Problems solved by technology
However, there is a common problem in the above two granulator structures, that is, after the roller granulation is completed, due to extrusion, some particles adhere to the surface of the roller and are not easy to fall off, which affects the granulation efficiency and granulation quality.

The invention discloses a vibrating and discharging double-roller pelletizing machine. According to the vibrating and discharging double-roller pelletizing machine, a roller is a hollow column body and at least one baffle is arranged on the inner wall of the roller, the length direction of each baffle is parallel to the axis of the roller; the height of the baffle is less than the difference between the inner radius of the roller and the radius of a rotary shaft; a heavy object capable of rolling is arranged in the roller. When the baffle is rotated to a lower point, the heavy object is driven and pushed to move upwards; when the at least baffle is rotated to a certain height, the heavy object is released from the limitation of the baffle to fall down to the lower part of the inner wall of the roller to vibrate the roller, so that grains are released from the outer surface of the roller. Therefore, after the roller finishes one-time pelletizing relative to pne-time extruding, the grains are not remained on the surface, and the efficiency of the next-time pelletizing is not influenced or the quality of the next-time pelletizing is not influenced.
Description
technical field [0001] The invention relates to the technical field of granulation, in particular to a vibrating unloading double-roll granulator. Background technique [0002] Granulator is a molding machine that can make materials into specific shapes. It is widely used in chemical, petrochemical, pharmaceutical, food, building materials, mining and metallurgy, environmental protection, printing and dyeing, ceramics, rubber, plastics and other fields. In the prior art, grooves are provided on the surface of the two rollers of the traditional double-roller granulator, and the two grooves correspond one by one to form a granulation space. A screw rod is set in the feeding hopper, and through the rotation of the screw rod, The material is forcibly fed between the two rollers, and the two rollers move towards each other to extrude the material to complete the granulation process. However, the above-mentioned double-roll granulator needs to be equipped with a screw rod, and th...
