Roller crusher with cheek plates

A roll crusher having two generally parallel rotatable rollers separated by a crushing gap and a feeding arrangement for feeding material to the crushing gap between the rollers, the roll crusher further comprising:

• a stationary base frame;
• a first roller frame pivotally connected to the base frame and arranged for carrying one of the rollers;
• a second roller frame pivotally connected to the base frame and arranged for carrying one of the rollers;
• a stationary feeding arrangement including first and second side plates each having an arcuate lower surface;
• front and rear cheek plates mounted to one of the roller frames for partially covering front and rear end surfaces of one of the rollers and at least partially covering an opening between the front and rear side plates of the feeding arrangement and the two rollers, wherein the cheek plates each include an arcuate upper surface located vertically opposed to the arcuate lower surface of the front and rear side plates such that the upper surface of the cheek plates and the lower surface of the front and rear side plates remain vertically opposed during movement of the roller frames;
• and
• at least one balancing cylinder connected to and arranged to manipulate the roller frames relative to the base frame such that the position of the rollers can be adjusted relative to the stationary feeding arrangement.
