Product Description

PML magnetic rods are world-class when it comes to magnetic strengths and precision in dimensions. These rods are made up of magnets, which are fitted inside seamless drawn and heat treated SS 304 L tubes. The thickness of the tubes is optimized to obtain the highest efficiency of the magnets inside. Magnets are hard ferrite ceramic magnets or high-intensity rare earth magnets. The overall construction of the magnetic grills can also be made as per the customer specification and sizes. These magnetic rods, when optimized to handle flow rates and high ferrous material deposition levels, serve as the heart of PML Magnetic grills and Magnetic Filters.

Industries Using Magnetic Rod

FAQ for Magnetic Rod

  • 1) How to clean the magnet?
  • Ans - The magnetic rods are provided on the rotating shaft. To clean the iron, Open the door & wipe our the iron with the clothes. The catched iron on the magnetic plate can be remove by wiping the clothe manually.
  • 2) How to install the Rotary magent?
  • Ans - The ASA standard flanges are provided at inlet & outlet to install the magnet into process line
  • 3) In what direction magnetic hump should be installed?
  • Ans - Vertical direction only.
  • 4) Is it leak proof?
  • Ans - Yes. Gaskets are provided at magnet opening to prevent material leakage.
  • 5) Does it require power supply?
  • Ans - Yes, Center shaft on which rods are mounted rotates with the help of the induction motor.
  • 6) Where it is used?
  • Ans - Rotary Magnet is used to separate iron from sticky, slurry & non free flowing materials. This will help for better iron removal from material.
  • 7) What will be the life for magnet?
  • Ans - It is a permanent magnet it will not loose its magnetism. Magnet can get demagnetized in two cases, a) When it get damaged. b) When magnet get exposed beyond specified operating temperature. But magnet can loose its magnetism 2% to 3% over the span of 5years.
  • 8) Can we recharge the magnet?
  • Ans - No. Magnet cannot be recharged.
  • 9) How we can measure the power of magnet ?
  • Ans - Magnetic intensity can be checked by gauss meter. We also provide calibration services, which we will be valid for 1year
  • 10) How should i select the magnet size?
  • Ans - Please select PML standard model as per material flow rate & type of iron contamination.
