Flat-Tray Feeders: Compact for High Precision
ZD 5 FB - Ultra-Low Rate Feeder
Probably the smallest flat-bottom twin-screw lab feeder in the world, it excels at micro compounding by dosing poorly flowing and free-flowing powders that clump or cake on hopper walls or readily bridge.
Technical data
Throughput 0.003- 1.45 l/h Weight ≈ 6 kg with potentiometer, ≈ 8 kg with logo or S7-1500
Ø Metering tools 5 mm Speed 1-500 min-1
Motor Stepper motor Hopper volume 0.1 l (standard)
ZD 5 FB i6000
The ZD 5 FB i6000 functions as a gravimetric feeder, using built-in WL260 SP-S AE load cells and WP 231 electronics from Siemens for precise loss-in-weight micro feeding. This innovative all-in-one solution is easy to position thanks to optimized cable routing and low weight. A low drop height reduces sensitivity to drafts or vibrations, increasing process safety, while the lighter frame improves load-cell resolution—delivering micro feeding accuracy to ±0.015 %. Optionally, the system can be built to GMP, FDA, and/or ATEX guidelines.
Advantages:
• Flexibility
• Multifunctional
• Space-saving
• Efficient and economical
• Easy
• Optimized cable routing

ZD 9 FB
The ZD 9 FB twin-screw feeder with flat bottom provides precise volumetric or gravimetric feeding for poorly flowing and free-flowing powders that clump, cake, or bridge. Ideal for R&D and production alike, it covers rates from micro-scale tests of 0.003 l/h up to 1.45 l/h. A bottom scraper discharges bulk material gently and completely, ensuring consistent throughput and clean hopper walls.
