A. Magnetic Plates
Introduction:Plate Magnets are important industrial iron separators that are meant for the
separation of fine ferrous materials and tramp iron, from many types of free-
flowing and pneumatically conveyed material like corn, sugar, flour, gravel, plastic
and others granular materials.

The plate magnets also goes very well with powdery, moist, lumpy, and abrasive
products and large debris that might choke, bridge, or cause rapid wear in
cartridge-based separators. Plate magnets are flexible enough to be deployed
above conveyors or below conveyor drive pulleys to capture contaminants.They are available in both flat and curved shapes and could be installed either
above or at discharge end of material flow. These plates are constructed with
Strontium Ferrite Magnets as well as with high energy Permanent Magnets placed
in a magnetic circuit. They are extensively used in CTC Tea machinery and in
Biscuit stacking machines. They can be manufactured for required dimensions.Magnetic plates are used for separation of trapped iron in industries such as:
Food (Tea, Spices, Coffee, Cocoa, Milk Powder etc.) Tobacco Chemicals Fertilizers Pharmaceuticals Foundry Sand Cattle Feed Materials Minerals Detergents Conveying of light weight tin containers Conveying of M.S. sheets using multiple plates
Lighter-duty Plate Magnets offer cost-effective choices for applications with lower
product flow rate, lower conveyor speeds, or thinner burden depths. Magnetic
Plates with Strontium Ferrite Magnets / Rare Earth magnets can attract metal
particles from thin layers of product conveyed on flat belts from distance of 6. . Attract ferrous tramp from flat-belt. Powerful Ceramic magnet reaches deep into conveyed material upto
6.Threaded holes are provided for easy mounting of these plates with other
convenient option.How does it work?

For Iron Removal Magnetic Plates are generally located above the material flow.
While flowing iron particles are attracted by the plate. The magnetic field
penetrates the product flow and grabs tramp iron as it passes by the Plate. The
concentrated field holds tramp iron tightly to the magnet surface until removed
during the cleaning process.For Holding of Ferro Magnetic material like Tin/M.S. sheets, containers as they
are conveyed by the conveying belt multiple Magnetic Plates at number of
locations are used. This prevents the falling off sheets/containers from the
conveyor.

Features: Efficient cost-saving recovery of harmful tramp iron in free-flowing materials. Plate magnets can be mounted both, above or below the product flow. Magnets like ceramic or rare earth magnets are normally used in plate. Magnetic separators as they capture maximum common ferrous debris. Durable stainless steel construction. For easy cleaning hinged plates can be swung out. The plate magnets can be cleaned both manually. They are simple to install and have no maintenance Lightweight and user-friendly
Specification: The compact design of these powerful magnetic separators makes them simple. Standard installations involve hinged models for swingopen cleaning. Plates are also available without hinges for stationary or suspended installations. Rare Earth is standard for food and pharmaceutical applications where product
purity is paramount.
There are two Types of Plate Magnets:a. High intensity - (Ndfeb Magnet 4500 gauss)b. Low intensity - (Ferrite Magnet 1200 gauss)
Construction:
Magnetic Plates are available in flat and curved shape with required dimensions.

Introduction:PML Suspended Magnets are placed above open conveyors to arrest ferrous
objects and fines found in grains, feedstuffs, raw and processed products, drychemicals, salt, ceramics, Clinkers in Cement Industry, Coal conveying in power
plants and many other products.Overband Magnets are used for separation of big Ferrous particles like lugs, nuts,
bolts, rivets, ms plates, angles, channels and tools from moving material in
conveyor belt. It is used in industries like: Cement Coal Handling Plant Salt processing industries Glass Paper Refractory Minerals (e.g. Bauxite)
How does it work?
Overband Magnet is placed over the conveying belts carrying the material. This
system arrests Ferromagnetic materials from distance of 300mm/12 inches from
feed material which is transported through the production process.Construction:

Overband magnets are generally in big sizes depending upon the width and speed
of the conveyor belt. They are provided with eye bolts, D shackle and sling chains
with turnbuckles for adjustments while mounting.Specification:
Flux density: 1500 200 gauss Lifting Distance: Upto 300mm/12inches
Besides customized Overband magnets, PML also supplies standard Overbandmagnets as below:
Sr Size (LxWxH) in mm1 650x650x2452 800x800x2453 1000x1000x2454 1200x1000x245
Why PML Overband Magnet? 45 years of experience in design and development of Permanent Magnets and
Magnetic Systems.
Mounting chains are tested and certified for load bearing capacity by a governmentapproved testing Authority.
Customized Design Services such as magnetic calibration/Audit are available.
