Corvelan Quality Control
Magnetic Separator Quality Control & Testing
Corvelan structures inspection around the actual equipment configuration, approved interfaces and agreed acceptance requirements instead of relying on a generic “high quality” statement.
Magnetic condition, mechanical fit, functional operation and material-separation performance are different questions. The test method should match the decision that needs to be accepted.

Inspection Philosophy
Quality Checks Based on Your Magnetic Separator Requirements
A useful quality process starts by checking the key requirements of the equipment. These may include dimensions and interfaces, magnetic condition, mechanical operation, electrical function, material separation and shipment details.
These are not interchangeable. A dimensional inspection cannot prove material recovery. A surface magnetic reading cannot prove capture performance in a moving material bed. A sample trial cannot replace confirmation that the supplied equipment matches the approved drawing.
Corvelan therefore separates equipment identity, build quality, magnetic measurements, functional checks and process trials so each result is used for the decision it can actually support.
See how Corvelan checks magnetic separator components, dimensions, magnetic conditions, mechanical and electrical function, material trials, FAT items and shipment scope.
Measurement point, test method, equipment configuration and acceptance basis should remain attached to the result.
QC Coverage
What Corvelan Actually Checks Before Shipment
The exact checkpoints depend on separator type and project scope. A magnetic grate, suspended magnet, magnetic drum and driven overband require different inspection points, so the checklist must follow the actual equipment configuration.
Fabrication & Dimensions
Machining, welding, critical geometry, mounting points, housings, clearances and installation interfaces.
Magnetic System
Magnetic circuit configuration, pole arrangement, effective magnetic zone and defined magnetic measurements.
Mechanical Function
Rotation, belt tracking, bearings, shafts, cleaning devices, splitters, discharge components, guards and fasteners.
Electrical Function
Motor, control cabinet, wiring, grounding, protection, interlocks and emergency functions where those systems are included.
Operating Check
No-load or functional checks of movement, noise, vibration, drives, cleaning and discharge behavior where relevant.
Material Trial
Representative sample testing when the buying decision requires evidence of a defined process result.
Shipment Scope
Final equipment identity, accessories, records, loose items, labels, protection and packing against the accepted order scope.
Process Overview
A Quality Process That Follows the Equipment Through Production
The exact quality checks depend on the separator type and project requirements, while ensuring the delivered equipment matches the approved design.
STEP 01
Review Equipment Requirements
Identify equipment type, drawing revision, interfaces and agreed inspection requirements.
STEP 02
Check Manufacturing Quality
Check relevant incoming components, fabrication, dimensions and assembly points.
STEP 03
Check Equipment Operation
Perform magnetic, mechanical and electrical checks that match the separator configuration.
STEP 04
Perform Required Testing
Complete material trial or defined acceptance test where it forms part of the project scope.
STEP 05
Final Shipment Check
Check final configuration, records, accessories and packing before dispatch.
Incoming Inspection
Check Critical Components Before They Disappear Inside the Assembly
Purchased and fabricated components can affect alignment, service life, magnetic configuration and installation fit. The relevant incoming checks should be defined by the equipment design rather than copied from an unrelated machine.
- Structural steel / stainless parts
- Magnetic components
- Shafts and machined parts
- Bearings and housings
- Motors and gearboxes
- Belts and drive components
- Electrical components
- Project-specific purchased items
Project records matter.
Where a material certificate, supplier document or component identification is contractually required, it should be linked to the agreed project requirement instead of implied as a universal certificate.
Fabrication & Dimensions
Control the Dimensions That Decide Whether the Separator Fits and Runs Correctly
For industrial magnetic separation equipment, dimensional quality is not cosmetic. Incorrect mounting geometry, shaft position, chute interfaces, splitter location or working clearance can change installation, material flow and separation conditions.
- Critical overall dimensions
- Mounting-hole locations
- Inlet / outlet interfaces
- Shaft and bearing fits
- Drum / pulley alignment
- Housing geometry
- Splitter / discharge position
- Cleaning-access clearance
- Guarding interfaces
- Surface condition where specified
Fit is part of quality.
A separator that meets a magnetic reading but cannot be installed at the approved working distance is not an acceptable project outcome.
Magnetic System Measurement
Separate Magnetic Configuration From Process Performance
Magnetic circuit assembly and magnetic measurements can confirm defined characteristics of the supplied magnetic system. They should not be presented as automatic proof of recovery, removal rate, purity or throughput in a production process.
Configuration Checks May Include
- Magnetic element arrangement
- Pole orientation
- Magnetic zone position
- Magnet assembly location
- Agreed magnetic geometry
- Specified measurement locations
Magnetic measurements show the magnetic condition of the equipment, while actual separation performance depends on the application.
A magnetic measurement describes the magnetic condition at the defined test point and method. Material behavior in the real process still depends on feed presentation, working distance, target properties, geometry and operating conditions.
Use the Right Test
Testing Methods Used to Check Magnetic Separator Performance
Before inspection, we agree on what will be measured, the test conditions and the pass criteria. Combining unrelated tests into one headline “magnetic strength” statement creates false confidence rather than useful evidence.
METHOD 01
Defined Magnetic Field Measurement
Measures magnetic flux density at a stated point under a stated method.
Record
- Instrument
- Measurement point
- Probe orientation
- Surface / gap / working distance
- Relevant condition
Can Support
Confirmation or comparison of a defined magnetic condition.
Cannot Prove Alone
Capture rate, recovery, purity, product loss or production throughput.
METHOD 02
Defined Pull-Force Test
Measures the force required to release a defined test piece using a controlled fixture and method.
Record
- Test piece / fixture
- Contact or spacer condition
- Pull direction
- Instrument
- Test location
Can Support
Repeatable comparison or monitoring when the same method is maintained.
Cannot Prove Alone
Behavior of real bulk material moving through the separator.
METHOD 03
Representative Material Trial
Tests the selected setup with actual or representative material under recorded operating conditions.
Record
- Sample identity and condition
- Feed presentation
- Equipment configuration
- Test Conditions
- Sampling / calculation method
Can Support
The result achieved with the tested sample under the recorded test conditions.
Cannot Prove Alone
Performance outside the tested material, scale or operating conditions.
Functional Inspection
Mechanical and Electrical Checks Must Match the Separator Type
Corvelan does not assume every magnetic separator needs the same checklist. Driven equipment, passive magnetic components and electromagnetic systems require different inspection points.
M
Mechanical Inspection
Typical checkpoints may include:
- Shaft rotation / runout
- Drum or pulley movement
- Belt tracking
- Bearing condition
- Scraper operation
- Splitter position
- Cleaning mechanism
- Discharge movement
- Fasteners
- Guards
E
Electrical & Control Inspection
Where applicable, checkpoints may include:
- Motor identification
- Wiring condition
- Control cabinet
- Grounding
- Protection devices
- Control response
- Interlocks
- Emergency functions
- Cable interfaces
- Project-specific I/O
The inspection items above are examples of common quality checks. The actual inspection scope depends on the magnetic separator type, configuration and project requirements.
No-Load & Functional Test
Verify the Equipment Behaves Correctly Before a Process Trial
Where the separator has driven or moving systems, functional testing can identify assembly, tracking, movement or control issues before the equipment is released for shipment or material testing.
- Rotation direction
- Belt / drum movement
- Tracking behavior
- Unusual vibration
- Abnormal noise
- Drive operation
- Cleaning mechanism
- Discharge mechanism
- Control response
- Accessible safety functions
Functional test ≠ separation performance test.
A machine can run correctly without proving that it meets a material recovery or contamination-removal target. If that decision matters, use an agreed material trial.
Material Testing
Test Performance With a Representative Material Sample
Material testing is most useful when the actual magnetic response, contaminant behavior, separator route or required process result cannot be judged responsibly from drawings and catalog data alone.
01 DEFINE TESTING PURPOSEWrite the separation question and acceptance metric before the test starts.
02 CHECK MATERIAL SAMPLEConfirm sample identity, physical condition, representativeness and handling scope.
03 RECORD TEST CONDITIONSRecord relevant feed method, working distance, speed, gap, configuration and other variables.
04 RUN THE TESTKeep agreed variables controlled so the comparison can be interpreted.
05 MEASURE THE RESULTCollect the required fractions or measurements using the agreed method.
06 EXPLAIN TEST RESULTSRecord the test result and identify any checks still needed on the production line.
A successful sample test is not an unconditional scale-up guarantee.
Material variability, feed presentation, working distance, equipment geometry and production operating conditions must stay attached to the interpretation of the result.
Equipment-Specific QC
Different Magnetic Separators Need Different Acceptance Points
Quality control becomes more useful when it follows the real separator geometry and process duty instead of forcing every product into the same generic checklist.
Magnetic Drum Separator
Review drum geometry, shaft and bearing condition, rotation, magnetic zone, splitter or discharge arrangement, clearances and defined magnetic measurements.
Suspended / Overband Magnet
Review magnetic assembly, mounting interfaces, working-clearance basis, belt and drive systems where included, discharge direction and cleaning function.
Magnetic Head Pulley
Review pulley dimensions, shaft interfaces, magnetic zone, belt-related geometry, rotation, working arrangement and magnetic/non-magnetic discharge paths.
Magnetic Grate / Tube
Review magnetic element layout, surface condition, fit, cleaning arrangement and a defined magnetic or pull-force test where required.
Drawer Magnet
Review tube or magnetic element arrangement, drawer movement, sealing and interfaces, cleaning access and relevant magnetic checks.
Custom Magnetic System
Build the inspection plan around the approved drawing, magnetic function, mechanical interfaces, process position and project-specific acceptance criteria.
Final Inspection & FAT
Confirm the Supplied Equipment Against the Accepted Project Scope
Final inspection should close the loop between what was approved, what was built and what is being packed. Where a formal Factory Acceptance Test is agreed, the test items and acceptance rules should be written before the FAT begins.
1
Equipment Identity
Confirm the machine or assembly being inspected matches the accepted project and configuration.
2
Drawing & Interface Check
Review agreed critical dimensions, mounting points, material interfaces and project-specific geometry.
3
Functional & Magnetic Checks
Complete the defined tests that apply to the actual separator configuration.
4
Accessories & Documentation
Confirm loose items, supplied accessories and agreed project documents before packing.
5
Release for Packing
Verify that open inspection issues affecting shipment have been addressed before release.
Inspection Records
Testing Is More Valuable When the Result Can Be Traced Back to Its Method
The useful record is not merely “PASS.” It should preserve enough context to understand what was inspected, how it was measured and which equipment or project condition the result belongs to.
Inspection Checklist
Equipment identity, relevant checkpoints, result and inspector record for the agreed scope.
Measurement Record
Defined location, distance or fixture, instrument, method and recorded magnetic result where required.
Functional Test Record
Applicable running, movement, drive, control and mechanical observations for driven equipment.
Material Test Record
When material testing is included, the report records the sample, test conditions, measurements, results and any follow-up work.
Configuration Reference
Approved drawing or configuration basis used to determine which build and interface details were checked.
Acceptance Record
Project-specific FAT points and acceptance results when a formal factory acceptance scope has been agreed.
Inspection Photos
Project photos can support traceability when the required inspection or shipment evidence calls for them.
Packing Check
Equipment, loose items, protection and agreed shipment accessories checked before dispatch.
The quotation or technical scope states which project records are included with the order and the format in which they will be supplied.
Packing & Shipment Check
Quality Control Does Not End When the Machine Passes Its Test
A correctly built separator can still arrive with missing loose items, exposed interfaces or transport damage if shipment preparation is careless. Final packing checks should follow the actual equipment size, weight, geometry, lifting points and shipment method.
- Equipment identity
- Loose accessories
- Exposed interface protection
- Moving-part restraint where needed
- Moisture / surface protection where required
- Labels and package identification
- Agreed documentation
- Shipment-specific packing scope
Packing method is project-specific.
We confirm the packing method for the selected equipment before shipment.
Quality Control FAQ
Common Questions About Magnetic Separator Quality Control
A useful test plan removes ambiguity before the equipment reaches the plant. The questions below connect each measurement or inspection to the purchasing decision it can support.
Can a Gauss reading prove magnetic separator performance?
No. It confirms magnetic flux density at the defined measurement point and method. Separation performance also depends on the target material, working distance, burden depth, feed presentation, separator geometry and operating conditions.
Can a pull-force test replace a material trial?
No. A pull-force test is a controlled mechanical comparison using a defined test piece and method. It does not reproduce the motion, presentation or fraction collection of real process material.
Should every Corvelan magnetic separator use the same QC checklist?
No. Inspection points should follow the actual equipment type and project scope. A passive magnetic grate, magnetic drum and driven overband separator have different mechanical, magnetic and electrical requirements.
Does a successful factory material trial guarantee production performance?
No. A factory result applies to the tested sample, configuration, method and operating window. If the installed plant changes material condition, feed presentation, working distance, burden depth, speed or discharge geometry, production-side confirmation may still be required.
Can inspection requirements be defined before production?
Yes. Critical dimensions, magnetic measurements, functional checks, material tests, FAT items and required records should be discussed before production when they affect purchasing acceptance.
Can a customer or third party inspect the equipment before shipment?
Inspection arrangements can be included in the project discussion. The inspection scope, timing, access, test method and acceptance basis should be agreed before the visit or third-party inspection is scheduled.
