Manure to Fertilizer Machine

A farm-scale powder line begins with a solid liquid separator, a compost turner, a crusher, a screener and a packing scale, and is the lowest-investment way to sell organic fertilizer. A complete granule line costs substantially more because granulation, drying, cooling, coating, conveying and dust removal are added. Price is driven by daily manure volume, moisture, the fertilizer form and the automation level. Send us your animal type, daily manure tonnage and target product and we will return a full equipment list with a budget range.

Fermentation is the longest stage. Aerobic windrow composting of cattle or horse manure takes 10–15 days with turning every two to three days; poultry and pig manure blended with a carbon source matures in 7–12 days, and in-vessel fermentation tanks shorten it further with forced aeration and temperature control. Everything after composting — crushing, screening, mixing, granulating, drying and packing — is continuous and completes within hours.

You can dry and bag fresh manure, but it is a poor product: it still carries weed seeds, pathogens and a high ammonia and salt load, it smells, and it can burn crops. Composting is what converts manure into a stable organic fertilizer, destroys pathogens above 55 °C, and concentrates the organic matter. Every serious commercial operation ferments first, and most certification schemes require it.

Poultry manure has the highest nitrogen, phosphorus and calcium content and sells at the highest nutrient analysis, but it needs drying and deodorising before it can be handled. Cow dung produces the largest volume of high-quality humus and composts most easily, which is why it dominates organic fertilizer production worldwide. Horse manure mixed with bedding composts well for the landscaping and nursery market, and goat manure is the simplest small-scale material because it dries and composts quickly.

Only if you granulate. Compost leaves fermentation at 55–65% moisture, and disc or drum granulation needs roughly 25–35%, so wet granules must be dried to 12–14% in a rotary dryer and then cooled. A powder fertilizer line needs no dryer at all — the compost is air-dried, crushed, screened and bagged, which is why powder lines are so much cheaper to build and to run.

A 5 t/h granule line running eight hours a day produces about 40 tonnes of finished fertilizer per shift. Because composting reduces volume by 30–40%, the plant consumes roughly 55–65 tonnes of raw manure per day, which is the output of about 300–400 head of cattle, or 60,000–90,000 laying hens depending on the housing system.

Yes. Every project is supplied with a factory layout drawing, equipment foundation drawings and an electrical and piping schematic. A YUSHUNXIN engineer attends the site for installation and commissioning, trains your operators on start-up, normal running, maintenance and fault finding, and our service team supports the plant remotely for the life of the equipment.

Five things: (1) the animal and the manure type, including whether it is fresh slurry or dried; (2) the daily manure volume or head count; (3) the fertilizer you want to sell — compost, powder or granules, organic or organic-inorganic; (4) your country and site conditions, including climate and available power; and (5) your automation and budget expectations. With those five answers we can propose a process route and an equipment list the same week.
