22 May 2020 Tablets & Capsules particle size: reduction, separation, & analysis Air classifier for fine powder separation Air classifier works as a stand-alone unit or in combination with one of the compa- ny's complementary mills as a milling and classification system. Classifier is avail- able in seven different sizes to achieve a wide particle size cut point range from 4 to 160 microns. Cut point adjustment is automated through a PLC control. Welded structure is pressure shock resistant up to 10 bars and is compliant with ATEX and NFPA containment requirements for explosion mitigation. Bauermeister USA, Memphis, TN 901 363 0921 www.bauermeisterusa.com Conical mill Uni-Mill series conical mills achieve a narrow particle size distribution, generate very little heat and dust, and produce scalable results for dry and wet milling. Gear- box-driven impeller rotates inside a screen, creating a spacerless design that pro- vides an optimal gap for particle size reduction. Interchangeable tooling and a large range of screens and impellers allow manufacturers to customize the tooling set-up to achieve the exact particle size distribution and throughput desired. Other features include a detachable mill head for autoclave or CIP/WIP, temperature monitoring, pre-breakers, and nitrogen purging. Explosion-proof versions are also available. Mill head can remain freestanding or can be mounted to a mobile frame, swing arm, or height-adjustable hoist. Hanningfield North America, Hillsborough, NC 919 338 2884 www.hanningfield.com Powder flow tester PFT powder flow tester can be used to quickly analyze material flow behavior in processing equipment, evaluate powder discharge from storage containers, check incoming material for quality, and rapidly characterize new formulations for flow- ability, allowing operators to adjust a formulation's composition to match the flow behavior of established products. Unit defines key bulk solids measurements for flow function and index, arching dimension, internal friction angle, rathole diam- eter, hopper half angle, gravity chute angle, wall friction angle, bulk density, and compressibility index and ratio. Options include wall friction lids, a temperature probe, a humidity sensor, and sieve kits. Ametek Brookfield, Middleboro, MA 800 628 8139 www.brookfieldengineering.com A survey of what's available
