Rebound crusher
First Claim
1. A rebound crusher comprisinga crusher housing, a rebound mechanism disposed within said housing, and at least one rotor provided with hammers and being rotatably mounted in said crusher housing, said rotor cooperating with said rebound mechanism, said rebound mechanism being supported swingably against spring force within the crusher housing, the distance from said rebound mechanism to the hammers of the rotor being adjustable;
- and whereinsaid crusher further comprisesadjustment means secured to said crusher housing, and having an adjustment piston and a setting cylinder enclosing said piston,damping means interconnecting said adjustment means with said rebound mechanism, said adjustment means adjusting the distance between the hammers and said rebound mechanism, said damping means damping a motion of said rebound mechanism during a crushing of bodies of material placed within said housing; and
whereinsaid setting cylinder is secured to said housing; and
said damping means comprises a damping cylinder positioned by said adjustment piston, said damping means further comprising a damping piston enclosed within said damping cylinder and being articulated to a part of said rebound mechanism distant from a point of pivot of said rebound mechanism, said damping piston being moveable independently of a movement of said adjustment piston for operation of said damping means and said adjustment means independently of each other.

Abstract
The invention concerns a rebound crusher having at least one rotor provided with hammers which is mounted rotatably in a crusher housing and cooperates with at least one rebound mechanism which is arranged swingable against spring force within the crusher housing and the distance of which from the hammers of the rotor is adjustable. In order, in a space-saving development, to permit remote adjustment of the nip between hammers and rebound mechanism, the rebound mechanism is pivotally connected to the piston rod of a damping piston which rests against the crusher housing and the front end position of which is infinitely variable via an adjustment piston of a setting cylinder.

2. In an impact crusher comprising
a crusher housing and at least one impact mechanism; -
at least one rotor which is provided with hammer arms, said rotor being mounted rotatably in the crusher housing and operative with said at least one impact mechanism, said impact mechanism being mounted swingably in the crusher housing so as to move away upon the presence of large pieces of material to be crushed and particularly foreign bodies; distance means for adjusting the distance of the impact mechanism from the hammer arms of the rotor, the impact mechanism including a setting cylinder, and a piston rod and a setting piston connected together and disposed in the setting cylinder;
the impact mechanism being connected continuously displaceable in articulated fashion with the piston rod, the piston resting against the crusher housing;
the improvement wherein;said crusher further comprises a damper cylinder and a damping piston connected to said piston rod, said piston rod serving also as a piston rod for the damping piston; and
whereina front end position of the damping piston is continuously displaceable via the setting piston of the setting cylinder; and said setting piston is moveable within said setting cylinder, said damping piston being moveable within said damper cylinder independently of movement of said setting piston within said setting cylinder for operation of said setting piston and said damping piston independently of each other. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12)
