ABSTRACT:
This invention relates to an improvement in a single-roll crusher having a housing, a roll body freely rotatably supported on an eccentrically rotatable drive shaft in said housing, at least one laterally mounted crushing beam pendularly suspended in the upper part of said housing and resting in the lower region thereof at approximately the height of the roll body axis, by means of a pressure bar, against a prestressed set of springs solidly integrated in the crusher housing in order to absorb the crushing force, the prestressing force also being adjustable when the set of springs is integrated and the gap adjustment at the exit of the crushing space is achieved by changing the spacer thickness between the pressure bar and a spring retainer, the improvement comprising bayonet lock means holding the prestressed set of springs in the crusher housing, the prongs and mating prongs of said bayonet lock means mutually engaging and releasing each other in assembly and disassembly, and key means pressing the support surfaces of the set of springs in the same direction as the crushing force on corresponding bearing surfaces in the crusher housing.
