Eriez’ magnetic coolant cleaners are designed to keep machine tools running longer and more accurately, with lower costs per unit produced. They are suited for use with a variety of equipment, including surface grinders, gear grinders, honing and lapping machines, broaches, milling and drilling machines, face grinders and oil-reclaiming machines.
The cleaners are available in 36 standard models to match users’ requirements for flow rate, viscosity and degree of separation. Nine magnetic roll widths, ranging from 7" to 70" (178 to 1,780 mm), and two types of rolls are available. A smooth-face roll is used for normal conditions, and extended-pole plates are provided for a more-powerful magnetic field that removes micron-sized particles.
The company’s Xtractor rare earth coolant cleaner uses a magnetic circuit design to capture and remove fine ferrous particles from coolant. It is said to be stronger than conventional permanent magnetic separators that use alnico or barium ferrite elements. The rare-earth cleaner is available in four sizes and can handle as much as 30 gpm of water-soluble coolant per foot of drum width (4 lpm per cm of width). It is powered by a TEFC 230/460-V, 60-Hz, three-phase motor.
The rare earth coolant cleaner can be used in virtually any open process to remove fine ferrous contaminant from slurry and can remove grinding swarf to increase machine tool life and accuracy. Applications include the removal of ferrous contaminant from paint-processing lines to ensure the paint does not appear to “rust” once applied. It also can be used in the steel industry to remove moderately magnetic mill scale from rolling mill cooling water.
