Introducing the test conducted for sludge recovery in the clean tank under the cyclone unit!
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 stones), cemented carbide polishing, and micro-particles with minimal specific gravity are largely mixed together, 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.
The sludge recovery amount has greatly improved! The long life of cutting oil has become possible.
At a major engine machining company, approximately 2 tons of metal sludge, including grinding wheels generated during grinding processes, 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 use of 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.
We will introduce a practical test where the black, opaque sample showed improved transparency after processing!
At an automotive parts processing company, a process for heat treatment of products involves performing gear hardening at a high temperature of 190°C using chemical agents. Using a filter press machine, black fine sludge particles under 100μ are collected from the chemical liquid, but the filter needs to be removed and cleaned every night, which incurs labor and costs. As a result of a practical test using the sludge recovery device "M1-250M," the collection and dewatering time was reduced to one-fourth of the conventional time, while filter cleaning time was reduced to one-fifth, and labor costs were halved, leading to significant cost savings. [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.
