The vibrating screen is a critical classification and separation device in compound fertilizer production lines. It is mainly used after granulation and drying processes to separate fertilizer particles into different size fractions. It ensures consistent product quality by delivering accurate and efficient particle size classification.
The machine is equipped with rubber balls or ultrasonic cleaning devices. Continuous impact on the screen surface prevents material clogging and ensures uninterrupted operation.
Corrosion-Resistant Customization
The machine supports multiple material options, including Q235 with anti-corrosion coating and full stainless steel 304/316L construction. It can adapt to different fertilizer formulations and harsh working environments.
Fully Enclosed Dust-Proof Design
The vibrating screen adopts a sealed structure to effectively prevent fertilizer dust leakage. This design reduces environmental pollution and protects operators, especially in handling corrosive and fine powder materials.
Multi-Layer Screening System
The vibrating screen can be configured with 2–4 layers of screen decks, allowing a single machine to classify materials into multiple size fractions such as oversized particles, qualified granules, and powder. This ensures uniform particle size and improves the final product quality and appearance.
Flexible Screen Mesh Customization
Various screen mesh sizes can be selected according to product requirements. This allows precise control of fertilizer particle size distribution for different market standards.
Modular Design for Easy Maintenance
Screen decks are designed with a modular structure, allowing quick replacement and minimizing downtime during maintenance.
Structure
Screen Box
The screen box is the main working component. It holds multiple layers of screen meshes and supports material classification through vibration.
Vibration Source
Vibration Motor: Compact and easy to maintain; the preferred choice for NPK fertilizer and fine chemical screening.
Exciter System: Heavy-duty design with superior force; specifically engineered for large-scale mining and aggregate processing.
Screen Mesh
Different mesh sizes can be installed depending on required particle size ranges.
Support Frame
A heavy-duty frame ensures structural stability and reduces vibration impact during operation.
Sealing System
Sealing covers and dust outlets prevent powder leakage and support dust collection systems.
Principle
The vibrating screen operates based on mechanical vibration. Materials are fed onto the screen surface and subjected to continuous vibration.
Under vibration force, particles move forward and stratify. Smaller particles pass through the screen openings, while larger particles remain on the upper layer and are discharged separately.
By using multiple screen layers, materials can be separated into several size fractions in a single operation.

FAQ
1. How to prevent screen clogging when handling sticky NPK fertilizers?
We use an automatic cleaning system with rubber balls to prevent mesh blockage. Ultrasonic cleaning is available for fine powders, ensuring stable and continuous operation even with high-moisture materials.
2. How do you select the right material for different fertilizer types?
We offer material options such as coated carbon steel and stainless steel (304/316L), selected based on fertilizer composition, corrosion level, and operating conditions.
3. Can the vibrating screen be integrated into a complete production line?
Yes. The vibrating screen can be integrated with belt conveyors, bucket elevators, and other equipment to form a complete fertilizer screening system, providing a one-stop solution for classification.
4. What after-sales support and spare parts do you provide?
We offer a one-year warranty and supply standard spare parts such as screen meshes, springs, and seals, ensuring quick replacement and minimal downtime.
