What counts as a small plant
Renyuan treats lines up to about 10,000 t/yr as small plants. A 10,000 t/yr line runs at about 1.5–2.5 t/h. At this scale a medium or basic configuration does the job, and equipment can be added later when you expand.
Starting with a powder line (3,000–5,000 t/yr)
The simplest commercial plant composts the raw material and sells it as powder fertilizer. Conveyors connect each machine.
- Pile the raw material and adjust its moisture.
- Add a composting inoculant.
- Turn the piles with a compost turner and compost for 12–15 days.
- Crush the composted material.
- Screen it.
- Pack the finished powder.
Equipment, composting recipe and daily output change with the raw material. Discuss your feedstock before fixing the layout.
A reference 10,000 t/yr granular configuration
Renyuan's published 10,000 t/yr layout uses the following equipment. It shows the scale of each machine; your configuration is set from your material and site.
| Stage | Reference equipment |
|---|---|
| Composting | 3 m or 4 m trough turner, 7.5–11 kW; one turner can serve several troughs |
| Crushing | Semi-wet material crusher (600 size), 21 kW, 3–5 t/h |
| Mixing | Horizontal mixer (900 size), 7.5 kW |
| Granulation | Disc granulator, 3,000 mm, 11 kW |
| Drying | 12 m rotary dryer, 11 kW; inlet moisture about 50%, outlet about 15%; 3–5 t/h |
| Cooling | 10 m rotary cooler with natural air, 7.5 kW, 3–5 t/h |
| Coating | 1.2 × 4 m coating drum, 5.5 kW, 8 r/min |
| Screening | One screen after crushing to grade the raw material, and one after cooling for the finished product |
| Packing | Automatic weighing and bag sewing, 3–6 bags per minute |
Three configuration levels
| Level | Equipment |
|---|---|
| High | Manure dewatering machine, compost turner, semi-wet crusher, horizontal mixer, granulator, dryer, cooler, trommel screen, coating machine, packer, belt conveyors |
| Medium | Semi-wet crusher, horizontal mixer, granulator, dryer, cooler, trommel screen, packer, belt conveyors |
| Basic | Semi-wet crusher, horizontal mixer, granulator or trommel screen, packer |
Phase the investment
If capital is limited, start with a line without the granulation system. Run it for a while, then add granulation once you know your market. This lowers the risk of the initial investment.
Before buying, compare manufacturers of real scale, visit the factory if you can, and ask to see equipment running. Renyuan welcomes buyers to its factory in Hebi, Henan.
Renyuan equipment for this line
- Powder Organic Fertilizer Production Line
Turn composted organic material into a powder product through crushing, screening, premixing and bagging. The line starts with the feedstock and finished-product requirements.
- RY-ZFP Standard Trough Compost Turner
The standard RY-ZFP series turns and mixes organic material in fixed composting troughs. The 40/50 and A/B combinations have different widths, working depths and main motor ratings, so selection begins with the trough geometry.
- RY-LFD Series Crawler Compost Turner
RY-LFD crawler turners mix and aerate composting windrows across several working widths. Start with windrow width, then check site access and the turning requirements of the selected model.
- Integrated Hopper and Crusher
Combines hopper loading, conveying and crushing for organic-material preparation.
- RY-GS Trommel Screen
The trommel screen grades fertilizer material through a rotating screen. Use it after crushing for powder processing or in granule finishing, with apertures and recycle routes matched to the finished-product size.
- Disc Granulator
Forms fertilizer granules in a rotating disc and connects with mixing and downstream finishing stages.
- Single-Hopper Belt-Fed Automatic Weighing and Packing Machine
A belt-fed single-hopper packer for mixed or irregular materials, listed at 200–300 bags per hour.
Frequently asked questions
What equipment does a small organic fertilizer plant need?
At minimum: a compost turner, a crusher, a screen and a packer for powder fertilizer. Add a mixer, granulator, dryer and cooler for granules.
What hourly capacity is a 10,000 t/yr line?
About 1.5–2.5 t/h.
Can I add granulation later?
Yes. Many small plants start with powder fertilizer and add the granulation system once the market is established.
