摘要:
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.
摘要:
A processing device and a 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 design of the counter-elements. A contact pressure applied to a web in the processing zone is configured to be within the range of between about 0.01 MPa and about 70 MPa.

摘要:
A support structure having a beam portion (2) undergoing bending when the load is imposed on the support structure and a separate elastic member (1a) which deforms elastically in a manner inversely proportional to beam bending from the middle of the support structure towards its ends so that the sum of the deformation produced by beam bending and the deformation of the elastic member is constant, whereby a longitudinal support line in the support structure remains as a straight line even though the support structure itself yields in the direction of the force.

摘要:
A mineral material processing plant includes a frame having two or more upper support surfaces and a jaw crusher including a crusher body having at least two bottom support surfaces at a distance from each other. The processing plant further includes at least one damper to be arranged in between the bottom and upper support surfaces which damper includes a first counter surface for the bottom support surface and a second counter surface for the upper support surface and an elastic material layer between the counter surfaces and preferably a slide joint between the first counter surface and the bottom or upper support surface. A method for damping a jaw crusher in a mineral material processing plant is also disclosed.
