A jaw crusher has frame side walls, a rear end connected to the side walls, an eccentric supported by the side walls, a pitman supported by the eccentric, a toggle plate connected between the pitman and a middle section of the rear end including a cross wall. The rear end has a rear end support connected to the cross wall and located on a center plane of the cross section of the rear end. An upper and lower rear cross beams are fixed to the side walls. The upper and lower rear cross beams each have a vertical wall and horizontal ribs connected to the vertical wall. A crushing plant is also disclosed with a body and the jaw crusher mounted on the body.

Jaw crusher and crushing plant

A jaw crusher including a body, a fixed jaw, a shaft which is arranged horizontally and in direction of a crushing surface of the fixed jaw, and a pitman which is eccentrically movable in relation to the shaft, wherein an electric motor is arranged between the pitman and the shaft. A mineral material processing plant. A method for driving a jaw crusher including a body, a fixed jaw, a shaft which is arranged horizontally and in direction of a crushing surface of the fixed jaw, and a pitman which is forming a crushing chamber with the fixed jaw, the method including moving the shaft eccentrically in relation to the pitman, the method further including the steps of arranging an electric motor between the pitman and the shaft and rotating the shaft by the electric motor.

Driving of jaw crusher elements

A mineral material crusher and method of operating a mineral material crusher that includes: a body, a rotating crusher element, a drive shaft arrangement that supports the rotating crusher element to the body and to rotate the rotating crusher element, and a motor including a rotor for driving the drive shaft arrangement. The motor is formed inside the rotating crusher element and the drive shaft arrangement is configured to form of the rotor a rotating axle that is rigidly coupled with the rotating crusher element and capable of leading torque from the rotor to the rotating crusher element for rotating the crusher element around the drive shaft.

A processing device and method applying the same for processing a coated or uncoated fibrous web is provided. The device comprises a belt configured to extend around a guiding element, at least one counter-element being disposed outside said belt to provide a contact area with the belt, such that the belt and the counter-element establish therebetween a web processing zone for passing a web to be processed therethrough. The processing zone length is defined by the disposition of the belt's guiding element and/or by the configuration of the counter-elements. The contact pressure applied to a web in the processing zone is within the range of between about 0.01 MPa and about 200 MPa.
