What is Sludge-Based Organic Fertilizer? Sludge-based organic fertilizer refers to an organic soil conditioner made from dewatered sludge produced by municipal wastewater treatment plants through processes such as heavy metal stabilization, aerobic fermentation, and deep composting. Sludge contains abundant organic matter (30% to 50%), nitrogen and phosphorus nutrients (2% to 4% nitrogen, 1% to...

In the context of modern agriculture’s pursuit of sustainable development, fertilizer production is undergoing a paradigm shift from single chemical synthesis to a synergistic approach of bio-organic processes. Whether processing organic waste such as empty fruit bunches (EFB) from oil palm or constructing high-yield fertilizer production lines, understanding the technological differences between...

What is Humic Acid Fertilizer? Humic acid fertilizer is a type of functional fertilizer made from peat, lignite, or weathered coal rich in humic acid. Through processes such as alkali extraction, acid precipitation, and compounding, humic acid is converted into a form that can be absorbed by plants and combined with nitrogen, phosphorus, potassium, and trace elements. Humic acid has a triple...

What is Sulfur-Coated NPK Compound Fertilizer? Sulfur-coated NPK compound fertilizer refers to a slow-release fertilizer with a controlled-release structure formed by spraying a layer of molten sulfur onto the surface of NPK granular fertilizer and then covering it with a sealant. The sulfur layer acts as a physical barrier to delay nutrient dissolution, and the sulfate ions released after...

What is the role of urea in NPK granulation? Urea plays a triple role in the granulation process of NPK compound fertilizer: nitrogen nutrient carrier, liquid-phase binder, and granulation solubilizer. Its unique physicochemical properties—high nitrogen content (46.2%), easy hygroscopic solubility, and low melting point (132.7 degrees Celsius)—make it the most active component in the drum...

What is an NPK compound fertilizer production line for the African and Southeast Asian markets? A nitrogen, phosphorus, and potassium (NPK) compound fertilizer production line for the African and Southeast Asian markets refers to a complete industrial system adapted to the constraints of tropical climates, unstable power supply, weak logistics infrastructure, and unique local raw...

What is a Sheep Manure Processing Production Line? A sheep manure processing production line refers to a complete set of equipment that uses sheep manure as a single or core raw material, transforming it into commercial organic fertilizer through processes such as solid-liquid separation, aerobic fermentation, crushing and screening, granulation, and packaging. Sheep manure has a...

What is a Mobile windrow composting machine? A mobile windrow composting machine is a self-propelled aerobic fermentation device that can move freely in open-air or indoor windrow composting machine yards. Unlike trough compost turners that rely on fixed tracks, mobile compost turners straddle the windlass or move along its side, using high-speed rotating cutter rollers or drums to...

 What is Industrial-Grade 20-20-20 Water-Soluble Fertilizer? 20-20-20 water-soluble fertilizer refers to a balanced, water-soluble compound fertilizer with 20% nitrogen, 20% phosphorus pentoxide, and 20% potassium oxide. It is the most representative general-purpose formula among water-soluble fertilizers. Industrial-grade products require raw material purity higher than 98%, water-insoluble...

What is a Disc Granulator? A disc granulator is a device that uses the rotating motion of an inclined disc to agglomerate powdery materials into spherical granules. It is widely used in the production of compound fertilizers, organic fertilizers, and blended fertilizers. Its core working principle is: the material rises to a certain height within the rotating disc and then rolls down...
