The invention relates to a crusher plant, in particular a jaw crusher, including a crushing unit for crushing mineral material, the crushing unit comprising a crushing chamber, to which a crusher outlet is assigned, via which crushed material exits the crushing chamber, at least one actuator being provided, by which the opening size of the crusher outlet is adjustable in the event of an overload situation in the crushing unit, in order to discharge faulty material from the crushing chamber, a belt conveyor being provided after the crusher outlet in the material conveying direction, faulty material being transportable by the belt conveyor from the crusher outlet, following an overload situation, toward a transfer end of the belt conveyor, a detection device being provided, by which the overload situation of the crushing unit or an operating change of the crushing unit brought about as a consequence of the overload situation is detected and an overload signal is then generated, and a control device controlling the belt conveyor and/or monitoring the faulty material transported on the belt conveyor by taking into account the overload signal. According to the invention, it is thus possible to restore the operational readiness of the crushing plant quickly and in a simple manner following the occurrence of an overload situation.

A rotary crushing apparatus includes a container (including a stationary drum, a rotating drum, and a top plate) into which a processing object containing raw material soil is fed. A rotating shaft extends in the vertical direction, and an impact member rotates in the rotating drum by the rotation of the rotating shaft to crush the processing object. Then, the rotating shaft is provided in such a way as to penetrate the top plate 10a, and the rotating shaft is rotatably held via ball bearings provided in the vicinity of the top plate. In addition, the lower end of the rotating shaft is a free end.

A machine such as a material processing apparatus comprises a mechanical transmission system coupled to a mechanical load such as a crusher. An internal combustion engine is coupled to the mechanical transmission system, and at least one motor-generator is coupled to an electrical system and to the mechanical transmission system. In at least one mode of operation, the electrical system delivers electrical power to the motor-generator(s), the motor-generator(s) generating mechanical power from the electrical power and delivering the mechanical power to the mechanical transmission system to drive the mechanical load.

A machine for cleaning regeneration chambers of furnaces, the regeneration chambers having stacks of hollow refractory elements delimiting vertical passages, which define chimneys includes a self-propelled support structure to be introduced into a compartment, below the regeneration chamber to be cleaned, which communicates with the regeneration chamber. The machine further includes at least one lance, applied to the self-propelled support structure and configured to send within the vertical passages a stream of cleaning material powder and compressed air generated by a compressor positioned outside of the regeneration chamber to be cleaned, and at least one suction mouth, applied to said support structure and configured to suck cleaning material dust and aspirable materials from the ground, which were removed during the cleaning operation. At least one video camera is mounted on the support structure and at least one monitor controls from outside, through the video camera, operation of the machine.

A machine such as a material processing apparatus comprises a mechanical transmission system coupled to a mechanical load such as a crusher. An internal combustion engine is coupled to the mechanical transmission system, and at least one motor-generator is coupled to an electrical system and to the mechanical transmission system. In at least one mode of operation, the electrical system delivers electrical power to the motor-generator(s), the motor-generator(s) generating mechanical power from the electrical power and delivering the mechanical power to the mechanical transmission system to drive the mechanical load.

A horizontal grinder chipper with interchangeable rotors which allows for rapid changing of said interchangeable rotors. Where the interchangeable rotors each are in the form of a cassette which can be easily inserted into and in between a first frame portion 1302 and a second frame portion 1303. A hydraulically actuated pivoting clamshell cassette covering upper portion 920 configured to pivot to an open orientation for removal of a first rotor cassette and for insertion of a second rotor cassette.

A vehicle can be equipped with a size reduction device whereby input is directed, such as with a loading system, up and into an inlet of the size reduction device or a storage body to await loading into the size reduction device, such as with a transfer system. The input is reduced in size to be particulate and then either discharged from an outlet or into a storage body for later removal, possibly with a transfer system.

Such a mobile recycler that an operator can replenish a reducing agent tank with a reducing agent from the ground is provided. A reducing agent tank stores a reducing agent supplied to an exhaust gas treatment device treating an exhaust gas from an engine through reduction reaction. A tank case accommodates the reducing agent tank. The tank case has a support base supporting a container of the reducing agent for replenishment to the reducing agent tank.

A crusher unit includes a mainframe that supports a crusher suitable for crushing bulk material. The unit has a primary motor carried by the frame to drive a crusher via a first drive belt extending around a first drive pulley and a first flywheel mounted at the crusher. The unit further includes a secondary motor carried by the frame to provide a secondary drive to the crusher via a second drive belt extending around a first or a second flywheel mounted at the crusher and a second drive pulley.

A cone or gyratory crusher, including a slip ring, a crusher head, and a first sealing member, arranged between the slip ring and the crusher head, defining a first space above the first sealing member. A first flexible member is connected to the first sealing member and defines a second space below the first sealing member.
