Description

Technical Field

[0001] This utility model relates to the field of granulator technology, specifically a double-roller granulator. Background Technology

[0002] A granulator is a molding machine that can shape materials into specific shapes. Traditional double-roll granulators have grooves on the surfaces of both rollers. The two grooves correspond one-to-one and form a granulation space. The two rollers move towards each other to compress and shape the material, thereby completing the granulation process.

[0003] Utility model CN213913647U discloses a double-roller granulator, which includes a first roller, a second roller, and a power mechanism. The first roller has a first cylindrical body fixed to a first rotating shaft and rotatable around the shaft. Multiple first grooves are formed on the outer surface of the first cylindrical body. A first elastic layer is attached to and covers the outer surface of the first cylindrical body. A first pressing layer is attached to and covers the outer surface of the first elastic layer. Multiple first through holes are formed on the outer surface of the first pressing layer. When the first elastic layer is pressed to fit against the surface of the first groove, the first through holes communicate with the first groove to form a first half-cavity. The second roller has a second rotating shaft arranged parallel to the first rotating shaft. The power mechanism drives the first and second rollers to rotate, so that the first half-cavity communicates with the second half-cavity to form a granulation chamber.

[0004] The above-mentioned technical solution allows the roller granulator to form and discharge materials with low dryness well, resulting in good processing effect. However, the roller granulator is not convenient for crushing and refining large particles during granulation, the overall assembly is inconvenient, and it is not easy to observe the internal granulation status in real time. After granulation, it is not easy to guide the discharge to reduce the impact of particle accumulation. Utility Model Content
