PELLETISING PRESS Russian patent published in 2013 - IPC B30B11/20 B30B3/06 

FIELD: process engineering.

SUBSTANCE: invention to material forming and may be used for making pellets from coal fines, peat grit, chips, etc. Proposed press comprises casing to house shaft with forming wheel mounted off-center. Said wheel is arranged between top and bottom flanges. Top flange has offloading opening and check opening arranged there above in bottom flange. Forming wheel is rigidly fitted on shaft, its axis being offset relative to casing axis. Said shaft is installed at plates with bearings, adjustment links and oval holes. Said plates are secured by means of studs and nuts at top and bottom flanges. Flanges are secured to casing. Plate teeth are regularly located on forming wheel outer side. Teeth side surfaces are inclined toward pellet exit through a definite angle to interact with plate teeth of second forming wheel. Second wheel is arranged in casing between top and bottom flanges with minimum clearance to run free therein. Second wheel teeth are regularly spaced on inner surface at the same spacing and with the same inclination at angle a to direction of rotation.

EFFECT: higher quality of pellets, increased press MTBR.
