Product Description

Magnetic Drum Separators are of self-cleaning type and provide continuous removal of ferrous contamination from a wide range of free-flowing bulk and granular materials in high-volume applications.
Drums can be ordered with or without housing.
Magnetic Drum Separator system is a complete machine with Stainless Steel 304 / 316
Housing & Drive system. Only the drum separator unit can also be supplied.
The Drum Separators are available in two types:
High Intensity – (Ndfeb Magnet – 4500 gauss), for Operating Temperature of 80˚C(Max.)
Low Intensity - (Ferrite Magnet - 1200 gauss), for Operating Temperature of 250˚C(Max.)
Ferrous fine particles, nuts, bolts, pins, nails and other tramp metal from free-flowing granular material can be arrested effectively.

How to use Magnetic Drums?

Drawing of magnetic drum separator Working process drawing of Drum separator

When material flows onto the drum, a stationary magnetic assembly inside the unit's shell captures tramp metal and holds it securely to the drum's stainless steel surface. With contaminants removed, the good product falls freely to a discharge point. As the drum rotates, cleats sweep the ferrous debris through and out of the magnetic field. The tramp metal is discharged separately, creating continuous self-cleaning separation. PML is drum separator manufacturer in india.

FAQ for Magnetic Drum Separator

1) How much maximum magnetic power can be get?
Ans - 4500 Gauss. Which is sufficeint to remove the fine size iron contamination.

2) How to clean iron particles from drum?
Ans - Drum seoarator is a self cleaning system. It separates iron & non iron material through two different outlets.

3) Where to install it?
Ans - Below material feeding system like screw conveyor, bucket elivator, conveyor belt, vibro feeder etc.

4) Does it require power supply?
Ans - Yes, Magnetic drum rotates with the help of the induction motor. PLC & VFD can configured witht the system.

5) What is the drum rpm rate?
Ans - 20 rpm.

6) Can we feed material manually?
Ans - Yes but it is always recommended to use feeding system for regulated & even material feeding. This will help for better iron removal from material.

7) How should i select the magnet size?
Ans - Please select PML standard model as per material flow rate & type of iron contamination.

8) 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.

9) Can we recharge the magnet?
Ans - No. Magnet cannot be recharged.

10) 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

11) What is the M.O.C for the Housing, Hopper & Structure.
Ans - M.O.C for the drum, housing, hopper is stainless steel only, Structure of the drum separator is made up of MS.

12) Is this magnetic drum separator efficient to remove 100% iron contamination from the material?
Ans - It is advisable to use 2 stage drum separator, so that material can be double passed for more separation. OR Customer can install Magnetic grill of 11000 gauss at outlet of the system.
