Specifications of China rotary drum scraper roller dryer for fertilizers

The China rotary drum scraper roller dryer is a robust and efficient industrial drying solution designed for processing fertilizers, including organic and compound varieties. It utilizes a rotating drum combined with an integrated scraper system to ensure uniform drying, prevent material buildup, and enhance heat transfer. The dryer is constructed from high-grade stainless steel (typically SS304 or SS316) for corrosion resistance, durability, and compliance with fertilizer industry standards. The drum diameter ranges from 1.2 to 3.5 meters, with lengths spanning 6 to 25 meters, accommodating varying production scales. Rotation speeds are adjustable between 2 to 8 RPM, powered by a 5.5 to 55 kW motor, depending on the model. Operating temperatures range from 80°C to 600°C, adjustable via gas, steam, or electric heating systems to suit material requirements. The dryer’s capacity varies from 500 kg/hour for small-scale operations to 20 tons/hour for large industrial setups. Thermal efficiency is optimized at 70–85%, reducing energy consumption. The built-in scraper mechanism continuously removes adhered materials from the drum’s inner surface, ensuring consistent drying and minimizing downtime. An automated control system monitors and adjusts temperature, rotation speed, and moisture levels, enhancing precision. Safety features include overload protection, temperature sensors, and emergency stop functions. The dryer is suitable for granular, powdery, or pelletized fertilizers, as well as biomass, sludge, and minerals. Customization options include drum coatings, dust removal systems, and heat recovery units. Benefits include reduced moisture content (to 5–15%), improved product quality, and extended shelf life. Compliant with ISO and CE standards, it is ideal for fertilizer plants seeking scalable, low-maintenance drying solutions. After-sales support typically includes installation guidance, maintenance training, and spare parts supply. Specifications may vary based on manufacturer and client requirements.

Applications of China rotary drum scraper roller dryer for fertilizers

The China rotary drum scraper roller dryer is a highly efficient and versatile drying solution widely used in the fertilizer industry for processing organic and inorganic fertilizers. Its robust design, combined with advanced thermal efficiency, makes it ideal for handling moisture-rich materials, ensuring consistent drying results while preserving nutrient integrity. This equipment is particularly suited for large-scale fertilizer production, offering reliability and adaptability to various raw materials, including granules, powders, and sludge-based fertilizers.

One key application is drying organic fertilizers, such as composted animal manure, agricultural waste, and bio-sludge. The rotary drum’s gentle tumbling action, aided by internal scraper blades, ensures even heat distribution and prevents material clumping. This process reduces moisture content to optimal levels (typically below 15%), enhancing storage stability and preventing microbial degradation. For inorganic fertilizers like NPK blends, ammonium sulfate, or urea, the dryer efficiently removes residual moisture post-granulation, ensuring uniform particle size and preventing caking during storage.

The system’s indirect heating mechanism minimizes direct contact between heat sources and fertilizers, preserving chemical properties and reducing the risk of nutrient loss. Adjustable temperature settings (typically 80–300°C) and rotational speed allow customization for heat-sensitive materials, such as biofertilizers containing live microorganisms. Additionally, the dryer supports waste-to-resource initiatives by processing byproducts like municipal sludge or industrial organic waste into nutrient-rich fertilizers, aligning with sustainable production practices.

Energy efficiency is a standout feature, with many models incorporating heat recovery systems to reuse exhaust heat, lowering operational costs and carbon footprints. The corrosion-resistant stainless steel construction ensures durability in harsh, high-moisture environments. Its automated control system enables precise monitoring of moisture levels, temperature, and throughput, reducing labor dependency and enhancing productivity.

In summary, the China rotary drum scraper roller dryer is indispensable for modern fertilizer manufacturing, offering scalability, energy savings, and adaptability to diverse materials. Its applications span organic and synthetic fertilizer production, waste recycling, and specialty biofertilizers, making it a critical asset for producers aiming to meet quality standards and environmental regulations efficiently.

5 FAQs of China rotary drum scraper roller dryer for fertilizers

What is a rotary drum scraper roller dryer used for in fertilizer production? A rotary drum scraper roller dryer is designed to efficiently reduce moisture content in fertilizer materials through a heated rotating drum. The system uses internal scrapers to evenly spread and turn the material, ensuring consistent drying. It is ideal for bulk processing of granules, powders, or pellets, making it a critical step in producing stable, high-quality fertilizers ready for packaging or further processing.

How does the rotary drum scraper roller dryer work? The dryer operates by feeding wet fertilizer into a rotating drum heated indirectly via hot air, steam, or thermal oil. As the drum rotates, internal scraper blades lift and cascade the material, exposing it uniformly to heat while preventing clumping. Moisture evaporates, and dried fertilizer exits through a discharge port. The scraper system ensures minimal residue buildup, optimizing heat transfer and drying efficiency.

What types of fertilizers can this dryer handle? This dryer is versatile and suitable for organic fertilizers, compound fertilizers, NPK blends, and biofertilizers. It accommodates materials ranging from powdery compost to granular formulations. The adjustable temperature and rotational speed allow customization for heat-sensitive or high-moisture inputs, ensuring gentle yet effective drying without degrading nutrient content.

Is the rotary drum scraper roller dryer energy-efficient? Yes. The design maximizes heat utilization through indirect heating and insulated drum walls, reducing energy waste. Many models support alternative heat sources like biomass, biogas, or waste heat recovery systems, lowering operational costs. Efficient airflow management and scrapers that prevent material stagnation further enhance energy savings, making it a cost-effective choice for large-scale operations.

What maintenance is required for this dryer? Maintenance is minimal but critical. Regularly inspect and clean scrapers to prevent wear and ensure smooth operation. Check seals, bearings, and heating elements for damage. Lubricate rotating parts as per manufacturer guidelines. High-quality dryers from China often use corrosion-resistant materials like stainless steel, extending lifespan. Schedule annual professional servicing to address wear and optimize performance, ensuring consistent output and reducing downtime.
