The vibrating grading sieve offers efficient screening for feed and biomass pellets, removing fines and oversized particles to ensure uniform quality. Its low noise, simple design, and customizable mesh options help streamline production and boost profitability.
The vibrating grading sieve is a vital screening device extensively used in animal feed pellet plants, aquatic feed production lines, poultry and livestock feed factories, as well as biomass pellet production lines (e.g., wood pellets, straw pellets, husk pellets). Its core function is to separate qualified finished pellets from fines and oversized particles, ensuring a consistent and high-quality final product ready for packaging.
Operating on the probability screening principle, this machine combines controlled vibratory motion with appropriately sized screen meshes and adjustable screen inclination to achieve efficient grading. Its optimized design ensures dust-free, low-noise, and high-efficiency performance, making it a reliable choice for pellet quality control across a wide range of applications in the feed and biomass industries.
If feed pellets are directly packaged without undergoing screening, fine powder and oversized particles may be included in the final product. This lowers product quality, compromises nutritional uniformity, and negatively impacts customer satisfaction and profitability.
Integrating a vibrating grading sieve in the pelletizing line allows you to:
✅ Remove fine powder and oversized particles before packaging.
✅ Reprocess unqualified material by returning it to the pellet mill or crusher.
✅ Ensure pellet uniformity in size, shape, and density.
✅ Improve overall product quality and market competitiveness.
✅ Reduce waste and improve production efficiency.

✅ Adjustable Performance
Screen inclination and vibration amplitude can be easily customized to meet specific material and capacity requirements.
✅ Energy-Saving Operation
Low power consumption with high throughput for cost-effective production.
✅ Adjust Amplitude
Modify the vibration amplitude according to pellet size and quantity. Ensure the motor’s rotation direction matches the pellet flow direction.
✅ Pre-Startup Inspection
Check damping springs, vibration motors, and electrical connections to ensure proper functioning.
✅ Startup Without Load
Start the motor under no-load conditions. Begin feeding only after the sieve reaches stable operation.
✅ Uniform Feeding
Feed materials steadily within the rated capacity to avoid overloading and uneven distribution.
✅ Shutdown Procedure
Stop feeding before shutting down the machine to prevent residual buildup.
✅ Routine Maintenance
Regularly clean, inspect, and repair the sieve components to ensure long-term reliability.
✅ Mesh Shape Matters
Rectangular meshes are suitable for cylindrical pellets.
Round meshes are ideal for irregular-shaped pellets.
✅ Optimize Feeding Distribution
When feeding directly from a bucket elevator, materials may pile up in the center, reducing screen efficiency.
Install a buffer hopper with a flow deflector to evenly distribute material across the screen.
✅ Screen Angle and Mesh Size Combination
Use larger mesh openings along with an appropriate screen angle to achieve finer separation without increasing sieve size.
Make a Quick Inquiry Now !✅ Q1: What materials can be processed with this sieve?
A: It’s suitable for screening various pelletized materials including animal feed, aquatic feed, and biomass fuel pellets.
✅ Q2: How do I choose the right screen mesh size?
A: Choose a mesh size slightly larger than your desired pellet diameter. For example, for 4mm pellets, use a mesh size around 4.2–4.5mm.
✅ Q3: Can it be used both before and after pelletizing?
A: Yes. Use it after pelletizing to sort final products, or after crushing to separate usable fines for reprocessing.
✅ Q4: Is it easy to clean and maintain?
A: Yes. The machine is designed with a simple structure and stainless steel screen for easy maintenance and sanitation.
✅ Q5: What is the power consumption of the machine?
A: Power consumption varies by model, typically ranging from 0.5 kW to 2.2 kW. It is energy-efficient for continuous operation.
✅ Q6: Can I replace the screen mesh?
A: Yes. The screen mesh is replaceable, and different mesh sizes can be selected based on production requirements.
✅ Q7: How does it help improve production efficiency?
A: By removing unqualified materials and reducing product rework, the vibrating grading sieve helps streamline production, improve product quality, and enhance operational efficiency.
