When it comes to bulk material feeding, not all materials are created equal. Factors like particle size, density, moisture content, and flowability can make or break a feeding system’s performance. Understanding the science behind material flow is crucial for ensuring consistent feeding, reducing waste, and preventing costly production delays.
At Orbetron, we specialize in solving material flow challenges through advanced feeding solutions tailored to the properties of the materials being handled. In this blog, we’ll explore the common obstacles in bulk feeding and how to overcome them.
Understanding Material Flow Properties
Every material has unique characteristics that affect how it flows through a feeding system. Here are some key properties to consider:
- Particle Size and Shape: Fine powders behave very differently from larger granules. Irregularly shaped particles are more prone to clumping or bridging (blocking the flow).
- Density: Materials with high bulk density require different feeding strategies compared to lightweight materials.
- Moisture Content: High moisture levels can make materials sticky, leading to clogging and inconsistent feeding.
- Flowability: Materials with poor flowability (e.g., cohesive powders) tend to stick to the walls of feeders, causing disruptions.
Understanding these properties is the first step in selecting or designing the right feeding system.
Common Challenges in Bulk Feeding
- Bridging and Ratholing: Some materials form bridges or channels inside hoppers, preventing consistent flow.
- Inconsistent Feed Rates: Materials with variable density or flowability can lead to irregular feed rates, compromising product quality.
- Dust Generation: Fine powders can create dust during feeding, posing safety and environmental concerns.
- Material Degradation: Fragile materials may break down during feeding, affecting their performance in the final product.
How Orbetron Solves Material Flow Challenges
1. Custom-Designed Feeders for Material Properties
At Orbetron, we design feeders that cater to the specific properties of the material being handled. For example:
- Disc Feeders are ideal for free-flowing materials like granules.
- Twin Screw Feeders (OTS-Micro) excel at handling cohesive powders by using dual screws to maintain consistent flow.
2. Advanced Agitation Mechanisms
Our feeders can be equipped with agitators to prevent bridging and ensure consistent flow. These mechanisms gently break up clumps, allowing materials to move freely through the system.
3. Real-Time Monitoring
Orbetron’s gravimetric feeders use real-time weight measurements to adjust feed rates automatically. This ensures consistent material delivery, even for materials with variable properties.
4. Dust Control Solutions
Our closed systems minimize dust generation during feeding, creating a safer and cleaner work environment.
Applications of Orbetron’s Feeding Solutions
Our feeding systems have been used to overcome material flow challenges in various industries:
