Our New Vacuum Filtration System

We are about 6 months after second system installation at John Deer Israel. First unit was installed 6 years ago. Each system is a part of a working cell servicing 4 heavy duty centerless grinders. Application is very demanding as grinders utilize very soft wheels to accurately grinding steel parts. The sludge generated is huge and the temperature at the cutting point is very high as well. The challenge was to choose the right solution bearing in mind systems works 24/7. Therefore, we chose to use large magnetic prefilter to partially remove heavy sludge followed by a 20 micron media at a flow rate of 500 lpm to remove residuals.

Then clean coolant accumulates in the clean tank located above the filtration system and slightly overflow back to the dirty tank to keep a continuous filtration. And in the clean tank, we designed and installed a special heat exchanger which use cold water supplied from external source such as air condition chiller. The coolant is kept at 25 +/-2 ºC. A 500 lpm @ 5 bar clean feed pump returns coolant through overhead piping’s to each machine as per request.

Each grinder is suited with a slurry tank to collect and return dirty coolant back to filtration. The system control panel supervise and monitor filtration system, cooling, clean return pump , slurry tanks with all level and pumping facilities and piping valves. These is one of a few system recently installed in Israel. The project was a turn key project we supplied all except the grinders. We feel proud customer is happy with the results and trusted us again.
