Ensuring consistent and efficient material flow starts with a thorough understanding of your material’s properties. At Trantec Solids Handling, they provide comprehensive material testing to all customers. These tests help identify the optimal screw feeder configuration for your specific application, accounting for factors such as particle size, density, and flow characteristics.
The Impact of Material Characteristics on Flow
All materials behave differently, and these variations can affect a screw feeder’s performance and dosing accuracy. Testing materials in advance identifies potential issues before the design phase and enables Trantec to develop feeders of optimal configuration, ensuring smooth operation, precise dosing and avoiding costly downtime.
Key properties evaluated during testing include particle shape and size, bulk and tapped density, moisture content, cohesiveness, flowability, friability, abrasiveness, and stickiness. Understanding these characteristics predicts material behaviour in real conditions and helps fine-tune feeders to the customer’s application.
Testing also highlights specific challenges and their effects, for example, irregular particles can cause bridging, low or variable density can lead to inconsistent volumetric feeding, and high moisture or sticky materials can clump or adhere to surfaces. For unique or unusual materials, testing provides deeper insight, helping engineers understand potential issues and develop customised feeding solutions. This knowledge ensures reliable and efficient performance, even with materials that behave unpredictably in standard systems.
Preventing Flow Problems with the Right Agitator
To overcome challenges such as bridging, rat-holing, and inconsistent flow, Trantec offers a versatile range of agitators designed to match specific material behaviours. Fragile powders receive gentle, low-impact agitation to prevent degradation, while dense, cohesive, or sticky materials require robust designs to maintain continuous movement.
Each agitator is engineered using hands-on testing and material handling expertise, ensuring uniform flow and reliable long-term operation, even with difficult-to-handle materials.
Augers Tailored to Your Material
Through their specialist division, Augers UK, Trantec manufactures bespoke augers in endless configurations to suit different materials and throughput requirements. Options may include single-start and twin-start designs, variable or constant-pitch augers, precision micro augers for ultra-low dosing, segmented cores, and variable flight patterns with custom diameters and lengths. Every auger is designed to achieve uniform flow, minimal material degradation, and accurate dosing, also guided by comprehensive material testing.
Hands-On Trials for Optimal Performance
Trantec’s state-of-the-art testing facility houses a wide range of screw feeders, augers, and agitators, enabling rapid trials with your material. These hands-on trials fine-tune feeders specifically to the customer’s material, providing insight into how it behaves under real operating conditions.
