The drive shaft gear imparts a rotational movement of the drive shaft to a first gearing assembly, the first gearing assembly imparting a second rotational movement to a second gearing assembly, the second gearing assembly imparting a third rotational movement of the second gearing assembly to drive a ring gear, and wherein the ring gear is attached to and rotates an eccentric assembly of the gyratory crusher and/or cone crusher. The cone crusher is preferably configured to crush rock, stone, ore or minerals. A method of making or retrofitting a crushing device such as, for example, a cone crusher or other gyratory crusher, is also provided. | 10-27-2011 |
| 20140097282 | GYRATORY CRUSHER WITH PISTON - A cylindrical, hollow piston for a gyratory crusher includes a piston wall, a piston top and a piston bottom. The piston wall includes at least one opening leading into an inner chamber of the hollow piston. The piston wall has an outer sliding surface and an inner chamber surface. | 04-10-2014 |
| 20140103154 | FRAME FOR A GYRATORY CRUSHER - A gyratory crusher includes a frame and a crushing head which is arranged rotatably about a substantially vertical shaft. The frame has an upper frame portion and a lower frame portion. The lower frame portion includes a hub. The hub has a centralized arranged through hole with a center axis extending through the hole and the hub. The hole is arranged to cooperate with the shaft being rotatably arranged in the hole. The hub is connected by arms to the lower frame portion and includes a drive ring pocket. | 04-17-2014 |
| 20150129696 | PARABOLIC VIBRATORY IMPACT MILL - A parabolic vibratory impact mill is proposed which comprises a housing having an outer cone, an inner cone and a power-operated vibrator. The shells of the cones have working surfaces in the form of parabolic generatrices: in the bottom part, the concavity of the parabolae is oriented toward the axis of the mill; in the top part, the convexity of the parabolae is oriented toward the axis of the mill. Conditions are created for the autogenous grinding of large pieces in the top part and small pieces in the bottom part, wherein the material partially decelerates in the transition region between the top parabolae and the bottom parabolae, providing for the metered feeding of the bottom region. The advantageous vertical distribution of the load in the grinding chamber provides a grinding ratio of 30 with little wear on the shells and low energy expenditure. | 05-14-2015 |
| 20150290649 | GYRATORY CRUSHER AND SLIDE BEARING LINING - A gyratory crusher includes an eccentric having an inner slide bearing surface and an outer slide bearing surface, the inner slide bearing surface defining, together with an opposing slide bearing surface, an inner slide bearing. The outer slide bearing surface defines, together with another opposing slide bearing surface, an outer slide bearing. The eccentric is rotatably connected to a crusher frame so as to allow a rotation about an eccentric axis of rotation, which is fixed relative to the frame. The eccentric axis of rotation is defined by one of the inner and outer slide bearings. The inner slide bearing has a total height-to-diameter quotient (H | 10-15-2015 |
| 20150352556 | TWO OIL CHAMBER COUNTERWEIGHT - A counterweight for use in a cone crusher that includes an inner oil chamber and an outer oil chamber to collect lubricating oil during operation of the cone crusher. The counterweight includes a vertical separating wall that receives a splash shield. The vertical separating wall and splash shield define an inner oil chamber while an outer oil chamber is defined by the splash shield, the vertical separating wall and an inner wall of the counterweight. Both the inner and outer oil chambers include drain holes that allow lubricating oil to pass through a generally horizontal floor of the counterweight. The combination of the inner and outer oil chambers allows oil to quickly exit the counterweight into the main oil sump and reduces the amount of oil that gets exposed to the upper seal assembly which reduces the passage of oil past seal assemblies formed in the cone crusher. | 12-10-2015 |

The seal slide ring is connected sealingly to a lower portion of the seal bellows and has a lower slide surface adapted to slide along, and to sealingly abut, with a substantially vertical abutment pressure determined by the inherent weight of the seal slide ring and by the influence of the seal bellows, against an upper slide surface provided on the frame. An upper portion of the seal bellows is sealingly connected to the fastening portion so that rotation of the crusher head causes rotation of the seal slide ring about a substantially vertical axis of rotation. | 12-01-2011 |
