Pelleting press has rotating annular die with press openings - contg. pressure rollers freely rotatable on shafts with ends in eccentric discs rotatably adjustable by actuators to vary roller-die spacing

摘要

the pelleting press comprises a rotatably driven (A) annular die with radial openings and containing pressure rollers which operate in conjunction with the inner die surface and are freely rotatable on respective shafts each provided with an eccentric such that rotation thereof varies the position of the roller relative to the die. This rotational adjustment is effected by 2 respective cylinder/piston actuators which preferably have their piston rods provided with 2 forked yokes enclosing eccentric pins on the eccentrics with clearance whereby these pins may (additionally) be adjustable in circumferential direction relative to the shafts.
