From chicken manure in Southeast Asia to municipal sludge in Europe, the raw materials feeding today's organic fertilizer lines are anything but uniform — and that's exactly what shapes how we design our fertilizer granulator machines. Over the years, we've commissioned pellet production projects across more than 60 countries, and the one thing every successful plant has in common is equipment matched to the actual feedstock, moisture content, and output target of that specific site.

Our fertilizer granulator machine range was built around exactly practical decisions: output volume, pellet density, raw material consistency, and what the end market demands. Whether you're running a 500 kg/h composting operation or planning a 20 t/h commercial organic fertilizer facility, the equipment configuration looks very different. Browse through our full product series below — models, specs, application examples, and real project references are all here.

Our fertilizer granulator machine lineup is organized by raw material type, because that's how real production decisions get made. Whether you're processing fresh livestock waste, municipal sludge, fermentation residues, or crop stalks, NPK, the machine configuration, die spec, and moisture handling requirements are all different. Below is a breakdown of our main product categories, the materials they're designed for, and the customers who typically run them.
● Livestock & Poultry Waste
● Municipal & Industrial Wastewater Byproducts
● Mixed Organic Waste Streams
● Mineral-Enhanced Organic Blends
● Mixed & Blended Nutrients
● Crop Residues & Plant-Based Byproducts
● Fermentation Byproducts & Processing Residues

The ring die runs under continuous radial load. Bearings here are sized for that specific stress pattern, not generic replacements. Typical service intervals run 2,000–3,000 hours under normal organic material loads.
Torque stays consistent even when feedstock moisture shifts mid-run. Less thermal buildup, fewer unexpected stops during long production shifts.
Machined from alloy steel with compression ratios selected by material type. Die hole geometry directly affects pellet density and surface hardness — not something to standardize across all feedstocks.
A screw feeder pushes material into the die chamber at a controlled rate. The arch-breaking device above it prevents compacted or sticky organic material from bridging in the hopper and blocking feed flow.
Most ring die failures in organic fertilizer applications come down to three things: wrong die spec for the material, drive systems that can't handle load variation, and bearings that were never rated for continuous heavy-duty use. Each fertilizer granulator machine we build is configured around the actual feedstock — compression ratio, die thickness, and motor sizing are not fixed defaults. Customers processing high-fiber agricultural residues need a different die geometry than someone running composted sludge at 35% moisture. We've worked through enough of these combinations across projects in South Asia, Africa, and Eastern Europe to know which configurations hold and which ones don't make it past the first 500 hours.

Reading spec sheets only tells part of the story. These two videos show actual fertilizer granulator machine installations — different countries, different raw materials, different plant scales. One plant in Germany processing chicken manure and winery waste, another in Russia handling livestock manure mixed with straw. Both built and commissioned by our team. If you're planning a similar project or working with comparable feedstocks, these are worth watching before you start specifying equipment.

Across more than 60 countries, we've supplied complete fertilizer production lines to livestock farms, municipal waste operators, food processing companies, and agricultural cooperatives. In most of these projects, the fertilizer granulator machine is one part of a larger system — we typically deliver full granular or powder fertilizer lines covering organic fertilizer, compound fertilizer, and NPK processing. The cases above are a cross-section of what we've built: different raw materials, different output targets, different industries, but the same core question every client started with — what do I do with this material, and can I turn it into something sellable?
○ RICHI MACHINERY
The fertilizer granulator machine is one part of the process. What goes before and after it determines whether the whole line actually works. We supply complete fertilizer production lines — granular organic fertilizer lines, powder organic fertilizer lines, NPK compound fertilizer lines, and modular systems for drying, batching, and blending. Every line is configured around the client's actual raw material, moisture content, plant dimensions, and budget. Some process stages are fixed. Others depend entirely on what you're processing and what product you need at the end.

A complete line typically runs through crushing, mixing, composting, drying, granulation, cooling, screening, and packaging — but which stages your line actually needs depends on what you're starting with. Fresh chicken manure at 65% moisture follows a completely different process path than dry straw blended with composted cow dung, and the equipment at each stage changes accordingly.
From initial consultation through equipment manufacturing, installation, commissioning, operator training, and spare parts supply — we cover the full working life of the line.

Most organic waste streams and a wide range of mineral inputs can be processed into fertilizer pellets — single-source or blended. Our fertilizer granulator machine handles materials from livestock farms, food processing plants, municipal waste treatment, agricultural residues, and industrial fermentation byproducts. Below is a reference list of commonly processed materials.
High nitrogen, widely available from poultry farms. Works standalone or blended with dry carbon materials to balance moisture before granulation.
Higher fiber, lower nitrogen than poultry manure. Standard feedstock for dairy and beef operations converting waste into organic fertilizer.
Moderate fiber and nutrient content, lower moisture than most poultry manure. Common among equestrian centers, horse farms, and racing stable operations.
Nutrient-rich with moderate moisture. Suitable for hog farms processing on-site or supplying to centralized fertilizer production facilities.
Dry, low-odor, easy to handle. Common among sheep ranches and small organic fertilizer producers targeting certified organic markets.
Low moisture, high nutrient density. Favored by rabbit farming operations for direct granulation with minimal pre-drying required.
Moderate nutrient profile from waterfowl operations. Often blended with straw or crop residues to improve granulation consistency.
Similar handling profile to duck manure. Available from goose farming operations and mixed poultry facilities.
Collected from food processing plants, canteens, and markets. Requires composting or dewatering before entering the granulation line.
Pre-processed organic material with stable moisture and particle size. One of the most straightforward feedstocks for direct granulation.
Generated by industrial wastewater treatment. High moisture requires mechanical dewatering and drying before granulation.
From urban wastewater plants. Nutrient-dense but requires odor control and enclosed processing depending on local regulations.
Spent grain and yeast residues from beer production. Moderate moisture, available in large volumes from brewing facilities.
Pruning residues and fruit processing byproducts. Requires size reduction before blending into the fertilizer granulation process.
Treated sewage-derived material meeting land application standards. Used by municipal operators and environmental service companies.

Every line we quote is configured around the client's actual raw material, process requirements, and site conditions — so the price range for any given capacity reflects real variation, not a rough estimate. The figures below are based on thousands of design proposals and quotations we've completed across projects in more than 30 countries. Each range covers a complete equipment package including the fertilizer granulator machine, pre-treatment equipment, drying system, cooling, screening, and packaging — not individual machines. Where the number lands within that range depends on material type, automation level, and which optional stages the process requires.
○ RICHI MACHINERY
Removes stones, metal fragments, wire, plastic, and other contaminants from incoming organic material before processing begins. Skipping this stage is one of the most common causes of premature die wear on the granulation machine.
Reduces particle size of dry or semi-dry organic material to the range required for consistent mixing and granulation. Material hardness, moisture, and fiber content determine which crusher type fits.
Handles fermentation and homogenization of raw organic inputs before drying or direct granulation. For high-moisture materials like fresh manure or food waste, this stage stabilizes the feedstock and reduces pathogen levels. For blended inputs, it homogenizes moisture and nutrient distribution.
Controls moisture content before the material enters the fertilizer granulator machine — one of the most critical variables in pellet quality and die longevity. Target moisture at the granulator inlet is typically 12–18% depending on material type.
05/01
Granules exit the ring die at 70–90°C and need to be brought down to near ambient temperature before screening and bagging. Skipping cooling leads to pellet deformation, surface cracking, and moisture reabsorption during storage.
05/01
Applies a surface treatment to finished pellets to improve appearance, reduce dust, extend shelf life, or add functional coatings for slow-release formulations. Common in export-grade fertilizer production and premium retail product lines.
05/01
Packages finished fertilizer into bags for storage, transport, or retail sale. Bag format, fill weight, and automation level vary widely by market and client scale.
05/01
Moves material between every stage of the line — horizontal transfer, inclined elevation, and distribution to multiple processing points. Conveyor layout is designed around plant building dimensions and process flow sequence.
05/01
Stores raw materials, intermediate process materials, or finished fertilizer before bagging or dispatch. Particularly important for lines running continuous shifts where buffer capacity between stages prevents bottlenecks.

Prices vary based on configuration and destination. Complete production line pricing starts from $39,000 depending on capacity and process requirements.
Most organic waste streams work — chicken manure, cow dung, pig manure, sewage sludge, biogas digestate, food waste, agricultural residues like straw and bagasse, and industrial fermentation byproducts. Mineral inputs including NPK blends, bentonite, and phosphate mixtures can also be granulated on dedicated compound fertilizer lines. Two or more materials are often combined before granulation. If you're unsure whether your feedstock is suitable, send us a material description and we'll give you a direct answer.
Output capacity is the starting point — our FZLH series runs from 1 t/h on the FZLH250 up to 22–26 t/h on the FZLH768. But model selection also depends on raw material type, moisture content going into the machine, and target pellet diameter. We've completed thousands of equipment proposals across projects in more than 30 countries. Tell us your material and daily output target and we'll recommend the right model with supporting data from comparable projects.
It depends on your raw material condition. If your feedstock is already dried and crushed to consistent particle size, a standalone fertilizer granulator machine can work. In most real-world situations, the material needs pre-treatment — drying, crushing, composting, or a combination — before it reaches the granulator. We supply both standalone machines and complete lines. If you're not sure what your process actually needs, we can walk through it based on your raw material specs.
Pellet diameter is adjustable between 4mm and 12mm across all FZLH models by changing the ring die. The right size depends on your target market — bulk farm application typically uses 4–6mm, while retail-packaged products often go to 6–8mm. Die hole geometry also affects pellet density and hardness, which we configure based on material type.
Under normal operating conditions with organic fertilizer inputs, a correctly specified ring die runs 800–1,200 hours before replacement is needed. Die life shortens significantly if moisture going into the machine is outside the 12–18% range, or if abrasive mineral content is higher than anticipated. We stock replacement dies for all FZLH models and can ship within a few days for most destinations.
We cover installation supervision, commissioning, operator training, and spare parts supply — from startup through the full working life of the line. Remote troubleshooting is available via video for most operational issues. For large projects, on-site engineers are arranged during the commissioning phase. Spare parts including ring dies, rollers, bearings, and wear components are stocked and available for dispatch from our facility in Henan, China.
Standard single machines ship in 15–25 days. Complete production lines take 30–60 days for manufacturing depending on line scale and configuration complexity. Delivery time to most destinations adds 20–35 days by sea freight. We provide a detailed production and delivery schedule at the time of order confirmation.
Yes — and most of our clients process more than one feedstock. A mixed livestock farm running chicken manure, cow dung, and pig waste in different seasons is a common example. The line is configured for the most demanding material in your feedstock range, and die selection can be adjusted when switching between materials. We've built multi-feedstock lines in New Zealand, Paraguay, Ukraine, and several other markets where seasonal material availability varies.
Start with your raw material — type, daily volume, and moisture content. That determines the process stages you need, which determines equipment selection, which determines line layout and civil requirements. We've taken hundreds of clients through this process from the first conversation to a commissioned plant. Share your material details and output target with our team and we'll put together a process flow and preliminary equipment list at no charge.
