Problems solved by technology
[0002] The double-roll extrusion granulator has a short process flow, low energy consumption and large output. The dry powder is directly granulated without subsequent drying process, which is more conducive to the connection and transformation of the existing production process. If the material is insufficient or the gap between the rollers is too large, some compound fertilizer particles will not be spherical. It needs irregular manual adjustments to make the equipment work normally. At the same time, the processing of unqualified compound fertilizer particles can still be achieved by re-extruding. The purpose of production, but screening and transportation of unqualified compound fertilizer particles requires more investment in equipment, which increases the cost of input

The invention discloses an extruding machine for compound fertilizer granulation. The extruding machine comprises a processing machine body, wherein a processing cavity is formed in the processing machine body, a stirring box is fixedly arranged on the left side of the processing cavity, a feeding frame is fixedly arranged on the upper side of the stirring box, and a feeding cavity with an upwardopening is formed in the feeding frame. According to the invention, meshing transmission between gears is adopted, so that the granulation rollers which are symmetrical left and right extrude the fallen compound fertilizer to form particles so as to achieve the purpose of granulating the compound fertilizer; the vibrating screen plate is pushed by the cam to vibrate up and down to screen the compound fertilizer particles, so that the compound fertilizer processing quality is effectively guaranteed; and the purpose of feeding the compound fertilizer particles which do not pass through the vibrating screen into the processing cavity again for processing is achieved through the air cylinder and the material pushing rod, so that the processing quality is effectively improved, and the processing cost is saved.
Description
technical field [0001] The invention relates to the technical field of extruders, in particular to an extruder used for compound fertilizer granulation. Background technique [0002] The double-roll extrusion granulator has a short process flow, low energy consumption and large output. The dry powder is directly granulated without subsequent drying process, which is more conducive to the connection and transformation of the existing production process. If the material is insufficient or the gap between the rollers is too large, some compound fertilizer particles will not be spherical. It needs irregular manual adjustments to make the equipment work normally. At the same time, the processing of unqualified compound fertilizer particles can still be achieved by re-extruding. The purpose of production, but screening and transportation of unqualified compound fertilizer particles requires more equipment, which increases the cost of input.
