Abstract
The present invention relates to a roller crusher having two generally parallel rotatable rollers separated by a gap, and a feeding arrangement for feeding material to the rollers. The roller crusher includes a base frame and a first and a second roller frame section, each of the first and second roller frames sections being pivotably connected to the base frame and arranged for carrying one of the rollers in bearings arranged at opposed ends of each roller. The roller crusher also includes at least one balancing cylinder extending between one of the roller frame sections and the base frame such that when the at least one balancing cylinder is activated, the interconnected roller frame sections will pivot relative to the base frame, thus adjusting the position of the rollers relative to the base frame.
Claims15
A roller crusher having two generally parallel rotatable rollers separated by a gap, and a feeding arrangement for feeding material to the gap between the said rollers, said roller crusher further comprising:
- a base frame;
- a first and a second roller frame section, each of said first and second roller frames sections being pivotably connected to said base frame and arranged for carrying one of said rollers in bearings arranged at opposed ends of said each roller;
- and
- at least one balancing cylinder arranged to extend between one of the roller frame sections and the base frame such that when the at least one balancing cylinder is activated, the interconnected roller frame sections will pivot relative to said base frame, thus adjusting the position of the gap between the rollers relative to said base frame and the feeding arrangement.
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 base frame;
- a first roller frame section including a front roller plate and a rear roller plate, wherein each of the front and rear roller plates are pivotally connected to the base frame and are arranged for carrying one of the rollers;
- a second roller frame section having a front roller plate and a rear roller plate, wherein each of the front and rear roller plates are pivotally connected to the base frame and arranged for carrying one of the rollers;
- a pair of gap adjusting cylinders interconnecting the front roller plates of the pair of first and second roller frame sections and the rear roller plates of the pair of first and second roller frame sections, wherein the gap adjusting cylinders are arranged to adjust the size of the crushing gap between the rollers;
- and
- at least one balancing cylinder connected to one of the roller frame sections, wherein activation of the balancing cylinder pivots the first and second roller frame sections to adjust the position of the crushing gap relative to the base frame and the feeding arrangement.
