Introduction

Hump Magnets are made for gravity free-fall applications in magnetic separation free flowing products such as feed, grain, wood ships, food stuffs, sand or plastic where the material flow rate is high & nature of material is lumsy.

It also can be used for granular & powder like material.

Magnetic Hump

Magnetic hump consists of two Magnetic plates mounted in an offset direction & are installed in vertical housing.

Housings handle gravity, moderate positive and negative pressures. The angled shape directs the product flow into the magnetic field & also prevents the bridging & built up of material.

The material falling strikes directly on the first magnet changes direction and falls over the second magnet, ensuring clean outflow material.

FAQ for Magnetic Hump

  • 1) How to clean the magnet?
  • Ans - The magnetic plates are provided with hinges to open it for cleaning. The catched iron on the magnetic plate can be remove by wiping the clothe manually.
  • 2) How to install the magnetic hump?
  • Ans - The ASA standard flanges are provided at inlet & outlet to install the hump 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) What are the variations available?
  • Ans - There are two types of Magnetic humps available. A) 4500 gauss Best for separation of Fine iron B) 1200 gauss Best for separation of tramp iron
  • 6) Can we feed material manually?
  • Ans - No, it is always recommended to use feeding system for regulated & even material feeding. 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.
