A compost pellet machine compresses fermented organic matter into dense cylindrical pellets. Unlike simple crushing, it uses controlled pressure, not chemical binders. The ring die and rollers shape the material at room temperature, so nutrients stay in the pellet and handling becomes far easier.
Compost Pellet Production
RICHI compost pellet machines turn fermented organic waste into uniform organic fertilizer pellets. By switching ring dies, you can produce different pellet sizes for various fertilizer applications.
Why Make Compost Pellets—and How We Help Powder Compost Producers
Pellets flow better, store longer, and cut dust—real wins in transport and field spreading. But not every market wants pellets. We also support many powder compost producers, helping them improve grinding, mixing, moisture control, and bagging. In our experience, both powder and pellets can be profitable—if the equipment fits the job. The key is matching the process to your material and your buyers. So tell us what you sell—bulk powder, bagged powder, or pellets—and we’ll shape the line around it.

How the Compost Pellet Machine Works
Watch how this compost pellet machine turns smelly, bulky organic waste into uniform, solid organic fertilizer pellets.
This factory test video demonstrates our compost pellet machine operating under real production conditions.
Composted animal manure blended with other organic waste is fed into the pellet machine. You can clearly observe raw material feeding, extrusion, and the discharge of finished organic fertilizer pellets, showcasing the full pelletizing workflow for compost recycling.
Pelletization greatly reduces odors and cuts material volume for simpler storage and transportation. The heat generated during compression provides auxiliary sanitization. This equipment helps farms and compost facilities resolve organic waste pollution while producing marketable fertilizer products.
We provide free on-site factory testing. You may send your compost samples — including chicken manure, mixed organic waste or any fermented raw material. We will run live tests on our compost pellet machine, allowing you to verify pellet quality and machine performance before you place your order.

Основные компоненты
When you’re evaluating a pellet mill, the real question isn’t “what’s the price?”—it’s “what’s inside?” We’ve seen too many plants struggle with cheap castings and undersized bearings. So here’s a straight look at the core parts that determine your compost pellet machine’s reliability, output, and die life.
01
Подающий механизм
Variable-frequency forced feeding keeps material flowing evenly, preventing bridging and blocking in daily compost production.
02
Кольцевая матрица
Alloy-steel, wear-resistant, and easy to change—it shapes the pellet and handles abrasive manure, straw, or sludge.
03
Press roller
Adjustable roller-die gap ensures uniform pressure, so pellets stay dense and the die lasts longer.
04
Lubrication system
Automatic, timed lubrication meters grease to rollers and main shaft—cutting downtime and manual maintenance.
05
Siemens motor
Stable, powerful drive delivers reliable torque for continuous granulation, even with tough fibrous materials.
06

Pellet Production Process
From fermentation to bagging, every compost pellet line is tailored. Here’s how our engineers and investors usually map the process together.
Advantages of RICHI Machinery for Compost Production:
Process steps valued by engineers and investors include:
1.Raw Material Pretreatment
2.Batching & Mixing
3.Pelletizing Process
4.Drying Process
5.Cooling Process
6.Screening & Packaging
Предварительная обработка сырья
First, manure, sludge, or green waste is blended with straw or bulking agents. Then it’s piled and turned every few days—or force-aerated—until stable and odor-free.
Дозирование и смешивание
After fermentation, materials are weighed and mixed with additives like NPK, minerals, or microbes. Uniform blending is the key—it prevents nutrient pockets and keeps every pellet close to the same formula.
Процесс гранулирования
If you want pellets, the mix enters the compost pellet machine. Rollers press it through holes at room temperature. For powder compost, this step is simply bypassed. On-site, we adjust roller gap and feeder speed.
Процесс сушки
Wet pellets go through a rotary or belt dryer. Moisture drops to about 12–15% for safe storage. But be careful—too much heat can damage microbes. In daily production, you need to control temperature and retention time closely.
Процесс охлаждения
Hot pellets then enter a counter-flow cooler. Ambient air passes through the pellet bed, bringing temperature close to room level—this protects bagged product from sweating and caking in storage.
Сортировка и упаковка
A vibrating separates oversize, fines, and finished pellets. Oversize and fines return to the crusher or mixer. Finished pellets go to an automatic packing scale. Dust is collected by a pulse filter.
Auxiliary Equipment Configuration for Compost
Pellet Production
Beyond the main compost pellet making machine, a compost pellet line needs auxiliary equipment. In our experience, conveyors, mixers, dryers, coolers, screens, and packing scales must match your material and output—or bottlenecks appear. The key is integration.

FAQ About Compost Pellet Production
Before you invest, it’s smart to ask practical questions. In our experience, buyers care most about moisture, capacity, die life, maintenance, and whether one machine can handle different compost recipes. Below are the questions we hear most often.
What moisture is best for compost pelletizing?
→
The sweet spot depends on your material, but most compost mixes run best when they are crumbly, not paste-like. In daily production, we often see good results around 15–25% moisture before pelletizing, then drying to 12–15% for storage. Too wet causes blocking; too dry makes weak pellets. Always test your own mix.
Do I need a binder?
→
Usually no. Compost contains natural fibers, starches, and microbial gums that bind under pressure. Our ring-die compost pellet machine uses mechanical pressure, not chemical binders. If your material is very dry or sandy, a small amount of water, molasses, or clay may help.
What capacity can you supply?
→
We build compost pellet machines from about 1 t/h to 26 t/h, and larger lines by combining units. The right size depends on your raw material, moisture, pellet diameter, and working hours. For a farm-scale project, 1–3 t/h is common; industrial sludge or fertilizer plants often choose 5–20 t/h.
How long does the ring die last?
→
Die life varies with material abrasiveness, moisture, and maintenance. On clean, well-ground compost, an alloy-steel die can last hundreds of hours; with sludge, sand, or green waste, it wears faster. We recommend regular inspection, correct roller gap, and removing stones or metal before the die.
Can you supply a complete turnkey compost pellet plant?
→
Yes. We provide more than one compost pellet machine: fermentation turners, crushers, mixers, pellet machines, dryers, coolers, screens, conveyors, and packing scales. From layout design to installation and operator training, we support the whole project. Tell us your site and target, and we’ll build the line around it.
We mainly pellet chicken manure blended with straw. What grinding fineness and moisture range help keep the ring die from clogging?
→
In our experience, straw must be ground to 2–5 mm before blending with chicken manure. If it’s longer, the die can bridge and clog. Moisture is the bigger culprit: aim for a crumbly mix, usually 15–20% before pelletizing. Too wet, and the die slips; too dry, and pellets crack.
Bagasse from our sugar mill is very fibrous. What pellet output and power draw should we realistically expect?
→
High-fiber bagasse will lower output compared with manure-based compost—expect a moderate drop, maybe 20–30%. Power draw rises because the fiber is tough and abrasive. On-site tests show pre-grinding to 3–5 mm and consistent moisture are essential. A heavy-duty alloy-steel die and a larger motor help offset wear. Realistic output depends on die size and line setup.
Our recipe changes often—manure, crop residues, food waste, and additives. How much adjustment is needed between different raw material batches?
→
Formula changes are normal in compost plants. The main adjustments are roller-die gap, feeder speed, and sometimes die compression ratio. With a hydraulic system and variable-frequency feeder, operators can switch between mixes without a full rebuild.Keeping a simple trial log helps you find the right settings faster for each new recipe.
If we add NPK, minerals, or microbial agents into the compost, do we need to change the die compression ratio or feeder speed?
→
Usually not the die compression ratio—but feeder speed and mixing time often need tweaking. NPK and minerals can make the mix denser or more abrasive, while microbial agents are heat-sensitive. Room-temperature pelletizing protects them. Please conduct small-batch testing before full-scale production.
We run dry compost one week and wet fermented material the next. Can one compost pellet machine handle both?
→
Yes, but you’ll need to adjust moisture and feeder settings between batches. Dry compost may need a little water or steam to reach the right crumbly state. Wet fermented material often needs blending with dry returns or a short pre-dry. Our variable-frequency feeder and adjustable roller-die gap let you switch without changing the whole machine.
Still unsure? Send us your raw material, target output, and local power condition. We’ll reply within 24 hours—and recommend the right compost pellet machine plus a complete, matching production line solution.
