Product Details
At a Glance
A drawer type easy clean magnetic grill uses the same drawer-and-housing platform as PML's standard Drawer Type Grill, with multiple drawers arranged to handle a higher share of fine ferrous particles and an interlock so the rod loses contact with the magnetic circuit the moment it's slid out for cleaning. It's built for chute discharge points where fine contamination outpaces a standard drawer grill.
When fine ferrous particles make up a bigger share of your contamination than a standard drawer grill is built for, the PML Drawer Type Easy Clean Magnetic Grill steps up. It uses the same drawer-and-housing platform as our standard Drawer Type Grill, but arranges multiple drawers in alternating loops of magnetic rods — giving fine iron and paramagnetic particles more chances to get trapped as sugar, grain, flour, granulates and powders pass through.
How the Easy-Clean Mechanism Works
The unit is designed for chute discharge points and fitted with an interlock. To clean it, remove the drawer with its magnetic rod, slide open the lock, and slide the rod out of the hollow stainless steel sleeve it rests in. The sleeve stays stationary and immediately loses contact with the magnetic circuit, so trapped ferrous particles simply fall away into a collection bin — no scraping. Two guided rods keep the drawer sliding smoothly through the whole cleaning cycle.

Key Advantages
- Built for Higher Fines Loading
Multiple alternating drawer loops give fine ferrous particles more opportunities to be captured than a single-drawer design.
- Fast Cleaning
The sleeve-and-rod design drops trapped iron instantly on withdrawal — no manual scraping.
- Maintenance-Free
No power, no wear parts beyond periodic cleaning.
- Custom Configurations
Drawer count and sizing can be tailored to your contamination profile and chute geometry.
Where It's Used
Pharmaceutical, chemical, agrochemical, food, petrochemical, power, steel, cement and waste treatment industries — anywhere fine ferrous contamination needs to be trapped from dry, free-flowing material at a chute discharge point.
Frequently Asked Questions
How is this different from the standard Drawer Type Grill?
Both use the same drawer-and-sleeve platform, but this version arranges multiple drawers in alternating loops specifically to catch a higher proportion of fine ferrous particles.
Where does it get installed?
Primarily at chute discharge points, arresting iron particles as product flows out of storage or process equipment.
Can I get a custom drawer configuration?
Yes — beyond the seven standard sizes, custom drawer counts and dimensions are available to match your fines loading.
What Gauss rating does it use?
9,000 ± 500 Gauss, with a maximum operating temperature of 80°C.
How many magnetic elements does each size have?
From 3 elements on the smallest (100mm) model up to 8 elements on the largest (400mm) standard model — see the table above for the full range.

Why Magnetic Strength Drops in Ferrous Separators (and When to Replace)
Separation efficiency falls as magnetic strength decreases. Below are the most common causes of reduced field strength in NdFeB (neodymium) magnetic separation equipment, along with the warning signs that indicate a magnet or separator needs replacing.
Causes of Reduced Magnetic Strength
- Thermal demagnetization: Standard Neodymium-Iron-Boron (NdFeB) grades lose magnetic strength when exposed to temperatures above their rating — often starting at 80°C / 176°F for standard grades. Exceeding these limits causes a permanent loss of magnetic flux.
- Corrosion and core oxidation: NdFeB is highly iron-rich and oxidizes quickly. If moisture, washdown liquids, or corrosive chemicals breach the outer stainless steel cladding, the magnet swells, crumbles, and loses field strength.
- Mechanical damage and internal cracking: NdFeB is brittle. Dropping magnetic tubes during cleaning, or subjecting them to heavy equipment vibration, causes internal micro-fractures that break the continuous magnetic circuit.
- Strong opposing magnetic fields: A sufficiently strong opposing field can overcome a material's coercivity and flip or randomize its magnetic domain polarity. High alternating current (AC) electric fields, in particular, create powerful local alternating magnetic fields that rapidly scramble domain alignment.
- Material buildup ("air gap" effect): Accumulated fine iron on the surface acts as a barrier, pushing the active magnetic field further away from incoming material. Because magnetic force decays exponentially with distance, even a few millimetres of buildup severely reduces capture rates.
- Increased process velocity or burden depth: Running material too fast, or in overly thick layers, prevents fine ferrous particles from spending enough time in the peak magnetic field zone to be pulled out of the flow.
Signs an NdFeB Magnet or Separator Needs Replacing
- Drop in gauss rating: Annual or semi-annual gauss testing shows a permanent drop of 10–15% or more from the baseline specification.
- Bulging or "pillow" swelling: The protective stainless steel tube cladding looks warped, swollen, or cracked — a sign of internal oxidation where rust has expanded inside the shell.
- Dead spots along the field: Measuring with a gauss meter reveals localised spots with zero or drastically lower magnetic pull across the grid or tube surface.
- Downstream metal contamination: Ferrous fines or tramp iron start showing up in final product testing or downstream machinery detectors despite the separator being clean.
- Structural casing punctures: Scratches, gouges, or pinhole leaks in the stainless steel jacket expose the internal magnetic circuit to moisture and process fluids.
Regular gauss testing (at least annually) is the most reliable way to catch strength loss before it affects downstream product purity — PML's own range of Gaussmeters and magnetic field meters covers this. If you're seeing any of the signs above, talk to our team about testing or replacing your separator.
