Abstract
The invention discloses a double-roller pelletizer for discharging by negative pressure. A negative pressure suction device is arranged below two rollers; particles are separated from roller surfaces through suction to enter the suction device; a material-separating sieve is arranged in the suction device; after encountering the material-separating sieve, the particles cannot pass through the material-separating sieve and fall into a storage bin directly. Therefore, the particles are separated from grooves in the roller surfaces through negative pressure suction to enter a collecting device; after the rollers are relatively extruded once to complete one-step pelletizing, the particles do not remain on the surfaces, the next pelletizing efficiency is not affected and the next pelletizing quality is not influenced.
