Production line and factory setup overview
A micro/workshop finishing line receiving fully matured compost and converting it into a consistent bagged soil amendment through quarantine inspection, removal of plastics and metal, controlled feeding, enclosed trommel screening, oversize and contaminant separation, optional recipe blending only after agronomic approval, surge storage, gross weighing into open-mouth 10-25 kg bags, stitching or heat sealing, coding, check weighing and retained-sample release. Active composting and waste sanitation are outside this line.
Recommended lowest-entry line configuration Accept only fully stabilized compost with a documented source. Start with one screened unblended soil-amendment grade, a small covered feed hopper, magnet/manual picking, enclosed 1-2 t/h trommel with dust control, oversize return bin, surge hopper, semi-automatic gross weigher for 10-25 kg open-mouth bags, stitcher, coder and check scale. Do not bag hot, odorous or pathogen-unsafe material.
Production process and implementation sequence
- Mature-compost quarantine and sampling
- Plastic/metal removal
- Controlled trommel screening
- Oversize separation and return
- Optional approved blending
- Surge storage and gross weighing
- Bag stitching/sealing and coding
- Check weight, retained sample and release
Products, capacity and market fit
- Screened bagged compost can serve nurseries, farms and urban gardening.
- A finishing line is much cheaper than a complete municipal composting plant.
- One unblended grade reduces formulation and labeling risk.
- Maturity, pathogens, weed seeds, salts, plastics and bag weight determine buyer trust.
- Screened bagged compost soil amendment - Declared feed source, screen size, maturity, moisture, pH, EC, organic matter, contaminants, pathogens and net mass - Nurseries, farms, landscaping and household gardening
