compact manure screw press separator for pig slurry
Product Overview The Compact Manure Screw Press Separator processes pumpable livestock slurry into a separated solid fraction and a liquid fraction. It combines a rotating press screw with a screening section in a space-conscious assembly. For commercial pig farms, it can be installed beside manure storage or within a dedicated processing area serving steel structure pig houses. The separated streams can then be directed to their respective storage, transport or treatment systems.
Key Features
  • Compact arrangement suits farm sites with limited processing space.
  • Screw and screen separate suspended solids from liquid manure in one continuous process.
  • Stainless steel wetted components can be specified for manure exposure and routine cleaning.
  • Screen opening and discharge resistance can be selected for the required separation duty.
  • Separate liquid and solids outlets simplify connection to storage pipes, chutes or collection containers.
Structural Components A typical unit includes a slurry inlet, screen basket, rotating press screw, gearmotor, shaft sealing arrangement, liquid collection outlet, solids discharge and support frame. The outlet compression mechanism and inspection access depend on the selected configuration.
Working Principle A feed pump delivers mixed, pumpable manure to the screening section. Liquid passes through the screen and drains to a collection line. The rotating screw carries retained solids toward the outlet, where compression expels additional liquid before the solids discharge. Throughput and solids dryness vary with slurry composition, screen selection and outlet setting.
Technical Specifications
  • Feed capacity: According to project requirements and manure characteristics.
  • Screen opening and screen material: Customizable.
  • Motor power and electrical supply: Available upon request.
  • Expected solids dryness: Determined by feed composition and operating settings.
  • Inlet, liquid outlet and solids discharge: Matched to the project layout.
Applications Suitable for selected pig slurry separation duties, livestock manure pretreatment and digestate processing where the feed remains pumpable. The solid fraction can be collected for further handling, while the liquid fraction can be routed to storage or subsequent treatment according to the farm's nutrient management plan.
Customization Options The screen, screw wear materials, motor supply, frame, outlet arrangement and controls can be reviewed against the slurry and site requirements. Feed pumps, inlet tanks, elevated platforms and solids collection equipment can be coordinated for new pig farm construction or an existing manure treatment area.
Installation & Maintenance Mount the separator on a stable, level support with sufficient access to the drive, screen and solids outlet. Provide a controlled feed supply, free drainage for the separated liquid and clear space below the solids discharge. Inspect the screen for blockage, check screw and seal wear, and clean the unit according to the supplied instructions. Isolate the electrical supply and feed line before maintenance.
Product FAQ

Can the separator process pig manure?
Yes, when the slurry is pumpable and the screen and operating settings are selected for its solids content and composition.

Is a feed pump required?
A feed pump is commonly used to supply slurry from a collection pit or tank. Its selection depends on the installation layout.

What determines the dryness of the separated solids?
Feed composition, screen opening, screw operation and outlet resistance all affect the result. A representative slurry sample helps establish realistic targets.
