Round Grate Magnet – 150mm Diameter | Minimum 10,000 Gauss

The Round Grate Magnet – 150mm Diameter | Minimum 10,000 Gauss is a compact, high-intensity magnetic separation grate designed to capture magnetically susceptible ferrous contamination from powders, granules and other compatible free-flowing materials. With an overall diameter of 150mm and a magnetic field strength of at least 10,000 Gauss, this round magnetic grate is suitable for installation in compatible hoppers, chutes, processing lines and material-handling systems.

The grate configuration positions magnetic surfaces across the material-flow path, increasing opportunities for unwanted iron and steel particles to come within effective range of the magnetic field. As material passes around the magnetic elements, ferrous contaminants are attracted towards the magnetic surfaces and retained for subsequent removal.

Its compact 150mm round format makes this magnetic separator particularly useful for smaller processing systems and restricted installation areas where effective ferrous contamination control is required.

Minimum 10,000 Gauss Magnetic Field Strength

This round grate magnet provides a specified magnetic field strength of at least 10,000 Gauss.

Gauss is a measurement of magnetic flux density or magnetic field strength at a particular measurement location. A 10,000 Gauss magnetic separator provides a high-intensity magnetic field for attracting magnetically susceptible ferrous particles that pass sufficiently close to its magnetic surfaces.

The specified 10,000 Gauss rating should not be interpreted as a pull-force or lifting-capacity measurement. Magnetic separator performance depends on the complete installation, contaminant characteristics and material-flow conditions.

How Does a Round Grate Magnet Work?

A round grate magnet is designed to position magnetic elements directly within the flow of processed material.

As powders, granules or other compatible free-flowing products pass through and around the grate:

1. Material flows around the magnetic surfaces.
2. Magnetically susceptible iron and steel particles enter the magnetic field.
3. Ferrous contaminants are attracted towards the magnetic surfaces.
4. Captured particles remain on the grate for subsequent removal.
5. The grate is periodically cleaned to remove accumulated contamination.

This provides a straightforward method of incorporating magnetic separation directly into a processing line.

Compact 150mm Round Design

With a diameter of 150mm, this grate magnet is designed for compact processing systems and installations where a larger magnetic grate may not be suitable.

Potential installation locations include:

• Small hoppers
• Round chutes
• Material-feed points
• Powder-processing equipment
• Granule-processing systems
• Compact production lines
• Custom processing machinery

The dimensions of the intended installation should be checked before ordering to confirm compatibility with the 150mm grate.

Ferrous Contamination Capture

This magnetic grate is designed specifically to capture magnetically susceptible ferrous contamination.

Depending on the process and contaminant characteristics, this may include:

• Iron particles
• Steel fragments
• Ferrous fines
• Metal filings
• Small steel particles
• Wear debris from processing equipment
• Other magnetically susceptible contamination

Non-magnetic contaminants such as aluminium, copper, brass, plastic, timber and many grades of stainless steel will not be effectively captured by magnetic separation alone.

Why Use a 10,000 Gauss Grate Magnet?

High-intensity magnetic separation can provide an additional level of ferrous contamination control within industrial processing systems.

A minimum 10,000 Gauss grate magnet can be particularly useful where the process requires strong magnetic fields close to the separator surface.

Potential benefits include:

• Capturing magnetically susceptible contamination
• Protecting downstream processing equipment
• Reducing unwanted ferrous material in processed products
• Supporting product-quality procedures
• Providing reusable contamination-control equipment
• Integrating magnetic separation directly into material flow

Actual separation efficiency depends on the contaminant, processed material and design of the complete system.

Magnetic Attraction Decreases with Distance

The effectiveness of any magnetic separator depends heavily on the distance between the contaminant and the magnetic surface.

Magnetic attraction decreases rapidly with distance.

For effective separation, material should therefore be distributed so that potential ferrous contaminants pass sufficiently close to the magnetic elements.

Factors such as excessive material depth, bridging, high flow rates or poor grate positioning can reduce the opportunity for contaminants to enter the strongest region of the magnetic field.

Magnetic Separation Performance

Actual ferrous contamination-capture performance can be influenced by:

• Contaminant size
• Contaminant shape
• Magnetic properties of the contaminant
• Material-flow rate
• Material depth
• Product characteristics
• Particle size of the processed material
• Distance from the magnetic surface
• Grate position
• Installation geometry
• Amount of contamination already accumulated
• Cleaning frequency

The specified minimum 10,000 Gauss field strength is therefore one important separator characteristic rather than a guarantee that every ferrous contaminant will be captured under all operating conditions.

Permanent Magnetic Operation

The Round Grate Magnet operates using a permanent magnetic system, so no electrical supply is required to generate the magnetic field.

This means there is no requirement for:

• Electrical wiring
• Batteries
• Charging
• Powered magnetic coils
• Electrical switching for magnetic attraction

The grate can therefore provide continuous magnetic separation whenever material passes through the effective magnetic field.

Food and Ingredient Processing Applications

Magnetic grate separators are commonly incorporated into food and ingredient-processing systems to assist with the capture of ferrous contamination.

Potential applications can include processing:

• Flour
• Sugar
• Grains
• Spices
• Powders
• Dry ingredients
• Granular products
• Other compatible free-flowing materials

Where the grate is intended for food-contact use, the material specification, surface finish, fabrication, cleaning requirements and applicable regulatory or HACCP requirements of the complete separator assembly should be confirmed before installation.

Plastics, Chemical and Manufacturing Applications

Round grate magnets can also be incorporated into non-food processing systems.

Potential applications include:

• Plastic pellets
• Polymer granules
• Chemical powders
• Raw materials
• Manufacturing feedstocks
• Recycling materials
• Industrial powders and granules

The suitability of magnetic separation depends on the characteristics of the processed material and the type of contamination being targeted.

Installation Considerations

For effective operation:

• Confirm the 150mm diameter suits the intended equipment
• Position the grate where material can flow around the magnetic elements
• Minimise unnecessary distance between material and magnetic surfaces
• Avoid excessive product buildup
• Ensure the grate is securely installed
• Provide suitable access for inspection and cleaning
• Establish an appropriate cleaning schedule
• Monitor captured contamination as part of routine maintenance

Separator geometry and installation should be designed around the characteristics and flow behaviour of the processed material.

Cleaning and Maintenance

Captured ferrous contamination should be removed from the magnetic grate at appropriate intervals.

Cleaning frequency depends on:

• Contamination levels
• Material throughput
• Process requirements
• Product characteristics
• Quality-control procedures

Excessive accumulation of captured material can reduce the effective magnetic surface available for further separation.

During cleaning, follow appropriate equipment isolation and workplace safety procedures. Remove contamination carefully, inspect the grate for damage or buildup, and correctly reinstall it before restarting the processing system.

Please Note

This Round Grate Magnet has a 150mm diameter and a specified minimum magnetic field strength of 10,000 Gauss.

The Gauss rating describes magnetic field strength and is not a pull-force, lifting-capacity or safe-working-load rating.

Actual magnetic separation performance depends on contaminant size, shape and magnetic properties, material characteristics, flow rate, installation geometry, distance from the magnetic surface and cleaning frequency.

A specific magnetic material or grade, stainless steel grade, surface finish, maximum operating temperature and detailed dimensional configuration have not been supplied and should not be assumed.

This magnetic separator is designed to capture magnetically susceptible ferrous contamination. Aluminium, copper, brass, plastic and many grades of stainless steel are not effectively captured by conventional magnetic separation.

For food, pharmaceutical or other regulated applications, verify the construction materials, surface finish, fabrication, cleaning procedures and compliance requirements of the complete separator system before use.

Strong magnetic fields may affect pacemakers and other medical implants, magnetic storage media and sensitive electronic equipment.
