OSENC Magnetic Separation
Custom Magnetic Grate for Powder and Granule Iron Removal
Multi-Tube Protection for Gravity-Fed Material
A magnetic grate arranges multiple magnetic tubes in a round, square, or rectangular frame so gravity-fed material passes near magnetic pole areas. Choose the frame from the opening, particle size, flowability, capacity, target iron, tube diameter and spacing, row arrangement, temperature, cleaning frequency, and removal space.
When a Magnetic Grate Fits
- Best for
- Dry, free-flowing powders, pellets, and granules in hoppers or chutes.
- Installation
- Inside an existing opening with suitable support and removal access.
- Cleaning
- Remove and wipe/scrape tubes, or review a confirmed easy-clean structure.
- Main risk
- Bridging, bypass, buildup, insufficient open area, or unsafe removal.
Frame and Row Options
Potential shapes include round, square, and rectangular frames; arrangements may be single, multiple, or staggered rows. These are design directions, not confirmed standard sizes. Additional rows can improve contact opportunity but reduce open area and increase bridging or pressure loss.
Tube Spacing Controls Flow and Contact
| Closer spacing | Wider spacing |
|---|---|
| More opportunity to pass near magnetic surfaces | More open area for large or cohesive material |
| Higher blockage and buildup risk | Higher bypass distance between tubes |
| May suit fine free-flowing powder | May suit larger granules or higher flow |
Use the actual maximum particle/agglomerate size, moisture, surge flow, tube diameter, and cleaning condition. Do not copy a gap from another powder.
Standard vs Easy-Clean Grate
A standard grate uses magnetic tube surfaces that are cleaned manually. An easy-clean magnetic grate uses removable magnetic cores and collection sleeves to reduce scraping. Easy-clean adds sleeve thickness, mechanism, withdrawal distance, and inspection requirements; it is not automatically the better choice for infrequent cleaning.
Grate vs Drawer Magnet
A grate uses the customer’s surrounding hopper or chute. A drawer magnet adds an enclosed housing, inlet/outlet, and guided pull-out access. Choose the drawer when the line needs a defined enclosed connection; choose a grate when the existing opening and access are suitable.
Materials and Sanitary Boundary
Confirm frame/tube stainless grade, welds, finish, surface roughness, seals where applicable, temperature, cleaning chemicals, and documentation. Stainless construction alone does not establish FDA approval, food-contact suitability, pressure rating, or sanitary design.
Magnetic Testing
Define field readings at identified tube or sleeve points, instrument, temperature, tolerance, and sampling. For a finished grate, also inspect dimensions, spacing, frame flatness, welds, surface, removal fit, and polarity. Material performance requires a representative flow test, not only surface Gauss.
Cleaning and Commissioning
- Inspect frequently during initial operation.
- Record captured iron and product buildup.
- Clean before buildup shields the surface or restricts flow.
- Inspect tubes, frame, welds, supports, and removal access.
- Set the interval from real accumulation and process risk.
RFQ Information
Send opening drawing, material, particle size, bulk density, capacity/peak flow, moisture, temperature, target iron, frame shape, row preference, cleaning frequency, available removal space, stainless/finish, and test requirement.
Magnetic-Grate RFQ Inputs
The quotation should describe gravity-fed powder or granules spread across an opening and connect each proposed feature to an operating or acceptance requirement.
| Selection logic | Choose grate dimensions, row count and tube spacing from flow coverage, bridging, target size and required cleaning interval. |
|---|---|
| Application inputs | Material, particle-size range, bulk density, moisture, cohesion, temperature, target contamination and normal and peak flow |
| Mechanical interface | Provide opening shape and dimensions, frame and support details, product head, extraction direction and full cleaning clearance. |
| Cleaning and service | Define whether the line stops, how the grate is lifted, where iron is released and how it is prevented from returning to product. |
| Acceptance method | Agree tube magnetic test positions, dimensions, materials, surface condition and a representative flow test if blockage or residual contamination is critical. |
Project Scope and Supply Boundary
Boundary for Custom Magnetic Grate for Powder and Granule Iron Removal
- This is a configurable project page, not a released standard model with universal published performance.
- We confirm the manufacturing route, approved drawing and opening and interface, tube layout, contact materials, shell or sleeve construction, extraction space, cleaning method and flow behaviour for the inquiry.
- Dimensions, magnetic values, pull force, capacity, separation result, materials, certification, lead time and warranty become project facts only in traceable quotation, drawing, inspection or order documents.
Combustible Dust and Hazardous-Area Boundary
- For the powder or granular product, the plant owner must identify any combustible dust, vapour or gas and provide the site hazardous-area classification.
- No-coil permanent equipment is not automatically suitable: assess impact, friction, static, hot surfaces, bearings, drives, sensors and controls in the complete configuration.
- Confirm zone or division, substance and ignition data, dust layers, temperatures, earthing and bonding, cable entries, ingress protection, cleaning and destination-country rules.
- Do not claim explosion-proof or ATEX suitability until configuration-specific marking, declaration, instructions and evidence are verified.
How We Turn This Product into a Project Proposal
Custom Magnetic Grate for Powder and Granule Iron Removal: seller-side application review
- Your buying problem: A catalogue name does not confirm that the magnetic circuit, capacity, cleaning method and installation envelope fit your material or production line.
- What we review: We confirm your material, particle size, moisture, temperature, throughput, contaminant type and size, working distance, interfaces, space, environment and cleaning frequency.
- What we supply: After feasibility and drawing approval, we configure the product scope and coordinate manufacturing and inspection through the appropriate qualified resources.
- Buyer value: This helps you avoid blockage, missed contamination, difficult maintenance, interface rework and paying for magnetic performance that cannot be used at the real working gap.
- Boundary: We do not treat website dimensions, Gauss, capacity, certification or lead time as final until they are confirmed in project documents.
- Next step: Send the material and target, particle range, moisture, temperature, throughput, contamination, installation drawing, available space, cleaning preference and any sample or site video. Send your material and interface data
Project Support
