This machine is vertical and it is small and simple to operate.This machine crushes fertilizer evenly .It has good corrosion resistance because of the rubber lining in inner wall( as we all know,either compound fertilizer and organic fertilizer are corrosive ). For the same reason,even material with much moisture doesn’t stick the wall with rubber inner wall. So it is easy to clean. There is no screen on discharge of output because screen will cause sticking. But two-graded crushing function will ensure the crushing effect. Feed inlet is upper and crushed fertilizer comes out from below.
