Grate Magnets – Plate Magnets
Grate MagnetsGrate Magnet
Grate magnets remove small particles of ferrous metal from free-flowing powders and granular materials. Standard construction features 1″ round tubes filled with either high grade ceramic or rare earth magnets. These tubes and grate magnets can be supplied either unhoused or housed in a variety of configurations to meet the needs of your application.
Our standard products are listed below:
|TUBE||Single tubes filled with ceramic or rare earth magnet material.||Custom-fabricated products or other unique applications|
|GRID||No frame; two cross pieces support magnetic tubes.||Locations too confined for framed type, or for irregular openings.|
|PLAIN FRAME||Magnetic tubes within a four-sided frame||General purpose.|
|HEAVY-DUTY FRAME||Larger, square magnetic tubes; greater surface area; wider tube spacing for this type of grate magnet.||High volume applications, such as grain processing.|
|WING TYPE||Plain frame with wings on sides to funnel material into grate.||General purpose.|
|DRAWER||Drawer can be pulled out of chute for cleaning.||For installation in existing chute.|
|STANDARD||Grate drawer contains magnetic tubes in a housing.||General purpose.|
|EASY CLEAN||Drawer magnets with tube-within-a-tube assemblies||For applications requiring greater cleaning convenience.|
|AUTO CLEAN||Pneumatic system cleans rare earth magnetic tubes automatically.||Inaccessible location, or material with high ferrous contamination.|
|ROTARY||Motorized, with tubes in a circular arrangement.||Prevents cohesive powders and fibrous materials from bridging.|
|HOPPER||Slide gate, transparent drawer face, other industry specific features.||Plastics Industry.|
Locations of Plate Magnets Plate Magnets
If you’re engaged in bulk processing – food, grain, chemicals, plastics, pharmaceuticals, minerals, etc. – protect your valuable equipment and your customers from tramp metal contamination with a plate magnet. The high surface strength of these plate magnets makes them ideally suited for sloping chute applications. These magnets are available as a plate to be installed in an existing process or preinstalled in a variety of Ferroplate equipped products.
Unique design features raised pole pieces to provide better protection. Since the strongest magnetic field on any plate magnet is between the two poles, most of the tramp metal will accumulate in the gap between the poles. The plate magnets’ raised magnetic pole pieces create a recess in this area which holds the attracted metal more securely than designs which have a narrow raised strip between the poles.
Plate magnets are offered in five different styles with varying magnetic strengths to work in a variety of applications:
Ferroplate Model Selection Table
|MAXIMUM DEPTH OF MATERIAL (inches)||3″||3 1/2″||4 1/2″||5 1/2″||6 1/2″|
|Free flowing, dry, loose, granular||2100||2200||2300||2400||Ultimate|
|Dense, wet, viscous, liquid||2300||2400||Ultimate|
Plate Magnet Equipped Products
|For applications where the installation is not in a rectangular, sloping chute, choose from this line of plate magnet equipped products:|
Perma Chute magnets are designed for applications where space is limited, materials can’t pass freely through a grate magnet, or when the chute is too vertical for a plate magnet to work effectively. A Quick Clean model is also available with a built-in drawer for disposing of the separated metal.
Magnetic Hump Plate Magnet
These specially shaped separators are used in rectangular chutes or round pipes where flow speeds and depths exceed the capacity of plate magnets. Hump magnets are recommended if the flow is vertical, or if the angle of the chute is more than 70 degrees. An Easy Clean model with pneumatic self-cleaning mechanism is also offered.
Round Pipe Separator
This separator allows Ferroplates to be used on round, sloping chutes carrying dry material.If has a plate magnet mounted on a rectangular center section, with round adapters on each end.
Round Pipe Magnetic Separator
Hydro Hump Magnetic Separator
Ferroplates in an angled housing remove ferrous contaminants in a liquid pipeline. It has a pressure tight design and 150 lb. flange fittings on both ends.
