The fertilizer screening machine is mainly used for grading the particle size and separating impurities of various fertilizers.
With “solving fertilizer screening pain points, ensuring uniform particles & high efficiency” as the core goal, our fertilizer screening machines integrate targeted technologies:
For sticky organic fertilizer (post-fermentation, moisture 15%-20%): Adopt “high-frequency vibration + anti-stick screen mesh” design—vibration frequency (1500-3000 rpm) breaks up agglomerates, and Teflon-coated screen mesh (1-5mm aperture) prevents fertilizer adhesion, screening efficiency ≥98%;For brittle biological fertilizer (microbial granules, easy to crush): Use “low-amplitude vibration + soft rubber screen frame”—amplitude adjustable (1-5mm) reduces particle collision, damage rate ≤2% (vs. 8%-10% for ordinary screens);For corrosive chemical fertilizer (ammonium phosphate, urea): Screen mesh and frame made of 304/316L stainless steel—resists acid/alkali corrosion, service life extended to 5-8 years.
Multi-layer screen design (2-4 layers, optional aperture 0.5-10mm): Realizes one-time classification of “oversized lumps (＞5mm) + qualified granules (2-5mm) + fine powder (＜2mm)”—oversized lumps are returned to crusher for reprocessing, fine powder is recycled to mixer, material utilization rate ≥99%;Built-in magnetic impurity remover (for chemical/organic fertilizer): Adsorbs metal scraps (nails, iron filings) from raw materials, avoiding damage to downstream packaging machines or mixer blades.
Equipped with “screen self-cleaning system”—rotary brush (for mesh cleaning) and air-blowing device (for fine powder removal) work synchronously with vibration, reducing manual cleaning frequency by 80%;Quick-screen replacement structure: Screen mesh can be disassembled in 15-30 minutes (vs. 1-2 hours for ordinary screens), convenient for switching between different fertilizer particle specifications.
PLC control system connects with upstream crusher/fermenter and downstream mixer/coater—automatically adjusts vibration frequency and feeding speed based on incoming material volume (detected by level sensors), avoiding screen overload;Energy-efficient vibration motor (IE3 level) + optimized vibration structure reduce energy consumption by 15%-20% vs. ordinary screening machines, suitable for 24/7 continuous production.
Sealed screening chamber + dust-collecting port (connectable to fertilizer line dust collectors): Prevents dust leakage during screening (dust concentration ≤5mg/m³), complying with GBZ 2.1 occupational health standards;Emergency stop button and overload protection: Triggers auto-shutdown if screen is blocked or motor overheats, preventing equipment damage.
Our fertilizer screening machines cover the “particle classification & impurity removal” link of various fertilizer production lines, matching different fertilizer types:
High-frequency vibrating screens (2-layer, 3mm/5mm aperture) for fermented manure/straw mixtures—separates unfermented lumps (＞5mm) and qualified granules (2-5mm), improving organic fertilizer uniformity;Example: A 30,000-ton/year organic fertilizer plant uses our screen—qualified product rate increased from 82% to 97%, reducing raw material waste by 15%.
Multi-layer vibrating screens (3-layer, 2mm/4mm/6mm aperture) for post-granulation NPK fertilizer—classifies fine powder (＜2mm, recycled), qualified granules (2-4mm, for packaging), and oversized granules (＞6mm, re-crushed);Example: A 50,000-ton/year compound fertilizer plant reduced unqualified granule rate from 10% to 1.2%, passing national quality inspections.
Low-amplitude vibrating screens (1-layer, 2mm aperture) for microbial fertilizer—avoids granule crushing, ensuring viable bacteria count ≥200 million/g (GB/T 23473 standard);
Example: A U.S. biological fertilizer enterprise uses our screen—microbial survival rate after screening reaches 96%, meeting EPA organic product requirements.
Vibrating screens with magnetic separators for straw/corn cob raw materials—removes stones, metal scraps, and large impurities before crushing/fermentation, protecting upstream crushers;
Example: A Chinese straw-based organic fertilizer workshop reduced crusher maintenance frequency by 40% after using our impurity-removing screen.
Mini vibrating screens (capacity 0.5-2 tons/hour) for small workshops (e.g., family farm organic fertilizer production);High-capacity linear vibrating screens (capacity 5-30 tons/hour) for large plants—supports 24/7 continuous screening, matching high-speed granulation lines.
Adopt “factory direct supply + fertilizer line customization” with no middlemen, cutting procurement costs by 18%-30% vs.
As a screening machine supplier specialized in fertilizer industry, we provide solutions tailored to production needs:
A 50,000-ton/year compound fertilizer plant in China reduced reprocessing costs by $60,000/year with our multi-layer screen;
A Brazilian organic fertilizer enterprise solved screen adhesion issues—screening efficiency increased from 85% to 99%, production capacity up 14%;
A European biological fertilizer brand used our low-amplitude screen—microbial product qualification rate reached 99.5%, expanding to 8 EU countries.
Whether you need to classify organic fertilizer granules, remove impurities from compound fertilizer raw materials, or protect brittle biological fertilizer particles, we provide screening machines that match your production line.
