Screw Press Livestock Sludge Dewatering Machine is designed for livestock sludge dewatering. It adopts advanced screw pressing technology to efficiently separate water and solids in sludge, and achieve sludge reduction and harmless treatment. The equipment has a compact structure, easy operation, low maintenance cost, and can significantly improve sludge treatment efficiency and reduce treatment costs. The unique dewatering process ensures that the moisture content of the sludge after dehydration is low, which is convenient for subsequent transportation and disposal, and effectively reduces environmental pollution. It is suitable for all kinds of livestock farms and is an environmentally friendly and efficient sludge treatment.
The main body of the spiral screw machine is composed of stationary rings and movable rings stacked into a cylindrical shape, with a spiral shaft running through it to form a filtering device. Because the inner diameter of the movable ring is smaller than the outer diameter of the spiral shaft, the rotation of the spiral shaft can drive the movable ring to perform circular motion, preventing blockages. The gap between the stationary ring and the movable ring gradually narrows along the direction of the mud cake outlet, from the thickening to the dewatering section. After the sludge is thickened by gravity in the thickening section, it is gradually transported to the dewatering section, where forced dewatering is achieved under the internal pressure generated by the back pressure plate at the discharge outlet.
Advantages of the spiral screw:
1. Proficient in handling oily sludge: Compared to traditional sludge dewatering machines, the self-cleaning structure of the spiral screw is less likely to cause filter gap blockages, and it can easily handle oily sludge.
2. Compact design, space-saving: Compared to traditional sludge dewatering machines, the dewatering body, flocculation mixing tank, and electrical control cabinet of the spiral screw sludge dewatering machine adopts a three-in-one design, which is convenient for installation, occupies a small volume, and is highly compatible with ancillary supporting equipment, facilitating the replacement of existing equipment.
3. Simple operation and maintenance: It can be fully automatic and unattended for 24 hours through various sensing devices, and at the same time, there are few daily maintenance items, and maintenance work is simple.
4. Energy-saving: As the core component of the spiral screw, the rotation speed of the spiral shaft is 0-5 revolutions per minute. Due to the low-speed rotation, the electricity consumption is deficient. Under the same treatment capacity, the electricity consumption of the spiral screw is only 1/20 of that of the centrifugal dewatering machine.
5. Water-saving: The self-cleaning structure of the spiral screw body that prevents filter gap blockage can save a large amount of water for cleaning. Under the same treatment capacity, the water consumption of the spiral screw is only 1/115 of that of the belt dewatering machine.
6. Wide application range: Suitable for various industries such as municipal, tap water, pharmaceuticals, food, beverages, animal husbandry, chemical, machinery manufacturing, metal processing, petrochemical, and printing and dyeing.
7. Low noise, low vibration: The spiral shaft of the spiral screw body rotates at low speed, with almost no noise and vibration, ensuring a comfortable and quiet working environment.

The screw press livestock sludge dewatering machine is a robust and efficient solution designed for continuous solid-liquid separation of manure and organic wastewater from livestock farms. It effectively reduces sludge volume, decreases transportation costs, and facilitates subsequent resource utilization of the dewatered solids as organic fertilizer or bedding material. The system operates on a simple yet effective principle, using a screw auger to compress the sludge and separate the liquid phase through a cylindrical screen, ensuring a high dewatering rate and stable performance.
This product is specifically engineered for solid-liquid separation in the following industrial and agricultural sectors:
Compared to belt filter presses, our screw press dewatering machine offers a simpler and more compact design, resulting in a significantly smaller footprint and lower maintenance requirements. The fully enclosed system minimizes odor and noise, which is a major concern for many farm operations. Furthermore, the screw press is less sensitive to variations in sludge consistency, providing stable performance without the need for additional polymer dosing in many cases. Its continuous, low-speed operation reduces energy consumption and wear on components. Our technical team can provide a detailed comparison and recommend the optimal solution based on your specific sludge characteristics and operational goals.
The final dry matter content of the dewatered solids typically ranges from 25% to 35%, depending on the initial consistency of the incoming sludge and the presence of any fibrous materials. This level of dewatering is highly beneficial for downstream applications. It significantly reduces the volume and weight of the solid waste, decreasing transportation costs to composting or drying facilities. For composting, a higher dry matter content accelerates the aerobic process, as it provides a better carbon-to-nitrogen ratio and improved porosity for aeration, leading to a faster and more efficient composting cycle. We recommend conducting a pre-purchase pilot test with your specific sludge to determine the exact dewatering efficiency and optimize the process parameters.
