In the mineral cutting processing stage of a major machine tool manufacturing company, mineral sludge adhered to mineral oil and floated in an 800L coolant tank. Over time, it absorbed moisture and settled, leading to the proliferation of bacteria and causing decay. Additionally, although the cutting oil was still usable, it was completely discarded within five months due to the presence of mineral oil and mineral sludge. As a result of a practical test using the oil-water separation device "LSSII-ECO Standard Unit," mineral oil and mineral sludge mixed with the cutting oil were separated and recovered. After implementation, the cutting oil was not discarded for eight years, achieving a 16-fold increase in longevity, and long-life tests are still being conducted.

At the aircraft parts machining factory, machining is performed by cutting parts from aluminum blocks, and aluminum microparticles (μ) with little specific gravity difference from the cutting oil are floating up, adhering to the mineral oil as sludge. Additionally, there is a high possibility of causing defects in the product accuracy of the machined parts, and it can also lead to foul odors, which is why the entire cutting oil is discarded four times a year. As a result of conducting a practical test using the oil-water separation device "LSSII-ECO Standard Unit," sludge containing aluminum microparticles mixed in the cutting oil was separated and recovered from the mineral oil. Since its introduction, we have achieved a long life of 24 times without discarding the cutting oil for six years, and we are continuing tests for further long life.

At an automotive parts processing company, chemical treatment is conducted at a high temperature of 190°C during the gear hardening process. Using a filter press machine, black fine sludge particles under 100μ are recovered from the chemical liquid, but the nightly tasks of attaching and detaching the filter and cleaning it are labor-intensive and costly. As a result of conducting a practical test with the sludge recovery device "M1-250M," the recovery and dewatering time was reduced to one-fourth of the conventional method, while filter cleaning time was reduced to one-fifth, and labor costs were halved, leading to significant cost reductions. 【Overview】 ■ Amount of chemical liquid with sludge contamination: Approximately 120L ■ Classification: Fine black sludge under 100μ ■ Recovery device used: M1-250M standard unit ■ Sludge recovery time: Approximately 10 minutes ■ Sludge dewatering time: Approximately 30 minutes ■ Sludge recovery capacity: Approximately 3.7kg ■ Condition after treatment of chemical liquid: Improved transparency *For more details, please refer to the PDF document or feel free to contact us.

In 2008, a major engine machining company used 6000L (6t) of cutting oil for machining processes and disposed of the entire amount of cutting oil three times a year. Approximately 2t of sludge generated during grinding was mixed into the 6000L of cutting oil, and the dehydration of the sludge during disposal was insufficient, making cost reduction difficult. After introducing four sludge recovery units "M1-250M," the long life of the cutting oil was achieved without replacement for two years. 【Overview】 ■ Test implementation date: December 28, 2008 – for 3 days ■ Location: A major engine machining factory ■ Actual test equipment: M1-250M (MAX 90L/min) x 4 units ■ Amount of cutting oil: Approximately 6000L (6t) ■ Cutting oil used: From a certain cutting oil manufacturer ■ Amount of recovered sludge: Approximately 2.5t *For more details, please refer to the PDF document or feel free to contact us.

At a major engine machining company, approximately 2 tons of metal sludge, including grinding wheels generated during grinding operations, mix with cutting oil, leading to the disposal of 6,000 liters of cutting oil three times a year. Additionally, due to insufficient dewatering of the sludge during disposal, disposal costs were higher than necessary. To solve this problem, a practical test was conducted using the sludge recovery device "M1-250M," resulting in a significant improvement in sludge recovery and ultimately enabling the long life of the cutting oil. 【Overview】 ■ Test date: December 28, 2008, for 3 days ■ Location: Major engine machining factory ■ Test equipment: M1-250M (MAX 90L/min) x 4 units ■ Amount of cutting oil: Approximately 6,000L (6 tons) ■ Cutting oil used: From a certain cutting oil manufacturer ■ Amount of recovered sludge: Approximately 2.5 tons *For more details, please refer to the PDF document or feel free to contact us.

Many users utilize cyclone machines for the recovery of sludge generated during aluminum cutting. While these machines can handle large flow rates, most aluminum, fine powders, grinding (including grinding wheels), carbide polishing, and micro-particles with minimal specific gravity are largely mixed, resulting in a limited amount of recoverable sludge. As a result, the clean tank at the bottom of the cyclone machine, which should collect the cleaned cutting oil, is often not sufficiently cleaned, and a significant amount of sludge remains. To address this issue, we used our sludge recovery device "M1-250M" to recover sludge from the clean tank at the bottom of the cyclone machine. [Overview (Partial)] ■ Implementation Location: Clean tank at the bottom of the cyclone machine (approximately 500L) ■ Sludge Classification: Aluminum ■ Recovery Device: M1-250M (Maximum processing flow rate 80L/min to 90L/min) ■ Recovery Time: 3 minutes x 5 times, totaling approximately 15 minutes *For more details, please refer to the PDF document or feel free to contact us.
