Model MSI Magnetic Separator
In the process of rolling steel strip, the roll coolant over time will become contaminated with ferrous particles and tramp oil. These contaminants in high enough concentrations can result in increased roll wear and roll changes, reduced production and product quality, increased roll oil and water consumption and decreased coolant life. The Filtertech Model MSI magnetic separator utilizes a vertical bar design in which a series of magnetic bars form a chain that is driven by a rotating assembly.
The bar chains are arranged in parallel to form a magnetic grid through which the dirty coolant passes. As the dirty coolant passes through the magnetic grid, the ferrous particles are attracted to the magnetic bars and attach themselves to it. The particles are then removed from the bars by an efficient wiping system.

Mode of Operation
The magnetic separator can be installed in the existing system reservoir tank or in its own stand alone external tank. The separator is located in the tank perpendicular to the coolant flow and spans the entire cross-sectional area of the tank to allow interception of the entire system flow.
The magnetic separator is comprised of many magnetic bar chains that are moved through a continuous loop by two rotating assemblies. The bar chains are arranged in parallel to form a magnetic grid through which the dirty coolant must pass. As the coolant travels through the magnetic grid, the ferrous particulates are attracted to the magnetic bars and become attached. Along with the ferrous material, tramp oils which surround the particles are also carried to the bar. As the magnetic bars travel through the coolant, the solids and tramp oil accumulate on the surface of the bars. The bars then exit the coolant and pass through wiping glands which mechanically remove the solids and oil from the bars.
The removed solids are deposited into one of the conveyorized troughs which transport the solids to the end of the separator for discharge. The separator is also equipped with a variable speed drive which allows the regulation of tramp oils being removed.
