We are a manufacturer of high quality environmental protection equipment in China.
The product adopts the advanced screw extrusion principle, and realizes efficient solid-liquid separation through the rotation of the screw shaft and the gap design of the filter ring. This equipment can not only effectively reduce the water content of the sludge, but also reduce the sludge volume and reduce the treatment cost.
Product Features:
High efficiency and energy saving: Compared with traditional dewatering equipment, our spiral screw sludge dewatering machine has lower energy consumption and lower operating costs.
Automatic operation: The equipment adopts fully automatic control, easy operation and low maintenance cost.
Environmental protection design: No large amount of chemical agents are required during the operation of the equipment, reducing secondary pollution.
Compact design: Suitable for sewage treatment plants with limited space, can be customized to meet different needs.
Our products are widely used in municipal sewage treatment, industrial wastewater treatment, food processing, papermaking, pharmaceutical and other industries
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.

Our eco-friendly spiral screw sludge dewatering machine is an advanced solid-liquid separation solution designed for wastewater treatment plants, food processing industries, and municipal sludge management. This sustainable equipment delivers exceptional performance with minimal environmental impact.
Our spiral screw sludge dewatering machine is perfect for:
1. Superior Dewatering Performance: Our unique spiral design ensures optimal pressure distribution for consistent results across various sludge types.
2. Cost-Effective Solution: Lower operational costs through reduced energy consumption and minimal chemical requirements compared to belt presses or centrifuges.
3. Durable Construction: High-quality stainless steel components resist corrosion and extend equipment lifespan even in harsh environments.
4. Easy Maintenance: Simplified design with accessible components reduces downtime and maintenance expenses.
5. Quiet Operation: Noise levels below 65 dB make it suitable for installation in noise-sensitive areas.
The eco-friendly sludge dewatering machine operates through a gradual dewatering process. Sludge is fed into the machine where it passes through multiple stages of filtration and compression. The rotating screw gradually increases pressure while the screen filters out water, resulting in a dry sludge cake at the discharge end.
Our spiral screw dewatering system contributes to sustainable operations by:
We provide comprehensive support including site evaluation, installation guidance, operator training, and ongoing technical assistance. Our team can help you optimize the sludge dewatering process for your specific application requirements.
Products provided by famous enterprises are deeply trusted by users.
