A new design belt skimmer by Keller Products Inc. eliminates skimmer discard pail overflow and permits virtually 100 percent tramp oil discard with no loss of coolant, while continuously recycling clean coolant to the sump. In contrast to conventional belt skimmers, which attempt unsuccessfully to lift primarily tramp oil, the new “Black Magic”
skimmer directs all the fluid from the belt skimmer to a separation vessel, where the tramp oil is held for discard and the clean coolant returns to the sump, according to the company.
The new belt skimmer is easily mounted on the sump cover with a magnetic mount. The skimmer mounting bracket permits adjusting the height of the skimmer to access the sump. The collected tramp oil may be occasionally drained or poured from the separation vessel into a waste tramp oil container. No other operator attention is required.
Related Glossary Terms
- coolant
coolant
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
- tramp oil
tramp oil
Oil that is present in a metalworking fluid mix that is not from the product concentrate. The usual sources are machine tool lubrication system leaks.
