Assembly instructions and user manual drum magnet SxTK magnetic Fe separator 5
General
This manual
This manual contains information for the correct operation and maintenance of your machine. It also
contains instructions to prevent possible injury and serious damage and it ensures the safest and most
trouble-free operation of the machine.
Read this manual thoroughly before putting the machine into operation, familiarize yourself with the
operation and control of the device and follow all instructions precisely.
•The data published in this instruction manual is based on the information available at the time of
delivery.
•We retain the right to amend or modify the construction and/or model of our products at any time
whatsoever without any obligation to modify any previously supplied products accordingly.
Ferromagnetism
The working principle of the device is based on ferromagnetism.
Ferromagnetism is the property that certain materials possess, such as iron cobalt and nickel. Those
materials can become magnetized when exposed to an externally applied magnetic field. Materials that
remain magnetized after the external magnetic field is removed are called permanent magnets. Those
materials are called ‘hard magnetic’.
However, most magnetic materials lose their magnetism after the external magnetic field is removed.
Those materials are called ‘soft magnetic’.
Most alloys of iron, cobalt and nickel are magnetic.
However, some stainless steel alloys like AISI304 or AISI316 are only slightly magnetic.
Because in most cases it will be Fe parts that will be ferromagnetically influenced, we will use the term
‘Fe’ in this user manual when we mean ferromagnetic material.

Safety
Assembly instructions and user manual drum magnet SxTK magnetic Fe separator 11
Danger of magnetic field
The magnets generate a powerful magnetic field that strongly attracts ferromagnetic (Fe) materials.
Always take into account that these materials may suddenly be drawn towards the magnet, very
powerfully. This applies to steel workbenches and steel tools, but also to Ferromagnetic materials
carried on your person, such as coins in your wallet or your keys. Make use of non-magnetic tools and
workbenches fitted with a wooden worktop and preferably a non-Fe frame (for instance stainless steel).
Always be aware that Ferromagnetic parts will be attracted - even personal items -
if you are closer than 0.3 meter to a magnet.
Danger - strong magnetic field!
People fitted with pacemakers should on no account enter the magnetic field
(within a radius of at least 1 meters).
Prohibited for people with pacemakers!
Credit cards, chip cards, computer disks/tapes, computer screens, watches,
etc. may be damaged or destroyed if they enter the magnetic field (within a radius of at
least 0.5 meter).
Danger for magnetic cards!

Assembly instructions and user manual drum magnet SxTK magnetic Fe separator 12
Danger of being caught by moving parts
The only rotating part on the outside of the drum magnet is the rotating axle end. Do not wear or bring any
loose clothing and or materials which may be caught by the rotating axle. Shut down the motor during
maintenance or cleaning process. The safety pictogram is put on nearby the flange in which the drum axle
is hung.
Do not stick any of your body parts through any open hatches of the Drum Magnet during the
operating device.
Danger – being clamped by moving parts
Danger of high voltage
When installing and electrically connecting the device, make sure the activities are performed by qualified
personnel.
Switch off the electrical power supply before performing activities to the device!
Danger – Risk of an electric shock!
Always use the main power switch (on the control box) to switch off the installation in the event of a
dangerous situation.
Do not restore power until the dangerous situation has been resolved!

Device description
Assembly instructions and user manual drum magnet SxTK magnetic Fe separator 13
Device description
Intended use / user indications
Products
To be used for Fe separation out of powders and granular products such as blasting grid, cocoa and
coffee beans, sugar, cattle feeds, fish food, animal meal and ceramic granulates. Also for short-wire
products, such as shredded car tires.
Not to be used in (moist) product that is sticky and/or badly flowing
Fe parts
Suited for product flows with Fe particles of X mm and larger see specifications App. A
Temperatures
Suited for:
•Outside temperatures of -20 °C to +40 °C
•Product temperatures up to +60 °C (Neoflux® magnets) or +100 °C (Ferrite magnets).
The magnet is to be protected against higher temperatures than prescribed, because the magnet might
lose magnetic force permanently when exposed to high temperatures
Free space
Make sure that there is approximately 1 meter of free space around the device to perform and ease the
inspection and maintenance operation.
Noise level
The noise level of the device is less than 70 dB at delivery. Should it become higher, then the device has
to be checked on a breakdown immediately.
Vibrations
The magnet is to be protected against strong external vibrations, because the magnet might lose
magnetic force permanently and or the brittle ceramic magnet material might break.
The only vibrations caused by the device are forced by the rotating magnet drum. The product channel
in which it is placed has to be stiff enough to damp out the (relatively small) forces of the moving drum
with caught Fe parts.
Cleaning
Minimum once per day cleaning of the device is advised for an optimal magnetic separation and to
prevent dirt accumulation on the magnet drum and the problems that can be caused by that. Clean
magnets have the best Fe separation result. So, make sure you clean a little more than you think is
necessary, to achieve a satisfactory result of the magnet device.
For more dirt cleaning: see section Maintenance.

Deliverable specials
High temperatures
When one wants a strong magnetic drum magnet in a hot surrounding (> 80° C for Neoflux®and
> 100° C for ferrite), then the standard magnets cannot be used. For product and or surrounding
temperatures up to 150 °C there is – for instance - the possibility of using special high temperature
Neoflux®magnets. For even higher temperatures other magnet material can be a solution.
Abrasive products
If you have an abrasive product, we can supply the magnet drum and /or inside housing with a protective
coating, like for instance a tungsten carbide coating.
Use in FOOD product flows
The drum magnet product channel (or even complete housing + magnet drum) can be executed in gap-
free SS AISI304 or AISI316, or in combination with other – for instance prescribed or delivered by
customer – food improved materials. Surface treatments like electrolytic polishing, staining, etc. are
possible.
Also, we have a special Neoflux® food grade type added to our product range.
ATEX
The drum magnet is standard not to be used in ATEX zones according EU Guideline 2014/34/EU.
When suited for ATEX, then the ATEX marking is always stated on the Goudsmit identification sticker.
The marking on this sticker is only for the parts, produced by Goudsmit, but one can assume that the
marking is for the overall device as well. The built-in or built-on components that carry their own marking
should have the same or higher ATEX marking as the Goudsmit marking.
When components are built-on or built-in to ATEX devices, they should be of the same or higher ATEX
marking as the Goudsmit marking, stated on the identification sticker.
When using the magnet device in an ATEX zone, it is the users own responsibility to take the right
measures, like in-time cleaning to prevent thick dust layers, suited grounding, electric spark prevention
and air-blow prevention.
Read this manual thoroughly for ATEX measures.

Device description
Assembly instructions and user manual drum magnet SxTK magnetic Fe separator 15
Principle of operation
The principle of operation is the same for all drum magnet types:
`
Drawing: Working principle of standard drum magnet Neoflux® drum magnet in food grade
•The drum consists of a stationary magnet segment and a stainless steel non-magnetic shell.
The drum shell is driven by a motor and resolves in the product. The magnet segment is stationary.
The Fe objects are attracted through the stainless steel shell and “stick” to the casing. The product,
which is non-magnetic, is not attracted and falls straight through to the bottom. The Fe objects are
transported to the non-magnetic part of the drum. Here the - no longer attracted - Fe objects will fall
off the drum, into the Fe outlet. To ensure that the Fe objects are pushed out of the powerful
magnetic field several carriers (ribs) are welded to the casing.
•Raw product – contaminated with Fe – reaches the drum shell through the product inlet.
•An adjustable rubber slat distributes the incoming raw product as close as possible towards the
drum shell. The rubber slat position can be adjusted from the device’s outside, by loosening the
2 nuts at the outside housing and then rotating it towards or from the magnet.
•The filtered product leaves the device through the product outlet.
•A dust suction opening can be used to suck away dust clouds inside the housing.

•The Drum Magnet is to be connected to your equipment by the product inlet flange and the
product outlet flange (make your construction stronger if it is too weak!).
•The top flange has a dust collection opening – with flange holes – on top of which you can mount a
vacuum suction device.
•The bottom flange has an Fe outlet opening – with flange holes.
•By opening inspection hatch 1 you can inspect the drum’s product side.
•A brush strip between the product outlet and the Fe outlet ‘sweeps’ off most unwanted non-
magnetic parts from the shell and also works as a ‘dust curtain’.
•By opening inspection hatch 2 and the 2 side plates, the drum can be dismounted and taken out in
case of any failures / breakdowns.

Magnet construction
In standard execution, the magnet drum is fitted with both ferrite (Ferroxdure) and the 3 times more
powerful Neodymium (Neoflux®) magnets. The Neoflux® magnets ensure an extra high magnet value
on the drum. The Ferroxdure magnets increase the working depth of the magnetic field. An ideal
combination!
In food grade execution, the complete magnet system is powered with Neoflux® magnets, for most
powerful magnet configuration.

Installation
Placing, transporting or moving the magnet
The drum magnet must always be lifted on all 4 lifting lugs!
Mount these lifting lugs only onto the 4 corners of the top flange.
Take the position of the centre of gravity into account. This is not in the middle / centre of the device,
but closer to the motor side of the magnet.
Drawing: Mounting the 4 lifting lugs
•Use only lifting/hoisting and transport equipment that is in good condition and never exceed the safe
working load of the equipment being used.
•Avoid shocks during transport
•Work safely, ensure sufficient working space and use stable and reliable scaffolding, ladders and other
auxiliary equipment to ensure that the device can be installed without risk.
•Be sure your channel construction is strong enough to safely carry the weight of the drum magnet.
The weight is stated on the identification plate/sticker/etching, which is placed on the device housing.

Drum (dis-)assembling
Drawing: Magnet drum lifting
Follow the instructions below for disassembling the magnet drum:
1. Place supporting belts around the flange motor reductor and the shaft at the opposite side. Ensure
that the drum magnet hangs at the same height;
2. Loosen/tighten the side plates’ bolts so the plates are loosened from the housing;
3. Remove service hatch 2 from the housing;
4. For maintenance personnel: clear area all around your work space;
5. Move the magnet drum out of the housing;
6. To ease the maintenance process and eliminate injury risks, it is highly recommended to place the
magnet drum on the floor;
7. Reassembling: in opposite order!
Danger:
The drum is permanent magnetic and will therefore attract Fe or other magnetic parts!

(Re-)Adjusting the magnet segment
Drawing: (re-)adjusting the magnet segment
We have already mounted the magnet segment in the correct position. It will therefore probably not be
necessary to readjust it. If however you have a bad separation because all Fe parts fall down before they
are above the Fe outlet, then you well have to rotate the magnet segment to the correct position. This
can be done as follows :
1. Loosen the clamp bush bolts. The magnet is mounted on the shaft that is now loosened. Rotate the
magnet segment to the desired position by rotating the shaft.
2. For this purpose you can use the aid of the adjustment hole on the shaft on the non-motor side. In
this hole you can place a lever, for instance a long round bar, to apply torque.
The magnet segment should be approximately in the position as drawn in the above drawing (right view).
3. Retighten the clamp bush bolts
False positioning of the magnet segment can cause bad déferrisation. Therefore special attention for
the positioning is very important!
