(a) Structure diagram and (b) functional principle diagram of cone crusher.
The main objective is to investigate the impact of various crushing parameters like feed rate to jaw crusher and eccentric speed of Jaw crusher, closed side setting and throw in cone When the gyratory crusher starts to work, the pinion shaft assembly drives the eccentric rotation of the mantle shaft. The ore enters the crushing chamber from the upper inlet of the crusher, then, under the action of the extrusion of the mantle shaft and the mutual squeeze of the ore, it is crushed and discharged from the discharge port.Simulation and optimization of gyratory crusher

Gyratory Crusher SpringerLink
Gyratory crusher is a crushing equipment that uses the gyratory motion of the crushing cone in the conical cavity inside the shell to extrude, bend, and impact materials, for the purpose of coarse crushing of the materials of various hardness. It was invented in the USA in the 1870s. The equipment specification is usually represented by The TSUV Gyratory Crusher can be connected to FLSmidth’s digital ecosystem, which provides operators with the benefits of both FLSmidth technologies and experience.

Simulation and optimization of gyratory crusher
To study and optimize the gyratory crusher performance, taking the process of crushing iron ore by the gyratory crusher as the specific analysis object in this paper. First, the discrete element method (DEM) analysis model of the iron ore based on the bonded-particle model (BPM) is established. On this basis, the impacts of the mantle eccentric bushing in the eccentric bearing (G) via the countershaft assembly (H). This rotating eccentric bushing imparts an eccentric motion to the main shaft (B), a characteristic of the gyratory crusher. In this way the crushing gap located between the fixed concaves in the crusher shell and the eccentrically gyrating mantle continu -Industrial Solutions Gyratory crushers ThyssenKrupp

ratory crusher, and short-shaft gearless gyratory crusher. The gyratory crusher, whether used as a primary or secondary. is essentially a gravity-type machine. Material flows vertically from top to bottom. It receives a large coarse feed, usually run-of-mine, and its product normally requires additional crushing before produc- ing the finaltop shell of the crusher. The gap is opened and closed by an eccentric assembly in the bottom shell, which causes the central verti-cal shaft to gyrate. The vertical shaft is free to rotate about its own axis. Gyratory crushers are one of the main pri-mary crusher types used in mines and quar-ries. The size designation of gyratory crushersPrimary SUPERIOR® gyratory crushers Wear parts
