Prong Magnets

STAR TRACE's Prong Magnets are designed to extract the ferrous materials from the slurry or liquid raw materials in order to purify the material in the production process. Strong magnetic tubes filter the flow and extract the unwanted ferrous metal. The unit is simply connected to the existing pipeline via flanged or threaded ends. Simple and easy access is possible using the quick release lid. Cleaning of the magnets is easily accomplished by removing the cover plate of the housing and sliding out each magnet assembly.

Prong Magnets Applications

  • All units incorporate a sump type housing to trap non-ferrous particles.
  • Efficiently remove tramp iron before maintenance and product contamination problems occur.
  • Liquid Trap Magnets are engineered to remove ferrous contaminants from liquid and slurry lines.
  • Liquid Traps may be installed horizontally, vertically, or on an angle without affecting their magnetic efficiency.
  • The benefits of this magnetic separator can be experienced in most cases with no appreciable pressure drop or reduction in flow rates.

Prong Magnets Types

Cage Style "T" Traps:

liquid line separators T

T-Trap Magnetic separators are designed for heavy duty, large volume liquid and semi-liquid line flow systems. The T-Trap employs a slip-in cage of stainless steel permanent magnetic tubes, which capture ferrous tramp metal particles and improve the purity of the product. As the particles collect, they migrate to the rear of the tubes where they remain protected from wash-off until the tubes are cleaned. With its top access bolt-on steel plate and seal, the T-Trap is easy to clean. Simply remove the top, lift out the magnet cage, wipe clean and reinstall. Available in 7 standard line sizes from 2" to 18" inches in diameter, STR T-Trap's can also be produced to meet special applications. EZ-Clean upgrade packages are available for some styles of manual clean, cage style T-Traps.

Cage Style "T" Traps:

liquid line separators

When tramp metal protection is required for liquid lines carrying viscous to fibrous products, the plate style T-Trap is ideal. This magnet allows the product to flow through the housing without causing product bridging. An interior baffle is used to direct the entire product flow towards the powerful plate magnet, ensuring that tramp metal is forced into the magnetic field. Installation of the plate style magnet can be in any position. Vertical position eliminates the sump area, and in horizontal lines, cleaning is made easier when the magnet element is installed on top. Available in standard line sizes of 2" and 3" diameters. STR can also manufacture magnets for special applications or line sizes.
