The utility model relates to the technical field of
fertilizer production, and discloses a granulator for producing an organic-
inorganic compound fertilizer, which comprises a stirring
barrel, a first motor is movably connected to the top end of the stirring
barrel, a limiting cylinder is movably connected to the movable end of the first motor, and a stirring rod is fixedly connected to the bottom end of the movable end of the first motor. Three connecting rods are fixedly connected to the surface of the limiting cylinder, a round
pipe is fixedly connected to the bottom end of the stirring
barrel, a valve is arranged on one side of the round
pipe, an
extrusion case is fixedly connected to one end of the round
pipe, a partition plate is fixedly connected to the inner wall of the
extrusion case, a baffle is fixedly connected to the top end of the partition plate, and a
granulation device is arranged in the baffle; the
fertilizer granulation device is compact and reasonable in structural design, solves the problem that fertilizer
granulation is tedious in the prior art that the fertilizer is firstly extruded into blocks and then the
organic fertilizer extruded into blocks is
cut, and reduces the working procedures of fertilizer production, thereby improving the production efficiency of the fertilizer.
