Workflow Diagram

The separation process is straightforward yet highly effective, built to handle large processing volumes smoothly:
Infeed & Pumping: A heavy-duty submersible delivery pump draws raw slurry or liquid manure from the septic tank straight into the machine's feed port via the inlet pipeline.
Rotary Drum Filtration: The waste enters a high-capacity rotary screen cylinder. Liquid quickly drains through the corrosion-resistant screen mesh, flowing out through dedicated liquid pipelines into a sewage treatment or biogas pond.
Screw Press Dewatering: The remaining solid material is guided into a robust screw press mechanism. This section extrudes residual moisture out of the solids.
Discharge: Thoroughly dewatered solid matter pushes through the final discharge port, dropping out ready for piling, transport, or immediate composting.
Machine Features
Cylindrical Screen Assembly – The screen is a stainless steel wire mesh cylinder, chosen for corrosion resistance against manure's organic acids and ammonia. Uniform holes and customizable diameter suit varying throughput needs.
Drive Mechanism – An electric motor powers the unit, with power rating selected according to machine size and expected load for reliable performance.
Inlet & Outlet Systems – The inlet pipe feeds slurry into the rotating screen. Liquid passes through the mesh and is collected below; solids are pressed and discharged from the cylinder end.
Key Advantages
For project contractors and engineering firms, this setup is a game-changer for site timelines. The machine arrives as a highly integrated unit, featuring an intuitive control box and standard flange connections (DN65 input / DN100–DN150 output) that allow your crew to hook up piping and power without a hitch.
Choosing this Solid Liquid Separator Cow Dung Dewatering Machine Pig Manure Drying Machine Animal Waste Separating Equipment ensures your project benefits from structural longevity and reduced maintenance costs. By stripping the liquid away early, you reduce the footprint needed for subsequent wastewater treatment ponds. The resulting stackable solids can be fed straight into a downstream organic fertilizer fermentation tank, turning a messy compliance headache into a profitable, farm-ready byproduct.
