Screw Feeders vs. Vibratory Feeders
While vibratory feeders are ideal for irregular products or those that might be damaged by mechanical components, screw feeders offer advantages for liquids, viscous slurries, and free-flowing or sticky materials. If your product doesn’t clearly fit into one category, fill out a form or call us—we’ll help you find the right fit.
F.A.Q.: Screw Feeders For Commercial Applications
Here are answers to frequently asked questions about screw feeders for commercial applications. If we don’t answer your questions here, contact us.
What types of materials can screw feeders handle?
Screw feeders are ideal for metering a wide range of bulk materials including powders, granules, chips, flakes, and fibers. They're used commonly for both virgin and recycled bulk solids.
What materials are used in screw feeder construction?
Our screw feeders are built with stainless steel (304 or 316) for durability and compliance with sanitary standards. Other contact surfaces may include HDPE or PTFE.
Do you offer heavy-duty screw feeders for abrasive materials?
Yes, our heavy-duty models are engineered to handle abrasive or dense products and can be customized with hardened components to reduce wear and downtime.
Can screw feeders be used with silos or other storage vessels?
Screw feeders will be fed by some kind of conveyor from storage vessels, like a screw conveyor—which are sometimes confused with screw feeders.
Are these feeders easy to clean and maintain?
Yes. Quick-release clamps, external agitation systems, and modular components are designed to minimize downtime during cleaning or part replacement.
What’s the difference between volumetric and gravimetric screw feeders?
Volumetric screw feeders dispense material at a consistent rate by volume, while gravimetric feeders measure the feed rate by weight. Volumetric is easier to configure and is even more precise when the product is perfectly consistent. This is because load cells (used in gravimetric applications) have their own margin of error and delay in feeding information back to the feeder. However, gravimetric screw feeders will be more accurate for products that are not consistent and have clumps that are heavier than others.
How do I choose the right screw size or screw type for my product?
The correct screw diameter and screw type depend on your material’s flow characteristics and required throughput. Our team can help you determine the best configuration.
What’s the advantage of a twin screw vs. single screw feeder?
Twin screw feeders provide better agitation and consistent feed of difficult materials, including sticky or poor-flowing powders.
How do I get a screw feeder for my operation?
To get started, tell us about your material, desired feed rate, and any special requirements—like sanitation or automation. Our team will help you select the right screw feeding system for your application and provide a custom quote, whether you need a standalone feeder or a fully integrated feeder system.
