Anyang Chemical Fertilizer Plant of Anhua Group faced key challenges in particle size classification after granulation on its compound fertilizer production line. The fertilizer particles produced by the drum granulator had an uneven particle size distribution, mixed with large particles, qualified particles and fine powder. To ensure the quality and appearance of finished fertilizers, efficient and precise classification must be carried out; otherwise, it will lead to:
Low qualified rate of finished products: Unscreened unqualified particles are directly packaged, which affects the market competitiveness of products.
High pressure of return material treatment: If large return materials and fine powder are not effectively separated and recovered, they will block the crusher or affect the efficiency of the granulator, increasing energy consumption and material loss.
Dust and environmental protection pressure: Open or inefficient screening is prone to fertilizer dust emission, which does not meet the requirements of modern clean production.
The customer urgently needed a screening system with large processing capacity, high classification accuracy, stable operation, and sealed dust prevention to realize continuous and efficient classification of compound fertilizer particles and improve overall production efficiency.
After in-depth analysis of the customer’s production process, Henan Quanshun Vibration Equipment Co., Ltd. accurately configured 2 sets of YK series circular vibrating screens (model: 2YK1230) for its core post-granulation section. This solution perfectly meets the requirements of compound fertilizer particle size classification and realizes “one-layer screening, three-level separation”.
Core advantages and targeted design of equipment:
Efficient and precise classification: Adopting double-layer screen design (2YK), the upper screen accurately screens out large particle return materials larger than 4mm (return to crusher), the lower screen accurately separates qualified finished particles of 2-4mm (enter cooling and packaging section), and fine powder smaller than 2mm (directly return to granulator), completing three-level treatment with one screening.
Strong anti-clogging and anti-vibration: Adopting motion parameters of small amplitude, high frequency and large inclination angle, combined with strong exciting force generated by block eccentric exciter, it can effectively break the slight agglomeration of fertilizer particles caused by moisture absorption, prevent screen adhesion and clogging, and ensure continuous operation.
Sturdy, corrosion-resistant and durable: The main contact parts of the equipment can be made of 304 stainless steel or carbon steel with special anti-corrosion treatment, which can effectively resist the corrosion of fertilizer raw materials and extend the service life. The structural connection method of ring groove rivets and high-strength bolts ensures the sturdiness and stability of the equipment under heavy load and continuous working conditions.
Environmental protection, sealing and consumption reduction: The whole machine adopts fully enclosed structure design, which effectively inhibits dust overflow and keeps the working environment clean. The flexible connection of tire coupling ensures stable transmission, low noise and low energy consumption, meeting the requirements of energy conservation and environmental protection.
| Parameter Item | Value/Description | How to Solve Fertilizer Screening Pain Points |
| Model | 2YK1230 | Double-layer design, suitable for three-level separation process of “large particles – finished products – fine powder”. |
| Screen Surface Area | 3.6 m² | Provides sufficient screening area to ensure that a single equipment meets the large processing capacity requirements of the production line. |
| Processing Capacity | 43-216 t/h | Wide range of capacity adjustment, which can fully match the production capacity fluctuation and expansion needs of the customer’s compound fertilizer production line. |
| Screen Configuration | Upper screen hole > 4mm, lower screen hole 2mm | Can accurately correspond to national standard (2-4mm) or customer-defined finished product particle size requirements, with high classification efficiency. |
| Vibration Frequency | 13.67-15 Hz | High-frequency design is conducive to fine powder passing through the screen, preventing hole clogging, and is especially suitable for fertilizer materials that are easy to absorb. |
| Double Amplitude | 7-10 mm | Small amplitude design reduces particle breakage while ensuring screening efficiency and protects the finished product rate. |
| Installation Inclination Angle | 15-30° (adjustable) | Adjustable large inclination angle can speed up material flow, increase processing capacity, and is especially suitable for screening fertilizer particles with low water content. |
| Supporting Motor | Y160M-4, 11 kW | Strong power, low energy consumption and high operation economy. |
After the two 2YK1230 circular vibrating screens were put into operation, they quickly became the key core equipment on the compound fertilizer production line, creating significant value for the customer:
Leap in finished product quality: The finished fertilizer has uniform particle size (2-4mm), significantly improved appearance quality, and enhanced market competitiveness.
Maximization of production efficiency: Realized 24-hour continuous and automatic classification, and the processing capacity fully matches or even exceeds the production capacity of the granulation section, becoming a guarantee for production speed-up.
Significant reduction in production costs: Large particles and fine powder are efficiently separated and accurately returned to the front-end process for reuse, improving the comprehensive utilization rate of raw materials and greatly reducing losses.
Win-win situation of environmental protection and maintenance: The fully sealed structure realizes dust-free operation and improves the working environment. The sturdy and durable equipment and anti-clogging design effectively reduce the number of shutdowns for cleaning, with extremely low maintenance costs.
