FIELD: process engineering.SUBSTANCE: invention relates to press equipment for production of pellets from appropriate material. Pelletiser comprises carcass with main axle fitted therein, ring-shaped female die, rolls holder with axles running thereon. Pelletiser incorporates the drives. Every drive can inhibit roll axle displacement relative to female die holder to maintain the spacing between roll and die before application of force to roll axle that corresponds to pelletiser overload. Note here that said every drive includes hydraulic cylinder equipped with bypass valve connected therewith.EFFECT: accelerated operation, simplified overload protection.20 cl, 5 dwg |
