Application

In pouring points, hoppers, as inspection before bagging, etc.

Magnetic grids filter very fine magnetic and weakly magnetic ferromagnetic contaminations from free-flowing powders and granulates. Often used for control purposes. Manual cleaning (quick cleaning).
 
They are used for applications in the plastics, food, pharmaceutical, ceramics and other industries. In the hopper of your injection moulding machine, for protection of your installation or as final inspection of your product, e.g. just prior to bagging.
 
Magnetic grids consist of several very powerful Neoflux® (neodymium) magnetic bars. These are located in the middle of your product flow and therefore even capture the smallest ferrous particles, down to 30 microns. Even stainless steel scrapings are captured. These particles are so small that they cannot even be detected by a metal detector.
 
An effective use is to place two magnetic grids in a cascade configuration, so the product flowing past them must contact the magnetic bars or at least pass extremely close to them. We also use this method with our Cleanflow magnets (grids in housing).

Design

Construction & materials data

Goudsmit magnetic grids are available in square and round.
 
The neodymium magnetic bars are provided with enveloping extractor tubes. This makes the grate robust and manual wiping unnecessary. By pulling the magnetic bar unit from the extractor tubes, the captured ferrous contaminants will fall off automatically. We call this 'manual quick-cleaning'.
 
The extractor tubes also serve to protect the magnetic bars, making them last longer.
 

Magnet quality: neodymium N-42, Br 13,300 gauss (at 20 °C), Tmax. 80 °C. (8,000 gauss on tube Ø25)
Materials - in contact with product: AISI304 (RVS 1.4301) / AISI316 (SS 1.4401)


Iron discharging / cleaning

Filtering & discharging of ferrous contaminants

The procedure for discharging the filtered ferrous particles is as follows:

stop the product flow
remove the entire grid from the product chute or hopper and place it on a pre-cleaned, non-magnetic surface (e.g. wood, aluminium or stainless steel)
remove the retainer for the two grid parts
pull the magnetic bars unit out of the extractor housing
the captured metal particles now fall off the extractor tubes. Make sure you keep the magnet bars away from these magnetic metals during this procedure.
lay the part with the magnetic bars on another well-cleaned surface
now make sure you also place the magnetic bars far enough away from the magnetic particles.
dispose of the metal contaminants
if necessary: clean all the grid parts with a dry cloth and/or suitable stainless steel cleaning fluid
mount the two grid parts and the retainer
place the grid back in the product chute or hopper
restart the product flow.

Application

Application

A magnetic head pulley, or head roller magnet, separates ferromagnetic particles, such as iron or steel, and even weakly magnetic particles (such as particles from processed stainless steel) from coarse to very fine fractions and carries them away completely automatically and continuously. This magnetic roller is built into an existing conveyor belt system as a head or tail roller. and is a cost-effective magnetic metal separator. It is important to feed the material onto the conveyor belt with the magnetic conveyor roller in a thin layer (ideally a mono-layer). Magnetic head pulleys require practically no maintenance, and because these magnets are integrated in an existing installation there are almost no extra operating and energy costs.
 
For larger layer thickness a head roller magnet can be combined with a suspension or overband magnet. In this configuration the suspended magnet draws the pieces of steel out of the upper layer and the head roller magnet draws them from the lower layers of the bulk flow. Magnetic head roller separators are particularly well suited for separation of problematic shapes such as ball bearings or batteries. They are used for:

recycling and/or recovery of ferrous metals
removing, purging or eliminating ferrous parts or weakly magnetic particles from product flows
protection of machines (prevention of damage caused by metal particles)


Placement

Placement

Keep the following in mind when integrating a magnetic head pulley:

Use of head scrapers is not possible. Otherwise iron particles would be scraped off before the magnet can separate them.
No steel components in the vicinity of the head roller magnet (such as the splitter: it must be made of a non-magnetic material). Otherwise this part will be magnetized, which has a negative impact on the separation.
The field depth of the magnet.
Type of magnet system in combination with the belt thickness. The optimal placement/position of the separation partition depends on the application.

 
Goudsmit has plenty of experience with this and will be happy to provide recommendations.

Design

Design

Magnetic head pulleys are made in standard sizes and can therefore be easily integrated into an existing installation. The shaft diameter, for example, is suitable for SNL bearing blocks, and the shaft journal (including keyway) is suitable for a standard SEW gear unit. These are global standards and therefore cover most applications. The modular design makes it easy to replace the shaft, which is ideal for maintenance and customer-specific solutions. Various versions available to meet your needs:

Belt width: 400-2000 mm
Diameters: 150-400 mm
Magnet system: both axial and radial magnet construction


Working principle

Working principle

A magnetic head pulley is a head or tail roller that is filled with magnets. This roller forms a magnetic system with a correspondingly rotating magnetic field that is active around the entire circumference. The magnetic field attracts ferromagnetic metal particles in a product flow. The conveyor belt that runs over the roller carries these particles with it to the underside of the roller. When they are no longer in range of the magnetic field they fall off the belt, where they are collected and/or carried away. For strongly magnetic particles, we can place cleats on the belt to 'push' the particles out of the magnetic field.
 
For damp or fine metal particles we fit a scraper to prevent them from sticking to the belt. The advantage of a head roller magnet is that it is a continuous system, so there is no need to stop the product flow to carry off the separated metal particles. This makes the head roller magnet very suitable for product flows with lots of Fe particles. Because the product passes very close to the magnet it is also a very powerful and effective separator.

Application

In pouring points, hoppers, as inspection before bagging, etc.

Magnetic grids filter very fine magnetic and weakly magnetic ferromagnetic contaminations from free-flowing powders and granulates. Often used for control purposes. Manual cleaning (quick cleaning).
 
They are used for applications in the plastics, food, pharmaceutical, ceramics and other industries. In the hopper of your injection moulding machine, for protection of your installation or as final inspection of your product, e.g. just prior to bagging.
 
Magnetic grids consist of several very powerful Neoflux® (neodymium) magnetic bars. These are located in the middle of your product flow and therefore even capture the smallest ferrous particles, down to 30 microns. Even stainless steel scrapings are captured. These particles are so small that they cannot even be detected by a metal detector.
 
An effective use is to place two magnetic grids in a cascade configuration, so the product flowing past them must contact the magnetic bars or at least pass extremely close to them. We also use this method with our Cleanflow magnets (grids in housing).

Design

Construction & materials data

Goudsmit magnetic grids are available in square and round.
 
The neodymium magnetic bars are provided with enveloping extractor tubes. This makes the grate robust and manual wiping unnecessary. By pulling the magnetic bar unit from the extractor tubes, the captured ferrous contaminants will fall off automatically. We call this 'manual quick-cleaning'.
 
The extractor tubes also serve to protect the magnetic bars, making them last longer.
 

Magnet quality: neodymium N-42, Br 13,300 gauss (at 20 °C), Tmax. 80 °C. (8,000 gauss on tube Ø25)
Materials - in contact with product: AISI304 (RVS 1.4301) / AISI316 (SS 1.4401)


Iron discharging / cleaning

Filtering & discharging of ferrous contaminants

The procedure for discharging the filtered ferrous particles is as follows:

stop the product flow
remove the entire grid from the product chute or hopper and place it on a pre-cleaned, non-magnetic surface (e.g. wood, aluminium or stainless steel)
remove the retainer for the two grid parts
pull the magnetic bars unit out of the extractor housing
the captured metal particles now fall off the extractor tubes. Make sure you keep the magnet bars away from these magnetic metals during this procedure.
lay the part with the magnetic bars on another well-cleaned surface
now make sure you also place the magnetic bars far enough away from the magnetic particles.
dispose of the metal contaminants
if necessary: clean all the grid parts with a dry cloth and/or suitable stainless steel cleaning fluid
mount the two grid parts and the retainer
place the grid back in the product chute or hopper
restart the product flow.

Electric drip-feed oiler ELO 24V DC capacity 500ml
Material: Brass nickel-plated. Glass cylinder made from acrylic glass. Voltage: On choice: 230V AC, 50Hz, or 24V DC. Drip rate normal: about 45 drops per 1 ml. Other than the manual drip-feed oiler, which also drips when the machine has stopped, the electric drip-feed oiler only drips as long as the machine is running. When the machine stops, the electric drip-feed oiler is also automatically shut off, as the oiler is controlled via the machine programme. Finest dosing of drops is possible - by turning a knurled nut at the top part of the oiler. Almost all liquids can be dosed drop by drop, provided they are not mixed with solid matters. It is also suited for other media, provided they do not thicken with heat. Attention must be paid to the compatibility with acrylic glass and buna N used as sealing material. (possibly natural glass and vitone sealings on request). Duty cycle: intermittent 20%. Protection class acc. to EN 60529: IP20. Power consumption: 12VA (12W).
