The Eriez HydroFlow line of centrifuge filter systems feature an open rotor bowl fitted with a long-life, removable flexible liner. These systems are often combined with high capacity cartridge filters to polish dirty fluid and remove fines down to fiveµm.
The Eriez HydroFlow centrifuge product line offers many combinations of centrifuge models, tank sizes and pump pressures used with the high performance model HP-20 single bowl or model HP-40 double bowl.
These centrifuge filter systems are applicable for tool and cutter grinding, glass and ceramic grinding, filtering honing and micro finishing oil, vibratory finishing, wire drawing and all types of carbide grinding. Besides removing fines down to fiveµm, these filter systems offer quick and easy sludge recovery, re-usable sludge collection liners, low operating cost and come in a compact size with low inlet height.
Eriez HydroFlow centrifuge filter systems operate on a basic principle: An open rotor bowl is driven at high speed. Into this is fitted a long-life removable flexible rotor liner shaped to the inner contour of the rotor. The rotor liner is secured by a removable vane assembly.
Dirty coolant enters at the top of the rotor assembly and is deflected by the center cone toward the base of the bowl. Centrifugal force acts on the dirty coolant, packing the foreign matter into a "cake" against the wall of the rotor liner. The cleaned coolant or oil overflows into the clean tank and is returned to the machine tool by a separate pump.
Environmentally friendly reusable liners offer clean, fast disposal or recovery of the sludge cake extracted from the coolant. Cleaning takes only a few minutes and its frequency depends largely on the stock removal rate. These liners have 250 cubic inch (6350mm) of solids capacity or will collect approximately 20/50 lbs. sludge cake.
These efficient centrifuge systems have no consumable cost, no disposal of spent media and no stocking of medial roll. They also employ a safety feature, including a gas shock on the cover and a timer operated lid lock to prevent opening during operation.
Related Glossary Terms
- centrifuge
centrifuge
Filtering device that uses a spinning bowl and the differences in specific gravities of materials to separate one from another. A centrifuge can be used to separate loosely emulsified and free oils from water-diluted metalworking fluid mixes and to remove metalworking fluids from chips.
- 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.
- grinding
grinding
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
- recovery
recovery
Reduction or removal of workhardening effects, without motion of large-angle grain boundaries.
