Magnetic filter are commonly used in slow, free flowing materials such as water, grain, food, spices, plastic and chemical fertilizer. The rods can be installed individually in one row or multiple rows. Standard spacing between the rods are 2-inch horizontally and vertically center-to-center. When multiple rows are needed for better separation, the rods should be staggered. Other center-to-center arrangements can be accomplished depending on product flow characteristics and flow rates. The rule of thumb for determining the center-to-center distance is that installations must not cause product bridging and must allow easy access for cleaning.
These magnets are provided in different strengths and lengths. Multi rows of magnetic rods with Ceramic 5 magnetic load (2,500 Surface Gauss) are suited to capture large ferrous metals (i.e. nuts, bolts, washers, nails, etc.).
Magnetic rods with Neodymium magnetic load are recommended for applications where ferrous metal contaminants are much smaller (i.e. metal chips, stables, metal shavings, etc.). Magnetic Hold offers several magnetic rods with neodymium load for your application. The stronger magnetic rods are highly recommended for food and pharmaceutical products.
