Main structure of liquid solid separator

The main structure of the spiral extrusion solid-liquid separator includes the spiral shaft, screen mesh, extrusion chamber, and other parts. The spiral shaft is a key component of the equipment, and the rotational force and pressure generated during its rotation cause solid particles in the liquid to be separated through the sieve, while the liquid is extruded. The function of a sieve is to control the size of solid particles to meet different separation requirements. The extrusion chamber is used to generate sufficient pressure and rotational force to help achieve better solid-liquid separation effects.

How Does This Machine Actually Separate Manure?

The machine works by using a powerful screw auger to press the wet slurry against a fine screen. The pressure squeezes the liquid out through the screen, while the dry solid material is pushed out at the end.

The technology behind our Solid-Liquid Separator is both simple and extremely effective. It is a type of screw press. The best way to understand it is to imagine wringing out a very wet towel by twisting it. The more you twist, the more water comes out. Our machine does this continuously.

• Feeding the Slurry: A pump moves the raw animal manure slurry from your storage lagoon or pit into the machine’s inlet hopper.
• The Screw Auger: Inside the machine is a long, rotating screw, also called an auger. This auger turns slowly but with a great deal of force. It catches the slurry and begins pushing it forward.
• Pressing and Dewatering: The screw is enclosed inside a durable, cylindrical screen. As the auger pushes the manure forward, the space between the screw and the screen gets smaller and smaller. This builds up immense pressure, squeezing the liquid portion of the slurry out through the tiny holes in the screen.
• Two Separate Exits: The separated liquid is collected in a chamber under the screen and flows out through a pipe. The much drier, fibrous solid material continues to be pushed forward by the screw until it exits the machine at the end, forming a neat, stackable pile.

What Are the Biggest Benefits for Your Farm?

The biggest benefits are turning a costly waste problem into two valuable products, drastically cutting your storage and transport costs, and improving the environmental footprint of your farm.

Integrating a Solid-Liquid Separator into your operation brings immediate and significant advantages. It is an investment that pays for itself quickly.

Turn Waste into Two Valuable Products

This is the most exciting benefit. Your slurry is no longer waste.

• The Dry Solids: The solid material that comes out of the machine has a moisture content of around 30-40%. It is light, crumbly, and has almost no smell. This material is a fantastic raw material for high-quality organic fertilizer. You can put it directly into a windrow and use a compost turner to create a valuable soil amendment that you can sell or use on your own fields. It can also be sold as-is for animal bedding or nursery soil.
• The Nutrient-Rich Liquid: The separated liquid is not just water. It contains a high concentration of nitrogen and phosphorus, making it a potent liquid fertilizer. It can be easily stored and applied to crops through an irrigation system, reducing your need to buy chemical fertilizers. It is also the perfect feedstock for a biogas digester.

Drastically Cut Storage and Transport Costs

Wet slurry is mostly water, making it heavy and bulky.

• Massive Volume Reduction: Our separator can reduce the volume of your solid manure by up to 80%. What was once 10 truckloads of wet slurry becomes just 1 or 2 truckloads of dry, manageable solids.
• Lower Costs: This means you need much smaller and simpler storage facilities. Transporting the solids to a field or to a customer becomes significantly cheaper. Your manure lagoon will fill up much more slowly, extending its life and reducing maintenance costs.

Application examples of screw press manure separator

In the field of livestock and poultry breeding, spiral extrusion solid-liquid separators are mainly used to treat manure from breeding farms. Through this device, the water in feces can be squeezed out to achieve dehydration and drying effects. The processed solid organic fertilizer can be transported to fertilizer deficient areas for use and can also improve soil structure; Liquid organic fertilizer can be directly used for crop utilization and absorption, or further processed into organic compound fertilizer.

Is This Separator Right for YOUR Type of Manure?

Yes, absolutely. Our Solid-Liquid Separator is engineered to be highly versatile. It can effectively dewater slurry from pigs, dairy cows, beef cattle, and chickens.

While the basic principle is the same, we know that manure from different animals has different characteristics. We can fine-tune our machine to give you the best performance for your specific needs.

• Cow Manure: Cow manure has long, fibrous material, which is ideal for separation. Our machine easily handles this and produces a very dry, fluffy solid material perfect for composting.
• Pig Manure: Pig slurry is often very wet and has finer particles. The precision-engineered screen and screw on our separator are designed to handle this high water content effectively, preventing clogging and ensuring a consistent output.
• Chicken Manure: Chicken manure slurry can be thicker and stickier. We adjust the machine’s pressure settings to ensure a smooth flow and prevent blockages, delivering a solid product that’s ready to be processed in your fertilizer granulator.

No matter what kind of livestock operation you run, we have the experience to provide a manure dewatering solution that works perfectly for you. It’s the essential first step in creating a complete fertilizer production line from farm waste.

What are the types of solid-liquid separators

There are various types of solid-liquid separators, including spiral extrusion separators, inclined screen separators, and stacked screw separators, each with their own characteristics and applicable ranges. When choosing, it should be comprehensively considered based on actual needs, wastewater characteristics, and treatment requirements.

Frequently Asked Questions (FAQ)

Question 1: What is the final moisture content of the separated solids?
You can typically expect the final moisture content of the solid material to be between 30% and 40%. This makes it dry enough to stack without an issue and is the perfect starting moisture level for the composting process.

Question 2: How much slurry can the machine process per hour?
We offer several different models with varying capacities to match the size of your farm. Our smaller models can process around 5-10 cubic meters per hour, while our larger industrial units can handle up to 40 cubic meters of slurry per hour.

Question 3: Is it difficult to install and operate?
Not at all. The installation is very straightforward. You just need a solid, level base and connections for the slurry inlet pump and the liquid outlet pipe. Operation is fully automatic. Once you turn it on, it manages itself.

Question 4: What do I do with the separated liquid?
The liquid is a valuable, fast-acting fertilizer. The best way to use it is to store it in a tank or lagoon and then apply it to your fields during the growing season using an irrigation system or a tanker spreader. This greatly reduces your need for commercial fertilizers.

The Solid-Liquid Separator is more than just a piece of equipment; it is a smart business decision for any modern livestock farm. It takes your biggest waste management problem and turns it into a system that generates value, reduces costs, and improves your farm’s sustainability. By separating your manure slurry, you create valuable compost material, produce a free source of liquid fertilizer, and make your entire operation cleaner and more efficient. It is a reliable, durable, and highly effective tool that puts you in control of your farm’s waste stream.
