Power Source Guide You can order Bunting Plate Magnets with the magnetic material best suited to your application. Our high-density Ceramic magnets are the practical choice for most separation applications. Compact, lightweight Neodymium Rare Earth magnets offer the extra magnetic energy you may need to capture extremely fine or weakly magnetic contaminants or to handle high flow rates and dense material. Easy Installation Bunting Plate Magnets come with an installation kit consisting of hinges, latch, self-locking hardware, and instructions to ensure professional results. Unless otherwise specified, units weighing over 50 lbs. come with lifting lugs for supporting the magnet during installation or for customer mounting. General-purpose or food grade gaskets are available. Request installation drawings to check hole and cutout locations. Construction Standards Bunting has established construction specifications for Utility, Powder, Food, and Sanitary Grades. All Plate Magnets and options are available in all construction grades. We will be glad to send detailed information to help you select the right model and options for your application.

How to Select and Order Bunting Plate Magnets
The following steps will help you select and order a Plate Magnet that’s right for your chute or spouting application. As you go from step to step, jot down the selections you make: The eight-part Plate Magnet Model Number is made up of coded entries for your selections. The first part of the Model Number is PM for Plate Magnet. The second part is a code for the magnet that meets your product flow rate needs. The third part is a two-digit entry for the width you select. The remaining parts of the Plate Magnet Model Number are explained below, along with the selection steps. Here’s a sample Model Number to show you what a complete one looks like.

If you have any questions or want additional guidance in making your selections, call us at (800) 835-2526. We’ll be glad to help you make the right choices.

Step 1:
Estimate the maximum flow rate through your chute in cubic feet per hour. Then use the Ceramic or Rare Earth Adjustments tables to adjust this flow capacity for the size of tramp iron you encounter and your chute angle. If the magnet will be more than two feet from the feed opening of a chute, increase required capacity by 10% for each additional foot. If you intend to mount two identical magnets within 6" of each other, reduce the required magnet capacity by 50%. This new figure is your revised maximum flow rate estimate.

** Consult Bunting for suspended applications

Step 2:
Determine the widest Plate Magnet your chute or spouting will accommodate. Because of the mounting flanges, the actual width of the magnet face is 2" less than the Plate Magnet’s overall width. This can create an area of unprotected product flow. To get maximum protection, consider getting a full-width magnet and using angle-iron mounts as shown in the illustration to the right.

Step 3:
Now that you know what width you want and have a reasonable estimate of flow rate, look over the Plate Magnet Capacities and Weights table to see which magnets are in your ballpark. First, find the width that’s closest to the width of your chute or spouting, and look across the adjacent row of flow rates for the capacity that’s closest to the maximum capacity you’ve estimated.

Notice that both Ceramic and Neodymium Plate Magnets come with three flow rate capacities for each width. These three strength levels are represented by model numbers. The model numbers (C30, C45, C65 and N35, N50, N65) indicate the vertical reachout of the magnetic field. For example, C45 has a 4.5-inch reachout; N50 has a 5.0-inch reachout. Select the reachout that most closely corresponds to the depth of your chute or spouting.

Neodymium magnets cost more than Ceramic, but Neodymium magnets can be from 40% to 60% lighter than Ceramic magnets with similar flow rate capacities. Think about where you will install the magnet, your spouting’s ability to carry its weight, and the possible difficulty or danger a heavy magnet might pose to workers. Then make a preliminary choice between Ceramic and Neodymium and write down the model with the capacity and reachout you need plus the width you’ve chosen before moving on.

Plate Magnet Face Styles Plate Magnets have stainless steel exteriors and come in three face styles and six magnetic strengths to cover a wide range of applications. All magnetic loads have been redesigned to deliver up to three times the surface holding force while still maintaining the same powerful reachout. Faces of pole and tapered step models are constructed of 410/416 magnetic stainless steel and especially well suited to holding captured tramp and fines securely in place. Self-cleaning units are available in tapered step and flat face styles. Flat Face Model is especially recommended for maintaining a sanitary environment. For low-density product applications and inverted installations. Pole Face Model features two exposed pole plates to capture and hold contaminants. For low-density product applications. Tapered Step Face Model is specifically designed to hold ferrous debris against its solid tapered step to prevent wash-off of tramp iron and fines even when product flow is rapid. For high-density product applications.

Step 4: Refer to face style illustrations A, B, and C at left. If you plan to select the Manual Self-Cleaning Plate Magnet, choose tapered step or flat face. Otherwise, choose any of the three that will work best for you. PM C65 24 P M H U S For Part 4 of the Model Number, enter your Face Style choice: F Flat Face P Pole Face T Tapered Step Face

U	Utility Grade (50 spec) is suitable for general-purpose applications.
P	Powder Grade (100 spec) is used for powdery solids.
F	Sanitary-Food Grade (200 spec) is the preferred finish for the food industry and meets or exceeds FDA construction guidelines. All seams are continuously welded.
S	Sanitary Grade (300 spec) is designed to meet the general requirements of USDA construction standards. The face side is polished, and non-product contact surfaces have a bead-blasted finish. Flat face units are recommended for sanitary applications.

Step 8:
Finally, decide about the self-cleaning option. Manual Self-Cleaning Plate Magnets save time and labor and make routine cleaning much easier. When you turn the handle to the open position, the plate magnet is free to swing away from the chute and from the special separately hinged face plate, as illustrated below. This releases the tramp iron and fines for collection. Choosing this option will limit your choice of face styles to tapered step and flat face.
