Name: China Screw Press Dewatering Machine For Pig Manure And Cow Dung Manufacturers Suppliers - Mingjia Environmental
Brand: Mingjia
SKU: 305047536

Mingjia's drum screen solid-liquid separator is designed for high-moisture, low-solid liquid waste such as livestock manure and biogas slurry. Made of stainless steel with a nylon screen mesh, it offers excellent corrosion resistance. With large handling capacity and over 90% solid removal rate, it significantly reduces downstream treatment load. The screen size is customizable, making it suitable for rising manure, water-submerged manure, biogas slurry filtration, and other application

Workflow Diagram

product-752-508

1.Feeding – Slurry enters the rotating cylindrical screen through the inlet pipe.

2.Solid-Liquid Separation – Centrifugal force from rotation, combined with gravity, forces liquid through the screen openings. Solids larger than the openings adhere to the inner wall.

3.Liquid Outlet – The separated liquid drains to the bottom outlet for collection or further treatment.

4.Solid Discharge – Retained solids move axially along the rotating screen toward the discharge end and exit the cylinder.

Machine Features

1.Cylindrical Screen Assembly – The key component is a stainless steel wire mesh cylinder, chosen for its corrosion resistance against organic acids and ammonia. The mesh has precise hole sizes, and the cylinder diameter is customizable for different throughputs.

2.Drive Mechanism – An electric motor drives the separator, with power rated appropriately for the equipment's size and expected load, ensuring steady performance.

3.Inlet & Outlet Systems – The inlet pipe brings manure slurry into the rotating screen. Liquid passes through the mesh and is collected below, then sent to storage or further treatment. Solids that stick to the inner screen are compressed and ejected from the end of the cylinder.

Key Advantages

1.High-Efficiency Separation – The cylindrical screen achieves separation efficiency over 90%, reducing waste volume and concentrating recoverable nutrients.

2.Cost-Effectiveness – Low cost due to simple design and low energy requirements. The recovered solids and liquids have economic value, offsetting operation costs.

3,Easy Operation & Maintenance – Simple to operate with minimal intervention. Maintenance is straightforward; screen can be easily cleaned or replaced; standard spare parts are available.

4.Environmentally Friendly – Composting solids avoids landfill. Treated liquid can be safely reused or discharged. Nutrient recovery reduces synthetic fertilizer use and associated pollution.

application

01.

Cattle Farms

Large cattle farms produce massive daily manure. The drum screen separator isolates solid manure from liquid waste. Solids become compost for fields; treated liquid serves as nutrient-rich irrigation, cutting synthetic fertilizer use.

02.

Poultry Farms

Poultry manure is rich in key nutrients. This separator processes it well. Solids are used for high-quality horticultural compost. Treated liquid can be recirculated for cleaning or used in hydroponics.

03.

Small-Scale Community Sewage Systems

In small rural sewage plants, the separator pre-treats by removing large solids (wipes, debris). This protects downstream pumps and biological tanks from clogging.

04.

Combined Sewer Overflow Management

During heavy rain, overflow from combined sewers is separated into solids and liquids. Solids are safely disposed; liquids are treated to environmental standards, reducing water pollution.
