QUADRO ® COMIL ® How Do All These Affect The Milling Process Cont’d Capacity: The capacity would be highest for the 1612 because more particles can be "grabbed" and pushed out through the screen. The 1601 would be ranked second, the 1607 third and the 1609 fourth. Fine Generation: The 1609 will cause the particles to be retained in the screen longer, hence a higher residence time. When that happens, there will be more inter-particle attrition creating more fines. This impeller is selected when the user requires fine particles. The other impellers create less fines, as per the above noted sequence. Screen Pressure: Highest on the 1612 impeller and lowest on the 1609 impeller. Amperage Draw: Highest on the 1612 and lowest on the 1609 impeller. S CREEN S ELECTION Quadro has designed and manufactured hundreds of different types of screens but this Bulletin illustrates the few basic types. “R” Round Holed Screens: Used primarily for dry sizing or powder into liquid dispersion. Applications incude dry granulation sizing in tablet manufacturing, bakery mix fat dispersion, deagglomeration of soil, sizing and bulk density tuning of spray dried powders. Sizes range from 0.006” (0.15mm) - 0.250” (6.35mm) hole diameters. “Q” Square Holed Screens: Used for wet (moist) product sizing and when larger particle sizes are required. Applications include wet granulation sizing/dispersion in tablet manufacturing, sizing moist chicken or seafood coating for reclaim, de-wrapping candy, cheese chunks and sizing centrifuge solids. Sizes range from 0.156”H X 0.156”L (3.96mmH X 3.96mmL) to 1.00”H X 1.00”L (25.4mmH X 25.4mmL) hole dimensions; where “H” and “L” are the Height and Length, respectively. “S” Slotted Holed Screens: Used for breaking capsules before the “G” screen was introduced. Applications include wet granulation sizing/dispersion in tablet manufacturing, separating dried fruits such as raisins, cranberries, apricots, apples and pineapples (note, please consult Quadro for a specially designed “S” screen for these applications), breaking glass bottles/syringes for drug reclaim, sizing wet detergent lumps from cyclone wall build-up. Sizes range from 0.156”H X 0.380”L (3.96mmH X 9.65mmL) to 1.00”H X 2.18”L (25.4mmH X 55.37mmL) hole dimensions; where “H” and “L” are Height and Length, respectively.
