Solids-from-Liquid Centrifuges from Eriez HydroFlow provide continuous media-free filtration of both metallic and non-metallic solids from industrial fluids. They are successful in reducing solids in numerous applications where removal of fines is desired, including machining, grinding and sawing, high-speed centrifuge pre-filtration, water jet cutting, de-scaling operations, wire drawing, parts washers, quench tanks, UF pre-filtration and precious metals recovery.
Solids collect in individual machine tool sumps and in large central systems. "It's important to efficiently remove these chips and fines as they have a detrimental effect on coolant performance and longevity as well as causing lost production and headaches during removal," says Ron Wendt, Product Manager-Eriez HydroFlow.
All Eriez' Solids-from-Liquid Centrifuges offer years of trouble-free operation. They are available in both manually cleaned basket style (complete with reusable liner) and fully automatic self-cleaning designs.
Whether mounted on a single machine or used as a component of a complete filtration/recycling system, Solids-from-Liquid Centrifuges reduce or eliminate the use of costly filter paper, bags and cartridges, all of which require proper disposal. They are also used to supplement existing paper media or central systems to remove solids typically missed by barrier filtration. "Eriez' state-of-the-art Solids-from-Liquid Centrifuges are an ideal choice for companies that prefer to remove solids on a continuous basis without the need for disposable media," says Wendt.
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.
- sawing
sawing
Machining operation in which a powered machine, usually equipped with a blade having milled or ground teeth, is used to part material (cutoff) or give it a new shape (contour bandsawing, band machining). Four basic types of sawing operations are: hacksawing (power or manual operation in which the blade moves back and forth through the work, cutting on one of the strokes); cold or circular sawing (a rotating, circular, toothed blade parts the material much as a workshop table saw or radial-arm saw cuts wood); bandsawing (a flexible, toothed blade rides on wheels under tension and is guided through the work); and abrasive sawing (abrasive points attached to a fiber or metal backing part stock, could be considered a grinding operation).
