Calcium carbonate (Durcal 65) was used as the feed powder and aqueous polyethylene glycol (PEG 4000) as the binder. The dried granules were analysed for their strength, density, size distribution, and wall make-up. Granules were produced in granulators with four scales, 1, 5, 50, and 250 L under three scale-up rules of constant tip speed, constant shear stress, and constant Froude number. The results show that regardless of equipment scale, increasing the impeller speed has a great effect on crushing strength and stress. The underlying cause is an increase in granule density due to more consolidation at higher impeller speeds. Wall make-up is significantly reduced to less than 5 as the scale is increased from 1 to 250 L. The results of this study corroborate our previous findings that the constant tip speed rule is the best criterion for scale-up of high shear granulators. © 2013 Chinese Society of Particuology and Institute of Process Engineering, Chinese Academy of Sciences. date: 2013 official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84890116451&doi=10.1016%2fj.partic.2013.02.004&partnerID=40&md5=8cf8768ba640ff1a5bf8f3937864a166 id_number: 10.1016/j.partic.2013.02.004 full_text_status: none publication: Particuology volume: 11 number: 6 pagerange: 627-635 refereed: TRUE issn: 16742001 citation: Rahmanian, N. and Ganimi, T.E. and Ghadiri, M.
