BertSelecting the right volumetric feeder is important when seeking to optimize material dosing in industrial processes. They excel at consistently measuring and delivering predetermined volumes of bulk solids. However, with various options available, selecting the most suitable volumetric feeder for your specific application can be challenging.
This article discusses the key factors to consider when choosing a volumetric feeder and provides insights into when and how to utilize this technology in your application best.
Volumetric Feeder Functionality
Volumetric feeders operate based on a straightforward principle. Material from a hopper feeds into a rotating metering unit designed with screws, vanes, or discs depending on the material’s properties. This metering unit captures a specific volume of material within its cavity with each rotation.
The captured material is then transported to the discharge point and delivered to the downstream process. The rotation speed controls the material feed rate, allowing adjustments to regulate the amount of material delivered per unit time.

Factors Influencing Volumetric Doser Performance
While volumetric feeders offer a reliable and cost-effective solution for material handling, choosing the most appropriate type for your application requires careful consideration of several factors:
Material Properties
Material characteristics like flowability, particle size, and potential for bridging significantly influence the choice of feeder type. For instance, free-flowing pellets and granules are well-suited for screw feeders, while materials with poor flowability might require vane feeders that can handle bridging issues.
Desired Dosing Accuracy
The level of accuracy required for your application is a crucial factor. Volumetric feeders provide consistent volumetric output, but for extremely high-precision dosing, gravimetric feeders that measure by weight might be a better fit.
Required Dosing Rate
Consider the necessary throughput for your process. Volumetric feeders come in various capacities for different needs. Therefore, ensure the chosen feeder can deliver the desired material feed rate.
Operational Environment
The ambient conditions around the feeder can affect material flowability, particularly for materials sensitive to temperature or humidity fluctuations. Environmental controls might be necessary in such cases to ensure consistent dosing performance.
Integration Needs
Evaluate how the volumetric feeder will integrate with your existing process control system. Yushine offers feeders with control units that can interface with various systems for seamless automation.
When to Use Volumetric Feeders Effectively
Volumetric feeders are well-suited for a wide range of applications where consistent volume delivery and cost-effectiveness are priorities. Here are some ideal scenarios for their use:
Plastics Processing
Precise metering of plastic pellets, granules, and flakes for feeding into extruders, injection molding machines, and blow molding machines is a perfect application for volumetric feeders.
Chemical, Pharmaceutical, and Food Production
Volumetric feeders can accurately dose powders and granules for chemical reactions and pharmaceutical manufacturing, mainly when precise volume control is sufficient. Their consistent volumetric output also benefits the controlled feeding of grains, powders, and other dry ingredients for food production processes.
Final Takeaway
By carefully considering the factors mentioned above and understanding ideal application scenarios, you can make an informed decision when selecting a volumetric feeder from Yushine. Their wide range of feeders ensures you can find the perfect fit for your specific needs.
Remember, gravimetric feeders might be a better choice for situations demanding extremely high dosing accuracy. If you’re unsure which feeder type best suits your application, don’t hesitate to consult with Yushine’s material handling specialists for expert guidance.
