In the manure treatment process of livestock farms, solid-liquid separation is a critical step. Choosing the right separator not only reduces the load on downstream fermentation or wastewater systems but also converts solids into valuable organic fertilizer or bedding material. This guide combines Mingjia Eco's product features to help you make the right choice.
Three Core Questions Before Selection
Before selecting a separator, answer these three questions:
What material are you processing? – Pig manure, chicken manure, cow dung, biogas slurry, or flushed manure? Moisture content, fiber content, and particle size vary significantly.
How much volume per day? – Farm scale determines manure output, which must match equipment capacity.
What will the separated solids be used for? – Organic fertilizer, bedding, or direct transport? Different uses have different moisture requirements.
Mingjia Product Line Overview
Mingjia Eco offers four types of solid-liquid separators for different scenarios:
I. Cylindrical Screen Separator – Large Capacity, Fine Separation
Designed for high-moisture, low-solid-content liquids like flushed manure, soaked manure, and biogas slurry. Features stainless steel body, nylon screen, and strong corrosion resistance. Processing capacity: 20-40 m³/h with customizable screen mesh (60-40-20 mesh/inch). Solid removal rate exceeds 90%. Ideal for large farms using water-flush cleaning systems and biogas slurry filtration.
II. Screw Press Separator – Compact, Ideal for Small to Medium Farms
Uses a screw shaft to squeeze moisture out of manure, producing solids with low moisture content for easy packaging and transport. The new model has a built-in motor at the bottom, saving space and preventing water damage. Small farms can feed material directly without a pump, reducing sedimentation tank size. Processing capacity: 10-20 m³/h.
III. Inclined Screen Separator – Small Scale, Specialized for Poultry
Specifically designed for chicken and duck manure, soaked manure, and biogas sludge. Combines gravity separation and screw pressing. Features stainless steel construction, reinforced screw shaft with tungsten carbide wear protection, and advanced wedge-shaped screen design for extended service life.
IV. Cow Dung Specialized Separator – Coarse Fiber, Large Volume
Developed specifically for dairy farms to handle large volumes of coarse-fiber cow manure. Effectively solves the rapid wear and low efficiency problems of traditional separators. Produces solids with 50-60% moisture content, suitable for direct use as cow bedding after simple treatment. Ideal for large dairy farms in dry areas.
Quick Selection Reference
| Farm Type | Recommended Model | Capacity | Key Advantage |
|---|---|---|---|
| Large pig farm (flushed) | Cylindrical Screen | 20-40 m³/h | Large capacity, fine separation |
| Small/medium pig farm | Screw Press | 10-20 m³/h | Compact, direct feeding |
| Chicken/duck farm | Inclined Screen | 20-40 m³/h | Poultry-specific, wear-resistant |
| Large dairy farm | Cow Dung Specialized | Customized | Coarse fiber, bedding reuse |
Common Selection Mistakes
Price over performance: Cheap units often have poor separation and high solids moisture, increasing downstream costs.
Ignoring material traits: Using pig manure equipment for cow manure causes rapid wear.
Capacity mismatch: Undersized units cause manure buildup; oversized units waste investment.
Overlooking maintenance: Low purchase costs may come with frequent part replacements, raising long-term expenses.
Summary
The key is to match equipment to your specific material, farm type, processing scale, and end-use. Mingjia Eco offers a full range of solid-liquid separation solutions for diverse farming needs. For detailed specifications or customized solutions, please contact us.
