Zida zophatikizira feteleza zimagwiritsidwa ntchito popanga feteleza wapawiri.Manyowa ophatikizika ndi feteleza omwe amakhala ndi michere iwiri kapena kupitilira apo, makamaka nayitrogeni, phosphorous, ndi potaziyamu, m'chinthu chimodzi.Zida zophatikizira feteleza zimagwiritsidwa ntchito posintha zinthu kukhala feteleza wa granular omwe amatha kusungidwa mosavuta, kunyamulidwa, ndikuyika ku mbewu.
Pali mitundu ingapo ya zida zapawiri feteleza granulation, kuphatikiza:
1.Drum granulators: Izi zimagwiritsa ntchito ng'oma yayikulu yozungulira kuti apange ma granules.Zopangira zimawonjezeredwa ku ng'oma, ndipo kugwedezeka kwa ng'oma kumathandiza kupanga ma granules.
2.Double roller extrusion granulators: Izi zimagwiritsa ntchito ma roller kuti akanikizire zopangira kukhala ma granules.Kuponderezedwa kwa ma rollers kumathandizira kupanga ma granules ophatikizika, ofanana.
