A vibrating screening machine is a commonly used equipment for particle separation and classification. It works by placing granular materials on a screening surface, where vibration forces cause the particles to move, separate, and classify according to size. This equipment is highly effective for screening and grading various materials such as granules, powders, and colloids. Common types include circular vibrating screens, linear vibrating screens, and high-frequency vibrating screens.
I. Product Overview:
The Fertilizer Vibrating Screening Machine is a key classification device widely applied in the production lines of organic fertilizers, compound fertilizers, bio-fertilizers, and various granular fertilizers. Its primary function is to classify fertilizer granules by size and remove impurities after granulation, drying, and cooling. This ensures uniform particle distribution, clean appearance, and consistent product quality. By using high-frequency vibration to achieve precise classification, the machine significantly enhances automation levels, reduces labor costs, and minimizes screening errors.
As modern agriculture advances toward efficiency, sustainability, and smart production, fertilizer granule uniformity has become a key market competitiveness indicator. Traditional manual or rotary drum screening methods suffer from low efficiency, screen clogging, and inconsistent precision. The vibrating screening machine overcomes these limitations through multi-layer screening surfaces and adjustable vibration frequency technology, allowing accurate screening of materials with varying particle sizes, moisture content, and textures. It is now an indispensable component for fertilizer producers aiming to improve both quality and capacity.
Zhengzhou Yizheng Heavy Machinery Co., Ltd. designs and manufactures high-reliability vibrating screens known for excellent performance, stable operation, and long service life. Drawing from extensive industry experience, Yizheng’s models are ideal for small, medium, and large fertilizer production lines, making them the preferred choice for modern fertilizer plants.
II. Working Principle:
The core principle of the vibrating screening machine is to generate vibration forces through an excitation device, causing the material to move in a jumping motion across the screen surface, achieving classification and separation. The system typically consists of a screen box, vibrating motor, damping device, frame, and control system.
1. Excitation Drive
Equipped with dual vibrating motors or a single-shaft exciter, the system produces centrifugal inertial force during high-speed rotation, driving the screen box to vibrate periodically. Adjusting the motor’s eccentric weight and frequency controls the amplitude and material trajectory to suit different fertilizer characteristics.
2. Material Motion and Classification
Fertilizer granules fed onto the screen surface move directionally under vibration. Small particles fall through the screen openings to form undersized products, while larger ones move forward for discharge. Double- or triple-layer screens are commonly used to obtain two or three distinct particle size fractions simultaneously.
3. Screen Mesh and Anti-Clogging Design
The screens can be made of stainless steel woven mesh, perforated steel plates, or polyurethane anti-blocking panels with anti-adhesion coatings, ideal for moist or sticky fertilizer granules. The quick-release frame design simplifies replacement and cleaning.
4. Damping and Support System
Rubber springs or composite dampers beneath the screen box absorb vibration effectively, reducing operational noise and structural load. The system maintains excellent dynamic balance, allowing continuous operation without resonance.
5. Intelligent Control System
Advanced models can be equipped with PLC-based control, enabling automatic start/stop, throughput monitoring, clog detection, and frequency adjustment. Integration with remote monitoring systems supports intelligent production management.
III. Product Applications:
The vibrating screening machine has broad applications across fertilizer processing and other industries involving granular or powder materials. Key uses include:
1. Organic Fertilizer Production Lines
Classifies fermented, granulated, and dried organic fertilizer particles, removing unformed or broken granules to ensure uniform, high-quality output.
2. Compound and Inorganic Fertilizer Lines
Used after granulation and cooling to eliminate fines and oversized particles, improving appearance and gradation consistency before packaging.
3. Bio-Organic and Microbial Fertilizer Production
Suitable for materials containing active microorganisms; gentle vibration ensures screening without damaging microbial viability or reducing fertilizer effectiveness.
4. Livestock Manure Composting Systems
Performs pre-screening and impurity removal after composting, separating undecomposed lumps and non-organic residues to enhance granulation efficiency.
5. Feed, Chemical, and Recycling Industries
Applicable for classifying feed ingredients, chemical powders, and dried sludge particles—demonstrating high versatility beyond fertilizer use.
IV. Product Features:
1. High Screening Efficiency and Adjustable Precision
Dual vibration excitation technology achieves over 90% screening efficiency. Vibration amplitude and screen inclination can be adjusted for multi-specification fine screening.
2. Robust Construction and Stable Operation
Built from high-strength welded steel with dynamically balanced components, the machine operates smoothly without resonance—ideal for continuous, long-term operation.
3. Strong Adaptability and Wide Application Range
Suitable for powder, granular, moist, or dry materials; particularly effective for sticky or wet organic fertilizer particles.
4. Anti-Clogging and Self-Cleaning Design
Equipped with rubber ball cleaning devices under the screen surface to prevent clogging and ensure consistent efficiency.
5. Easy Maintenance and Long Service Life
Simple motor maintenance, dust-proof bearings, quick-release screen mesh design, and anti-corrosion treatment make it ideal for humid environments.
