Product Details
A fixed grill has to be lifted out of the line to inspect or clean. The PML Drawer Type Magnetic Grill solves that by mounting the magnetic elements on a sliding drawer inside a stationary housing — pull the drawer, clean it, slide it back, without disturbing the duct connections. It's built for the same job as our standard grill — trapping iron particles from dry, granular or free-flowing material — in a format designed for lines where the grill needs checking often.
Stainless Steel 304/316 throughout, with magnetic elements in hard ferrite ceramic or high-intensity rare-earth NdFeB, sized to your duct or chute.
Single or Double Drawer
Single-drawer units handle contamination within roughly 1–1.5% by weight of the product. Where contamination runs higher, a double-drawer unit — with more magnetic elements across two drawers — keeps the grill effective without needing more frequent cleaning.
Customized double-drawer builds are also available for higher-throughput lines:
Standard Range — High-Intensity (11,000 ± 500 Gauss) & Super High-Intensity (12,000 ± 500 Gauss)
| Single Drawer, High-Intensity (Model prefix HSDG) | ||||
|---|---|---|---|---|
| Model No. | Dia. A (mm) | Height B (mm) | Magnetic Elements | |
| HSDG1 | 100 | 165 | 3 | |
| HSDG3 | 200 | 165 | 5 | |
| HSDG5 | 300 | 165 | 6 | |
| HSDG7 | 400 | 165 | 8 | |
| Double Drawer, High-Intensity (Model prefix HDDG) | ||||
| HDDG1 | 100 | 250 | 5 | |
| HDDG3 | 200 | 250 | 9 | |
| HDDG5 | 300 | 250 | 11 | |
| HDDG7 | 400 | 250 | 15 | |
Both single and double drawer units are also available in Super High-Intensity (12,000 ± 500 Gauss) at the same diameters, and in intermediate sizes (150mm, 250mm, 350mm) not shown above — the full range runs 100mm to 400mm in 50mm steps.
Key Advantages
- Clean Without Disconnecting
The drawer slides out for cleaning while the housing stays fixed in the line.
- Single or Double Drawer
Scale the number of magnetic elements to your contamination load.
- Four Intensity Grades
From standard high-intensity up to 12,000 Gauss super high-intensity.
- High-Temperature Options
Rated up to 350°C with Samarium Cobalt (SmCo) magnets for hot process lines.
Where It's Used
Plastics, food processing (sugar, coffee, tea, grains, pulses, flour, spices, milk), pharmaceutical, chemical, ceramic, colours and paints, pigments, ink, refractory and mineral processing.
Frequently Asked Questions
Single or double drawer — which do I need?
Single drawer suits contamination up to roughly 1–1.5% by weight. Above that, double drawer adds more magnetic elements so the grill stays effective between cleanings.
How hot can the process be?
Standard units run to 80°C (NdFeB) or 250°C (ferrite); with Samarium Cobalt magnets, high-intensity units are rated up to 350°C.
Can the drawer be cleaned without stopping the line?
The drawer needs to be withdrawn to clean, so the line segment it's fitted to should be briefly isolated — but the housing itself stays connected, so there's no re-plumbing each time.
