Rotary dryer

Product Features (Fertilizer Industry-Specific)

With “solving fertilizer drying pain points, protecting nutrients & ensuring production efficiency” as the core goal, our fertilizer dryers integrate targeted technologies:

  • High-Efficiency Moisture Removal for Fertilizer Types:

For organic fertilizer: Adopt “multi-layer mesh belt + hot air circulation” design, reducing moisture from 60%-80% to 15%-20% (standard for fertilizer storage) in 30-60 minutes, avoiding bacterial regrowth;For chemical fertilizer: Use “rotary drum + indirect heating” technology (preventing direct contact between hot air and corrosive granules), ensuring uniform drying and no granule cracking.

  • Nutrient Protection & Corrosion Resistance:

Organic fertilizer: Low-temperature drying (50-70℃) with heat recovery system, retaining 95%+ of organic matter (e.g., humic acid) and beneficial bacteria (avoiding high-temperature inactivation);

Chemical fertilizer:for mild corrosion or for strong acid/alkali, resisting ammonia/phosphate erosion, extending service life.

  • Anti-Caking & Easy Cleaning:

Equipped with anti-caking device and “polishing plate”, reducing caking rate from 30% to ≤5%;Smooth inner wall design with high-pressure water cleaning port, cutting manual cleaning time by 70% (critical for batch fertilizer type switching).

Application Scenarios (Fertilizer Production Links)

Our fertilizer dryers cover all moisture-removal links of fertilizer production lines:

  • Organic Fertilizer Post-Fermentation: Mesh belt dryers for fermented manure/straw mixtures (moisture 65%-75%), drying to storage-standard moisture (15%-18%) without damaging beneficial microbes.
  • Chemical Fertilizer Granule Drying: Rotary drum dryers for compound fertilizer/ammonia phosphate granules (post-granulation), ensuring uniform moisture (≤1% for packaging) and no granule deformation.
  • Biological Fertilizer Drying: Low-temperature vacuum dryers (40-55℃) for microbial fertilizer, retaining 98%+ of viable bacteria (e.g., nitrogen-fixing bacteria), meeting biological fertilizer GB/T 23473 standards.
  • Small-Batch Fertilizer Processing: Mobile belt dryers (for 500-5,000 tons/year workshops) with flexible installation, suitable for organic fertilizer workshops with limited space.
  • Large-Scale Continuous Production: Multi-drum series dryers (for 50,000+ tons/year plants) with continuous feeding/discharging, matching 24/7 fertilizer production lines (daily output 150-500 tons).

Pricing System

Adopt “factory direct supply + fertilizer line customization” with no middlemen, cutting procurement costs by 18%-30% vs. general industrial dryers:

Why Choose Us for Fertilizer Dryers?

As a dryer supplier specialized in fertilizer industry, we offer targeted solutions beyond equipment:

  • Industry Expertise: 10-person R&D team (8+ years in fertilizer drying), holding 12 national patents (e.g., “Low-Temperature Organic Fertilizer Drying System”, “Anti-Corrosion Chemical Fertilizer Dryer Drum”);
  • Tailored Customization: Analyze fertilizer type (organic/chemical/biological), raw material moisture (40%-80%), and production capacity to adjust dryer structure — e.g., adding heat preservation layers for cold-region workshops, or acid-resistant liners for high-phosphate fertilizer.

Proven Success Cases:

A 50,000-ton/year organic fertilizer plant in China reduced drying energy consumption by 23% and retained 96% of humic acid with our mesh belt dryer;

A Brazilian compound fertilizer plant solved granule cracking issues, increasing qualified product rate from 88% to 99% with our anti-corrosion rotary dryer;

A U.S. biological fertilizer enterprise retained 99% of viable bacteria, meeting EPA organic fertilizer standards with our low-temperature vacuum dryer.

FAQ

(1) Insufficient heat supply, such as a malfunction of the burner resulting in insufficient hot air temperature, or insufficient hot air volume, preventing adequate heat exchange with the fertilizer. (2) Inconsistent fertilizer feed volume, fluctuating between excessive and insufficient. When the feed volume is too large, excessive fertilizer accumulates in the dryer, preventing hot air from penetrating and resulting in insufficient drying; when the feed volume is too small, the heat cannot be fully utilized, and it may even cause some areas of the fertilizer to become overly dry. (3) The rotation speed of the dryer drum is inappropriate. If the speed is too fast, the fertilizer stays in the drum for a short time, resulting in insufficient heat exchange; if the speed is too slow, the fertilizer is prone to accumulation, which also affects the drying effect. (4) The initial moisture content of the fertilizer is too high, exceeding the design processing capacity of the dryer, leading to incomplete drying.
(1) The insulation performance of the dryer is poor. For instance, if the insulation layers of the drum shell and the hot air duct are damaged or insufficient in thickness, a significant amount of heat will be lost, requiring more fuel to maintain the hot air temperature. (2) Inappropriate selection of the fan or unreasonable operating parameters can result in excessive fan air volume, increasing power consumption and potentially causing the hot air to stay in the dryer for too short a time, thereby reducing heat utilization; if the fan air volume is too small, it cannot ensure adequate contact between the hot air and the fertilizer. (3) The distribution of the fertilizer in the dryer is uneven. Some areas have accumulated fertilizer, resulting in insufficient heat exchange and the need to extend the drying time, increasing energy consumption; while in other areas there is no fertilizer, causing the heat to be wasted. (4) The setting of drying process parameters is unreasonable. For example, if the hot air temperature is too high and exceeds the actual drying requirements, it leads to heat waste; or if the drying time is too long, it results in unnecessary energy consumption.
