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.

The magnetic plates are made of either Ferrite or Ndfeb magnets depending upon

the required flux intensity. The magnetic surface is of Stainless Steel 304/316.Why PML Magnetic Plate?

B. Overband / Suspension Magnets


6/8

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:


7/8

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.
