摘要： An arrangement for dust blocking in a cone crusher, a cone crusher, and a method for the dust blocking and manufacturing the cone crusher, in which a crusher head is supported by a support cone. A linear actuator vertically moves the crusher head for setting adjustment and/or tramp iron release. A lower surface of the support cone, at least in part, defines a downwards opening annular cavity. The crusher head radially movably supports a seal ring. A lip is formed for the annular cavity by the seal ring. A slip ring extends into the annular cavity beyond the seal ring and forms a counter-surface for the seal ring. The slip ring at least in part defines a pressurised gas supply channel and an entry channelling interconnecting the pressurised gas supply channel to the annular cavity.

摘要： A gyratory crusher including a main shaft that can be installed into a main frame. The gyratory crusher include an alignment system having a stationary dust collar and a separate alignment ring attached to the dust collar. The alignment ring includes a tapered contact surface extending from a lower outer edge to a top edge to help guide a dust seal past the alignment ring and into contact with an outer surface of the dust collar. The dust seal is received within a receiving cavity of a dust seal retainer mounted to the main shaft of the crusher. A series of alignment openings extend through the dust seal retainer to provide access to an outer edge of the dust seal. The position of the dust seal can be adjusted based upon measurements of the outer edge. The main shaft includes a chamfer on the lower end guide the main shaft into a bushing assembly.

摘要： A gyratory crusher and a spider bushing assembly for supporting a spider bushing within the central hub of a gyratory crusher. The spider bushing assembly includes a spider bushing and a means for adjusting the distance between the outer flange of the spider bushing and a support shoulder formed within the central hub of the spider. The means for adjusting allows the position of the spider bushing within the internal bore of the central hub to change while maintaining an interference fit as a result of wear following use of the gyratory crusher. In one embodiment, one or more annular shims are positioned between the bearing support shoulder of the central hub and the outer flange of the spider bushing. Upon wear, one or more of the shims can be removed to improve the interference fit between the spider bushing and the internal bore formed within the central hub.

摘要： A gyratory crusher topshell and topshell assembly including an outer crushing shell and optional intermediate spacer ring. The topshell has a radially inward facing surface that is divided into a plurality of regions including an upper and lower mount region axially separated by an intermediate annular rib. The rib enables the topshell to be compatible with a variety of different sized and shaped concaves optionally using an intermediate spacer ring without the need for a backing compound.

摘要： A gyratory crusher outer crushing shell. The outer crushing shell comprises an upper contact surface region that is divided into a plurality of elongate circumferentially extending shoulders. The shoulders are separated by recessed gap regions adapted to accommodate a suitable backing material to structurally reinforce the shell. A channel extends circumferentially around the shell in the outward facing surface to axially separate the upper contact surface region from a lower contact surface region. The channel is also adapted to accommodate the backing material.

摘要： The invention relates to a cone-shaped crusher including a frame having a cavity, a main shaft disposed eccentrically in the frame, and an eccentric drive making the main shaft perform a gyratory movement. The eccentric drive includes an upper eccentric shaft, a lower eccentric shaft, and an eccentric bearing. The upper eccentric shaft has an opening provided at its central portion to allow the lower end portion of the main shaft to pass through the opening, and an upper coupling part provided at its lower portion and fastened to the lower eccentric shaft. The lower eccentric shaft has a lower coupling part fastened to the upper eccentric shaft. The eccentric bearing accommodates the lower end portion of the main shaft and is disposed in a space defined by the upper eccentric shaft and the lower eccentric shaft.

摘要： A gyratory crusher bearing includes a bearing surface to support rotational movement of a crushing head, wherein a shape profile of the bearing surface at a cross section of the bearing perpendicular to a longitudinal axis of the bearing is substantially circular. A mounting surface is positioned against a bearing support and is orientated to be outward facing relative to the longitudinal axis. A bearing wall is defined between the mounting surface and the bearing surface, the bearing surface defining a central bore extending between a first edge end and a second edge end of the wall. At least one region of the mounting surface in combination with the bearing surface defines the wall between the first edge end and the second edge end and includes a shape profile at a cross section of the bearing perpendicular to the longitudinal axis that is non-circular to define an anchorage region to inhibit rotation of the bearing about the longitudinal axis relative to the bearing support.

摘要： A cone crusher includes a crushing chamber formed between inner and outer crushing shells, a drive shaft that gyrates the crushing head to crush material in the crushing chamber, and a feeding hopper for feeding material to the crushing chamber. A measurement device measures an amount of material present in the feeding hopper. A control system controls, based on the measured amount of material present in the feeding hopper, at least one crusher operating parameter which is chosen from i) an rpm of the drive shaft, and ii) a width of a discharge opening formed between the inner crushing shell and the outer crushing shell.
