Micro to Mid-Rate Disc Feeding — Precise, Fast, Clean
Disc feeders meter powders, pellets, flakes, and granules with exceptional repeatability from gram-per-hour micro-dosing to hundreds of pounds per hour. Quick-exchange designs and optional gravimetric control make Orbetron a go-to for labs, extrusion, molding, and batching.
Overview
Each Orbetron disc feeder uses a precision-machined rotating disc with metering cavities to deliver a defined volume per revolution. Configure as volumetric or upgrade to loss‑in‑weight gravimetric with Orbetron controls. Quick-exchange housings and 3D-printed custom discs simplify changeovers and scale‑ups.
50 Series Micro Disc Feeder
Ultra‑compact micro dosing
50 mm (2”) disc. Feeds approximately 1 g/hr to 1 lb/hr depending on material properties. Ideal when space is tight and rates are very low.
- Volumetric or loss‑in‑weight gravimetric
- Quick‑exchange, easy‑clean housing
- Multiple disc patterns (6/12/24/48 cavities)
100 Series Disc Feeder
Most versatile, lab to production
100 mm (4”) disc. Typical range 0.01 lb/hr to 200 lb/hr with proper disc selection and flow aids. Popular across pharma, food, plastics, and chemicals.
- Multiple materials: aluminum, 304/316 SS options
- Optional agitation and EZI‑Dock™ refill interface
- Quick‑exchange section via tri‑clamp
150 Series Disc Feeder
Bridges micro and higher‑rate applications
150 mm (6”) disc. Typical range 0.6 lb/hr to 500 lb/hr depending on bulk density and particle size. Compact footprint with big performance.
- 48/24/12‑cavity discs; custom patterns available
- Volumetric or loss‑in‑weight
- Agitation/mechanical release for poor‑flow powders
200 Series Disc Feeder
Largest micro‑disc platform
200 mm (8”) disc. Typical range 0.1 lb/hr to 800 lb/hr with the right disc and hopper configuration. For high‑demand micro to mid‑rate processes.
- Quick‑exchange design; stepper‑driven precision
- Batch or continuous; integrate loaders and level
- Multiple mounting and hopper choices
OBLIW‑SM Batch Blenders
Disc‑based precision blending
OBLIW‑SM mini and micro blenders use disc feeders to dose each component into a weigh hopper for exceptional accuracy and clean changeovers. Retrofit kits (OBB‑R) can upgrade many existing blenders to disc‑based dosing.
- Compact, dust‑tight design; high‑temp capable
- Feeds powders, pellets, or granulates with low air use
- Expand from 4 to 6+ components with electrical upgrade
OSDS Feeder Stations
Modular stations for labs and production
OSDS modules combine disc feeders with stands, hoppers, and controls into a clean, mobile package. Ideal for trials, color/additive feeding, and small production lines.
- Volumetric or gravimetric; recipe‑driven control
- Tool‑less cleanout and quick screw/disc swaps
- Easy integration with extruders, mixers, or packaging
Compare Disc Feeder Models
Select a disc diameter and cavity pattern to match your rate and material. Upgrade to loss‑in‑weight for tighter tolerances or batching.
| Model | Disc Diameter | Typical Rate Range* | Best For | Notes |
|---|---|---|---|---|
| 50 Series | 50 mm (2") | ~1 g/hr – 1 lb/hr | Micro‑additives, labs, R&D | Tiny footprint; multiple disc patterns |
| 100 Series | 100 mm (4") | 0.01 – 200 lb/hr | Versatile go‑to across industries | Agitation & EZI‑Dock™ options |
| 150 Series | 150 mm (6") | 0.6 – 500 lb/hr | Mid‑range production | Great with poor‑flow powders using aids |
| 200 Series | 200 mm (8") | 0.1 – 800 lb/hr | Higher‑rate micro to mid | Quick‑exchange, stepper precision |
*Actual rate depends on bulk density, particle size, flow‑ability, and disc selection.
