Product Features

Efficient Separation Design: The optimized ratio of drum length to diameter and the angle of the spiral blades ensure a uniform distribution of centrifugal force field, enabling rapid solid-liquid separation. The solid phase has a low water content, and the liquid phase is highly clear.
Corrosion-resistant and Wear-resistant Materials: The contact material components are made of duplex stainless steel or super austenitic stainless steel, which have strong resistance to chloride ion corrosion and are suitable for processing high-salt and strong acid-base materials.
Flexible Differential Speed Adjustment: The planetary gear differential can precisely adjust the speed difference, adapting to the separation requirements of different materials and ensuring stable sludge transportation without clogging.
Automation and Intelligence: The PLC control system can monitor parameters such as speed, torque, temperature, and pressure in real time, support remote control and fault alarm, and reduce manual intervention.
Stable Operation Structure: The use of shock-absorbing base and dynamic balance design results in low operating noise (≤85dB), small vibration, and extended equipment lifespan.
Easy Maintenance Design: Key components (such as spiral blades and differential gear) can be quickly disassembled and replaced, and the sealing components adopt modular design to reduce maintenance costs and downtime.

Core Advantages

High separation efficiency: Compared to traditional centrifuges, it has a larger processing capacity and better separation results. The solid phase moisture content can be reduced to 75%-85% (depending on the material), and the liquid phase suspended matter content (SS) is ≤ 100mg/L.
Low operating cost: With high automation, it reduces labor costs; energy consumption is 10%-15% lower than similar equipment; corrosion-resistant materials extend equipment lifespan and reduce replacement and maintenance frequencies.
Strong adaptability: It can handle various materials, ranging from low-concentration sludge to high-viscosity chemical slurries. By adjusting parameters, it can adapt to different working conditions without the need for large-scale renovations.
Environmentally friendly and safe: The fully enclosed structure eliminates dust leakage, reducing secondary pollution; equipped with safety devices such as overload protection, over-temperature protection, and imbalance protection to ensure operational safety.
Brand and service: TOMOE, as a well-known centrifuge manufacturer in Japan, has over 70 years of industry experience. It has a global service network and provides professional technical support and after-sales maintenance.

Typical Application Fields

Environmental Protection Field
Municipal Sludge Dewatering: Treating the residual sludge from urban sewage treatment plants, reducing the moisture content from around 98% to below 80%, and reducing the volume by 90%, making it easier for subsequent landfill or incineration.
Industrial Wastewater Treatment: Solid-liquid separation for wastewater from industries such as dyeing, papermaking, and electroplating, removing suspended solids and heavy metal sludge.
Chemical Engineering and Mining
Fine Chemicals: Mother liquor recovery and solid-phase purification in resin, pigment, and dye production.
Mining: Dewatering of tailings slurry, solid-liquid separation in mineral processing, such as kaolin, calcium carbonate, etc.
Food and Pharmaceuticals
Food Processing: Juice clarification, starch dehydration, dairy product separation, plant protein extraction, etc. For example, removing the skins and seeds in the production of tomato sauce.
Pharmaceutical Industry: Solid-liquid separation of antibiotic fermentation liquid, clarification of traditional Chinese medicine extract solution, in accordance with GMP standards.
Other fields
Petrochemical industry: Treatment of oily sludge, separation of crude oil and sludge, and resource recovery.
New energy: In the production of lithium battery materials, solid-liquid separation of positive electrode materials (such as lithium iron phosphate) to ensure product purity.
