A s THE MICROSCOPE SHOWS, each grade of Celite* diatomite has its own distinctive particle size dis tribution. Yet no matter where or when purchased, each remains uni form from bag to bag—your assur ance of top production results with minimum down-time. Three examples of flux-calcined Celites are shown here. Hyflo® Super Cel is widely used for filtra tion in many industries. I t has just the right combination of coarse and fine particles t o assure optimum clarity and flow rates. Celite 545, with a higher percentage of coarse particles, is used t o achieve maxi mum clarity and faster flow rates with liquids t h a t have larger sus pended particles.
Super Floss, one of several bag house grades, has fine particle size distribution. A white powder, it is processed within very narrow toler ances (less than 1% retained on 325 mesh). I t is a popular filler in fine products such as silver polishes. Johns-Manville can precisionproduce so many different grades of Celite because it mines the material from the world's largest and purest commercially available deposit.
