Heavy-Duty Screw Press Manure Separator: High-Efficiency Dewatering for Cattle & Pig Dung

In industrial cattle ranches, dairy farms, and pig breeding facilities, handling liquid manure slurry is a major operational headache. Raw slurry is heavy to transport, smells intensely, and cannot be directly composted or converted into fertilizer pellets without reducing water content.

A heavy-duty screw press manure separator is the ultimate front-end machine for livestock waste treatment, mechanically separating raw slurry into dry solid fiber and clarified liquid in seconds.

Key Technological Advantages of Our Screw Press Separator

Designed specifically for abrasive, high-fiber animal dung, our dewatering machines deliver unmatched separation efficiency:

1. High-Torque Continuous Screw Extrusion

A submerged slurry pump feeds raw manure slurry into the inlet. A heavy-duty internal screw auger made of hardened alloy steel forces the material forward against a counter-pressure discharge valve. Mechanical squeezing forces liquid out through the cylindrical wedge wire screen while pushing dry solid cake out the front.

2. Corrosion-Resistant SUS304 Stainless Steel Wedge Screen

The internal cylindrical screen features precision laser-cut continuous slots ($0.5\text{mm}–1.0\text{mm}$). Constructed from SUS304 stainless steel, it resists chemical corrosion from animal urine and abrasive sand particles found in cattle bedding.

3. Adjustable Discharge Moisture ($40\%–60\%$)

By adjusting the weight counterbalances on the discharge door, operators can fine-tune the dryness of the output solids. The resulting dry cake is light, virtually odorless, and can be immediately stacked for aerobic composting or used as recycled cow bedding (solids recovery).

Dewatering Machine Specification Matrix

Choose the appropriate separator capacity based on your farm head count:

Model	Drive Power (kW)	Processing Capacity (Slurry m3/hr)	Output Solid Moisture	Ideal Application
FL-200	4.0 – 5.5 kW	$8.0 – 15.0\text{ m}^3 / \text{h}$	$45\% – 60\%$	Medium pig farms (~2,000 head), small dairies
FL-280	5.5 – 7.5 kW	$15.0 – 25.0\text{ m}^3 / \text{h}$	$40\% – 55\%$	Large dairy ranches (~1,000 cows), swine plants
FL-350 Heavy	11.0 – 15.0 kW	$30.0 – 50.0\text{ m}^3 / \text{h}$	$40\% – 50\%$	Centralized livestock waste treatment centers

Heavy Industrial Construction & Reliability

1. Hardened Alloy Screw Blades: Auger flighting is hard-faced with tungsten carbide wear-resistant alloy coatings, extending service life by $3\times$ when processing sand-laden cow manure.

2. Clogging-Free Self-Cleaning Design: The continuous high-pressure squeezing action prevents fiber buildup along the screen surface, ensuring uninterrupted continuous operation.

3. Energy Efficient Operation: Consuming under 7.5 kW for standard models, our separators deliver low operational costs ($/\text{ton}$ of processed waste).

Frequently Asked Questions (FAQ)

Q: Can separated solid cattle manure be reused directly as dairy cow bedding?

A: Yes! Dewatered solids with $40\%–50\%$ moisture can be aerobically fermented in a drum for 24–48 hours to kill pathogens, creating clean, soft, cost-effective recycled solids bedding (RMS) for dairy stalls.

Q: How often does the stainless steel screen mesh need cleaning?

A: The continuous wipe action of the screw keeps the screen clean during operation. For routine maintenance, a quick flush with a high-pressure water gun once a week is sufficient.
