Grate

These Magnetic Grates remove ferrous contaminants/impurities from free-flowing products (black carbon, chemicals, cosmetics, plastics, and food industry materials) as they pass by the magnetic grates. These units can easily be installed in any hopper, floor opening or duct.

Application:

This magnetic grate can be used to separate ferrous metals from the following materials:

Dry powders, granular products, and other small products that may contain fine contaminants.

Construction:

Our stainless-steel magnetic grates consist of a row of magnetic bars (inside a stainless-steel shell) that are attached to a stainless-steel frame. This frame typically comes in either a square, rectangular, round, oval, triangular, rhombus or polygonal shape. (However, we can custom build a different shaped frame for you to suit specific installations.) In most cases, the bar - centre distance is usually 2 inches.

Features:

• Finish: Food grade high gloss polish, and food grade welding.
• Material: SS304, SS316 and SS316L seamless steel tube.
• Working Temperature: Our magnetic grates are typically made to work in temperatures below 80 °C. However, we do have specialist magnetic grates that can work in temperatures of up to 350 °C.
• Available Designs: Standard, Easy Clean, One Layer, Multilayer and Custom designs.

Easy Clean Design:

The magnetic grate’s clever design makes cleaning a breeze. Simply pull out the magnetic core and the ferrous impurities will fall from the stainless-steel shell (Figure 01 - 02).

Multilayer design:

The image below (Figure 06) is that of a double-layered magnetic grate.

The addition of extra layers to your magnetic grate increases the amount of magnetic force acting upon the ferrous contaminants, which results in an increased number of ferrous particles being removed from your products.

We can add baffles onto the magnetic grates to direct material onto or closer to the rods to attract more contaminants.

Baffles can either be small rods or special rods bent at a 90° angle to direct the material closer to the rods (Figure 03 and 05).

We recommend that you purchase our grates with handles if you need a larger magnetic grate. Not only do the handles make it easier for you to use the magnetic grate, but it also enables you to use the grate without needing to touch the contaminants. Another advantage of adding handles is avoiding hand contact with contaminants.

Liquid Traps

Magnetic liquid traps are designed to remove ferrous materials from liquids, semi-liquids and powder conveying air. Highly magnetic tubes inside the housing filter the product by attracting the unwanted ferrous metal to itself as the rest of the product passes by the magnetic tubes. This unit is mounted on top of the existing pipeline via flanged or threaded ends. Easy access is also possible using the quick release clamp.

Application:

The unit is suitable for liquids, semi-liquids and powder conveying air.

Construction:

Magnetic liquid traps consist of a group of magnetic bars and a form of housing. Inlets and outlets allow simple mounting to the existing pipeline via various connection types, flange, union and quick release clamps.

Features:

• Finish: Food grade high gloss polish, and food grade welding.
• Material: SS304, SS316 and SS316L seamless steel tube.

Drawer

The Magnetic Drawer is ideal for removing fine to medium ferrous contaminants from a range of free-flowing dry products. The magnetic bars inside the housing emit a high magnetic field across the gaps between the bars. When material flows into the top of the housing, it is forced to cascade in a zig-zag pattern from row to row over the magnetic tubes. This action maximises the amount of ferrous metal captured during the filtration process as the product repeatedly comes into contact with the magnets as it travels through the housing. As a result of its effective removal of ferrous contaminants, these magnetic drawers are widely used in the food and chemical industries.

Application:

Magnetic Drawers can be used to effectively separate ferrous metals from the following materials:

Dry powders, granular products, and other small products that may contain fine contaminants.

Construction:

The drawers are constructed with one or multiple magnetic grates and housings - depending on your requirements. Then the draw is installed within the pipeline.

Features:

• Finish: Food grade high gloss polish, and food grade welding.
• Shell Material: SS304, SS316 and SS316L seamless steel tub.
• Magnet: High strength rare-earth magnet.
• Working Temperature: Our magnetic grates are typically made to work in temperatures below 80 °C. However, we do have specialist magnetic grates that can work in temperatures of up to 350 °C.
• Type of Mounting: Flange or quick release clamp.
• Easy clean option available.
• Custom designs can be manufactured.

Cleaning:

To ensure that these units are operating efficiently, they should be regularly inspected and cleaned. To clean the magnetic tubes, release the latch first and open the door. Remove the grate assemblies one at a time. Remove the ferrous metal by hand. Use extreme caution and wear gloves during the process.

Rotary Separator

Rotary separators are used to remove ferrous contaminants from material that is prone to caking and bridging. Highly viscous materials like honey, syrups, or gels tend to plug, cake, and bridge inside a typical fixed magnetic separator.  Unlike fixed magnetic separators, rotary separators prevent the viscous material from caking and bridging inside the magnetic separator due to its consistent rotating motion. This rotating motion circulates the viscous material - which allows more ferrous contaminants to be attracted to the rods and later removed from the product flow - while simultaneously breaking up any lumps inside the product.

Note: The capacity of this unit is greater than that of our other fixed separators.

Application:

Products with low moisture, and products with mildly viscous that have bridging problems.

Construction:

The rotary separator consists of a cyclic rotary magnetic bar group and a housing. A motor is used to drive the rotating rods.

Features:

• Finish: Food grade high gloss polish, and food grade welding.
• Material: SS304, SS316 and SS316L seamless steel tub.
• Magnet: High strength rare-earth magnet.
• Working Temperature: Our magnetic grates are typically made to work in temperatures below 80 °C. However, we do have specialist magnetic grates that can work in temperatures of up to 350 °C.
• Type of Mounting: Flange or quick release clamp.

Plate

Plate magnets are designed to be used as a part of a conveying process or in chutes. They are mounted at the conveyor outlet above the conveyor belt.

Application:

This separator removes ferrous materials from dry powders, semi-dry powders, and other granular materials on a belt conveyor.

Construction:

The magnet inside the plate is usually a Ferrite or a rare-earth magnet. They are assembled regularly to optimise performance. We can make a wide range of plates designs to work effectively with your product volume and product flow speeds.

Plain Face (PF)

This plate is designed to be placed above your products/materials, e.g. suspended, or installed inside chutes and ducting (as seen in the above image).

Exposed Pole (EP)

This type of plate uses two steel plates which are welded onto the plate’s surface. The exposed pole is used to capture ferrous contaminants from low flow materials (pictured below).

Tapered Trap (TT)

A trap is added on the plate's surface to prevent captured ferrous contaminants from being washed away by oncoming material. The trap's face can either be plain (EP) or tapered (TT). This plate features a tapered step trap positioned between the north and south magnetic fields so that the underside of the plate can collect and trap the ferrous contaminants Preventing wash off from the oncoming product. As such, tapered traps are designed to remove ferrous contaminants from conveyor belts with high volume product flows (pictured below).

Suspended Plate Magnet

Before installing a suspended plate magnet, you must calculate the appropriate plate suspension height, plate width, and minimum magnetic strength. The magnet's suspension height should be high enough to not obstruct the flow of your products while also being low enough to remove the ferrous contaminants from your products. Your plate magnet's width must also be the same as your conveyor. You must also select a plate magnet that is strong enough to remove the ferrous contaminants from your products. In general, the further away your plate magnet is suspended from your conveyor belt, the stronger the plate magnet needs to be. Keep in mind a shallower product stream will significantly improve your plate's magnetic ability to remove the ferrous contaminants from your products (see below).

Features: 

• Finish: Brushed or sand blasted. 
• Material: SS304. 
• Magnetic Strength:  Multiform magnetic strength standard to choose. 
• Working Temperature: Our magnetic grates are typically made to work in temperatures below 80 °C. However, we do have specialist magnetic grates that can work in temperatures of up to 350 °C. 
• Installation: Hinges, hang rings, latches etc. can be added to the plate. 
• Custom designs can be manufactured.

Plate Separator

The plate separator is like a feed pipe, with a magnetic plate on one or both sides by the hinges and latches. The magnetic separator is installed by removing part of the feed pipe is removed and replaced with the magnetic separator. As the product enters the magnetic separator it will stream down to the plate magnet where the Ferrous contaminants will be extracted from the flow.

Application:

This unit can be used to effectively remove medium to large contaminants (nuts, bolts, nails etc.) from dry powder or granular materials.

Hump Magnets:

This type of separator is built to be used with vertical pipelines. This type of separator is constructed with two plate magnets mounted in an offset housing on opposite sides. As the product enters the housing, it hits the face of the first magnet. Then it travels at an offset angle to the housing and hits the second magnet. This process provides dual separation results for high volume, poor-flowing materials.

Magnetic Chute:

This is another vertical pipeline that does not require as much height as a hump magnet to install. This type of magnetic separator is ideal for situations where mount space is limited. The two highly magnetic plates - fixed on opposite sides of the housing - capture contaminants as the product travels through the pipeline. An angle deflector placed in the centre of the inlet pushes the product toward two opposite plates where the contaminants can be collected and trapped by the magnetic plates (pictured below).

Bullet Magnet

Bullet magnets are designed to remove larger pieces of ferrous materials, e.g. nuts, bolts and nails, from your products to prevent them from damaging other downstream machines. This machine is typically installed in either gravity or pneumatic pipelines.

Application:

All dry powder and granular products such as grain, powder and feed. 

Construction:

The rotary separator consists of a magnetic core in the centre of a stainless-steel housing. The magnet is cone-shaped to ensure smooth flowing. During operation, the powerful cone-shaped magnet is used to capture ferrous contaminants.

Features:

• Finish: The interior is polished to a high gloss mirror-like finish. The exterior of this machine has a brushed or sandblasted finish. 
• Material: SS304. 
• Magnetic Strength: Multiform magnetic strength standard. 
• Custom designs can be manufactured

Specified Sizes

Cleaning:

The cone is attached to the door. As soon as you open the door, you will be able to have access to the cone. Put on your protective gloves and then remove the contaminants from the cone.

Drum Separator

Our drum separator is designed to continuously remove metal contaminants from product flow streams. This machine is purpose-built to remove ferrous contaminants from dry, bulky products with a high concentration of iron contaminants.

Application:

This machine is suitable for removing iron contaminants from typically dry, and bulky products. 

Construction:

The main advantage of this machine, over other machines, is that it does not need to be turned off and cleaned by hand. The separator consists of a housing that contains a drum magnet. The drum magnet has a stationary internal 180 ° magnetic arc while the other half is non-magnetised. When material drops onto the drum's outer surface, the ferrous contaminants will become attached to the magnetic part while the product passes through to the other side. As the drum cover is constantly rotating, the ferrous contaminant will flow through to the non-magnetised area and dropdown.

Features:

• Finish: The interior is polished to a high gloss mirror-like finish. The exterior of this machine has a brushed or sandblasted finish.
• Material: SS304.
• Magnetic Strength: Multiform magnetic strength standard.
• Custom designs can be manufactured.

Pulley

The operating principle of the magnetic pulley is similar to that of the magnetic drum. Like the magnetic drum, the magnetic pulley works without needing to be stopped and cleaned. Usually, the magnetic pulleys are installed at the end of the conveyor belts to remove the ferrous contaminants. As the product gets conveyed along towards the end of the conveyor belt, the product passes over the pulley. While passing over the pulley, the ferrous metals become attracted to the pulley (underneath the belt) and stick to the belt while the rest of the product exits the conveyor belt. The ferrous contaminants will cling to the pulley (on the underside of the conveyor belt) until it exits the pulley's magnetic field and falls off.

Application: This machine is suitable for removing iron contaminants from typically dry, and bulky products.

Construction: The roller's shafts can be machined to suit existing bearing detail which ensures an easy installation with minimal downtime.

Features:

• Material: SS304 outside.
• Magnet: Either rare-earth magnet or Ferrite magnet.
• Suitable for bulk materials, e.g. minerals, wood chip, recyclables, etc.
• Custom designs can be manufactured

Force Tester

The force tester helps users to monitor the efficiency of their magnetic separator by measuring its holding force. This test is designed to be used on a variety of magnetic separators, especially the bar magnet.

Application:

The tester should be used to monitor the separator's performance over time and not the exact magnetic strength of the separator. You should record the force tester's pull results from periodic inspections to evaluate any changes in your separator's magnetic performance.

Construction:

A graduated scale body with a maximum pulling force range of 49.03N (5000 g) and a steel ball.

Operation Guide:

• Reset the tester to zero
• Attach steel ball to the separator and position the scale perpendicular to the magnet’s surface.
• Slowly pull the tester away from the magnet.
