drawing, toothed roll layout and part position.

How are crushing tooth materials selected?

FLS specifies crushing tool materials by application. Confirm actual material against feed hardness, abrasiveness, impact, stickiness, particle size, tooth profile, holder, used-part material and failure mode.

Q: Are CenterSizer and SideSizer parts interchangeable?

Machine size alone is insufficient. CenterSizer crushes between the rolls; SideSizer crushes between the rolls and side combs. Check structure, machine size, roll length, tooth profile and position, rotation direction, side combs, drive and drawings.

Are CenterSizer and SideSizer parts interchangeable?

Machine size alone is insufficient. Crushing position, side combs, tooth profiles and discharge clearances differ. Check the complete structure, roll length, tooth position, drive, serial number and drawings.

Why is roll length needed even when the machine size is known?

The official table lists several standard roll lengths for a single machine size. Weight, tooth segment count, shaft system and housing change accordingly. Machine size is only the first level of installation identification.
