Can used oil centrifuges separate ash from used motor oil?

Used oil centrifuges of the disc-stack type can remove some of the ash content from used motor oil. Ash particles are microscopic carbon particles, and the centrifuge's separation ability is limited to such tiny particles separation.

Key features

Three-Phase Separation: Simultaneously separates oil, water, and solid particles with high efficiency.

High Separation Efficiency: Removes metal particles down to 0.5 microns and non-metal particles to 2 microns.

Automatic Self-Cleaning: Automatically ejects sludge and discharges water continuously without manual intervention.

Low Operating Cost: No filter media required, eliminating replacement costs and labor expenses.

Compact Footprint: Significantly smaller size compared to traditional filters and settling tanks.

Emulsion Breaking: Breaks oil-water emulsions to recover more oil, though chemical demulsifiers may be needed.

Customizable Voltage: Voltage options available at 380V or 420V to meet specific customer requirements.

Durable Construction: Built with stainless steel 304/316L/Duplex Steel for long-term operation up to 20 years.

AI-Powered supplier vetting

SummaryThe supplier manufactures and sells separation machinery, including decanter, disc, tubular, pusher, basket, and sludge-dewatering centrifuges. It reports R&D, product design, patent, ODM, OEM, and broad customization capabilities, supported by production equipment and stated annual capacities for three centrifuge categories. Quality-related evidence includes ISO9001:2015, ISO45001:2018, ISO14001, CE certification, quality assurance, and raw-material traceability. However, no written procedures or records are available for handling customer complaints, and the corrective/preventive-action process for service capability lacks written records. Financial data is represented only by years, without usable performance values. The supplier states that it has not collaborated with Fortune 500 companies, while its broader customer base includes domestic and overseas users.

Supplier typeThe supplier is a manufacturer and seller of separation machinery and supporting facilities, with stated integration of scientific research, design, manufacturing, sales, and service. Its listed products cover multiple centrifuge and sludge-dewatering categories, indicating an equipment manufacturer rather than a trading-only supplier.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 management-system certifications, together with CE product compliance certification. These explicitly support quality, occupational safety, environmental management, and product-compliance capability.

R&D capabilityThe supplier reports new products within the past year, product design and development capability for LW-series centrifuges, national patents, ODM services, and an integrated research-and-design function. It does not have an available SDK, but that limitation does not directly negate its equipment R&D capability.

Production capacityReported annual productivity is 200 sets for decanter centrifuges, 150 sets for disc centrifuges, and 200 sets for tubular centrifuges. The supplier also lists extensive machining, welding, milling, rolling, CNC, and testing equipment, supporting in-house manufacturing capability.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. These capabilities are reported consistently across the R&D and design-service information.

Product Q&A

Q:Why is a used oil centrifuge a three phase centrifuge?

A used oil centrifuge needs to be a three-phase centrifuge to separate the water and solid particles simultaneously. A two-phase centrifuge will only separate the solids from used oil but not the water.

Q:Is a used oil centrifuge same as a waste oil centrifuge?

A used oil centrifuge is very similar to a waste oil centrifuge. Both are three-phase centrifuges capable of separating oil from water and sludge. A used oil centrifuge may require some modifications to accommodate chemicals such as acids in the process.

Q:Can used oil centrifuges separate emulsified oil?

A used oil centrifuge can separate oil emulsions to a certain extent. Disc stack centrifuges cannot separate chemically bonded emulsions without the use of demulsifiers.

Q:What is the smallest particle a used oil centrifuge can separate?

A used oil centrifuge (disc-stack) can separate metal particles down to 0.5-microns. Non-metal particle separation efficiency is typically around 2-microns.

Q:Do used oil centrifuges use filters or replaceable media?

Disc stack centrifuges for used oil do not use any filters or media. These centrifuges use the amplified force of gravity (centrifugal force) to separate water and sludge from used oil.
