Food Grade Magnetic Grate

Magnetic metal detecting Grates for wet or dry products

Cesco grate magnets are designed for mechanical or gravity fed processing systems where metal trash from nuts, bolts, and miscellaneous hardware to stainless steel fines as small as 0.0001 inches can be captured from product flow by magnetic grids of powerful neodymium rare-earth magnets.

Cesco grate separators are typically fabricated to customer specifications using 304 or 316 stainless steel tubes and frames. Square, rectangular, or circular designs appropriate to the application minimize metal bridging and product build-up when installed in barrels, bins, chutes, hoppers, or other enclosures.

Magnetic Ducts with Grates

Magnetic grates can remove microscopic particles of work-hardened stainless as well as all sizes of ferrous and nickel trash from processing lines. The grates are manufactured with 1" diameter tubing and contain either ceramic or the more powerful rare earth magnets. The tubes are spaced 2" center-to-center which provides a 1" opening for the product flow through. The open spacing between the tubes can be changed from as little as 1/2" to 3" as needed. Deflector bars of various shapes may be added to direct the flow onto the magnetic tubes, thus increasing separation efficiency. Multiple layers of magnetic grates can be used to further increase separation efficiency.

Placing a magnetic grate into a duct reduces the open flow area by about 50%. When more than 50% flow is needed, a MagDuct is required. Because we are constantly asked to solve unique metal removal problems, we are always coming up with new solutions. If you need pads for mounting an air vibrator to the MagDuct body, or maybe special brackets for mounting or locating the unit, we can build them.

Our customization capability prevents us from quoting prices from a pre-printed listing. Once we have the necessary information, we send a design sketch for your approval with price and delivery information. To assist with obtaining the necessary information, be prepared to answer questions such as:

  • What products will flow through the MagDuct?
  • What items need to be removed from the product?
  • What is the flow rate?
  • What is the largest chunk or particle size, or length?
  • What is the size and shape of the ductwork?
  • How much vertical room is available?
  • What type of connections does the MagDuct need?
  • What is the maximum operating temperature?
  • Is there an on/off valve above or below where the MagDuct is to be located?
  • Are any special support brackets needed?
  • What clearance dimension should we know about?
