The Greenwood Magnetic Grid is used in vibrating sieves for the removal of metal contamination during the sieving process. This metal contamination may be present due to contamination in the raw materials or may be caused by the actual sieving process.
Manufactured to the diameter required they are simply placed in the sieve after the screen. Due to the extremely high gauss strength of these grids (up to 12000 gauss) they are capable of extracting particles down to 30 microns and below. All encased in 316 stainless steel, they are fully welded, polished and finished to food and pharmaceutical industry standards.
